Is that really so bad? Obviously when extended to race/sexual-orientation/etc it is, but isn't it legitimate to some extent to want to surround yourself with people who share your values?

This is precisely the issue that the social sciences often miss because it's an ethical, not scientific, question.

It is pleasant to live in echo chamber and that is exactly what you would build there. And the result is place where people don't talk about issues and don't solve problems if doing so would go against groupthink. And just like in any echo chamber, consensus will more more toward extreme and people will simultaneously become less and less capable of handling different opinions.

The key phrase you seem to be (intentionally?) missing is "to some extent".

There's a continuum between "echo chamber" and "agreeing about nothing".

You're completely missing the point - if it doesn't get results, they're not going to do it regardless of whether it's morally acceptable or not. Businesses care about results.

[omginternets]

With all due respect (truly!), you are missing the point.

The point is: scientific arguments fail to convince because the issue escapes the scientific domain. The question is not "do we naturally tend to do X, Y or Z", but rather "at what point and to what extent are we ethically obligated to seek out people different from ourselves?"
