People need to know that results-focused thinking is important in the first place.
Maybe you are overestimating how many people make this effort. For the most part, when you say "solved" most people will take that to mean "my side won" and when your side is for the criminalization of drugs a priori then if screeching and shouting and thinking about kids are what is necessary to get the job done, then that's what will happen. Most people don't do this on purpose, rather the thought never occurs to them to examine why they support a thing, i.e. what their goals are, and whether the measures they endorse to further these alleged goals actually do anything to accomplish them.
Why do people support criminalization of drugs? Do they just think that drugs are really bad and that people shouldn't use them no matter what? Putting aside for a moment whether this belief is justified, does the current regime even manage to reduce drug use? Maybe they just think that drug users are bad people and need to be punished, but I wonder what such people think of enriching drug cartels, which the policies they support tend to do. Then there is the harm reduction cohort, which is the one that I think has finally come around to the fact that criminalization isn't accomplishing that goal, and is why we are starting to see legalization after the destruction of millions of lives.
