Obviously, it's impossible for everyone to be above average, and it seems people aren't as smart as they like to think they are.
I think it's the other way around. It's just others who aren't as dumb as we think they are.

How smart do you think you are? You can be as modest or arrogant as you like. Honestly, I think I'm above average, if only because I'm around the top percentile in my class.
Being in the top percentage in the class is only valid if all students put equal or similar effort into studying. Some people are smart but they just don't study (perhaps because they're not interested in what school has to offer for them or sth) and get bad grades.
Intelligence is quite more complex than most of us think. There are different aspects of intelligence. For example, top class athletes have Body intelligence (the name may be different, I read about it 5 or more years ago so I may have some semantic deficiency

They learn the correct ways of movement in sports faster than others.
Some people have amazing charisma, can hypnotize others with their personality, even use others for their own purposes, without the others even realizing it.
These are different forms of intelligence. Many people just look at intelligence as the ability to solve logical problems and acquiring knowledge. It's more than that.
If you get good grades in school or can pick a computer apart and put it back together with zero problem but at the same time you're a wimp with no stamina who couldn't kick a football to save his life and you have the charm of an anemic person on morphine then you're academically smart but a physical and social dumbass.

I'm sure you can find out more about it just by searching on google so I'll stop here.
DO YOUR OWN DAMN RESEARCH!!!
So yeah, take this into account as well when determining how intelligent you are.
