Data analysis workflows in many scientific domains have become increasingly complex and flexible. To assess the impact of this flexibility on functional magnetic resonance imaging (fMRI) results, the same dataset was independently analyzed by 70 teams, testing nine ex-ante hypotheses. The flexibility of analytic approaches is exemplified by the fact that no two teams chose identical workflows to analyze the data. This flexibility resulted in sizeable variation in hypothesis test results, even for teams whose statistical maps were highly correlated at intermediate stages of their analysis pipeline. Variation in reported results was related to several aspects of analysis methodology. Importantly, …

The current study examines the moderating role of traditional machismo on mental health outcomes. We hypothesized that machismo would enhance the effects of stressors that are incongruent with traditional machismo beliefs (discrimination, adverse childhood experiences [ACEs], and fear of deportation) on depression and anxiety outcomes but would not enhance stressors that are congruent (harsh working conditions and poverty) on depression and anxiety. Participants were 190 male Mexican migrant farmworkers. As hypothesized, endorsing high traditional machismo was associated with stronger effects of fear of deportation and discrimination on depression outcomes compared with low traditional machismo. The interaction of machismo and …
