I have a friend who has been working on a PhD dissertation for over 3 years and he is supposed to be wrapping it up. Unfortunately, his thesis involves a complex model and populating the model with hard-to-obtain data. After having finally gathered all the data and plugged it into the model, he is finding that the theory is more or less non-predictive and does not work. In other words, he had an interesting theory, been having been tested against the data it turns it the theory is wrong.

So, in this situation what do you do? Just write a dissertation that says, "well four years of research shows that this theory is wrong"?
