Homo economicus
The rationality implied in "Homo economicus" does not restrict what sort of preferences are admissible. Only naïve applications of the "Homo economicus" model assume that agents know what is best for their long-term physical and mental health. For example, an agent's utility function could be linked to the perceived utility of other agents (such as one's husband or children), making "Homo economicus" compatible with other models such as "Homo reciprocans," which emphasizes human cooperation.
