I believe that we need to explore this.
People often say that social sciences cost less, but they cost less because the decision was made to pay students a pittance. However, in reality, there is no reason why a student in the sciences should be paid more than a student in the social sciences and humanities. Earlier, we talked about how students survive when they are not funded. Many students in the social sciences and humanities are not surviving, even in the big universities. So they have to find a job outside the university, which hardly ever happens in the fields of medicine and natural sciences.
In my opinion, it would be interesting to explore the NSERC model, but it would mean increasing the budget of the Social Sciences and Humanities Research Council, the SSHRC.
