Talking about effective altruism is a constraint, as is talking about mathematics.
One constrains you to a subject with thousands of high-status practitioners and hundreds of students—the other restricts you to a subject with one high-status practitioner and no students.
Whose status ordering are you using? Getting someone who is not a mathematician to TMS is harder; within the Natural Sciences it is possible, and there are O(1) Computer Scientists, philosophers or others. For the historians, classicists or other subjects, mathmos are not high status. In terms of EtG, these groups are valuable—most traders are not quants.
