For me its a mix. I've worked at startup that are built apon the core idea of they Y because the CEO did t like there stiff working environment of there last job. Reality is though your hardest workers do great under theory Y. However, most people need theory X or they will just squat and take advantage of the lax atmosphere.

The Wikipedia article actually touches on this:

> For McGregor, Theory X and Theory Y are not opposite ends of the same continuum, but rather two different continua in themselves. In order to achieve the most efficient production, a combination of both theories may be appropriate.

This matches my own experiences in that I tend to default to Theory Y but will flex into Theory X depending on the circumstances.
