> It's like best practices for computer security -- always strive to minimize the attack surface. I suspect that's also why some papers are unnecesarely verbose and describe simple things as complicated as possible. Can't criticize something that can't be understood.
Then why submit it for peer review at all?
I also detest simple things made complex, though. In my experience (with has covered electronics, epidemiology and geography) reviewers tend to pick up on obtuse issues in text but miss glaring errors in the math.
