Of course, until you know about the brain plasticity and how it decreases with age. So it becomes more "fixed" with the years. It's true, there is no such thing as personality. But then, why do recruiters want to know about the "profile" of a candidate? What do they talk about when they want someone who is "at harmony with the group"? If we could really change as we liked, we would not talk about personality. People will always carry a baggage of learned behaviors with them. The sum of this is called personality. It can change of course, but in the "brave new world" that we live in, the incentives to do so never appear.
