As opposed to small groups, where the rationality of the individual and the collective are more easily held in line, larger groups (or interests) naturally produce a greater opportunity for individual members to free-ride (Olson, pp. 35-36). Interestingly, this produces the counterintuitive capacity for the “exploitation of the great by the small” (p. 37) in the process of interest articulation: in other words, it is inherently more difficult for groups formulated around large interests – such as the environment – to overcome smaller, more well-organized interests (e.g., the American Petroleum Institute).
