Internet Digest: the things that are interesting in my news feed

Rather than pretending to come up with original content today, I'll just link you to all the things I read and vaguely cared about this morning.

This post on unemployment and education level was interesting, but I wish it had a graduate degree line.  Might help inform some of our earlier discussions about the goodness/badness of grad school.

Apparently Paul Krugman's is the right blog to read.
Here, we use Paul Krugman, a New York Times columnist, as an example to show how our PVS system works.
From a random sample of his columns and television appearances, we tallied 17 testable predictions. Krugman was awarded one point if he either predicted an event would happen and that event took place, or if he predicted an event not happening and that event ultimately did not take place. When Krugman made a prediction and the opposite outcome occurred, we subtracted one point from his total. Hedged predictions did not receive any points.
Of the 17 predictions, there were 15 instances where Krugman made a correct prediction and only one instance where he made an incorrect prediction. With the single hedged prediction included, Krugman’s final tally was +14. We took the final tally (14) and divided that by the total number of testable predictions made (17), which we then multiplied by ten. Krugman’s final score was 8.235#.

All in all the internet has given me a very validating morning.
