Bad behaviour down to genes, not poor parenting, says study
Well, thank goodness we've got that sorted out. You see, we can proceed with this as our "truth," now, to the exclusion of all else. The trouble is, if it's not the truth, then the treatment we prescribe to treat ADHD will fail, and very quickly.
Now, you lazy fuckers: everything is learned, and if you explained stuff better, instead of punishing anything and everything you don't like, you might get further, faster. But you won't, because you're too fucking stupid - and you will indoctrinate your children with the same behaviours that you, and/or others, have shown them.
While I'm at it, I may as well point out why it is that one shouldn't tell a person that they have absolutely no control over their own behaviour. Or, for that matter, why one shouldn't tell others that a person will behave irrationally, irrespective of how one conducts oneself towards that person. It is this: it removes all responsibility from the individual to try other stuff.
In other words: this irrational, fictional person that we're talking about will always have a mind that goes everywhere, and can't concentrate, and is impossible to control, and they will never do what they're told, so they are aberrant, and it's not our fault - the best we can do is feed them some drugs, shunt them out of the way, and ignore them as best we can. Great system. Just make sure that you don't ever question whether or not your approach is wrong, and maybe these aberrants have a point, because it'll fuck your mind.
