In recent years, more and more scientists are preregistering their studies. Should you too? In this OSCoffee, we will tackle questions such as, for example, “Why is preregistration important for the scientific process?”, “Why should I preregister my work?”, “Do preregistrations help in getting published?”, “Do I have to pay to preregister my study?”. To this end, we will provide both economics and psychology perspectives, as well as offer you a hands-on experience by walking you through two different preregistration platforms.
