Still, it comes at a cost. "Curiosity killed the cat" isn't a cliché for nothing. The number of deaths in horror movies alone from someone saying, "I hear a noise in that abandoned house, I think I'll go investigate" is staggering. People will take amazing risks out of nothing but sheer inquisitiveness -- so the gain in knowledge must be worth the cost.

What they found was that even when told that there was a higher than 50% of being shocked, most subjects were still curious enough to take the risk. The authors write:
Curiosity is often portrayed as a desirable feature of human faculty. However, curiosity may come at a cost that sometimes puts people in harmful situations. Here, using a set of behavioural and neuroimaging experiments with stimuli that strongly trigger curiosity (for example, magic tricks), we examine the psychological and neural mechanisms underlying the motivational effect of curiosity. We consistently demonstrate that across different samples, people are indeed willing to gamble, subjecting themselves to electric shocks to satisfy their curiosity for trivial knowledge that carries no apparent instrumental value.The researchers added another neat twist -- they used neuroimaging techniques to see what was going on in the curiosity-driven brain, and they found a fascinating overlap with another major driver of human behavior:
[T]his influence of curiosity shares common neural mechanisms with that of hunger for food. In particular, we show that acceptance (compared to rejection) of curiosity-driven or incentive-driven gambles is accompanied by enhanced activity in the ventral striatum when curiosity or hunger was elicited, which extends into the dorsal striatum when participants made a decision.So curiosity, then, is -- in nearly a literal sense -- a hunger. The satisfaction we feel at taking a big bite of our favorite food when we're really hungry causes the same reaction in the brain as having a curiosity satisfied. And like hunger, we're willing to take significant risks to satisfy our curiosity. Even if -- to re-reiterate it -- the person in question knows ahead of time that the information they're curious about is technically useless.
I can definitely relate to this. In me, it mostly takes the form of wasting inordinate amounts of time going down a rabbit hole online because some weird question came my way. The result is that my brain is completely cluttered up with worthless trivia. For example, I can tell you the scientific name of the bird you're looking at or why microbursts are common in the American Midwest or the etymology of the word "juggernaut," but went to the grocery store yesterday to buy three things and came back with only two of them. (And didn't realize I'd forgotten 1/3 of the grocery order until I walked into the kitchen and started putting away what I'd bought.)
Our curiosity is definitely a double-edged sword. I'm honestly fine with it, because often, knowing something is all the reward I need. As physicist Richard Feynman put it, "The chief prize (of science) is the pleasure of finding things out."
So I suspect I'd have been one of the folks taking a high risk of getting shocked to see how the card trick was performed. Don't forget that the corollary to the quote we started with -- "Curiosity killed the cat" -- is "...but satisfaction brought him back."
In the midst of a pandemic, it's easy to fall into one of two errors -- to lose focus on the other problems we're facing, and to decide it's all hopeless and give up. Both are dangerous mistakes. We have a great many issues to deal with besides stemming the spread and impact of COVID-19, but humanity will weather this and the other hurdles we have ahead. This is no time for pessimism, much less nihilism.
That's one of the main gists in Yuval Noah Harari's recent book 21 Lessons for the 21st Century. He takes a good hard look at some of our biggest concerns -- terrorism, climate change, privacy, homelessness/poverty, even the development of artificial intelligence and how that might impact our lives -- and while he's not such a Pollyanna that he proposes instant solutions for any of them, he looks at how each might be managed, both in terms of combatting the problem itself and changing our own posture toward it.
It's a fascinating book, and worth reading to brace us up against the naysayers who would have you believe it's all hopeless. While I don't think anyone would call Harari's book a panacea, at least it's the start of a discussion we should be having at all levels, not only in our personal lives, but in the highest offices of government.
