Economic physics v economic psychology

I'm no economist. I was really interested in it until I took my first course in college, and I lasted a week. 40 years later and I'm still recovering from college.

But it seems to this nobody, that there's two factors. One is the reality of economic interactions, which is as fixed as a lever's function. The other is the psychology of economics as you say - psychologically, one either understands gravity or doesn't, with predictable consequences, yet look at how many attempt to defy it!

The physics of economics is consistent up and down the everyday scale from home economy to planetary.

The psychology... Well according to Asimov, you have to have a pretty big sample base to process humanity's choices.

Think I'll go revisit Free to Choose.
