There are two major faults in this study: 1. They compare only "errors", but don't have any measure of overall document quality. It's certainly the case that it's easier to make mistakes in LaTeX, but I find that people who use LaTeX tend to end up with more professional documents. 2. They compare only on very short documents using very little time. In much the same way anything I'm going to type in 20-30 seconds is better served by Notepad than Word (mostly because Word isn't always even usable in that time window), they're failing to compare LaTeX to Word in the situations where I'd argue that the distinction matters - namely, large, complex document writing. Things with >40 hours of work involved, >100 numbered items, >50 internal references, etc.
