"What is the #economy? I would argue that it doesn't exist in the physical world. It is a product of our #imagination. It is made out of #ideas. It does have an effect on the physical world. But the imagined order that we have is not succeeding."

Today #RWRI 10, we discuss:
How the "calibration" ranking by BS Vendor @juliagalef is not even wrong

1) In real life, you shb be calibrated in payoff space, not in frequency space. Someone right 80% abt Russian Roulette won't survive, option traders can be right ~1%
#ergodicity
2) Which is the idea of #skininthegame as a filter. The ONLY filter.

Verbal predictions do not map to anything real, as they penalize those wrong most of the time in skewed payoffs and favor bureaucrats who optimize in frequency space.

Survival=calibration.
Lookup the story In Fooled by Randomness about the trader who thinks the market is "more likely to go up", yet is very heavily short.
