  Jevons thus recognizes that people are not homogeneous and that it would be wrong to create ‘representative agents’ depicting individual behaviour. In the case of large aggregates however, disturbing causes would cancel each other out. Here Jevons brings in the large number argument. If however specific policy questions are at stake, the heterogeneity of different societal subgroups has to be accounted for. Jevons uses the concept of ‘character’ in order to bridge the gap between universal theory and characteristics of specific subgroups in society, as we will see in the next section.
