Geometric Rationality

Geometric rationality is my name for a cluster of techniques and behaviors that tend to maximize the geometric expectation (or equivalently maximize the expected logarithm) of natural features (of the world or the self). Geometric rationality techniques include Nash bargaining, Kelly betting, Thompson sampling, and (arguably) Bayesian updating. The posts in this sequence are relatively self contained, but draw on common themes.
