Sajedeh Rasti is a PhD candidate in Human–Technology Interaction at Eindhoven University of Technology, specializing in open science, research transparency, and methodological rigor. Her work explores how preregistration and registered reports can improve the credibility of research.

In this Open Science Summer School talk, she explains the philosophy and practice of preregistration, linking it to Karl Popper’s falsification, the idea of severe testing, and how questionable research practices (QRPs) like p-hacking and HARKing undermine findings.

You’ll learn:

- Why preregistration supports falsifiable, bias-resistant research
- Common pitfalls and misconceptions (it’s not a “quality badge”)
- When preregistration doesn’t make sense (exploratory, qualitative, secondary analyses)
- Tools for transparency like open lab notebooks and GitHub
- Valid reasons to deviate from preregistration plans
