# Eidos Research

> Eidos is a research and technology company exploring how people and institutions make decisions under uncertainty.

Eidos Research, LLC studies the relationship between evidence, judgment, and action: how beliefs form, how they change, and when they provide a basis for a decision. Its public areas of inquiry are evidence, judgment, action, and learning. Brandon Stiles is CEO.

The website includes an interactive evidence-and-belief experiment. It uses constructed observations and a simplified two-hypothesis Bayesian model with equal starting probabilities and independent observations. It illustrates how supporting and conflicting evidence change beliefs. It is not collected data, research findings, validation results, or a demonstration of an Eidos product.
