Taking criticism seriously

Criticism is not like a fluid you can pour into a mind, and the mind is not like a bucket able to passively receive whatever you want to pour in. As Karl Popper said, there is no such thing as instruction from without.

Why did my mother’s coercive words fly out of my mouth?!

Anti-rational memes are not only passed from parents to children, they exist more widely in our culture. This is why other people seem to feel so free to judge and criticise you if you are taking your child seriously, and it is why complete strangers in supermarkets tell you to keep your child under control. And it is why the corresponding anti-rational meme in your own mind has you feeling rebuked, ashamed, upset, and defensive.
