From the documentation's Frequently Asked Questions...

Why are there a bunch of messages disabled by default?

pylint does have some messages disabled by default, either because they are prone to false positives or that they are opinionated enough for not being included as default messages. But most of the disabled messages are from the Python 3 porting checker, which is disabled by default. It needs special activation with the py3k flag.
