Availability Heuristic - people sometimes judge the frequency of events in the world by the ease with which the examples come to mind. (Tversky and Kahneman, 1973)
This availability heuristic research was extended to show that the more opportunities people were given to evaluate something, the higher they rated the overall score. (Winkielman & Schwarz, 2001; Schwarz, 1998 and 2004; Craig R. Fox, 2006)
Nonprofit institutions are human-change agents. Their product is a cured patient, a child that learns, a young person that grows into a self-respecting adult; a changed human life altogehter.
