1. The Cult of Overwork by James Surowieki. It's interesting to note that overwork generates cognitive dissonance where employees will be more dedicated to their job after working long hours because their actions indicate that they have been dedicated. Cialdini calls this form of influence "commitment and consistency."
2. NFL treats is cheerleaders quite badly if they are thought of as employees. If instead the NFL made clear that cheerleaders were joining an elite club and not a job, it would be interesting to see if the quality of cheerleaders fell significantly.
3. Some historically bad forecasts. It's interesting to note that Samuelson wasn't alone in his bullishness on the U.S.S.R. - most economists after World War 2 believed that planned economies, which could generate far more savings and investment, would win out in the end.
4. The Bill Gates 2014 letter. It's an interesting read that highlights some of the good that foreign aid does, but it is obviously biased in favor of what Mr. Gates has been spending billions of dollars on. One amusing part is in which Bill Gates uses the general population's cognitive bias of anchoring as a rhetorical flourish:
"When pollsters ask Americans what share of the budget goes to aid, the average response is “25 percent.” When asked how much the government should spend, people tend to say “10 percent.” I suspect you would get similar results in the United Kingdom, Germany, and elsewhere."
The actual amount is below 1%, and if Americans knew this they still might think it should be slightly lower. The 10% figure was only mentioned because it was within an order of magnitude of the erroneous 25% estimate. While foreign aid definitely saves lives in the short term, the letter definitely overstates their positive long term impact.
