The availability heuristic is a mental shortcut where we judge how likely something is by how easily examples come to mind. Vivid or recent events feel more common than they are — which is why people may fear rare plane crashes more than common car accidents.

  1. We judge likelihood by how easily examples spring to mind.
  2. Vivid, recent, or dramatic events feel more common.
  3. It can distort our sense of risk and probability.
  4. Media coverage strongly fuels it.
