What is reactance?

When we feel our freedom to choose is being threatened, we push back — sometimes doing the very opposite of what we're told, even against our own interest.

The mechanism is a drive to protect autonomy: a rule, ban or hard sell is read as a loss of freedom, and we restore the feeling of control by resisting it. The forbidden option can even become more attractive simply because it was forbidden.

Example: Tell a teenager a certain band is "trash you shouldn't listen to," and interest in that band often goes up. A blunt "you must do this now" can make a willing person suddenly reluctant — the pressure, not the task, triggers the refusal.

Tip: To persuade, preserve the other person's sense of choice ("it's up to you, but here's why…"). Heavy-handed orders breed the opposite of compliance.
