Reply All

Don't use it. This morning I received an email regarding attendance at a conference that I am not planning on attending. It turns out that it was sent to a list of people who should not have received it. I then received over 40 emails from people who were hitting reply all. First, a number of people thought it was necessary to inform everyone that they did not know why they were receiving the email. Then other people started replying to all that they should stop replying to all. These were professors at places like the LSE, Univ. of Chicago, and USC. Can't we all just hit delete?

Double Blind Studies

The Economist reports on the pseudo placebo effect in randomised control trials.

"In a new paper, Erwin Bulte of Wageningen University and his colleagues conduct a double-blind test of an agricultural intervention—that is, the treated don’t know whether they are receiving the treatment or the placebo. The treatment is a modern seed of cowpeas, the placebo is the traditional seed. As a second experiment in a different set of villages, they do a normal RCT where the treated know that they are receiving the modern seed. Comparing the results of both experiments reveals some striking results. When the farmers don’t know which seed they are planting, there is no difference between the modern and the traditional seed in terms of yield. When they do know that they are being treated, the modern seeds yield considerably more. What the authors call the “pseudo-placebo effect” therefore accounts for the whole effect that a typical RCT would have found."
