A lot of what you're saying is that meritocracy should trump all. As somebody who has spent most of my life making sure people didn't identify me, promote me or put me in positions because of my religion, my name or the colour of my skin, etc., I'm a big believer in meritocracy.
One of the challenges, though, that we've seen in Canada and other parts of the world is that it's much harder to measure merit in systems where access to education, funding and networks has historically been unequal.
How do we overcome that, so that you are in fact getting exactly what you've said, which is the widest diversity of viewpoints such that you are able to do high quality research?
