I noticed we have cuddle experts who have yet to have their first cuddle. They have it all figured out and often write long essays.
We have marriage experts who are not married. They seem to also believe in their own psychic powers.
We have asexuals, demisexuals, pansexuals ,and more, who believe very strongly that they understand platonic cuddling.
Lots of amateur psychologists too. They aren't troubled by only having a bachelor's degree and no career experience in a related field.
Last, but not least, there are those who take their solitary anecdote and put it forth as data.
What many of the above share is the inexperience of youth, being in their 20s.
Calling it as I see it.
