'''Basic Trope''': Belief makes it real.
* '''Straight''': Alice and Bob's belief in something makes it real or allows it to happen.
* '''Exaggerated''': Alice and Bob are cornered by a threat that isn't normally found in the real world. They renounce their belief in said threat, [[PuffOfLogic causing it to immediately vanish]].
* '''Downplayed''': Alice and Bob pray when they're in a tight spot. Something happens, [[MaybeMagicMaybeMundane seemingly by coincidence]], that helps them out.
* '''Justified''':
** Alice and Bob are wizards, belief in magic is what gives them power. When they stop believing? Then they lose their powers.
** The world is created by the minds of people. If they believe something, then it will happen because it's constructed by their thoughts.
* '''Inverted''':
** Anything Alice and Bob have a strong belief in ceases to be true.
** ''Denial'' makes it "un"-real. Charles suffers from a serious terminal illness that by all means ''should'' have killed him long ago, but because he staunchly refuses to acknowledge or even entertain the idea that he might be sick for just a second, he is still alive and even relatively healthy.
* '''Subverted''': Alice thinks her belief in magic is what allows her to cast spells, but it turns out Carol the rational materialist can cast spells too, even though she doesn't believe in magic at all.
* '''Double Subverted''': It turns out Carol believes in [[ClarkesThirdLaw sufficiently advanced science]] and she believes she's only "hacking space-time" which allows her to do spell-like effects.
* '''Parodied''': "I believe I will have a cone of ice cream soon... HUZZAH! there it is!"
* '''Zig-Zagged''': Sometimes belief conjures things and sometimes it doesn't. Sometimes it behaves like MagicAIsMagicA and other times like WildMagic.
* '''Averted''': It doesn't make a difference whether they believe in it or not.
* '''Enforced''': A Christian fantasy book line editor insists that authors portray belief in the Christian God as the source of the hero's prayer powers.
* '''Lampshaded''':
** "So, wait, your belief in fairies makes them real ex nihilo? Seriously?"
** "If you don't believe in the magic then it's not gonna work."
* '''Invoked''': TheHero needs a MidSeasonUpgrade, so [[GondorCallsForAid so he calls up every single friend of his and asks them to imagine one for him]].
* '''Exploited''':
** Emperor Evulz convinces the villagers to believe he's invincible, making him so.
** Belief in itself doesn't conjure anything, but it drives people enough to create reality based on the belief, thus making it real.
* '''Defied''': Carol refuses to believe such balderdash and comes up with rational explanations.
* '''Discussed''':
** "Tinker Bell needs your help - clap your hands if you believe in fairies!"
** "How come if we believe in something, it comes true?"
* '''Conversed''':
** "Oh, not that clap your hands if you believe tripe again! It makes my hands hurt every time they use it in a play."
** "As you can see by this scene, believing in magic to gain magic is a metaphor for self-empowerment. In other words, confidence."
* '''Deconstructed''':
** Alice and Bob have to avoid monster movies and their commercials because thinking about them might summon them.
** Alice and Bob pray for something to happen, and it does. However, just because they got what they asked for doesn't mean they got what they [[BecarefulWhatYouWishFor wanted]].
** Alice and Bob rely completely on believing to fix a given problem, which looks like they're doing nothing at all. Thus, the problem is never fixed.
* '''Reconstructed''':
** Alice and Bob practice [[SummonMagic Belief Based Summon Magic]] and thus are {{The Beast Master}}s for {{Imaginary Friend}}s. Unconsciously thinking up something nasty is an occupational hazard they are trained to deal with.
** Because silent belief is closer to the essence of desire than spoken words, prayers are not misinterpreted, but the one praying might not realize that what arrived is what they truly want.
** Alice and Bob's first approach to a problem is believing in possible solutions, because believing that a solution exists is the first step to creating it in reality. In other words, it's a brainstorming session.
