The Truth About True Models:

Harish's Notebook - My notes... Lean, Cybernetics, Quality & Data Science.

I recently came across Dr. Donald Hoffman’s idea of Fitness-Beats-Truth or FBT Theorem. This is the idea that evolution stamps out true perceptions. In other words, an organism is more likely to survive if it does not have a true and accurate perception. As Hoffman explains it:

Suppose there is an objective reality of some kind. Then the FBT Theorem says that natural selection does not shape us to perceive the structure of that reality. It shapes us to perceive fitness points, and how to get them… The FBT Theorem has been tested and confirmed in many simulations. They reveal that Truth often goes extinct even if Fitness is far less complex.

Hoffman suggests that natural selection did not shape us to perceive the structure of an objective reality. Evolution gave us a less complex but efficient perceptual network that takes shortcuts to perceive “fitness points.” Evolution by natural selection…
