I didn't make any claim one way or another, I was just saying that any consensus in academia is going to be backed up by some sort of research and evidence.
And anything you inferred as talking down to you was a misinterpretation on your part.
We're talking about anthropology/history here. People spend their entire careers researching things like this and publishing papers on it.
To make a claim like this requires evidence. Historical records would exist that some person at some point gathered together and published a peer reviewed article on.
If no sources or peer reviewed articles exist on the topic other than a few blog posts, then it's extremely likely it's a pile of horse shit.
In order to reach a consensus like that, you have to have supporting evidence that it's true. Otherwise that consensus should absolutely be challenged.
Most symptoms of the "milder" mental disorders (depression, anxiety, adhd, etc.) are things that everyone experiences at some point in their lives.
It's the degree of experience, frequency, and impact that differentiate the two. Also, when those symptoms don't have an environmental/situational/logical cause.
For example, being too anxious to go out with friends, or compulsively checking that the stove is off even though you know damn well it hasn't been turned on in a month. Also, being sad because your pet died isn't a mental disorder like clinical depression.
The line between the two is definitely fuzzy, but psychology is a super complex topic.
Writing a mathematic proof is a whole different ballgame than figuring out the solution to a problem. You have to definitively prove that the solution is applicable to any problem matching the criteria.
