The experiment was done in 200 villages. And in some cases the information is broadcast by the seeds. How were the seeds selected, randomly or not? Villagers with higher status might be intrinsically different from other people in behavior. Also, what's the average education level of the villages? Is it high enough to understand the pamphlet?
