- Accidental Innuendo: At one point, in discussing Bernard, Lenina and Fanny comment that he is "so small" (emphasis in original). Of course, in context, it is clear that they are discussing his short stature; however, to some readers, it can appear that they are talking about a different kind of size.
- False Dichotomy: Mustapha Mond's experiment on equality fails to be an argument against free will because the experiment seems to have been engineered to fail. The people involved in the experiment were Alphas. They not only had a high intelligence that made them efficient at intellectual work, they were conditioned all their prior life to be happy only with specific jobs. This ensured civil war, because they were literally brainwashed into being incapable of accepting the menial jobs they were shown. Yet no character points this out. If the experiment involved members of all castes, except without the caste system being enforced (allowing castes to interbreed, and take different jobs if they wanted to), or the citizens selected for the experiment were adults who were spared conditioning as children, the experiment could probably have succeeded. The "brilliant minds" who became disillusioned with society and were banished to the world's many islands to do as they please (alluded to at the book's end and explored in Huxley's Island) certainly created what could very well be a viable alternative to "civilization" (with its brainwashing and enforced caste system) and "savage" (poverty- and conflict-ridden) reservations. Thus the presented dilemma between pointless hedonism, civil war, and low-technology reservations, is a false one.
- Harsher in Hindsight
- Hilarious in Hindsight: The worship of Henry Ford looks even sillier given the direction of his namesake company and the U.S. car industry as a whole.
- Moral Event Horizon: The painful conditioning of Delta babies against books and flowers.
- Squick: In the casually promiscuous society in which the book takes place, it is considered healthy - even endearing - for young children to sexually experiment with each other. There is also a memorable passage pointing out the more Freudian aspects of breastfeeding, and the descriptions of John's mother.
- Values Resonance: One of the newer printings says this on the back cover.
- What Do You Mean, It's Not Didactic?: The novel might have been written as a Take That against the excesses of 1920s hedonism.
- The Woobie: Poor, poor John "The Savage". As if growing up bullied and ostracized by everyone was bad enough, he ends up despising the very world he thought would be his one salvation. And after being ostracized there too and paraded around like a circus animal, he chooses exile. After the curiosity seekers chase him even there, and after betraying his beliefs in a drug-induced stupor, he is finally Driven to Suicide.
- Arc Fatigue: The Enchanted Express arc went on for several hundred thousand words and over a year - and even the author eventually admitted that "the saga of the Excess Express" dragged on for longer than expected.
- Ending Fatigue: It's 2.4 million words long, with the end nowhere in sight.
- Fake Longevity: A curious, non-video game example. Yes, it's almost two and a half million words long, but a considerable amount of it can be skipped without any major loss of plot details. Transformation scenes abound, the overly long gags go on long enough that it makes Tarantulas sympathetic when he gets sick of hearing them, and several plots barely qualify for even tangential relevance. Chapter 66 shows this - it's 76,000 words of Nihilators dying, but with scarcely a mention of Team Aurabolt or Oblivion's Shadow.
- Hilarious in Hindsight: All of the events in Pokémon Mystery Dungeon occuring in one continuity instead of Alternate Universe? A crazy idea that only occurs in fanfics, I say!
- Kudzu Plot: To almost ludicrous levels. The story starts with Team Aurabolt and the quest for the seven Star Badges. Meanwhile, fifty chapters down the line, we see Caserin the Luvdisc, Mack Salmon, Bruce the Oztralian Sharpedo and some other characters of Nominal Importance searching for the Aqua-Monica.
- Moral Event Horizon: Well, where do you start for the Nihilator high command...
