ABSTRACT
Social comparison theory (Festinger, 1954a, 1954b) has a most peculiar history. Pictorially, this history is like the tracks of a squirrel in my snow covered backyard. The tracks zig zag unpredictably and then disappear near an elm, to next be seen near a maple, or the tracks may be obscured by those of other squirrels, or rabbits. In this chapter, I follow the tracks and draw the bigger trees through 1977, with a few additional comments about the early 1980s.
