Progress comes from disconfirming evidence.

And yet it is emotionally hard to receive disconfirming evidence.

It makes people do a defensive crouch--which then makes it even harder for them to receive it, in a toxic spiral.

How to create an environment where it can be low stakes enough so people receive it without getting defensive?

That requires careful work to create and maintain a psychologically safe space.

Psychologically safe spaces create the space to receive disconfirming evidence; to have unsafe thinking; for maximal growth and innovation.
