What behavioral science is behind these tools?
Each tool draws on a different branch of behavioral science. The Commitment Tracker is grounded in Gollwitzer's implementation intentions, Gottman's bids-for-connection framework, Cialdini's commitment-and-consistency principle, and Self-Determination Theory. The Decision Journal uses prospective-hindsight research from Mitchell, Russo, and Pennington, along with the Brier score for confidence calibration. Decide implements Gary Klein's prospective hindsight method — which Daniel Kahneman has called his favorite debiasing technique — alongside 13 other cognitive paths for working through hard choices.
