It's funny you'd say "that’s his perspective of what the world thinks" when he's an academic doing a PhD on the subject chatting with other academics about the same topic.

I mean clearly psychology is a lot of "our area of study observes X and attributes Y as a part of theory Z". It's not a hard science where objective, absolute, undeniable measurements can be made.

But it's not some random dude just pontificating about social structures on the internet.

By your measure we should just throw all the great philosophers works in the toilet because "that's their perspective".
