In this episode, we discuss the importance of consensus in science, both as means of establishing true knowledge and for determining which research questions might be worth pursuing. We also discuss barriers to reaching consensus and the different frameworks that are currently employed for trying to reach consensus among important stakeholders.  Shownotes The Popper quote is from: Popper, K.
