Someone said "if you wouldn't attack yourself in street fight don't do it verbally", but for the sake of good British joke I will say following: So, down-voting my answer is confirming my statement. I do not know much about subject but I confidently claimed 100% effect, therefore confirming what I said :)

It is like that brain melting sentence "If I say that I am lying, am I lying?"

If I claim that Dunning-Kruger Effect is 100% real is it really real? :)

Marry Christmas and Happy Holidays everyone!
