Seg. 1: The Data Behind Abortions | Seg. 2: Science Of Musical Taste

Segment 1: Researchers explain the data of who is receiving an abortion and why.

A study by Guttmacher Institute analyzed data from their 2008 and 2014 surveys on abortion and found an increase in the proportion of low-income women who received abortions. The University of California San Francisco conducted its own study following women who were able to receive an abortion, and contrasted the unintended effects of pregnancy with those women who were denied an abortion.

Segment 2, beginning at 23:10: The science that determines what music you like.

The chief architect of the Music Genome Project, describes how services like Pandora understand your taste in music. Most listeners aren't able to recognize all that goes on during the harmony of music, but trained musicologists analyze and code hundreds of variables related to each part of the songs you hear.
