I bet there are a lot of less visible but stronger correlations to code quality, including incentive structures, programmer time spent to code ratio, quality of tools, quality of documentation, etc.

Swearing in code, however, is much easier to quantify, and of course chosen to chuff up those who think swearing itself is a virtue.

It would be a mistake to draw the conclusion that allowing swearing in code will improve code quality.
