Anything with a gaussian curve ;)

I meant the highest point is somethink like at 98 points and not totally mirrored sides.

Normally in a gaussian curve the definition is that the highest point is in the center and both sides are the same ;)

Intelligence is commonly described as following a normal distribution. I think you are being nitpicky for the sake of nitpicky.

You free to think what you want ;)

It is a fact that the IQ is constructed. It is not random based.

For example, If we used the Gaussian curve as our guide, we would expect to find an IQ of 160 or above among about one in 31,600 children. In fact, we find an IQ of 160 or above occurring in one in about every 1,125 kids

And yes, I may be nitpicking. I love philosophy after all ;)

Of course you are free to pick one of many other phenomenons.

Radioactive decay
Radioactive decay (also known as nuclear decay or radioactivity) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, gamma ray, or electron in the case of internal conversion. A material containing such unstable nuclei is considered radioactive. Certain highly excited short-lived nuclear states can decay through neutron emission, or more rarely, proton emission.
Radioactive decay is a stochastic (i.e.
