UNDOING PROJECTForty years ago, Israeli psychologists Daniel Kahneman and Amos Tversky wrote a series of breathtakingly original papers that invented the field of behavioral economics. One of the greatest partnerships in the history of science, Kahneman and Tversky's extraordinary friendship incited a revolution in Big Data studies, advanced evidence based medicine, led to a new approach to government regulation, and made much of Michael Lewis's own work possible.

Really snug, but not uncomfortable
Size: Large, Color: Black
I don't know why these were so much tighter than all the other UA socks I've bought over the years. Not uncomfortable, just really tight when putting them on.
