You don't need scientific research to know that a good extensible, programmable editor that can become an extension of your mind and hands is going to make you more productive than Notepad.

Sure you don't. You can feel the difference. The problem occurs when people treat their editors as an extension of themselves and can't tell the difference between "not liking you" and "not liking your editor", eventually getting defensive. That's a "cognitive level" I don't want to get myself into.

There will always be flamewars and defensiveness about technology choices. Some people are insecure, some aren't. Not everyone becomes a dick just because they've mastered an editor. My best friend for many years used vim while I used emacs and we used to constantly rib each other about our choices. But we still worked very well together. Maybe you need to work where people don't care what you use to get stuff done as long as it gets done?
