You'd think that, but doing research with PhDs at the university made me aware of ethics protocols that almost every researcher has to agree to in order to get a job and get funding. These go beyond protecting life, and informed consent. They discourage studies that could harm "marginalized groups", regardless of any good the findings would provide. For example a study that finds homosexual behavior is to blame for AIDs would be wrong.

So the reality is actually worse. Only common liberal heresies are protected. As we see with the mandatory vaccination and fast-tracked approvals, the whole informed consent and ethics thing can be thrown out the window if the politicians and corporations want it bad enough. Scientists will rarely get funding for taboo research that goes against leftist dogma, but they can violate ethical guidelines if it's determined by the politics of the day to be for the common good.
