In what universe can't you do experiments about biology or psychology?
Surely you can do some tests or experiments, but the staple of physics-like experiments, having identically prepared systems, is partially or totally lacking.
It's only unfortunate that the poorly qualified first paragraph has totally hidden the real question, which was at the end of the second paragraph. I guess I'll have to wait for the next open thread...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
