I think being human (as complex, overwhelming and uncertain as it is daily) requires significant intelligence,skill,dedication and creativity that most humans definitely have.
Post like this tend to focused on academic and creative intelligence (though emotional intelligence is also tested just as much as IQ).
According to most tests I've been given since childhood that range from "standardized tests" to more specific ones on IQ, comprehension, problem solving ect. I've scored "above average" mostly (specifically in writing skills).
In my old elementary school I was offered a place in the "gifted youth program" many times but I always refused because all they did was take you to a facility 25 minutes away from the main school. It was all for show to the education officials in my school district, they really didn't challenge the children or give them anything to do for those 3 hours away from the school.
I don't think this means too much beyond that writing, comprehension of complex ideas, creativity and a single-minded devotion to analyzing and solving a problem are my strengths. At the same time, my social IQ only seems sharp when I'm observing someone or a situation, but my charisma is lacking significantly because I'm more introverted.
Mathematics and the sciences tend to be where I'm on par with the 'average' person (which isn't a negative for me, I just don't use those skills in my daily life as often) but science is becoming more and more necessary for me now in college as the foundation of psychology, neurology, anthropology and even philosophy.
I think the only thing that separates me from say.. a graduate in engineering or computer science with a higher IQ is that neither of us will spend as much time on a problem from the other's field of expertise as long as we would on our chosen field of interest/fascination/obsession. It's that diligence, to look at something from multiple angles, and sheer dedication that make someone good at...anything.
This is why I take measured pride in my own unique 'intelligence', but not to the extent that I hold myself as being especially more "remarkable" than anyone else.
'Ordinary' or 'average' people are always the ones that do the most extraordinary things.
PS: Took one of those personality tests at my college, it said I was an "architect" but more introverted.
