We are used to believe that people gauged risk like actuaries, parsing out cost-benefit data when a merging car came too close or the crime rate spiked. But a wave of psychological experiments in the 1980s upended this thinking.
Researchers found that people use a set of mental shortcuts for measuring danger. Ideally, these shortcuts help people figure out which ones to worry and which to disregard. But they can be imperfect.
When you encounter a potential risk, your brain does a quick search for past experiences with it. if it can easily pull up multiple alarming memories, then your brain concludes the danger is high. But it offer fails to asses where those memories are truly representative.
The tendency cant out in both directs, leading not to undue alarm but undue complacency. Though flu kills tens of thousands of Americans every year, most people's experiences with it are relatively mundane.
"We're conditioned by our experiences,", said Paul Slovic, a University of Oregon psychologist." But experience can mislead us to be too comfortable with things."
We are also conditioned to heavily focus on new threats, looking for any cause for alarm. This can lead us to obsess over the scariest reports and worse-case scenarios, making the danger seem bigger still.
