Please don't do that.
SheilaNaGig has again provided links and critical comment on a wide variety of sources and research results, comment and opinion, and taken pains to include concerns and caveats.
If you have concerns or doubts about the validity of any specific results linked to, do share them. This is a thread for review and discussion, as the title makes clear.
It's not a thread for sniping, and certainly not at someone who has made way more effort than you have to provide information and food for thought.
This is really hand-wavily judgemental. Have
you actually read any of the studies? If so, please share your thoughts on specifics.
My claims of authority tend to come out when I'm being doubted, not on the basis of what I've presented, but on the basis of others' beliefs about what I'm likely to present.
In science, it's commonly regarded as a good thing to be able to discuss matters without recourse to one's preconceptions of the source.
Interesting. My one-person observational study (of my mother) indicates that her chronic psychosis became significantly more pronounced on her immigration from a tropical country to the UK. There will be other factors, known and unknown, but this is something I want to investigate further, just for personal reasons.
It will likely turn out to be impossible to judge the relative contribution of various factors in this one case, but I'd still like to understand more about the potential causes.
