Rides through the middle of town in the pedestrian precinct, along the pavement out of the town centre. And is employed at the council office, so clearly they don't give a shit. Not cool to nick one of their own, you know, and parking tickets are more lucrative.

If there are any laws specifically for monocycles, I expect they will be the same as for tricycles and bicycles.

I used to work in a (fur lined) cube farm. Sometimes there was a whoosh followed by a crump, as someone learning to use a monocyle whizzed past and hit a shoulder-height partition. Separately, before the farm was fully populated, another person used to lay his parachute out on the floor to air, before repacking it. Happy daze.

Pedantically, average is not necessarily the halfway mark. You could have an average where most of the population are above it  ;)

So, you don't think intelligence doesn't follow a Gaussian distribution? You have some reason why it might not have a stable mean, and not follow the central limit theorem? Perhaps you think its more like a Pareto distribution?

I have no idea - I was just making a joke out of being a pedant, and put a smiley on it in an attempt to give the humourless a clue.

I doubt that measured "IQ" is a truly valid quantitative measurement of anything beyond the ability to score on IQ tests.
However, in current psychometry the scores are normalized to a normal (Gaussian) distribution with mean = 100 and standard deviation = 15.
In that distribution, (the median) = (the mean) = (the mode).

We do not know the shape of the g factor distribution, and it might not have a nice normal distribution, although somewhat normal (Gaussian) is considered most likely.

Intelligence test scores are normalized to a Gaussian distribution within the target population, so the fact that any set of IQ test results converges to a normal distribution is expected from the test scoring calibration directly, and does not require the measured aspects of intelligence to have a normal distribution at all.

Principal components analysis done on large enough datasets (IQ-style questions), to uncover the relative g factors of participating humans, does seem to be a valid measurement of something: see e.g. practical validity chapter of the Wikipedia g-factor article for references.

I find the g factor to have a rational basis, and the principal component analysis (assuming sufficiently large number of individual questions) should erase most types of e.g. cultural biases, assuming the medium used (paper, computer, oral, whatever) for the questions is equally familiar to all participants.
