If someone in TV-land is referred to as "the doctor", it means he's a medical doctor. It might not be explicitly mentioned, possibly even outright denied, but anyone called the doctor seems to be able to deliver any and all surgical operations and medical Techno Babble required by the plot. There are no exceptions (well, other than him). All those other guys who've got doctorates in science, law and philosophy are helpfully distinguished from real doctors with vaguely-academic titles like "professor", if they're even awarded one at all.
This trope stems from a modern convention: in the past, "Doctor" had a purely academic connotation — the word itself derives from the Latin doctor, meaning "teacher". At some point, the word (in English, at least) began to shift from being the title of a learned person/a person with a doctorate to meaning the same as "physician". Originally, the M.D. was a doctorate in medicine, but in some places, like the US and Canada, it became the first professional degree. (In the UK and Ireland an MB ChB — bachelor of medicine & surgery — are the first undergraduate degrees; holders are addressed as "Doctor" regardless. While Surgeons — which require a graduate degree, equivalent to a North American MD in length of education — are only addressed as Mr, Mrs, or Miss in a form of reverse snobbery.)note Historically, being a doctor (the equivalent to GP today) was considered a more upper-class and gentlemanly career than surgery, as they do not have to get their hands dirty. Most surgeons were simply working-class barbers. However when the modern era rolled around and surgery become a more specialized and prestigious line of work than mere doctoring, the surgeons refused the title of Doctor as a sort of passive-aggressive middle-finger to the snobs who denied them the title 300-ish years previously. It is easy to see how the term "doctor" was slowly divorced from its academic roots. This has gone so far that it is common for it to be thought that "real" doctors are physicians... which brings us to this trope. And MD Envy to boot.
Certain professions blur the line. A psychiatrist or forensic pathologist will necessarily have a medical doctorate, but their main occupation isn't taking care of people's cuts and sniffles. If they're suddenly forced to act like that kind of doctor—like, say, they're on hand when someone gets hit by a car—expect them to act awkward and unsure before they save the day. In all likelihood, after all, it's been years since they had to give much thought to the treatment of physical injuries.
Not to be confused with Morally Ambiguous Doctorate. See also Open Heart Dentistry and Omnidisciplinary Scientist. Compare All Monks Know Kung-Fu (which is, basically, Not That Kind Of Monk) and Not That Kind of Mage, where someone good at one form of wizardry is unskilled at another. Contrast with Super Doc, when the Doctor can heal you no matter what his field is.
Note that this trope holds water only in certain languages, such as English; other languages were smart enough to create different words to distinguish between MDs and PhDs. An example would be Chinese, where the medical professionals are addressed as [Surname] yīshēng while academics get [Surname] bóshì.
Doctors who really do practice medicine:

Anime / Manga
Dr. Shiouji from Excel♥Saga specifically states that out of his many doctorates none are in medicine, but it doesn't matter that much in the end as he's also an Omnidisciplinary Scientist who knows all the medical terminology and has previously dissected Iwata's dead body to translocate his brain into a mechanical vessel.
Dr. Kabapu has never said what kind of doctor he is either.
Reversed in Sayonara, Zetsubou-Sensei, when Kafuka Fuura walks into the Itoshiki Clinic for a check-up and initially sees Dr. Mikoto Itoshiki, whom she initially confuses for his younger brother/her teacher Nozomu.
Note: In Japanese, sensei means "professor" or "physician". Compare with the English term "doctor".
Dr. Itoshiki: Yes.
Kafuka: No, I mean, Sensei!
Dr. Itoshiki: Yes?
Kafuka: I mean, Itoshiki-sensei.
Dr. Itoshiki: Yes.
The female Dr. Light started out as Not That Kind Of Doctor, being an astrophysicist. Then, she was later shown as That Kind of Doctor, working in a hospital and healing a fellow hero. Thus began her upgrade to Omnidisciplinary Scientist...
Doctor Strange, from the Marvel Universe, is a trained (though not currently practicing) surgeon. (Specifically, he was a neurosurgeon, but an accident left his hands unable to hold a scalpel steady enough to do the fine manipulation necessary for such delicate surgery.) On the occasions when he does show his medical chops, he tends to be better and more versatile than a specialist forty years out of practice should be.
His parody in Fanhunter, Dr. X-Traño (a mix between a real wizard and a cosplayer Marvel geek), is only honoris causanote indicates an honorary degree of something else by Miskatonic University. His allies believed X-Traño to be an M.D. like Strange; he was forced to tell the truth when he was asked to heal an ally.
Inverted with the Night Nurse, who is actually a licensed physician but prefers the catchy codename to "Night General Practitioner"
Directly invoked in the Secret Wars, when Molecule Man is skewered by Wolverine and Volcana says to Dr. Octopus, "You're a doctor, do something!" and he angrily replies that he's a nuclear physicist and not an MD.
Dr. Michael Morbius is actually both kinds of doctor: he is an M.D. with a specialty in hematology, and he has (at least) one doctorate. He has been described as a brilliant biologist, biochemist and radiologist with a Nobel Prize to show for it.
In the movie Paradise Road, Dr. Verstak (Frances McDormand) practices medicine on the inmates of the prison camp, making her non-expendable. Near the end of the movie, she admits that she isn't an MD, but instead has a doctorate in philosophy. Though her husband is an MD, so she actually does have some basic medical knowledge.
City Slickers has a scene with two doctors needing to attend to an injured man because they're the only people in the group with first-aid training. The problem is that first-aid is all they can provide for him — he needs a surgeon, but they're dentists.
What're we going to do, give him a cleaning?!
In the movie 1776, Doctor Lyman Hall is taken aside by the seriously ill Caesar Rodney, who asks him a simple question:
Rodney: Sir may I ask of you, are you a Doctor of Medicine, or of Divinity?note A Doctor of Divinity is a degree in theology, that Christian clergy often have
Hall: Both, sir. Which one might be of use?
Rodney: The former most assuredly, then we shall see about the latter.
In Clue, Professor Plum, a psychiatrist, is called upon to determine what killed Mr. Boddy and immediately protests, "I am not a forensic expert!"
Inverted in The Santa Clause: When people refer to Neil as a doctor, Scott sarcastically replies "He's not a doctor, he's a psychiatrist." Psychiatrists actually are medical doctors, but most people seem to not know that.
In The Hangover, Stu is a dentist, a fact that everyone is quick to remind him of whenever he mentions his doctorate.
Much like the City Slickers example above, he would still have enough basic medical training to assist in an emergency.
Deep Blue Sea: This is outright said by the researcher responsible for the whole mess as she tries to tend to a shark attack victim.
Sherlock Holmes: Doctor Watson is that kind of doctor, if only to underline how much above even medical doctors Holmes is cognitively.
When faking an illness to lure out his would-be murderer, Holmes is forced to keep Watson at a distance by claiming risk of infection, but really because he's afraid Watson's medical knowledge would easily penetrate the disguise. Holmes's own medical insight is mostly limited to forensics, criminal and otherwise.
In Beneath The Surface by Gary Crew, Spiro introduces himself as 'Doctor Spiro Trotter' and has to clarify that he isn't a medical doctor in response to the hotel receptionist repeatedly telling him that nobody's been sick for years.
The protagonist of Youth in Sexual Ecstasy after acquiring an STD, looks for a doctor to get treated, he finds the card of a specialist in "sexual dysfunctions" (sex therapist) and goes to him to get treated, luckily for him the doctor already had a background on medicine and biology; The doctor later points out what his specialization really means.
In the third Spaceforce novel, Jez and Andri investigate a troubling accidental death and find that pretty much everyone involved, victim and suspects, is a doctor - but only two are 'that' kind of doctor.
Dr. Abraham Van Helsing in the original Dracula is that kind of doctor (and a professor of medicine), and not a vampire hunter, as adaptations often turn him into; he's just smart enough to know enough about them to improvise.
Live Action TV
Mohinder Suresh of Heroes has remarkable know-how in the medical arts despite being a geneticist.
He even mentions how he's not a medical doctor at least twice— once in Volume 1 when Thompson asks him to figure out what's wrong with Molly, and in Volume 4 when he's brought to see a bullet-riddled Daphne.
In the Stargate Verse: Dr. Janet Frasier, Dr. Carson Beckett, and Dr. Jennifer Keller are all That Kind Of Doctor. And don't forget Dr. Lam, even if the writers did.
Doctors McCoy, Crusher, Pulaski, Bashir, Placeholder, and Phlox are definitely that kind of doctor. To emphasize the Mildly Military nature of Starfleet, it is apparently not appropriate to address them by their rank (if any). Further, as a psychiatrist, Deanna Troi is likely a Doctor as well, sort of that kind.
Troi's title is Counselor, meaning she probably filled the role of a guidance counselor of sorts to the crew (more of a psychologist's job, and while they are doctors in the Ph.D. sense, her empathic nature helped her more than her training). Also, the official medical doctors all were required to learn multiple alien anatomies as well as forensics and other analysis. McCoy is pretty dependent on his lab in the original, but in space the doctors have to be able to cope with an emergency. After all, Klingon anatomy has double- or triple-redundancies to keep them fighting and Vulcans have their heart in their abdominal cavity, so why risk being underprepared?
All of these doctors (aside from Phlox, who's not an actual member of Starfleet, and Voyager's Doctor, who's a hologram) do have ranks, designated on their uniforms. McCoy was a Lt. Commander, for example. Troi, who does not wear a uniform, held the rank of Lt. Commander for most of the show and got a Hand Wave of not wanting to intimidate her clients because she out-ranked them. (Granted, what she was wearing instead was probably off-putting in other ways...) Crusher was a Commander. Bashir was a Lieutenant.
Even Voyager's Doctor eventually got a DLC turning him into the Emergency Command Hologram, temporarily replacing his medical database with a tactical one (and yes, he was able to use it effectively, employing a Shoot the Bullet tactic used once by a Romulan commander to disable two enemy ships).
In Mash, Hawkeye, Trapper, Frank, Henry, B.J., Charles, and Colonel Potter—pretty much all the male officers, not counting occasional visitors—were all that kind of doctor. Dr. Sidney Freedman is a psychiatrist, and therefore, is that kind of doctor, but it's not his occupation. In a crisis he's forced to help out in the O.R., over his protestations that "medical school was a long time ago."
The Doctor of Doctor Who has medical knowledge and has used it to heal people on occasion, but science is his forte and "Doctor" part of his assumed identity anyway. In "The Moonbase", he claims to have received a medical degree... under Lister on 19th century Earth. In any case, he's had centuries to come by plenty of knowledge honestly.
His being Not That Kind of Doctor is Lampshaded in "Utopia" when a guard tells Dr Yana that a doctor "of everything" had just arrived.
In the episode "A Good Man Goes to War", the character Lorna knows he must be a great warrior because "Why else would he be called that?" Turns out that in her language, "Doctor" means "Mighty Warrior". The irony is that the Doctor has become so feared in reputation, that he created the term. In a way, he is that kind of Doctor.
Liz Shaw is that kind of doctor, among other things. Harry Sullivan's doctorate is strictly medical.
In "The Ark in Space", the Doctor claims his Doctorate is purely honorary, and Harry (who's a naval surgeon) is "only qualified to work on sailors".
Martha Jones eventually became that sort of doctor. Her (temporary) fiancé Tom Milligan is also one.
The Doctor Who website has an entire page about the Doctor's qualifications.
In Torchwood, Doctor Owen Harper is that kind of doctor.
Dr. Sam Beckett from Quantum Leap straddles the line; while still amnesiac he recalls how to halt a premature labor, and then balks when Al tells him to do something requiring another degree; turns out medicine is just one of the six doctorates he holds.
The vets in All Creatures Great and Small sometimes have clients who mistake them for traditional doctors, often under embarrassing circumstances. Tristan once went on a house-call to an infertile couple under the mistaken belief that he was going to artificially inseminate their cow. Another time a woman turned up at the surgery asking for confirmation of her pregnancy and Siegfried pretended to comply with her wishes in order to freak out Tristan and James.
During one episode of ''Leverage" ("The Rashomon Job"), Sophie runs into Dr. Wes Abernathy. She asks what his PhD is in, and he announces that he is a surgeon.
Inverted in Season 17 of The Amazing Race when, after being U-Turned, Chad started taunting Nat at the Roadblock. Though really, it might have just been because Chad didn't know the difference between an MD and a PhD.
Chad: Nat you should be able to get this easy. How's that PhD helping you?
Nat (in a voice over): For the record, I have an MD, I do not have a PhD.
One episode of 3rd Rock from the Sun had Vicki asking Dr. Albright if she would deliver her (alien) baby. Mary tries to explain that she isn't that kind of doctor, she just has a doctorate in anthropology, but Vicki doesn't understand several of the words she uses and takes it as Mary just blowing her off because of the gap in their social classes, education, basic hygiene, etc...
"I'm an anthropologist." "Is that like, the butt?" Vicki confused both "anthro" or "anthropology" with "anterior", but also "anterior" with "posterior".
An episode of Sanctuary has Will and Abby kidnapped by a gang seeking medical aid for their boss, who was, of course, attacked by an abnormal. They go through about a half a minute of trying to convince said crooks that they are psychologists, which they are. It does not work.
Abby: Sigmund & Anna Freud, right here.
Also, Magnus, who isn't really a medical doctor though she certainly acts like one (along with every other kind of doctor.)
Will: So, you're a doctor of what, exactly?
Magnus: The specific discipline depends entirely on the patient...I specialize mainly in cryptozoology and xenobiology. Teratology, too, when the need arises. (mythical/extinct creatures, extraterrestrial life, and mutations, respectively)
Played with on Criminal Minds in Season Five, with Doctor Reid (who possesses three Ph.D.s but no medical training) after he was shot. Hotch makes him stay behind with Garcia, the team's analyst.
Hotch: You told me you were cleared to travel. You lied.
Reid: No, I didn't. I am a doctor, so technically it wasn't a lie.
Garcia: What was it, then?
Reid: Um...Second opinion.
Garcia: You're my bitch now.
The CSI Verse has two ex-doctors. CSI: Crime Scene Investigation had Dr. Ray Langston and CSI NY has Dr. Sheldon Hawkes. Both have ended up giving emergency care a time or two. Hawkes even helps with a bicycle first aid team in the park. Of course, the medical examiners (Robbins, Hammerbeck) are also doctors, but don't practice medicine.
Doc Robbins has occasionally been shown to do things medically related - while Grissom was losing his hearing, Doc Robbins gave him regular check-ups to make sure Grissom was attending to his health.
Lampshaded, played with and kicked to death in Top Gear, of all programmes. Jeremy revealed that he had obtained a cheaper quote for insurance because he called himself 'Doctor', rather than a journalist - the two pay vastly different rates of Car Insurance. He ignored the other two's protestations that HONORARY doctorates don't count.
Cliff on The Cosby Show is that kind of doctor (albeit a specialist, specifically an obstetrician). One rather hilarious scene in an episode was where Rudy hurt her leg, and cried to Cliff that she wanted to see a doctor. Cliff had to remind her that he was a doctor. Making it even funnier, when Clair came home and looked at it, she panicked a little and exclaimed that they had to call a doctor, again forgetting that Cliff, who was right next to her, was a doctor.
Jason Seaver from Growing Pains was a psychiatrist who, in early episodes, had to correct people when they thought he was a medical doctor and then defend being a "shrink". For instance, he was assisted a woman giving birth in public, letting her know he's a doctor. Her husband seems relieved by soon realizes that Jason plans to comfort her until paramedics arrive. The man then exclaims, "Oh, I thought you were a REAL doctor", much to his chagrin. This was befitting the attitudes of the early 80's in which psychiatry was not yet fully embraced by the public.
For a pathologist, Scully certainly does a lot of emergency/trauma type medicine on The X-Files. She even delivers a baby in one episode.
Subverted in an episode of Law & Order. As a doctor waits for her car in a parking lot, one of the attendants asks if she has any suggestions for his back pain. She quotes this trope, word for word, even though she is an MD, because her specialty is OB/GYN.
Despite his stethoscope and tongue depressors, it's safe to say Bally'sDr. Dude doesn't have a medical degree.
Dr. Zev Cohen from Mass Effect 1: "I am a doctor but not the doctor. My specialty is microbiology. Not first aid."
Mario truly did seem to be that kind of doctor in Doctor Mario, but it was probably non-canon.
Which is actually justified. When she wanted to be a doctor, she had her locket on, which acted as a damper for all of her senses, making her very clumsy. Presumably, if she had tried to be a doctor, bad things would have happened.
In Oglaf Naveen declares herself a doctor, despite having very little idea what a doctor is, her most obvious misunderstanding being the belief that a doctor's job is to solve mysteries, go on adventures, and get laid. Most people seem to buy it, even though her cure for everything is leeching above all, sex, and draining blood so she can drink it.
In Kim Possible, both of Kim's parents have doctorates. Her Mother's is indeed an M.D. (she's a brain surgeon), but her father's isn't (he's a rocket scientist). This results in visitors (at least Ron Stoppable) usually addressing them as Mr. Dr. P and Mrs. Dr. P, respectively. To not call them doctor would be disrespectful, but to just call them doctor would be confusing.
The old joke about people with doctorate degrees. "So you're a doctor?" "Yes, but not the kind that will do you any good."
Alternately: "Not the kind with any money."
Another old joke: An attractive woman ricks her ankle while aboard a cruise ship, and the announcement goes out: "Is there a doctor on board?". A Doctor of Philosophy rushes to her cabin, only to find that a Doctor of Divinity has beaten him to it.
An example of a non-medical doctor treating people successfully. Louis Pasteur was a doctor of chemistry, not a physician. This became a problem when he was faced with the prospect of treating a 9-year old boy bitten by rabid dog with the rabies vaccine he had just developed since he would be guilty of practicing medicine without a license. He went ahead anyway, the boy got better, and Pasteur was hailed as a hero instead of being prosecuted.
Other kinds of doctors:
Dr Pepper ran an ad campaign where "Doctors" said the drink was good for you called "Trust Me, I'm a Doctor", said doctors included Dr Dre and Dr. Love
Anaflex had a recurring joke where people ask "if inflammation does not go away, does pain return?" to doctors in many varied circumstances. One of them was a graduated receiving his diploma, and interrupting the ceremony to answer the cell phone call. "Sorry, I'm a lawyer"
Naturally, Dr. Chronos from Yu-Gi-Oh! GX is not that kind of doctor, being an academic professor, but his is very insistent upon being referred to as Doctor Chronos. (Until the second season when he becomes chancellor; everyone calls him "doctor" then, but he prefers to be called "Chancellor".)
Doctor Doom dropped out of school after his Freak Lab Accident and then proceeded to learn magic and take over a country. He never actually finished his Doctorate. No one would argue that he doesn't deserve one, but he simply never finished the coursework. Ordering the University of Latveria to give him a degree (what the fanon suggests he did) doesn't count, even though the thesis defense would have been...interesting.
Lampshaded in Secret Wars: Volcana asks Doctor Octopus to tend to the severely wounded Molecule Man; Octopus replies that his doctorate is in nuclear physics, not medicine, but he'll see what he can do...
Conversely, every doctorate brings full knowledge of robotics, including the Entomology course (see Henry Pym).
Also appears in Ultimate Spiderman. Peter is injured in a fight and goes to Dr Connors for help. Although he isn't an MD, as he is quick to point out, he is persuaded to treat the wound anyway.
One-shot Justice League foe Dr Julian September is a physicist. He is not mistaken for a doctor of medicine, but an official who don't want to reapprove of his funding makes a quip about September fixing his jeep, since he works in quantum mechanics. Shortly after, Dr September's work first paid off, when the official was struck by lightning before he could sign the paper that would have stopped September's work.
Brother Voodoo (Dr. Jericho Drumm) is a psychologist. Some readers assumed when they saw him go by 'Doctor Voodoo' that the title had come along with the office of Sorcerer Supreme, which he inherited from Doctor Strange.
Dr. John Henry Irons, aka the third Steel, is an engineer. The issue comes up when he visits a hospital on whether it's appropriate to call him "Dr. Irons".
There are several Liberty's Kids fanfics where the author has mistaken Dr. Benjamin Franklin as a medical doctor. He had an honorary doctorate in law and science.
In the Bleach fanfic Project Tatterdemalion, we have Dr. Yoruichi Shihouin (ecologist), Dr. Masaki Shiba (biology), Dr. Isshin Shiba (might technically be a medical doctor, but hasn't worked on anything but mice in years, so comes down to biology), Dr. Tessai Tsukabishi (physics), and Dr. Kisuke Urahara (any number of things). All research scientists- although they do manage to create a fast-and-dirty vaccine against The Virus. No medical doctors in the original group (although they do have a nurse and a paramedic). In the sequel, when (medical) Dr. Retsu Unohana arrives to treat the nurse's injuries, Yoruichi introduces herself with her specialty, to keep things clear.
Subverted somewhat in the Indiana Jones movies. Indiana was freqently referred to as "Dr. Jones" (especially by the evil people) but no one ever accused him of being a medical doctor. (His doctorate was, naturally, in archaeology, as was the one held by his father.)
Dr. Cockroach from Monsters vs. Aliens. It is never made clear what his field is. What we do know is that his PhD was in dance!.
Dr. Charles B. Pierce from Boggy Creek 2: The Legend Continues is mistaken for a medical doctor when asked to treat the mountain man Crenshaw's captive baby Boggy Creek Creature. Turns out Dr. Pierce only has a doctorate in Boggy Creek Studies.
12 Monkeys: Kathryn Railly is a psychologist. While she does spend a majority of the movie providing therapy for Cole and is never mistaken for a medical doctor, there is one scene in which she removes a bullet from him and assures him that she is qualified to do so. "I am a doctor".
This might be a bit of Fridge Brilliance: The film is set in a psychiatric hospital, and the doctors there tend to be psychiatrists, rather than psychologists. Psychiatrists really are that kind of doctor, having been to medical school, and it's not too much of a stretch that Railly would know how to do simple surgery. (The fact that she removed the bullet at all is the writers'fault.)
At one point in The Wolverine, Logan is treated by a veterinarian student.
In Neal Stephenson's The Baroque Cycle, Gottfried Wilhelm Leibniz is often referred to as "the Doctor" (not thatDoctor, mind you). He's actually a doctor of law, though he's more well-known for his arithmetickal studies than his legal studies. In addition, Daniel Waterhouse, an Omnidisciplinary Scientist, is referred to as "Dr. Daniel Waterhouse" later in his life. Inverting the trope, physicians are always referred to as "physicians", never doctors; even surgeons were alternately called "chirurgeons" and "barber-surgeons", never "doctors". Indeed, Dr. Waterhouse himself expresses strong contempt for physicians, treating them as if they were snake-oil salesmen (and given the state of 17th/18th-century medicine, that's exactly what they were).
In Terry Pratchett's first Discworld novel The Colour of Magic, there's a moment where we get a glimpse of an alternate universe where Twoflower and Rincewind are travelling on a plane, when "Zweiblumen" collapses. Someone asks "Rjinswand" to help since he's a Doctor, but Rjinswand points out that he would only be any help if Zweiblumen was some sort of nuclear reactor.
A scene in one of the Adrian Mole books has Pandora jumping into a taxi with the words "I'm a doctor and this is an emergency!" She doesn't mention she's a doctor of philosophy.
In Tom Clancy's Patriot Games, Jack Ryan gets annoyed at the fact that people are referring to his wife Caroline (who is a medical doctor, specifically an ophthalmic surgeon) as "Doctor Ryan", but are calling him "Mister Ryan". He points out several times to various people that, "I'm also Doctor Ryan". The problem is, he's a patient in a hospital at the time, his doctorate is in history, and the people who he is making these protests to are other medical doctors. Thus no one listens to him.
The Dave Barry column "Why We Don't Read" had one Dr. Belinda A. Burgeon-Wainscot, a teacher, speaking on behalf of the American Association of People Who Use the Title "Doctor" Even Though They Are Not Physicians, but Merely Graduate School Graduates, Which Are as Common These Days as Milkweed Pollen (AAPWUTDETTANPBMGSGWAACTDAMP).
Live Action TV
Parodied regularly in The Colbert Report: after getting his Doctorate of Fine Arts from Knox College, Stephen immediately started assuming that he could perform operations. He even started a recurring segment called "Cheating Death, with Dr. Stephen T Colbert, DFA".
Being a doctor of fine arts, he's only qualified to do operations on paintings.
In the Stargate Verse: This comes up a few times, but Dr. Daniel Jackson (PhDs Archaeology, Anthropology, and Linguistics) of Stargate SG-1 is the best example, while his equivalent in Stargate Atlantis is Dr. Rodney McKay (PhDs in Physics and Mechanical Engineering; he has noted his disdain for medicine, despite becoming best friends with one medical doctor and falling in love with another). Other examples include Dr. Bill Lee, a consulting scientist for the program (it is never entirely clear what his degree is in, but it's definitely not in medicine. He usually helps with whatever scientific crisis is most at hand during that episode.)
A weaker example is Samantha Carter, who holds a PhD in Astrophysics and realistically could go by Dr. Carter, but due to the greater emphasis on her military role she goes by her rank instead. However, in early episodes she is occasionally called Captain Doctor. (During her introductory scene, she specifically points out to her superior Colonel Jack O'Neill that she should be referred to by her rank of Captain rather than by her salutation of Doctor. She later proceeds to introduce herself to Dr. Jackson as "Doctor", to which O'Neill quips, "I thought you wanted to be called 'Captain'.")
This is played for laughs in one episode. A man who has captured SG-1 was injured, and asks Daniel to patch him up. Daniel explains that he doesn't know how.
Sam ends up patching him up with a first-aid kit due to her field medical experience, despite the fact that she's Not That Kind of Doctor either. She just learned it through military training.
Though normally this doesn't come up for Sam, it does occur when an alternate-timeline version of her introduces herself to the alternate version of Daniel.
Daniel Jackson (offering his hand for her to shake): Doctor Daniel Jackson. Samantha Carter(shaking his hand): Doctor Samantha Carter. Daniel Jackson: Oh! Uh, PhD. Samantha Carter: Oh, me too.
In "Harmony", a girl believes that Rodney should know something about, well, being a doctor. His response is similar to Daniel's above.
This come up again in Rodney's panicked rant in season 5 about why he can't deliver a baby. Note that this didn't prevent Daniel from delivering a baby on two separate occasions — three if you count one mentioned off-screen. He was much more calm about it.
In the first birth Sam was also looked to for help, but this could also have been because she's a woman and in that case would not necessarily be an example of this trope.
A (Subverted?) example in Atlantis season 5 when Daniel is kidnapped by a new Big Bad and apparently assumed to be a physicist since he was doing research in an Ancient physics lab. (He was actually there studying the files and history.) His response in this case is that he is Not That Kind of Doctor. Fortunately, Rodney was captured with him and actually is a physicist, so they are able to solve the problem.
Dr. Ross Geller of Friends has that title on the basis of a PhD in paleontology.
One time, when the gang was at a hospital:
Ross: I'm Doctor Ross Geller.
Rachel: Ross, stop it. That actually means something here.
In "The One with Russ," Russ, a periodontist, claims that Ross is jealous because he (Russ) is a real doctor.
Ross: You're a doctor of gums. That's the smallest body part you can major in. It's like, "Day one: Floss. Day two: Here's your diploma!"
Dr. Temperance 'Bones' Brennan of Bones is an anthropologist, and she is quick to correct anyone who refers to her as anything but Dr. Brennan.
Though her boss, Dr. Camille 'Cam' Saroyan, is a forensic pathologist—and, thus, is that kind of doctor. (Though that isn't her day job.)
In one episode, when Brennan is introduced as Doctor Brennan to a physician, he immediately asks "M.D.?", to which she replies "Ph.D". The physician then makes a snide remark about academics, which is rather galling considering an academic doctorate is often harder, and almost always requires more time to obtain than a medical one.
In addition, physicians couldn't even become physicians without Ph.D-holding professors (Biology, Chemistry, and/or Physics knowledge needed for MCATs/Med school)
Dr. Mary Albright from 3rd Rock from the Sun has a PhD. in Anthropology, but Viki Dubchek, the white trash woman who's the daughter of the Solomon's landlady and Harry's on-and-off GF, thinks she's a medical doctor. The gag actually carries to the point where Viki asks Mary to deliver her baby, and ignores Mary's outright statements of "I'm Not That Kind Of Doctor", believing that Mary doesn't want to do it because she doesn't have medical insurance.
CSI: Crime Scene Investigation: Dr. Gil Grissom is a PhD not an MD as he is quick to remind someone who asks him how to treat an animal bite. Although, as an entomologist, he's pretty good with bug bites.
There was an episode of Lost in Space when aliens mistook Dr Smith for a medical doctor, despite his protests otherwise. Of course, he was originally a medical doctor, but then the writers just changed him to a Morally Ambiguous Doctorate.
Used in, of all places, Growing Pains where Dr. Seaver has to help a young girl during her Born in an Elevator moment. When she hears his title he admits that he is a Psychiatrist, not a Medical Doctor, but assures her that he is still trained in basic medicine.
Aversion: Dr. Frasier Crane and his brother Niles are both That Kind Of Doctor, despite frequently (and amusingly) being mistaken for Not. Possibly a borderline case since psychiatrists (MDs who complete residencies and board certification in mental illness) are commonly conflated with non-MD-holding mental health professionals such as psychologists and social workers.
It doesn't help that Frasier and Niles are usually seen helping people with personal drama, bad habits, and relationship issues, which is, usually, a councilor or social worker's job. Frasier uses his Ivy-league education to feed his minor celebrity status while Niles seems to care more about maintaining his lifestyle and social status. The joke may be that no one takes psychiatry seriously, or that nobody takes them seriously because they're more concerned with money and reputation than helping people with serious mental illness.
Reid: (poking at a mutilated corpse with excited interest) Did you know that originally birthday candles were intended to protect the cake's recipients from evil spirits, so much so that the Church condemned birthday celebrations as a pagan ritual?
Cop: (after a long pause) What kind of doctor did you say you were?
In The West Wing, Josiah Bartlet is a Doctor of Economics. Of course, he also has another title he prefers to be addressed by throughout the series. It does, however, give him a minor moment of awesome when the Chief Justice of the Supreme Court — not a fan of his — snidely refers to him as "Mr. Bartlet."
His wife, Abby, is That Kind Of Doctor. However, she loses her license to practice throughout the remainder of his term once her role in his keeping his multiple sclerosis from the American people was revealed.
Shows up in one episode, where President Bartlet tears a conservative radio personality to shreds. At the beginning of their conversation, he asks her what exactly her doctorate is in (it's English literature). More to the point, he initially asks her if she is an M.D., forcing her to clarify that she is not.
Mad Men: Dr Faye Miller is not that kind of doctor, but her father has a heart condition so she knows the symptoms.
Also, Bobby doesn't understand this trope when Megan's father, a professor, comes to visit; Don explains it to him.
The Big Bang Theory has most of the main and recurring characters have Doctorates in physics, with others in microbiology and neurobiology. The character Howard has a Masters in Engineering, which leads to plenty of jokes at his expense for not being a doctor. Of course there are a few occasions where people mistake their title as being medical doctors: "A doctor doctor or your kind of doctor?"
In one episode, Sheldon gives Leonard medical advice in his usual Insufferable Genius manner. Leonard sarcastically responds, "Thank you, Doctor Cooper." As usual, Sheldon doesn't get it and confusedly replies "You're welcome, Doctor Hofstadter." In another episode, someone (a police officer) who just learned Sheldon is a doctor is reassured by Leonard with "Don't worry, not the kind with access to drugs."
In addition to the title character, River is a doctor (and, someday, Professor) of archaeology.
Rory:(after watching her curb-stomp homicidal aliens) So...what kind of doctor are you?
River: Archaeology. (shoots the last one standing without looking) Love a tomb.
Clifford Jones in "The Green Death":
Evans: What killed him? You're a doctor, Dr Jones.
Cliff: I'm not, you know. I'm a biologist.
Tommy Oliver picked up a doctorate in palaeontology at some point between Turbo and Dino Thunder. Parodied a couple of seasons later.
Kira: Doctor O. would have loved to see that.
Adam: You know, I still can't believe he's a doctor.
When Becker, a 'real' doctor, meets a psychologist played by Rhea Perlman, he doesn't even try to hide his contempt and addresses her as "Dr." only in air-quotes.
Overplayed on many soap operas, which will find their doctor characters capable of delivering babies, performing surgeries, performing autopsies, treating children, all in one fell swoop. The only soap to avert this, appropriately enough, was General Hospital, which limited their doctors to one specialty.
In Doonesbury, Alex goes into labor while at a graduation ceremony surrounded by PhDs; those around her naturally start shouting for the help of a real doctor.
It's unclear what type of degree Dr. Dude has, but whatever it is must be ahhh-some!
During his rapper gimmick, John Cena used the Red Baron "The Doctor of Thugenomics." This has inspired some female online fans to call themselves "the Nurse of Thuganomics."
WWE star Xavier Woods is known as Xavier Woods PHD on Twitter, with the wrestler who plays him holding a degree in psychology
In Cabin Pressure, a passenger gets a heart attack on an airplane. Whilst trying to decide whether to divert or not, the pilots notice there's a doctor on board and start requesting ever more urgently that any person with medical training come to the flight deck. As no one comes, they start speaking of a "hypothetical doctor" with a hypothetical sandy moustache hypothetically sitting in the seventh row. As the man eventually comes, he advises a bridge, because a tunnel's out of the question...and really his Ph.D.'s in engineering.
Dan Coffey hosts a show called Ask Dr. Science, justifying it because, although "not a real doctor," he "has a Masters Degree ... in Science!"
In the main Mega Man timeline (and nearly all fan works), being a "Doctor" doesn't invariably mean you're a medical doctor...instead, it invariably means you build robots. ::sigh::
Notably, it means you build robots even if you have a doctorate in something else. Dr. Cain, for instance, has a background in archaeology and botany, and still invented reploids.
Dr. Loboto from Psychonauts, as quoted above. Of course, not knowing jack about brain surgery doesn't necessarily stop him from performing it...
He is a dentist, however. Whether or not he actually has a degree is debatable.
Half-Life: Dr. Gordon Freeman, though he has yet to be mistaken for a medical doctor.
Oddly enough, he has been mistaken for a physicist somehow.
Possibly justified as anyone who can routinely and effectively utilize a standard medical kit to treat radiation burns, poisonous bug bites, extraterrestrial bug bites, broken bones, BULLET WOUNDS, and a mild cough would probably require at least an M.D.
Or a full-body ultra-high-tech powered armor with an AI (HEV), which performs medical operations by itself.
One of these creates an odd inversion of Not That Kind Of Doctor. During the suicide mission, Mordin is a candidate for the Tech Specialist position. Try to use him in that regard, however, and he's guaranteed to die.I'm a doctor, not a hacker.
In "From Ashes", one squadmate asks Liara if she's ever dug up a dinosaur. She starts explaining the difference between archaeology and paleontology - before realizing that they're joking (except James, who just likes dinosaurs).
It was revealed in Poker Night at the Inventory that The Heavy has a doctorate in Russian Literature. When asked how much use he could possibly get out of it when his job is mowing down people with a minigun, he replied, "More than you'd think."
The Engineer has eleven "hard science" doctorates.
Schlock Mercenary toys with this when they land on an uncharted planet. After Tagon gets unexpectedly eaten by a sea-going predator (which he shoots his way out of) he calls in Kevyn and Bunnigus for professional opinions. Kevyn is an engineer. Bunnigus is a medic. They wind up calling in the chef instead.
Sad Panda: I just said that I watch Doctor Who a lot.
Nostalgia Critic: Close enough.
Doctor Alexander Steubbing, a professor of biochemistry who is better known as "Lifeline", one of the heroes of the Global Guardians PBEM Universe, has encountered problems with this trope. He doesn't really keep a secret identity, and his real name and occupation well known enough by the general public that he's called "Dr. Steubbing" in the press just as often as he's referred to by his "superhero name". The problems arise due to his superpowers: he can heal injuries, cure diseases, and regenerate tissue at a touch (he can even raise the dead, assuming they haven't been dead for longer than a couple of hours or so, but he doesn't advertise that fact). This has led to people hearing him called "Dr. Steubbing" and assuming that he is that kind of doctor...
Rebecca: Are you one of the doctors that takes care of people that are dying?
Dr. Mother: Not one that works in this hospital. I’m more of a researcher and scholar than anything else. And I came to make you an offer
Accuser: In the first episode, after a jury acquits Barry Dinsmore, he congratulates Dan Mason for the good work he did defending him. When that line was translated for Brazilian audiences, Cultural Translation changed it so Mason would be called a "doctor" instead of a "counselor".
Dr. Venture from The Venture Bros. is usually called "Doctor Venture", even though he dropped out of school after his father died.
Dr. Orpheus (whose official credentials are a major in Communication with a minor in Women's Studies from a community college yet claims to have received his doctorate from "a higher power") is the only character to always call Dr. Venture "Mr. Venture." The causes and implications of this are unknown.
The only character known for certain to have a real doctorate is Jonas Jr., who earned two of them only a few months after escaping from Dr. Venture's bowels.
It's been implied that Billy may be an actual doctorate and possibly even That Kind of Doctor; he mentions that he is a "neurogeneticist" and while he admits that this is not an area with much hands-on applicability, he's still apparently the gang's go-to guy for medical help and we've seen him perform surgery several times.
He doesn't legally have a doctorate until Season 4, where he gets a forged one via Monstroso's connections.
After The Monarch has a severe allergic reaction to a gourmet meal, his wife Dr. Mrs. The Monarch tells him she can't help, as she's not a doctor. When he asks why he called her Dr. Girlfriend during the years when they dated, she clarifies that she's "not that kind of doctor", although it's not clear what kind of doctor she might be.
She mentions she's a physicist in a fourth season episode when tracking Captain Sunshine.
Family Guy: When the Griffin family starts working with Dr. Diddy at his record label, Chris asks Diddy if he could perform surgery on himself in the event he got shot. Whereupon Dr. Diddy calmly replies that his doctorate is in optometry.
In Booster Gold's episode of Justice League Unlimited, he comes across a woman giving birth and tries to pass responsibility to Doctor Simmons, who informs him that she's a physicist.
Doctor Octopus' doctorate is not in medicine in Spider-Man: The Animated Series either, but he is able to bluff Aunt May into thinking he is one in one episode. Short version: When he and some other super-villains woking for The Kingpin are looking for Spidey, the Scorpion gets the idea to question Peter, due to the photographs he takes - Ock insists on going to his house himself to avoid any unnecessary violence. When he introduces himself to May as Doctor Otto Octavius, May panics when she hears the word "doctor" and thinks Peter has been injured. Ock is able to think fast and tell her that Peter collapsed on the street and was taken to his clinic, volunteering to take her there. (The clinic is actually owned by the Kingpin, and Ock is thus able to leave a ransom note for Peter making it seem like May has been kidnapped, demanding he send Spider-Man there.
There was a related exchange in an episode of the old animated Ghostbusters cartoon between The Chick and the Plucky Comic Relief on an episode with weird weather. "Besides, we're not meteorologists. We are scientists." "A meteorologist is a scientist."
In Futurama, amazingly Doctor Zoidberg, who has declared people dead when they have been sitting up and talking, and diagnosed robots with fin-rot, DOES have a doctorate. It is a doctorate in Art History. A reversal in that it's only Zoidberg himself who doesn't seem to realize that this doesn't qualify him to be a medical doctor.
An episode from the Un-Cancelled season reveals that Zoidberg is in fact That Kind Of Doctor... but his field of medical study is xenobiology, meaning that while he's a brilliant surgeon when it comes to all sorts of alien races, he doesn't know squat about human beings. It also reveals that Professor Farnsworth keeps him around in spite of this because they're True Companions.
Dr. Krieger "Not even the other kind, technically."
Inverted in Beware the Batman, when Alfred has to inform a scientist smitten with Tatsu that he's not, in fact, a medical doctor. He remains undaunted in giving her aid, despite the obvious fact that his help is neither wanted or actually useful.
Dr. Burr: Give me room, I'm a doctor! Alfred: Wait! Are you a medical doctor? Dr. Burr: I am tonight.
Jay Sherman of The Critic has a doctorate in film.
Atlantis: The Lost Empire: Kida had some trouble grasping the notion that not all doctors are medics. Milo, for example, is a doctor in linguistics.
My Dad The Rock Star: When Rock Zilla's alma mater granted him a honorary doctorate, he thought he'd be that kind of doctor and started practicing the shout of "Calling Doctor Zilla". When he was told it wasn't that kind of doctorate and he'd instead be a sort of professor, he shouted "Calling Professor Zilla".
Hitler's Propaganda Minister Joseph Goebbels demanded that everyone would call him "Doctor Goebbels". His doctorate? Literature.
The demand is not that unusual in Germany, where titles are given much more respect than North America. Also, physicians in general are typically referred to as "Arzt (pl. Ärzte)" instead of "Doktor", so the title doesn't quite have the same connotations as in English. "Doktor" is still used in less formal situations and when directly addressing one, e.g. "Ja Herr Doktor, aber was macht Zataproximetacine eigentlich?
Perhaps the most notorious Nazi "doctor," Josef Mengele, had a PhD in anthropology from the University of Munich and was an assistant at the Institute for Hereditary Biology and Racial Hygiene in Frankfurt. He got Drunk with Power when assigned to Auschwitz, where he performed gruesome human experimentation, particularly concerning twins and usually without anesthetics, that produced no viable scientific results, or indeed any results beyond satisfying his morbid curiosities.
People with two doctorates may demand to be addressed as Doctor Doctor X (although it's kind of cumbersome and no one actually ever does so). People with a professorate and a separate doctorate generally will be addressed as Professor Doctor, though not usually in everyday conversation.
On the other hand, some teachers with a doctorate or professor's degree at some universities and schools don't insist on being called "Professor/Dr. (name)", and even discourage it in many cases. At many other colleges and universities, however, "Doctor So-and-so" or "Professor So-and-so" is the established way for a student to address their doctorate-holding instructor, and to do otherwise would come across as, at worst, very rude.
Uwe Boll also has a doctorate in literature. Good luck finding an unironic mention of him as "Doctor Boll", though.
Doctoral students everywhere. After going through the very long, sometimes soul-sucking process of actually getting that PhD, you damn well want some acknowledgment for it. And yet the public insists on thinking that all doctors are physicians.
The radio talk therapist Dr. Laura Schlessinger is a doctor of physiology, not psychiatry. Not false advertising exactly (she's perfectly entitled to put Dr. before her name), but misleading.
Aversion: Every university graduate in Italy is referred to as "Dottore" or "Dottoressa." Unless, that is, they have some more prestigious title, such as "Avvocato" (lawyer) or even better, "Ingegnere" (engineer.)
It's so pervasive that many people will tend to automatically address as "dottore" someone who seems to be of high status. Also, even some non-graduates may be addressed by a title if their profession commands respect: the most common example is "Geometra" (a skilled construction technician, who has authority to approve some civil engineering projects).
Similarly, in Egypt, people with degrees may be called "Ustaz" ("professor") or "Doktor" in informal settings, even if they aren't professors or have doctorates. Also played straight, because in Egypt, medicine is a seven-year bachelor's degree, and not a doctorate, but people colloqually call physicians without advanced degrees "Doktor" all the same—and are more likely to do so than with, say, someone who holds a bachelor's in something like literature or psychology.
Also: An actual engineer won't be called "Mohandis" ("engineer"), since that's the title for certain kinds of skilled worker (well, "Bash Mohandis," i.e. "Chief Engineer" is), like electricians.
Dr. Phil is not a medical doctor, but has a doctorate in psychology.
He also has no license to practice, having officially retired in 2006. Apparently his TV show counts as "entertainment" rather than "psychology", so it's not against the law for him to continue hosting it.
The degree handed out by Law Schools is called a Juris Doctor, and yet no one ever refers to lawyers as "Doctor".
Only some law schools give out JD, others hand out Bachelor of Law or Master of Law. All are generally considered the same thing except in name. It is also possible in some places to become a lawyer without having attended law school.
All U.S. law schools award the J.D. as the first professional degree in law, while the Master of Law (LL.M.) is an advanced degree in certain specialized areas of law (most commonly taxation). Law schools in other common law jurisdictions (e.g., the UK, Canada, Australia) award the Bachelor of Law (LL.B.) as the first professional degree. In the UK at least, it is possible to get an LL.M. one year after completing the LL.B. and before (or even without) attending law school itself.
Of course, this is very specific to the respective jurisdictions. In others, the legal system may be completely different. For example, in the german-speaking part of Europe (Germany, Austria and Switzerland), there is no law school as in the U.S., but legal studies are a "normal" course of studies at university: first you get a Bachelor of Arts degree, afterwards a Master of Arts degree. Then you may or may not become a doctorate student, which will give you simply a PhD in Law; the important part is taking the Advocate exam (which you can do as soon as you have a MA degree). If you pass the exam, you get the title "RA" or "Rechtsanwalt" (literally "Lawyer"), so it is common for lawyers to use two titles: "RA Dr. Mc Cool Name" - which would translate roughly to "G. Mc Cool Name, PhD, JD".
In Crossing Jordan, when Dr. Jack Slocum takes over, his office door reads "Jack Slocum MD, PhD, JD". So he's all three kinds of doctor!
One imagines that he has an uncomfortable time at medical and legal conventions, given the lawyer jokes and doctor jokes that tend to fly at such events.
Madalyn Murray O'Hair actually was commonly referred to as "Dr. O'Hair" in American Atheist publications, though technically she earned a L.L.B which was later converted when all first professional law degrees in the US were automatically changed to JDs. (However, her school wasn't ABA approved so she couldn't sit for the bar exam.) Though in an inversion, she most likely was hoping to be mistaken for "not that kind of doctor", because despite her public legal battles earlier in her life, her articles by this point tended to delve into history, and obviously a Ph.D., especially if it was assumed to be in some kind of study of history as would be assumed for a doctor writing papers on history without mentioning otherwise, would add far more credibility to her many less than mainstream views (and because, as previously mentioned, no lawyer without a M.D. or Ph.D. refers to themselves as a doctor in the first place, so gaining legal credibility wouldn't make sense unless she hoped to be mistaken for a Doctor of Juridical Science, who do refer to themselves as "doctor").
Nutritionist Gillian McKeith, who "voluntarily" stopped calling herself Dr. Gillian McKeith on the grounds she wasn't a medical doctor, just before the Advertising Standards Authority insisted that she stop calling herself that because the college she got her PhD from was "not accredited by any recognised educational authority".
In other words, not only is she Not That Kind Of Doctor, she's not actually any kind of doctor.
According to the book Bad Science, that was in fact the Advertising Standards Authority's actual take on the situation. The part about the specific concern that people would mistake her for a health professional (that kind of doctor, to be specific) was just her own spin she gave when she was explaining her decision to stop using the title. For the ASA adjudication, the criticism was that people would assume that her advice was coming from the someone holding the position of a recognized Ph.D. or M.D. (The giveaway here is that she called herself a "nutritionist"—an actual medical doctor specialising in nutrition and diet is a dietician, and a Ph.D. with a similar focus would probably call themselves a "nutrition scientist".)
The author of Bad Science, Ben Goldacre, still invariably refers to her as "Dr. Gillian McKeith, Ph. D; or to give her her full medical title - Gillian McKeith".
Dr. Susan Block, best known for her sex advice, got her graduate and post-graduate degrees in philosophy, though "with an emphasis in psychology" and her undergraduate degree was in theater studies.
Having grown up the child of a university administrator, this anon would like to point out that it's fairly common for this to come into play among staff members. Doctorates in business, literature, engineering and history are formally addressed in pretty much the same way, especially with letters and public addresses, as a sign of respect.
Theodor Geisel, AKA "Dr. Seuss", isn't a doctor at all; the "Dr." is merely a pen name.
As did that of the Duke of Wellington who was similarly honoured the same day, June 14, 1814. Blücher at the time joked that if they made him an honorary doctor they should also make Gneisenau, his chief of staff, an honorary apothecary. He and Gneisenau got honorary doctorates (in philosophy) from Berlin University later that year.
Dr. Dre did not attend any university. He does have an honorary degree in Street Knowledge, though.
"Dr. Dre can suck my dick, that bitch got no PHD.
I lost track of mine, I got stupid whack degrees."
— MC Hawking, "The Mighty Stephen Hawking"
Despite his claims to the contrary, creationist Kent "Dr. Dino" Hovind does not hold a valid doctorate. He bought his "degree" from a non-accredited "university" where he quite literally didn't do the research.
See for yourself. His "dissertation" is online here. The first sentence is "Hello, my name is Kent Hovind," so it's obviously not written in formal academic style. He plagiarizeshimself at one point.
Dr Pepper and its knockoffs (of course)
Sir Doctor Stephen Colbert, DFA. Doctorate of Fine Arts, an honorary degree or one given to a graduate student of the highest caliber. It means he has made a contribution to the field, and human knowledge.
Dr. Karl Sven Woytek Sas Konkovitch Matthew Kruszelnicki (usually called Dr. Karl), Ig Nobel Laureate and science guy, has not done a PhD. He has a lot of degrees, but he's "Dr." because of a Bachelor of Medicine and Surgery.
Dr. Hunter S. Thompson received an honorary doctorate from the Universal Life Church in the late sixties. Not sure what for, but he liked calling himself a "doctor of journalism" and having people referring to him as such.
Several nurses have doctorates in nursing, which entitles them to be called "doctor." This causes some friction with physicians.
Dr. Lewis Yablonski is a sociologist who in 1967 visited several hippie communes and residences to gather information for a book (later titled The Hippie Trip). When he went to Morningstar in Northern California, he said "I'm Dr. Yablonski, they're expecting me" and the man who greeted him immediately turned around and called out "The doctor's here! Is anyone sick?"
According to AP style, the Dr. honorific is only supposed to be used for actual medical doctors.
It is also used for paramedical professions and, for some bizarre reason, members of the clergy with earned or honorary doctorates. Ironically, AP style specifically does not use it in the majority of situations where someone actually earns a doctorate.
DD, or Doctor of Divinity, is an accepted higher degree in theology and religious studies and is carried with pride by ministers and priests of all Christian denominations. The convention in Britain is that the two titles are used together to prevent misunderstanding - ie, conflated as Reverend Doctor. There is a case of a medical doctor who after some years followed a vocation to become a priest, eventually adding the suffix DD to his MD. He became a very rare Reverend Doctor Doctor....
Notorious Irish Presbyterian minister and politican, the Reverend Doctor Ian Kyle Paisley M.P., got his doctorate from a degree mill in the Bible Belt of the USA, and as people have pointed out, is not eligible to use the title "Doctor" as it came from an unrecognised institution. This makes him the Gillian McKeith of religion and politics.
Derek Smart, the man behind Battlecruiser 3000AD and Universal Combat claims to possess a doctorate and frequently titles himself as Ph.D. However, his thesis is not listed anywhere and he has refused to divulge basic details about his doctorate, such as which college he attended or who was his supervisor. There's understandable suspicion that he's lying.
Former porn star Sharon Mitchell used her savings from nearly thirty years in the business to put herself through college and get a doctorate. Laudably, she had recognised that people working in the porn industry are at higher risk of contracting diseases, and that one performer with an STD who carries on working and doesn't declare it can infect a MASSIVE number of people.She also knew that younger porn performers are likely to be very ignorant of the risks and implications of the business, and that their employers can profit by keeping them ignorant. So she set up the Sharon Mitchell Foundation as a means of bringing practical advice, sexual education and practical, affordable (or free) medical treatment for people working in the sex industry. All very laudable, and a lot of people were impressed enough by Doctor Mitchell's personal achievement to donate generously to the charitable foundation. But... everyone meeting an engaging, personable and likeable woman with a lot of drive and energy to do good, simply assumed she'd trained as a medical doctor at an accredited college. Sharon never contradicted this impression. A lot of dissillusionment set in when it was discovered her doctorate was in social services and it was from a college which, while not exactly a degree mill, wasn't all that prestigious either. The Sharon Mitchell Foundation is now bankrupt and Sharon herself has returned to the business as a "mature performer".
Rachel Maddow has a doctorate in politics from Oxford. Interestingly, she only occasionally mentions the fact, despite hosting a show dedicated to the subject she has her doctorate in! Which means that all those articles calling her "Ms Maddow" should in fact be calling her "Dr Maddow"...
Chef Erin Burke, one of the founders of the Floribbean Cuisine movement in the 1970s, has two PhDs to her name: one in history, the other in biology, and indeed she worked as a college professor for a time. She also has a Bachelor's Degree in Culinary Arts, and these days prefers to be called "Chef" rather than "Doctor".
Bill Cosby has Honorary Doctorates from over a dozen universities, most of them in Humane Letters, but he never uses a title.
He also has a real doctorate in education from University of Massachusetts, Amherst. He is listed as William Cosby, Ed. D. in the end credits to several of his shows, including The Cosby Show.
