In my experience it tends to be the opposite — I am not a quant (QD) but having worked with a few teams there’s a negative selection for technical expertise. QRs who are good at programming are usually pushed into maintaining infrastructure, datasets, or just tooling for less technical members of their team, who then get to use those tools to further their own alpha generation. Orgs incentivize the final step in making alpha — spend too much time helping others or building reusable research, and your coworkers steal the thunder.

That, or stop helping your coworkers/accommodating them… risky, as a career move. Only seen that work once.
