Please feel free to cite studies with better methodologies! I merely cited what I found on a cursory search. I entirely agree that the methodology of the studies is limiting, however at the moment, the only evidence I've discovered points towards the position you made the following assertion about:
> We all know that you can't provide any evidence to back this up. What is your agenda? Why do you think we are stupid?
The assertion you made is that there was no evidence to support pencilcode's assertion that gender diverse teams perform better. I believe this assertion is false, the top results of a cursory search that I made out of curiosity provided evidence which supported pencilcode's position.
However, I of course agree that two papers is hardly conclusive, so feel free to cite more studies if you want to start wading into the pool of evidence available to us on this topic.
