Personal experience and reading points to the opposite conclusion. Trivia: amongst successful actors a disproportionate number of them had parents who had jobs that caused the family to move around a lot (traveling salesmen and the like). Out of the people I've met, those who were moving around a lot as kids had a different quality in my eyes. They also often continued moving around in later life. When you grow up in a single environment you find it harder to differentiate what is a feature of this local culture, and what is a feature of the "wider world", because you're stuck with only one data point.
