As you suggest, when we offer policy prescriptions to societal ills, it is important to acknowledge this complexity.

I acknowledge the profound and pervasive effect of the situation on human thought and behavior. We do well to recognize this effect and account for it. Yet there is more to our disagreements than the situation. “How will we ever close the gaps,” if we are consistently steered to opposing moral, ideological, and political intuitions by our different temperaments? We’ve got to keep our individual differences in mind even if they are difficult to tease apart from the situation. The self-segregation of people into distinct groups and markets by moral, ideological, and political interests is only partially an effect of the situation. The other profound influence is a basic and profound difference in individual temperament. Maybe this can be described as the “internal situation.” Nevertheless, the above quote might be read to imply that we do not need to take account of such individual differences. I think that would be a mistake.
