I do want to point out in addition to Bob Sutton's research, there's Adam Grant's research he writes about in "Give and Take." One of the main takeaways, yes there are a LOT of jerks at the top, and nice people at the bottom, but there are some really pretty amazingly nice people at the top as well, and a large portion of the book is citing studies as to why certain nice people are doormats, and certain nice people can make it past all the "takers." Bob Sutton and Adam Grant's work complement each other nicely.
