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.
It's not anti-science. She makes it very clear right from the beginning that what you hear from evopsych pundits is actually bullshit science being used by conservatives to justify their regressive worldview.
You would know that if you watched more than 3 minutes.
It's the title of the video. Video essayists rely on the algorithm, which encourages click-bait titles.
Also, it targets true bullshit evopsych professors and published evopsych papers, as well as the cultural image evopsych has in the current cultural context, which is a valid approach.
