Learning From Pairwise Preferences: An Introduction to the Bradley Terry Model

# When Your Gut Choices Can Build Better Rankings Companies increasingly use simple head-to-head comparisons—like asking customers which of two products they prefer—to figure out what people actually want, rather than relying on traditional rating systems.
