Let's take salary/income as a basic sample:
Mediam might be as low as 1500€/month.
Mean might be about 5000€/month... thanks to the few who earns/stole/...
about 100k€ or more (like 20m€) per month.
So, according to which one you select, you can say that the
buying-capability is about 5000€/month, or only 1500€/month... not
really the same numbers!

Oh, I see what you're saying - the distribution is actually more like 50%
of people fall into a range of 91-110 (if I remember correctly).

That well could be.

I think so. :-)

More or less my point. :-)

I started rushing through the latter parts because I had no idea how
many questions it had and scored 131.

Just for fun, I tried giving random answers right from the start: The
test ended after just a handful of items, with a score of 78.

It got very very repetitive (yes I figured out how to do the squares and
triangles inside that 2x2 rotating cube, no need to give me 100 questions
using the same idea), I got bored and clicked next repeatedly until the end
and got 125.

I love the way everybody else isn't even trying properly and yet they
manage to get much higher scores than me.
I guess I have to just rationalise it as "Hey, it's an internet IQ test.
It doesn't actually *work* or anything..."
