The key take-away from this chapter is that social issues, such as housing and the nature of city life,
can be addressed by the same experiments as we addressed actual products. Social policy, therefore, and the
nature of what people want and what they will sacrifice, becomes, at least in terms of experimentation, one more
example of how research methods apply to a variety of different economic and social topics. That is,
understanding the public sector is probably no more difficult than understanding the private sector. Nor is it
difficult to export the research method to other countries, other cultures. With simply sensitivity to the local
problems of the population the tool which provides knowledge about how to sell products to people also now
provides knowledge about how to sell public policy to waiting citizens.
