Here is my "general" medicine deck, mostly vocab and roots: https://ankiweb.net/shared/info/130158459

Here is my psychology deck, which includes cognitive biases (about half of the list I posted here; I'm still planning to make the rest), some personality psyc, and also a few taken and modified from Divia and Alex: https://ankiweb.net/shared/info/798225764

Here is my math deck, mostly vocab, with some graph theory: https://ankiweb.net/shared/info/952249083

Here is my statistics deck, mostly vocab, with quite a bit of notes on probability distributions (basically my idea from here): https://ankiweb.net/shared/info/2626280898

If you only want part of the deck, it's really easy to create that, just browse and filter by tag:DSTN (or something) and get rid of the rest.

I generally agree it's better to make your own, but think you can learn how to make them and take specific notes from others.

Gwern used to have his main deck available for download here, though I can't find it anymore (and didn't look that hard). I took some things from body language and vocab from it, although there was a lot of cultural stuff I was uninterested in.
