About

Bias Handbook

Features
Read full description

Bias Handbook is a curated reference guide to the cognitive and behavioral biases that shape human thinking, judgment, and decision-making โ€” now with visual diagrams for every bias and a built-in library of the behavioral-design frameworks professionals use to change behavior. Explore well-known biases such as confirmation bias, anchoring, survivorship bias, framing effects, the availability heuristic, and many more โ€” each with a clear definition, real-world examples, a visual diagram, and links to related biases. New in this version: the Frameworks tab. Go beyond spotting biases to actually applying behavioral science, with 12 of the field's most trusted frameworks โ€” COM-B, the Behaviour Change Wheel, the Theoretical Domains Framework, the BCT Taxonomy, EAST, MINDSPACE, Nudge, the Fogg Behaviour Model, Self-Determination Theory, Dual-Process (System 1/2), the Theory of Planned Behaviour, and the Transtheoretical Model. Each is explained in depth, illustrated with its own diagram, and cited to its original peer-reviewed or government source. Designed for students, researchers, product teams, behavioral scientists, marketers, investors, and anyone curious about how the mind works, Bias Handbook makes complex behavioral concepts easy to understand and accessible anywhere. Features: โ€ข A comprehensive, growing library of cognitive and behavioral biases โ€ข Visual diagrams โ€” every bias has a clean, color-coded schematic that captures the idea at a glance โ€ข NEW โ€” Frameworks tab: 12 in-depth behavioral-design frameworks (COM-B, EAST, Nudge, Fogg, and more), each with its own diagram โ€ข Diagnostic questions, end-to-end worked examples, implementation playbooks, templates, and practice exercises for every framework โ€ข Every framework cited to its original trusted source โ€ข Fast in-app search across names, aliases, and summaries โ€ข Filter by category โ€” Decision-making, Memory, Belief & Probability, Social, and Self-perception, each with its own color โ€ข Bias of the Day โ€” a fresh bias on the banner the first time you open the app each day โ€ข Bookmarks โ€” save biases worth revisiting in a dedicated tab โ€ข Personal notes โ€” capture how each bias shows up in your work or life, with a tab listing every bias you've noted โ€ข Daily reminders โ€” set a time for a gentle nudge to learn one bias a day โ€ข Clean, intuitive browsing experience โ€ข Cross-references between related biases โ€ข An educational reference for psychology and decision science โ€ข Regular updates with new content Built by the Center for Behavioral Decisions, a research and consulting unit working at the intersection of behavioral economics, psychology, and decision science. Understand how biases influence decisions โ€” and learn the frameworks to change behavior in everyday life and work.
