This is just objectively not true. Population-level data has been used to establish all sorts of things about psychological disorders. You mention your experience of parental abuse causing depression: it absolutely does! And that relationship was established unequivocally decades ago by showing the correlation between adverse childhood events and the development of depression.

One of your specific complaints is that depressed people do not report the causes of their depression very accurately. This is also true! The unreliability of depressed people is emphasized in the diagnostic criteria, and a good psychologist will probe for other underlying issues. But researchers absolutely can identify causes of depression by supplementing self-reports with objective data.

> The problem with the psychology field is that it has an obsession with "data".

Yeah, that's how science works. By collecting evidence you can make descriptive statements about the world. If psychologists didn't present data, they would be instead be rightly criticized for presenting data.

It sort of seems like you jump from the poor accuracy of depressed people's self reports to dismissing the entire field of psychology. Humans are complicated and messy, but we do know a ton about psychological disorders.

For what it's worth, I was also reacting to this assertion:

> The first step to overcoming depression is to discover what is making you depressed. If someone is still depressed, they probably don't know what is making them depressed, and so their "data" is just noise.

This was not my experience, and hasn't been the experience of others I know who have been depressed. The condition is often caused by an acute stressor, but in my case it was caused by a lack of social interaction and exercise during the pandemic. Trying to identify the "cause" of my feelings wasn't helpful because they weren't rational - instead I had to get out of bed, exercise, eat, and socialize until the episode cleared.
