What is the availability heuristic?

Estimating event likelihood based on how easily examples come to mind. Recent, vivid, or media-covered events are judged more probable than statistically justified.

Examples of availability heuristic in risk perception?

Plane crashes dominate fear (vivid, media-covered) while car deaths are underestimated. Shark attacks receive far more concern than falling coconuts, which kill more people.

Availability Heuristic Risk Overestimation Calculator

Formula Definitions

The Availability Heuristic Risk Overestimation Calculator works by applying a well-defined formula to the values you enter. Understanding the formula behind the calculation helps you interpret the result and check that your inputs are correct. Below we break down the key components that drive the Availability Heuristic.

The core formula used by this calculator is:

Result = f(inputs, settings)

Each variable in the formula has a specific meaning:

inputs — Values entered into the Availability Heuristic.
settings — Options, units, or parameters that adjust how the calculation is performed.
Result — Computed output for the chosen inputs and settings.
