"useful" should be replaced with "interesting" because we never know what will turn out to be useful, but by definition, we only look for things that interest us. And I disagree that's a philosophical or political consideration in most cases. It may be in some institutions, but I am sure most scientists will circumvent any restrictions imposed by their institutions in order to actually study what they themselves find interesting, even if under the covers of what their institutions want them to.

As a tangent: even if you're correct that what scientists decide or are allowed to research is mostly political, the facts they find are not, at least if the scientific method is being used properly. Facts are never racist. Facts do not have opinions. And science should look for true facts, not opinions. Hence, even if your focus is on things you find political, the scientific facts and hypothesis you end up with must not be.

All I can say is (－‸ლ)
