Wikipedia says:

Aleatoric uncertainty, aka statistical uncertainty, which is unknowns that differ each time we run the same experiment. For an example of simulating the take-off of an airplane, even if we could exactly control the wind speeds along the run way, if we let 10 planes of the same make start their trajectories would still differ due to fabrication differences. Similarly, if all we knew is that the average wind speed is the same, letting the same plane start 10 times would still yield different trajectories because we do not know the exact wind speed at every point of the runway, only its average. Aleatoric uncertainties are therefore something an experimenter cannot do anything about: they exist, and they cannot be suppressed by more accurate measurements.
Epistemic uncertainty, aka systematic uncertainty, which is due to things we could in principle know but don't in practice. This may be because we have not measured a quantity sufficiently accurately, or because our model neglects certain effects, or because particular data are deliberately hidden.

Therefore, I think nearly all philosophers need to know some QM and neurology.

The question is whether knowing a little QM and neurology is more or less harmful than knowing none at all.

I agree with your first statement.

However, as for your second statement, I would really like an example, because I am not entirely sure what you mean. (I am sincerely requesting examples.)

Unfortunately, I strongly disagree with your third statement. The time it would take to learn QM with sufficient rigor to be interesting could be better spent reading the findings of experimental psychology or learning more mathematics. For the majority of philosophers, their subject matter simply does not overlap with QM in such a way that knowing rigorous QM would help them.

Further, I agree with what paper-machine seemed to imply in their post. A little QM can make a philosopher stupid.

Of course, in certain subjects, knowing QM or neurology should be mandatory.
