Survey done at IITD, IITB, IITM, IIT KGP and IITK.

Reaction of meritocrats: "That's exactly why they are the top 5 IITs. You can't have quotas for science research and if you want to be in the QS top 200 like these colleges."

Reaction of reservationists: "Aiming for QS rankings cannot override social justice issues. Science research will have to be conducted after quotas are put in place."
You're misrepresenting 'reservationists', which I suppose was the point of your post? Isn't their point that there is an obvious lack of representation at the top, which is an indication of systemic discrimination?

In most professions / corporate careers it is the same for men vs women: does this mean corporate ceo, partner, senior counsel and other career ladders are meritocratic for not letting more women in, or that the cards have been / are still stacked against them?
you are so far left you're almost making arguments the right would make just with different reasoning.
lol- so universities in UK/US who are topping QS dont do diversity hiring? of course they do. Your problem is the indian education system being substandard- dont blame that on the community which has had access to this system for the least amount of time.
They don’t reserve 50% of seats in the US/UK and even affirmative action may be struck by the SCOTUS soon.
They dont because they dont have to. In UK/US, the social minorities are numerical minorities as well, which is absolutely not the case in India.

Moreover, Harvard may not have affirmative action in another year but as far as they do have it, their affirmative actions considerations are far greater than ours. Even though Whites are about 60% of the country, they are far lesser than that in the student body because they allow for greater representation of minorities through affirmative action.

We reserve 50% of the seats but in the other 50% upper castes are far more represented than their population. It is literally simple math that allows you to respect reservation.
I fail to understand what business does a journal like Nature have to comment on the caste equation in top educational institutes in India. Earlier, they have consciously stayed away from social issues saying it does not fall within their 'domain'. Looks like another Western propaganda to undermine India's true scientific potential.

On a side note, most western institutes do not take students from weaker sections in India for PhD programs. As a result, India's PhD programs are mostly staffed by students from weaker sections of the society who have graduated from IITs.
Good observation all round. Yes, Nature should not become like EPW.
Clearly, they are surveying the compositional representation in science fields by surveying the caste diversity in the faculty of the 5 best engineering (a branch of science) colleges in the country. Plus, even if they wish to diversify, why should anyone call them out for that? It is the Editorial Board's decision to move into newer fields for the journal if deemed necessary.
