It does affect young and old, but not equally. There is definitely a strong bias towards the young, which is only overcome with the wisdom of age.

Not true, while the young have "stupidity" from lack of experience, the old have "stupidity" without any excuses. And I've met plenty of people 50+ that have made me think, " I have no idea how this fucktard made it this far."

It is true, because even the 50+ fucktard is wiser and more knowledgeable at 50 than he was at 20 when he thought he new everything.

I´ve met plenty of 20+ that have far more knowledge then some of the 40+... and also vice-versa, u cant be that generalist...

OK. Go back to my original comment. I did not put the point across properly in my responses.

All 20 year olds think they know everything. Those exact same 20 year olds when they get older and have learnt a lot more and are a lot wiser will realise that they dont know everything, like they thought they did as 20 year olds . Obviously there are exceptions to the rule who will always think they know everything, but I guess I will just put that down to low IQ.
