Tilburg PhDs, back to four years...

A few months ago I was mean to our friendly colleagues in Tilburg, the Netherlands, when I protested their leading role in stimulating a trend toward three year PhDs (and the accompanying dumbing down/narrowing of the profession). Recall: http://itisonlyatheory.blogspot.com/2009/03/funded-phd-in-three-years.html
I am happy to report that in recent advertisements for PhD position in a project on "A Formal Analysis of Social Procedures", which is led by Eric Pacuit, they have reverted back to the four year norm. For more details, on the project see: http://ai.stanford.edu/~epacuit/vidi/
