Humor Effect
Humorous information is remembered better than neutral information, making funny ideas feel stronger and more prevalent than they objectively deserve.
Forty marks, one distinct — your eye reached it first, and your memory will too.
Why the standout sticks
The humor effect operates through at least two mechanisms. First, humorous material receives increased attention at encoding due to its emotional arousal and incongruity resolution (Schmidt, 1994). Second, humorous material is processed more deeply because understanding a joke requires cognitive effort to resolve incongruity, creating stronger memory traces (the distinctiveness account). The arousal account, proposed by McGhee (1983), suggests humor increases physiological arousal which enhances encoding. However, the evidence is mixed on whether humor aids memory for accompanying non-humorous information—it appears to do so only when the humor is relevant to the target material (StavATir, 2010; Schmidt & Williams, 2001).
Competing account — The rehearsal hypothesis (that humor aids memory because people rehearse funny material more) has been challenged by Summerfelt et al. (2010), who found evidence against it. The incongruity-only hypothesis was ruled out by Schmidt and Williams (2001), who showed 'weird' incongruous cartoons were no better remembered than literal ones. The relevance-moderation account (StavATir, 2010) suggests humor only aids memory for paired information when the humor is thematically relevant.
What the trials measured
Humorous sentences were better remembered than non-humorous sentences on free-recall, cued-recall, sentence recall, and word recall measures. The effect was attenuated in incidental learning and limited to within-subjects manipulations. Subjective humor ratings predicted memory independently.
Schmidt · 1994 · Multiple experiments; n varies
Original humorous cartoons were remembered better than both literal and weird cartoons, while literal and weird cartoons were equally well remembered. This ruled out the hypothesis that humor enhances memory solely through incongruity.
Schmidt & Williams · 2001 · not reported
Pun humor improved both recall and recognition memory following incidental encoding. Evidence suggested that rehearsal is not the cause of the humor effect, supporting an attention-and-distinctiveness account.
Summerfelt, Lippman, & Hyman · 2010 · not reported
Distinctiveness — robust. The humor effect has been replicated extensively across different stimulus types (sentences, cartoons, advertisements, educational lectures) and memory measures (recall, recognition). A meta-analysis by Eisend (2009) confirmed a positive effect of humor in advertising on memory and attitudes. However, boundary conditions are well-established: the effect is stronger for within-subjects designs, for intentional learning, and when humor is relevant to the target material.
Caught dominating attention

Dollar Shave Club viral marketing campaign
Dollar Shave Club's 2012 launch video 'Our blades are f***ing great,' created for $4,500, went viral with millions of views. The humorous approach led to massive brand recall and customer acquisition, eventually resulting in a $1 billion acquisition by Unilever. The campaign demonstrated humor's power to enhance brand memory.

Old Spice 'The Man Your Man Could Smell Like' campaign
Old Spice's humorous advertising campaign featuring Isaiah Mustafa became one of the most memorable ad campaigns in history. The humor dramatically increased brand awareness, recall, and sales, demonstrating the commercial application of the humor effect.

Humor in educational television for children
Zillmann et al. (1980) found that kindergarten and first-grade students who watched an educational TV program with humorous segments showed better memory for program content than those who watched the same program without humor. Researchers concluded humor increased attentiveness and led to better memory.
To weight it fairly
Deliberately rate the substantive content of humorous arguments separately from their entertainment value. Restate the core claim in neutral language to evaluate its strength without the humor boost.
Humor only aids memory for accompanying information when it is relevant to the material (StavATir, 2010). Irrelevant humor does not impair memory but provides no benefit either.
Catch it in the act
When a funny argument or joke sticks in your mind while serious counterarguments fade, the humor effect is at work. Ask yourself: would this idea seem as strong without the humor?

- Bizarreness EffectsiblingBizarre or unusual material is remembered better than common material, similar to but distinct from the humor effect—Schmidt & Williams (2001) showed humor is not merely incongruity.
- Positivity EffectsiblingPositive information is preferentially remembered, which may overlap with humor's emotional valence but is not identical to it.
