That's one way to look at it. When you put a bunch of smart people together on a team they all tend to think they're right and they can get very passionate, even when they don't have any data or measurements to back up their opinions. A little humility and time spent adapting to the environment, team, and code base can go a long way. Anecdotally my experience is that most programmers react to almost all code they didn't write as if it was crap. The more code they have to read and understand the more likely they are to complain about the quality of the code and the overall design of the system. Imagine someone looking at a photo of your house and telling you a hundred things wrong with it, without stepping foot inside or spending some time living there.
