I am happy to announce the publication of our new work on the impact of arbitrary analytical choices on type I and type II error rates. We simulated reaction time data in a conflict task and analyzed the notable CSE effect in a multiverse manner. Worrying results:

Excited to share that my first PhD paper got published! We explored the effects of correctly vs. failing to model true interactions in data. Can model misspecification lead to reversed conclusions? Which model generalizes better to a larger sample?
