Neither. I don't make them often, and I do work in quite shared codebases - one of them had over 1000 contributors. I won't pretend I'm a better developer, I surely make other classes of mistakes, usually it's "I didn't consider the user scenario where this file didn't exist or the error path when this file has invalid contents should really raise a better exception than a generic stacktrace".
