" For antisocial personality disorder? For obesity and addiction?" If we have a hypothetical scheme to find out all drugs that can be found, and see that the cure for those is not there, that is as a conclusive contribution into finding cure to those ailments as finding a cure.

As the unknown part shrinks, one does not need to spend energy in stumbling there and concentrate on other areas, finally reaching a solution (if a solution can be found).
