What is it about?

There's a loop between what we know affecting what we see and what we see affecting what we know. We present a model that characterizes the interplay between learning and information gathering, whether it be eye movements or web searches.

Why is it important?

One risk is society becoming more fractionated and polarized as people seek out biased information that is consistent with their beliefs. Our model illustrates how these negative outcomes can occur, even when people gather information in a somewhat rational way. Small biases readily grow.


This line of work was launched many years ago and I find it rewarding that the basic intuitions and ideas still hold. The core principles seem relevant to everything from characterizing eye movements to filter bubbles to polarization of beliefs.
