That's the only sensible answer I have so far. Thank you. I'm gonna answer every paragraph separately.
1) Fortunately, I am on Reddit, and have no obligation to be a paternal figure and to RE-explain the arguments that I took weeks to put together into a nice, beautiful, and musical video. There's only so much I can do for people's education. You wrote a nice, comment, and I will respond to you nicely. I have no time to respond to hate comments who openly state not having listened to my arguments. Perhaps they are suffering, perhaps I am suffering. However, I did not come here insulting people, but I offered a new perspective that they can benefit from.
2) I just want to make people understand that there is nothing behind ADHD that isn't 100% dependent on normative definitions and weaknesses of NHST, and that people shouldn't be passive and say such things as ''I have no friends but it's not my fault because I have a disorder'', while you live unhappily probably because of all the restrictive rules that prevents excitement, originality, and expression (and your inaction towards them). Everyone has the potential to be happy and to find pleasurable activities. But in the end, I'm just here to explain new things, not to tell people how to live.
3) That is a statistical difference, which is a huge weakness in psychiatry. To establish causation (I said that in the vid), you need to demonstrate 1) sensitivity 2) specificity, etc. I don't know exactly what the overlap is, but imagine that the free dopamine overlaps in 80% of cases between controls and ADHDs, it's a difference, but it has so little specificity that you can hardly conclude anything. Besides, it's not even just a lack of dopamine, because that's called Parkinson's. If I'm gonna say that self-esteem is a direct result of height, but only 10% of small people have self esteem problems, that's not a valid causal mechanism. Boring tasks are a vicious circle, the more depressed you are, the less likely you are to do chores. Also for the arousal, it's important to note that it's a spectrum. Some people who are too tolerant of stress have ADHD, and some even develop psychopathy. On the other end, there's autism. So yes it's a difference, but where do you put the threshold for ADHD? I'm not saying that boundaries make everything ''false'', but it's important to remain aware that biology offers neither categories or thresholds in psychiatry. That's great for your grades... but let me know if you are happy in an office in 20 years when the medication wears off. I'm genuinely curious. I seriously doubt that one pill can make you enjoy everything for the rest of your life, but as I said, I'm not here to tell anyone what to do... and I seriously don't know much or care about stimulants. If it works awesome, but then again, it shouldn't be the first answer to hyperactivity, especially in school children.
4) I could cite the references in the description, you are right. FYI my main point is based on an article in Psychological Bulletin. I think it's in the top 3 journals.
I'm very grateful you took the time to watch and comment. Have a great day.
