The Haldeman Moment

H.R. Haldeman was the White House Chief of Staff for President Nixon. As the Watergate/Pentagon Papers scandal was slowly unfolding, he at one point tried to explain how the revelations damaged the administration. In doing so, he accidentally composed the most damning accusation of his own administration's wrongdoing: "But out of the gobbledygook, comes a very clear thing: you can’t trust the government; you can’t believe what they say; and you can’t rely on their judgment; and the implicit infallibility of presidents, which has been an accepted thing in America, is badly hurt by this, because it shows that people do things the president wants to do even though it’s wrong, and the president can be wrong."  If anybody has done a better job of summarizing the failures of the Nixon administration in five lines or less, I am not aware of it. Though of course, the best summary in five WORDS or less was given by Nixon's famous one-liner: "I am not a crook! Which,...

What Genghis Khan, but Elizabeth Can't

One of my ongoing research projects is on the Mongol invasions. Doing some background research, I realized there's an interesting asymmetry between male and female rulers, in terms of available imperial sexual strategies. Say that the Mongol hordes have just finished annexing another city along their ever expanding frontier. Let's call it Elbonia . In this case the local elite had the good sense to surrender peacefully, and accept the Mongols as their rightful overlords. Everybody knew that if they put up a fight, the Mongols would typically exterminate a significant proportion of the local population, and enslave the rest. What did the Mongols want from Elbonia? Well first of all, obviously they didn't want the inhabitants to ever attack their other dominions, regardless of any preexisting local feuds which may have existed. Secondly, they wanted them to send them money or tradable goods regularly. And thirdly, they wanted them to furnish soldiers for use in their next...

Was any other car company gaming emission standards?

As most of you already know, Volkswagen was recently caught cheating on emission tests. But were they really alone in doing so? The EPA data shows some suspicious patterns. Without getting too technical (in any case, the specifics are still unclear), there's a tradeoff between fuel efficiency, and NOx emissions. So for a given level of performance, the software that controls a modern diesel engine can be tuned so that it is more fuel efficient, but produces more NOx, or it can be tuned so that it is less fuel efficient, but produces less NOx. Since Volkswagen had problems meeting the NOx standards in the US, they decided to introduce software that detected when an emission test was being performed, and tuned the engine so as to decrease NOx production, in the process potentially worsening fuel economy relative to regular driving conditions. One possible outcome of this procedure is that the cars involved might actually have better fuel economy in real life conditions, tha...
