This is a Lexicon entry: the mechanism, when it shows up, and the countermeasure. The full correction, with real-world cases and the audit prompt, hasn't been written yet.
When it shows up
Advertising (funny ads are recalled at higher rates). Education (humorous examples stick while dry ones fade). Social media (humorous framing drives sharing and retention). The effect applies to both intentional and incidental learning contexts.
Failure mode
Overweighting humorous information in decision-making because it is more available in memory. The funny anecdote crowds out the dry statistic. Persuaders exploit this: wrap a weak argument in a good joke and it bypasses analytical scrutiny.
Countermeasure
Recognise when humor is enhancing memorability without enhancing validity. Ask: "Would this argument be persuasive if it weren't funny?" Separate the entertainment value from the informational value.
