Curiosity
Why are people curious?
Curiosity arises when people notice a gap between what they know and what they want to know. It is strongest when they feel they almost know the answer, it activates reward regions of the brain and it improves memory. It can also lead people to seek unpleasant outcomes, and to avoid information they expect to hurt.
What the report found
- Curiosity is strongest when people almost know. People are most curious about answers they feel they nearly have, and least curious when they have no idea or are sure they already know.
- Curiosity helps memory. People remembered answers to questions they were curious about better, and in one study even remembered unrelated faces shown while they waited for an answer.
- Curiosity can override self-interest. People clicked about five pens that might give them an electric shock, against about two pens they knew would. Uncertain outcomes drew more clicks and left people feeling worse.
- Uncertainty can motivate, and be sold. People worked harder for an uncertain reward than for a certain larger one. In a survey of 7,422 gamers, spending on loot boxes was linked to problem gambling.
- Sometimes people would rather not know. Investors look at their accounts less often when markets fall, and fewer than 10 per cent of people at risk of Huntington's disease are tested before symptoms appear.

Who it is for
For anyone who writes headlines, builds launches, designs games or teaches, and anyone who has watched one more episode.
How we work
Human Forces reports explain one deep human need and the many effects that grow from it. Every claim is graded Established, Emerging or Untested. Where researchers disagree, as they do on whether avoiding information is a mistake, both sides are set out before we say where we stand.
