Edit - Addendum: The video title is quite clickbait-y. The video doesn’t want to debunk any “serious” science, but rather investigates how badly done research with no reproducability or horrible statistical significance is used to influence the discourse in favour of regressive politics.
Why else would you judge the video after you’ve only watched the intro?
I judged the video based on the introduction. Which is part of the purpose of having an introduction: to decide whether it’s worth investing one’s time and attention in what’s being introduced.
The introduction mostly showed the style of the creator. And it also showed published evopsych papers which the video was about to debunk. It didn’t even mention any “idiot on the internet”.
