Economics is (now) about emotion and psychology.

Marketers know that if people you respect - perhaps laughably including entertainers and athletes - say they like a product, you're more likely to buy.

Physicists have a bias to aspire to be "seers" like Einstein rather than "craftspeople" who do simple and practical research. I have seen that in economics departments. The same must be true to some extent in other departments.

The good news is that, at least in economics, I've seen movement away from its overemphasis on mathematical models of purely rational behavior to a more eclectic and commonsense approach: research that is, among other things, more respectful of insights from psychology.

Consider our difficulties avoiding junk food and overspending. Such addictions were carefully planned-for by professional marketing teams.

Money management has been a profession involving a lot of fakery - people saying they can beat the market, and they really can't.

Stock prices are likely to be among the prices that are relatively vulnerable to purely social movements because there is no accepted theory by which to understand the worth of stocks....investors have no model or at best a very incomplete model of behavior of prices, dividend, or earnings, of speculative assets.
