Beyond Fear: The Psychology of Security

Security is both a feeling and a reality. And they're not the same.

Most of the time, when the perception of security doesn't match the reality of security, it's because the perception of the risk doesn't match the reality of the risk. We worry about the wrong things: paying too much attention to minor risks and not enough attention to major ones. We don't correctly assess the magnitude of different risks. A lot of this can be chalked up to bad information or bad mathematics, but there are some general pathologies that come up over and over again.

  • People exaggerate spectacular but rare risks and downplay common risks.
  • People have trouble estimating risks for anything not exactly like their normal situation.
  • Personified risks are perceived to be greater than anonymous risks.
  • People underestimate risks they willingly take and overestimate risks in situations they can't control.
  • Last, people overestimate risks that are being talked about and remain an object of public scrutiny.
