Another exemplary paper of why you need to beware of reversed causality. Since infection with T. Gondii is much more likely if you are less cautious with food and animals, it is very much possible that the causal link is actually reversed. It's also worth pointing out that current research has cast major doubt on the old idea that toxoplasmosis causes any psychological effects in humans [1]. While it might sound cool…
Mechanistically, the observed linkages between T. gondii infection and entrepreneurship among students, professionals, and nations have several potential interpretations. Given the correlational nature of the study, observed patterns may not be causal; for example, higher risk-takers could be more likely to be both entrepreneurial and exposed to T. gondii (e.g. by consuming raw/undercooked meat), thereby driving the correlation. Although causality cannot be inferred, the […]
