Reactance

We do the opposite of what we are told when we feel our freedom is being restricted.

The need to act fast Avoiding irreversible decisions

Reactance is an unpleasant motivational arousal (a negative emotional reaction) that arises when people experience a threat to or loss of their free behaviors. It is the tendency to want something more if told they cannot have it. The theory was developed by psychologist Jack Brehm in 1966. Warnings like 'You cannot do X' often provoke the very behavior they are trying to prevent.

What it looks like in the wild.

Would you catch it?

Recognising a definition is not the same skill as spotting it.

Two scenarios from the app, with distractors drawn from the same family of biases — which is what makes them hard.

Scenario 1Which bias?

A public health poster says 'Stop Smoking Today—It's an Order.' A smoker, feeling their personal choice is being attacked, lights up a cigarette right in front of the poster.

Scenario 2Which bias?

A boss assigns a new, rigid procedure for all reports. A longtime employee, who felt the old way worked fine, starts deliberately using the old format, thinking, 'They can't make me.'
