34. Stanley L. Engerman and Kenneth L. Sokoloff, in Factor Endowments, Inequality, and Paths of Development Among New World Economics, no. w9259, National Bureau of Economic Research, 2002, argue that it wasn’t so much the risk of death to colonists that shaped the population makeup of colonies, it was more the nature of the land they colonized. In the tropics, colonies were built on a model of exploiting slaves or natives in mines or on large plantations growing crops like sugar and tobacco. Outside the tropics, the crops that did well could be grown on small farms as successfully as they could on large ones, so demand for slave labor was lower and homesteading made sense. As the areas where tropical diseases were the greatest threat and the areas where plantation farming made sense largely overlap, the stories reinforce each other.

If the child is infected before he or she has destroyed the inherited immunoglobulin, it will help the child survive the disease and develop longer-term resistance.

52. So far, the researchers working on parasite stress haven’t been able to convincingly demonstrate that it is the behavioral response to communicable disease that dominates in the relationship between quality of life and levels of infection. The best they have managed is to note that measures of parasite stress dating back to the 1930s are related to current levels of violence, xenophobia, and so on. But countries that were healthier, richer, and more peaceful in the 1930s remain healthier, richer, and more peaceful today, so that the relationship holds between modern development outcomes and seventy-year-old parasite stress isn’t fully reassuring as evidence of what causes what. Even if parasites play a role in violence and distrust, it might be through more the direct impact of illness or some other mechanism than greater distrust of strangers. For example, Matteo Cervellati et al., Malaria Risk and Civil Violence, Munich Discussion Paper 2017–8, University of Munich, suggest that malaria outbreaks are linked to civil unrest because they cause sizeable economic losses through incapacity and medical payments rather than through any change in attitudes.
