Michael Blastland on the Hidden Half

<p>Author Michael Blastland talks about his book The Hidden Half with EconTalk host Russ Roberts. Blastland argues that the deeper you delve into science, medicine, astrophysics--pick a topic--the more you realize there is a lot we don't understand. Things we can't explain. Blastland believes we would all do well to admit that and stop pretending that everything is knowable and every problem solvable.</p>
