Key researchers

First described in 1975
Psychological mechanism
Control heuristic. The brain uses cues like choice involvement and familiarity as proxies for control. Even when outcomes are purely random these cues create the subjective feeling of influence.

Below is a realistic scenario. Read it, then choose what you would do. The feedback will show whether a cognitive bias influenced your choice — not to judge, but to reveal the pattern in action.
Thought Experiment
This experiment places you in a realistic decision. Your instinctive choice will reveal whether bias is at work.

Debrief
The illusion of control is why gambling is so compelling. The brain treats involvement as control. When you choose your own lottery numbers or shake the dice a certain way you feel more in control even though the outcome is completely random. The separation of skill-based and chance-based domains is critical.
