Extremely poor wording in the first page or so: > This study showed Toxoplasma-infected and Toxoplasma-free participants of our cross-sectional study differed in three of four factors of PI34, scoring higher in Tribalism and lower in Cultural liberalism and Anti-Authoritarianism. - Is the author referring to the infected or to the free group here? > The stress-coping hypothesis suggests that many toxoplasmosis-associated changes, e.g., higher extroversion in infected women and lower in men, or lower suspiciousness of infected women and higher in suspiciousness of infected men (all in comparison to non-infected peers) can be interpreted as gender-dependent stress coping reaction. - Using “among infected men/women” in place of “of” would add a lot of clarity here. I believe I’ll stop reading the article.
