Evaluating Extraordinary Claims
To demonstrate the problem, I did a simulation where I generated 480 random numbers per subject, representing the 480 time slices in the experiment. I repeated this generation of random numbers 20 times. I compared the send and no-send intervals of random numbers using a T-test; none of the 20 trials found a…

Traffic Experiments -- How to clear traffic jams
Once upon a time, years ago, I was driving through a number of stop/go traffic waves on SR 520 at rush hour in Seattle. I decided to try something. On a day when I immediately started hitting the usual "waves" of stopped cars, I decided to drive smoothly. Rather than repeatedly rushing ahead with everyone else, only…
