  • It bothers me that no one acknowledged that this can still be logically true. Of course if most people’s ADHD goes away in childhood then it doesn’t really logically mean anything to ask “most people you know with ADHD” because by definition, you will only be asking the subset of people for whom that isn’t true.

    You can’t really survey the people for whom ADHD went away in childhood by asking all the people you know with ADHD because the people who would confirm the psychologist’s claim are not going to be included in that survey.


  • The F sound is usually a labialdental fricative in English. So you are putting your bottom lip on your teeth and letting some air go by to make the F sound.

    English has bilabial plosives where you touch both lips together and let air stop for a moment which makes the P or B sounds.

    English doesn’t have a bilabial fricative so you might be doing this in your dialect and it doesn’t stand out to anyone because it doesn’t otherwise have a phonetic meaning. But, interestingly, in other languages a bilabial fricative has distinct meaning from a labial dental fricative. I believe I’ve read that in Japanese the “F” in “Mount Fuji” is actually a bilabial fricative and not the normal F that English speakers use.
