I have seen it quoted in various sources (e.g. [this article in Forbes][1]) that, in some way or another, people tend to unconsciously recruit people 'like themselves'. This can mean culturally, physically, having similar background, being from a similar part of the world or other such things depending on the context.

Are there studies which show that, either consciously or unconsciously, people recruit people 'like themselves' in the above or related ways?
