There were separate significant effects of city (Porto Alegreans moralized more than Philadelphians, and Recifeans moralized more than Porto Alegreans), of social class (lower-class groups moralized more than upper-class groups), and of age (children moralized more than adults). Unexpectedly, the effect of social class was much larger than the effect of city. In other words, well-educated people in all three cities were more similar to each other than they were to their lower-class neighbors.
