What methods do you use to study this?
Like I guess the main method one can use is to start with the symptoms and track backwards step by step along the known causes of such symptoms to identify causes that are out of whack, until one gets up to some major cause that’s treatable?
Alternatively, one could just throw stuff at the wall and see if it sticks, but it seems like it would be too noisy to work.
The tricky part is I’d think it’s very hard to enumerate the causes of the symptoms? What does it look like in practice?
Is it really the further data that becomes tainted, rather than the original data? Usually when you think longer about a subject, we’d think your opinions would become more rather than less valid.
