This week, how one of the worst ideas in science got a big push from a bad study… and intellectuals of the day lapped it up. We speak to science writer Carl Zimmer and Prof. J. David Smith, whose research helped get to the bottom of this disturbing story.

UPDATE 05/25/18: This episode has been updated. A previous version said that the 'good' side of the Kallikak family included someone who had signed the Declaration of Independence. It now says that the 'good' Kallikak family member married into the family with the relative who signed the Declaration of Independence.

There are a lot of fads, blogs and strong opinions, but then there’s SCIENCE. Science Vs is the show from Gimlet Media that finds out what’s fact, what’s not, and what’s somewhere in between. We do the hard work of sifting through all the science so you don't have to. This season we tackle alcohol, fasting diets, DNA tests, race and the fertility cliff.
