Isolating the Signal in Behavioral Data.
Applying time-series analysis and changepoint detection algorithms to measure the true impact of behavioral interventions, policy shifts, and environmental nudges.
Beyond Anecdotal Outcomes.
ChangePoints explores the intersection of behavioral economics and rigorous data science. We dismantle historical case studies, analyze real-world environmental data, and apply statistical frameworks to determine exactly when and why human behavior shifts. This is an open archive of methodologies, algorithms, and applied behavioral science.
