Wow, just wow!

Via Thomas Lumley:
You may have heard about the famous Hawthorne experiment, where raising light levels in a factory improved output, as did lowering them, as did anything else experimental. The original data have been found and this turns out not to be the case.
The mind boggles at just how often I have used this example and how wrong it was.  I have read the paper once, not that closely, but the overall impression I have is that Levitt is correct here.
