Irrational Labs’ 3B Framework
The company’s 3B Framework organizes design around a specific behavior, barriers to that behavior, and benefits that may motivate it. The framework describes what the company does. The results of an actual project still need to be examined.
How to interpret evidence
Evaluate a consultancy’s results at the project level: the comparison group, outcome, sample, effect size, duration, and any costs or harms. A case study’s relative percentage change is different from an absolute percentage-point change.
DellaVigna and Linos (2022) studied 126 randomized trials from two nudge units and found an average effect of 1.4 percentage points. That pooled estimate is neither an audit of Irrational Labs nor an upper limit on all behavioral interventions.
