> In the short term, he writes, there are clearly challenges, but over the long haul, he argues that diversity has a range of benefits for a society, and that the fragmentation and distrust can be overcome. It’s not an easy process, but in the end it’s “well worth the effort.”
“well worth the effort”. That's pretty subjective. I'm sure many would like to avoid "fragmentation and distrust" in the first place.
> One study isn't enough by itself.
There are many similar studies:
"A higher degree of ethnic diversity is associated with a higher incidence of civil conflict" - https://www.cgdev.org/doc/events/02.09.07/Matuszeski-JMP.pdf
I mean, this stuff is intuitive for anybody with a sense of history.
To be clear I'm not arguing against diversity per se. I raise these points to encourage us (as a society) to discuss - and not emote - these issues honestly.
