Other answers I've considered:

o) Simpler universes are more likely, but complicated universes vastly outnumber simple ones. It's rare to be at the mode, even though the mode is the most common place to be.

p) Beings in simple universes don't ask this question because their universe is simple. We are asking this question, therefore we are not in a simple universe.

2') You don't spend time pondering questions you can quickly answer. If you discover yourself thinking about a philosophy problem, you should expect to be on the stupider end of entities capable of thinking about that problem.
