Well, the worst engineers don't push any code so maybe it looks like they don't think writing more code is productive.

However its been my experience that the average engineer believes this. They often aim to push some amount of code (meaningful or not) every few days or so.

The best engineers I know write a lot of code overall but are more interested in ensuring they build the right thing and are ok with not pushing code for a while if they need more time.

Bad engineers have pretended like more code is more productive. Certain programmer-types will grasp at any straws to maintain their ego.
