LEVYNA conducted field research in Mauritius
In an incentivized controlled lab experiment published in the Journal of Economic Psychology, Miloš Fišar together with members of LEVYNA and other colleagues show that there are no systematic effects of ovulatory shift on salient behavioral outcomes like risk preferences, rule violation, and exploratory attitude.
Some evolutionary psychology theories suggests that the impact of ovulatory shift on behavioral outcomes may play an important role in economic decision-making. The authors of the study run an incentivized controlled lab experiment with 124 naturally cycling females to test these effects. Using a within-subjects design, they compared different phases of the menstruation cycle of their participants and found no systematic differences in their risk-taking, rule-violating, and exploring behaviors.

In a new study published in Human Nature, LEVYNA was part of a team lead by A.K. Willard, studying how witchcraft beliefs affect social norms and behaviors. Specifically, researchers investigated whether witchcraft is regarded to be motivated by envy and how this notion influences community interactions. The findings show that, while witchcraft accusations were common, they were mostly directed at persons suspected of acting out of envy.
