If it's genuine, or at least convincing, I would agree.

I've witnessed a few attempts at this which clearly didn't meet that criteria and it was nearly the most off-putting managerial song and dance I've ever witnessed.

I get the impression there's a certain group of people who read lists like these online or in a book somewhere and go about mimicking them without understanding the underlying prerequisites.

Eating the failure and giving the success necessarily requires a total understanding of the actual successes and failures.

Without that, the selfless routine is doing everyone a disservice by hiding the actual problems and quashing further discussion that might reveal them.
