The clarity of a single note played beautifully can be a highlight of a musical performance. Jason, Stevens, Ram, Beasley and Gleason (2016) do us a service by reminding us of the distilled clarity that arises from a pure note played well in community psychology. In science this can includes theory-based predictions that are tested and affirmed, or tested and either discarded or improved. Such clear moments can be uncommon and are special instances of scientific progress. Seeking such clarity of theory is important in advancing science. On the other hand, in my first year of college, an insightful music major commented that the history of progress in music appreciation is the story of listeners learning to appreciate new forms of dissonance. Science is music to the ears and minds of researchers and is about many things. Developing theory-based predictions that enable us to predict and control is an important one, but only one of many, as Jason and his colleagues (2016) note. For this brief comment I focus primarily on generativity as a one of several valuable functions of scientific theory that is given little attention by some of the sources Jason and colleagues cite in defense of their position.
