About 36 days later, according to psychologists at the University of Colorado who used an online survey to gauge people’s reactions to jokes about Hurricane Sandy:
The researchers divided the surveys into “during crisis” and “after crisis.” The day before the storm made landfall, people thought the tweets were pretty funny—they didn’t yet know it would be a tragedy. Over the next nine days, as people learned the extent of the damage, perceived humor declined. Participants found the tweets least funny 15 days after Sandy’s landfall. Then, it slowly started to be “okay” to find humor in the situation again, leading to a high point of humor 36 days after landfall. Humor fell again after that, and researchers saw another low point 99 days after the disaster. The study also showed that during the first dip in perceived humor, participants found the tweets more offensive.
How the study informs our understanding of humor:
[A. Peter] McGraw and his colleagues argue these results provide evidence supporting the “benign violation theory” of humor. It states that “humor arises when something that threatens a person’s well-being, identity, or normative belief structure simultaneously seems OK, safe, or acceptable.” Or to put it more simply: “Humor requires threat, but not too much, or too little.”
So if you fear an approaching hurricane could actually hurt you, your interests, or someone you love, there’s nothing funny about it. If the threat has safely passed, its potential to generate humor rapidly retreats. But the moment when you feel you have dodged a bullet: That’s ripe for laughs. Humor, McGraw and his colleagues write, is a great example of “the human capacity for taking a source of pain and transforming it into a source of pleasure.” (In that way, it’s like the blues.) This ability, they add, “is a critical feature of the psychological immune system.”
