Scaling up occurs after key elements of a program are tested and a successful program is taken up by other settings or continued in the same setting; it is considered good practice because it occurs after key elements have been tested, rather than rolling out a program at scale without first testing if effects are as predicted. Social and personality psychologists are often involved in the first phase – the program development and initial evaluation. But what happens next has not been the focus of social psychological inquiry. The assumption has been that all the theoretically interesting work happens in the initial test and the rest is ‘just’ application. However, programs often fail at the point of Scaling up; initial results fail to replicate when programs are tried again, at larger scale, in a different setting or different time. We focus on an emerging field, the social science of scaling up.
