"It is a vast, and pervasive, cognitive mistake to assume that people who agree with you (or disagree) do so on the same criteria that you care about."

Previous Quote

If we take two people who have exactly the same sort of lesion or area of damage in the brain and then we do cognitive tests on them, you know, one person might have a very severe deficit in a certain area of thinking and another person might not with the same exact lesion. So there is a lot of differences and you can't just look at one brain and understand the whole picture.
