bias

You judge risk by what you recall easily.

While the availability heuristic was indeed defined by Tversky and Kahneman in 1973, the specific study comparing perceived frequency of deaths from diabetes versus vivid events was conducted by Lichtenstein, Slovic, Fischhoff, Layman, and Combs in 1978.

You fear what you can imagine, not what is statistically likely.

Where this comes from

Study: Tversky and Kahneman, 1973
What the check found: The definition of the heuristic is accurate, but the attribution of the 'diabetes' example to the 1973 Tversky and Kahneman paper is incorrect.
Confidence: Well replicated

bias decision-making risk

You overestimate how long your misery will last.
You misremember why you chose what you chose.
You are far more certain than you are accurate.

One of these every day, and every one names the study it came from. When a finding is contested, it says so.
