I just mentioned about Bob Sutton's excellent blog site. Well, it turns out that he and Jeffrey Pfeffer have a shared site on Evidence-Based Management (based on their book, Hard Facts, Dangerous Half-Truths, and Total Nonsense). In fact, that site also links to Sutton's blog.
There are a number of compelling studies there. I assure you, after seeing their material, you will never look at management the same way. The site also lists the 5 Principles of Evidence-Based Management (EBM):
1) Face the hard facts, and build a culture in which people are encouraged to tell the truth, even if it is unpleasant
2) Be committed to "fact based" decision making -- which means being committed to getting the best evidence and using it to guide actions
3) Treat your organization as an unfinished prototype -- encourage experimentation and learning by doing
4) Look for the risks and drawbacks in what people recommend -- even the best medicine has side effects
5) Avoid basing decisions on untested but strongly held beliefs, what you have done in the past, or on uncritical "benchmarking" of what winners do
Here's the link. I encourage you to visit it often for true leadership enlightenment.
