We provide real-world evidence of the importance of observability in supporting large-scale cooperation. We show that observability triples participation in an energy efficiency program, and is over four times as effective as offering a $25 monetary incentive. Furthermore, we provide evidence that reputational concerns are driving our observability effect.
