Although I pointed it out, I don't think it matters as much as some other things. You don't need to be a rocket scientist to succeed. Give me someone who has a motor and some discipline and can grind it out towards a goal over someone smarter but without those traits.
The lazy and the irresponsible are lacking though.
I agree to a point. I have a high IQ but that is largely based on knowing what number comes next in a sequence or what shape should be the next shape in a sequence (ie seeing patterns). IQ tests totally ignore practical and manual intelligence, not to mention common sense. That said, basic intelligence is commonly lacking. I see so many guys in the gym who can't count the weights on leg press or, very very often, work out iu from mg or ml etc. That's the sort of ignorance that kills people.
Anyway, @abdominal snowman, teachers and standards have gone down imo. My son is intelligent, but to be honest, he is shit at Irish (mandatory subject here, though not spoken - so suck it up). He hardly knows how to count in Irish or common nouns, let alone put a sentence together, yet he gets 4/5 on school report in Irish? (He is 11)
Don't piss on me and tell me it is raining, and don't give our kids shitty teachers who don't understand what they teach and mark shittily.
