ADD and ADHD have been the most over diagnosed "disorders" of the 20th and 21st century. A child has a short attention span in school? BAM! DISORDER! MEDICATE THEM! A child doesn't pay attention to certain stuff? BAM! DISORDER! MEDICATE THEM!. A child gets easily excitable about things on a (seemingly) random basic? BAM! DISORDER! MEDICATE THEM!
To anyone "medicated" because of ADHD, I always tell to drop the medication (it does more harm than good) and just enjoy their own quirks.
A bit off the original question, but there you go.
And your qualifications for making suggestions to people's medication?
My grandfather used to use an expression that sticks with me more and more as I get older. Never confuse the confidence of intelligence with the arrogance of ignorance.
You have done far less than the bare minimum of due diligence of educating yourself on a subject before subjecting others to the blather of your opinions.
ADD and ADHD are far, far more complex than having "a short attention span" or "not paying attention" or "being excitable", none of which are even actual symptoms of either disorder. The
actual symptoms are far-reaching and complex and permeate a person's entire cognitive and reasoning systems, to the point of disabling or limiting executive functions.
And no, I hasten to add - knowing exactly what you'll say - that doesn't mean in the slightest that their intelligence is affected. It is not. Extremely bright people and very simple people have had ADD.
My suggestion to you is that you stop philosophizing an actual neurological condition. If you cannot define and describe cognitive functions as compared to executive functions and which set us used for what processes, shut the fuck up about the conditions and disorders affecting them.
Also, stop armchair diagnosing in general.
Dumbed down version: you're not a head doctor nor do you play one on TV, so screw your uninformed opinion.
To the OP: I do not know any INFJs in person (other than myself, and I honestly don't even know her all that well), but I do not have ADD. There are several people very close to me who do, and as the caregiver of one of them, I've done quite a bit of research and learned a lot from doctors about both ADD and ADHD. And autism too, but that's a whole other story.
