Unfortunately the more complex the work the more difficult it is to peer-review it. Most peer reviewers don't want to look stupid and so there is a higher chance that they'll give the thumbs up rather than question the underlying work. This leads to strong selection for presentation styles that obfuscate research. The more people who can actually understand what you're doing the more people who will be able to challenge you if you are wrong.
