Why not take your Bayesian decision theory and make a trading system? Invest your farm, and you'll make millions with ideas like, if a stock just had two upticks, isn't it a good idea to put a little money into an upward trending stock. Not only will you come to understand decision theory better, behavioral prediction better, you'll get paid to do it, and nobody else will get hurt!

To spell it out:

The stock market is anti-inductive by design. Statistical patterns that reflect market inefficiencies are supposed to disappear over time.

Most problems are not anti-inductive.

So yeah, "you can't even predict the stock market with your methods" is a pretty terrible argument against methods that were never meant to predict the stock market.
