Marshall Goldsmith, author of "What Got You Here Won't Get You There"
http://www.amazon.com/What-Got-Here-Wont-There/dp/1401301304, has stated that personality testing can lead to stereotyping which I'm inclined to agree with. To say my personality type is this and is unchangeable is wrong thinking. This may seem like a “Duh!” moment, but it's surprising how many people talk about personality testing as though people can't change.
Goldsmith commented on a common misconception surrounding the new emphasis we now see being placed in the build-on-your-strengths movement. The idea of building on your strengths is an effective life strategy but not an excuse. He stated:
The build-on-your-strengths idea makes total sense when it’s at the level of the occupation. For example, Tiger Woods should be a golfer, not a stand-up comedian. He’s building on his strengths becoming a golfer and he shouldn’t be a stand-up comedian. On the other hand, I think what happens on the build-on-your-strengths stuff, is people misinterpret it. So they would say, “Well, Tiger Woods is a great driver, so he doesn’t have to worry about putting. He can ignore his putting.” He really cannot ignore his putting. It’s part of his job. If you’re a leader and you’re great at strategy but terrible with people, you can’t just sit there and say, “It doesn’t matter.” It does matter. It all matters. You can’t sit there and ignore part of your job and say “I’m not good at that therefore I have an excuse to ignore it.” All that does is reinforce a useless stereotype. While most advocates of build-on-your-strengths do not encourage that, Goldsmith is right. The idea is often misinterpreted. We must build on our strengths and minimize activities that call upon our weaknesses, but our weaknesses have to be dealt with. And that requires some behavior modification. Too often it can be taken as an excuse to do-your-own-thing and not a position to grow and learn from. We can’t let ourselves fall into the trap of saying, “That’s just the way I am” because it’s hard to change. It may be the way you are, but you can be better. You can grow if you decide to. And as a leader you have an obligation to.
