Alexa and Yoel fight some more, this time over whether or not science should be value free. They consider a position taken by W. E. B. Du Bois, who argued that social change was only possible if scientists focused solely on finding truth. In the process, they consider whether scientists should ever keep findings to themselves, and discuss the merits of leaving the value judgments to the politicians. In the end, they somehow conclude that it is fine that they never justify their alphas. Next time, Alexa promises to find out what's happening on UA frat house lawns.
