I think the delivery might be sensational but I agree with the sentiment. Especially since you acknowledge that it isn't purely harmful. Normally I don't watch short form video but occasionally I do and I do feel it's a somewhat different state of mind. I would be worried about myself if I found it happening often.

I think it’s pretty clear the GP (and others) believe this is pseudopsychology bunk supported by neither any available evidence nor by professionals in the field.

It takes 1,000x less time and energy to come up with a pet theory de novo and sans any evidence than it takes to debunk. Without backing evidence provided for an idea, it should be as easy to dismiss out of hand as it was to create it in the first place.
