“We preregistered our analyses with the Open Science Framework which facilitates reproducibility and open collaboration in science research…Our preregistration: Sheldon and Griffith (2017), was carried out to limit the number of analyses conducted and to validate our commitment to testing a limited number of a priori hypotheses. Our methods are consistent with this preregistration…” [3]
