I'm still a little skeptical, simply because what people say and what they do often aren't in complete agreement. There are some people out there that will cynically talk in terms of personal advancement all the time, but when it comes to actions, they tend to do the right thing even though they grumble about how it's not to their advantage. And then there are people who say all the right things, give all the credit to their team, and yet when it comes to actions, they'll do what advances their career over what advances the team.
And of course, it's usually the case that the people who say "all the right things" are usually the ones who tend to do what advances their own career at the expense of the team :)
