I mean if google is to believed about the definition of mansplaining:
Mansplaining — the combination of "man" and "explaining" — is a colloquial expression used to describe situations in which a man provides a condescending explanation of something to someone who already understands it.
She manages to show she doesn't understand how social science works very quickly.
At
1:24:03 before it hits 1:24:19 (yes not even a minute into the segment) she states the only way we can test heritability is through twins. This is false, we have found multiple correlations between parents and children on numerous occasions and we are still finding new ones. Twins are one of the most reliable they are far from the only ones that have show statistical/practical significance. If she made the most basic research in heritability she would know this.
Then right after she points out how rare identical twins are. This is true as they only consist of about 0.5% of births. There were 4,265,555 born in 2006 in the United States which means there are tens of thousands of people turning into adults this year alone which means we can get statistically significant sample sizes. If you knew expected value you would know this and you would know expected value if you took your intro to statistics for psychology class.
The she states how we can't completely control twin studies because we can't separate them. Unfortunately psychology has a history of less than ethical studies and there have been times where twins were separated at birth for the sake of study. This is one of the first things they cover when going over twin studies and ethics in psychology.
Using what we found out in those twin studies and heritability studies of other siblings vs twins, it's not hard with statistical software to control for these factors. You would know this if you took a research methods class because they should cover multivariable correlations.
She then goes on to cover that ancient fraudulent study that tried to show that IQ was 80% heritable (which is is not, not that IQ is a very strong psychometric) and then goes on to try to debunk the more recent ones which either psychology already acknowledges as bad or she dismisses for not controlling for everything. In social science, it is not possible to control for everything nor does it promise to. This is why psychology is statistical and cares more about trends. Again, they cover this the research methods class.
In a very short amount of time she managed to show some very key gaps in her knowledge, namely the foundational philosophical context in which cognitive-behavioral psychology operates. It isn't just two books I read, they are the basis on which modern psychology operates on. Messing up this quickly and this badly is not a good sign for the rest of the video. If I saw a piece of a video saying how Columbus and the indigenous Americans were total besties I would also be very skeptical about the rest of the video also.
I cover why she lost a lot of credibility so quickly with me right above here. The problem is less the studies she cites or debunks (a lot of the studies she debunks are indeed garbage) it's that she does not know how to interpret them and show a lack of understanding of some fundamentals of psychology. It's not just that she managed to make incorrect statements, it's that she made those incorrect statement because she lacks understanding of core concepts of psychology. I tried to watch more of the video but she kept making the same basic mistakes over and over again and I just tapped out.
I don't need to her to tell me that a lot of popular evolutionary psychology is pseudo scientific. I have anthropology books on my bookshelf that can debunk them while still adhering the the basics of research methods.
I mean I took some psych classes and stats classes as part undergrad/grad school, read some additional textbooks in my free time and based of what I learned on there I found some fundamental issues with how the video is structured. I pointed out that it didn't take me very long to find structural issues with it and you should take what she says with a very large amount of salt.
Like it is understandable to side eye someone who dismisses an entire video off a small chunk but it is far from unreasonable to raise a red flag when that small chunk shows foundational gaps in knowledge that somebody would learn about in their literal first year of a psych program.
