Bizarreness Effect
Bizarre, unusual things are easier to remember than ordinary things.
The bizarreness effect refers to the tendency to remember bizarre material better than common material. The theory is that unusual content triggers deeper, more elaborative encoding — we have to process bizarre items more carefully because they don't fit our existing schemas. This is widely used in mnemonic systems and advertising, where a strange visual encodes the brand name more effectively than a literal one.

Recognising a definition is not the same skill as spotting it.
Two scenarios from the app, with distractors drawn from the same family of biases — which is what makes them hard.
A person recalls the bizarre text message autocorrect fail they sent to their boss more clearly than the hundreds of perfectly correct messages they have sent, because the embarrassing and unusual error creates a vivid memory that routine communication cannot match.
A student remembers a bizarre exam question about a singing dinosaur more clearly than the serious questions about core course concepts, because the unusual and unexpected nature of the question created a stronger memory trace than the conventional material.
