Summary of “but Are Oblivious to Their Weaknesses”

Yet what we see when we administer 360-degree feedback surveys on behalf of these leaders is that the executives with really low scores in one or more areas are often completely unaware of their fatal flaws.
Let us explain what we mean by a “Fatal flaw.” Everyone has weaknesses, but over the course of administering assessments to tens of thousands of leaders, we have found that most of the time that mild weaknesses do not impact a person’s overall effectiveness.
These are weaknesses that are so extreme that they can have a dramatic negative effect on a leader, seriously hampering their contribution to the organization and their career progress.
Why are weaknesses and fatal flaws so hard for us to spot in ourselves? Here’s our theory.
Weaknesses – especially fatal flaws – are the opposite.
Fatal flaws are “Sins of omission.” They’re a result of inaction, of the leader not doing something.
We occasionally do find leaders whose fatal flaws are “Sins of commission” – like a boss with a terrible temper, or an executive who lies – but those people are very rare.
If roughly one-third of leaders have a fatal flaw and you are sitting in a management meeting, look to your right and then to your left.
