This document discusses how behavioral economics principles can be used for growth hacking and increasing conversion rates. It outlines seven behavioral principles: reciprocity, choice overload, anchoring, loss aversion, decoy effect, social proof, and scarcity heuristic. For each principle, it provides a brief explanation and examples of how it can be applied. It then presents an exercise where participants work in groups to integrate at least three of the principles into templates for a subscription plan, email, or e-commerce page. Suggested changes and additions are reviewed along with which approaches may be most effective.
