Reverse psychology
Not a bias
A persuasion tactic where someone argues for the opposite of what they want, counting on the other person to push back and do the desired thing. It works by triggering reactance, and it steers us most when we don't notice it.
There is little direct research on how well reverse psychology works; most evidence comes from reactance studies and people's own reports of using it.
In everyday life
A parent tells a picky child 'you probably wouldn't like broccoli anyway,' and the child insists on trying it.
A car salesperson says, 'Honestly, this model might be too much car for you,' and you find yourself arguing for why you should get it.
Why your mind does this
Keeping our freedom to choose and our standing in a group protects us from being exploited or pushed out. Sticking with what already works, and avoiding choices we can't undo, limits the damage of a bad call. These habits likely helped people get by in small groups, where losing status or making a costly mistake could be serious.

How to spot it
Notice when someone seems to be steering you away from something in a way that makes you want it more.
What you can do
When someone tells you not to do something, ask what they would gain if you did it anyway.
