Scientists have to follow a lot of rules. We have IRB rules, journal submission rules, university rules - lots of rules. But some of the most important rules in science aren't rules at all - they are norms. Guiding principles that shape the work we do. In this episode, we discuss a classic paper by the sociologist Robert Merton on 4 norms that govern scientific work. Are these norms an expression of scientific values, or just a means to an end? How well do scientists follow them, individually or collectively? Is science doing as well today as Merton thought it was back in 1942 - and is following these norms really the way to make science work right? Plus: We answer a letter about question to ask a prospective PhD advisor.
