While we are caveatating...
- Fallacy of assigning causes to the observed coincidences (false correlation).
- Sample size problems even when it looks like there aren't any.
- Lumping incommensurables together to create a decently sized sample set.
- Selection of data by unidentified causes.

In some agenda-driven studies (for instance, funded to provide a particular result) outliers or data that is "obviously bad" are eliminated. This has the result of sharpening a peak (reducing standard deviation), or even creating a peak where none previously existed. In extreme cases researchers might ignore a bimodal distribution. Fortunately we are all too smart to fall into any of those blunders.

That's correct, and it should be mentioned in the Limitations section. However, it should also be noted the study compares the TECHWR-L posts with a number of published studies on gender and communication. Those studies treat gender as binary.

Another caveat is that gender can be non-binary.
