It is no secret that many random variables of our world are well described by the Gaussian distribution. Today it became interesting to me, but what about artificial random variables generated by consciousness? For example, what will be the type of distribution for the random variable "Your favorite number from 0 to 100"? And what will the “Name any number from 0 to 100?”

It is very interesting to know your opinions, Habrahumans. I would be glad if someone can advise what to read in order to satisfy such an interest, or if someone sticks their nose into the obvious.

In general, it is interesting how the theory of probability and man correlates.

The value of the form "a number named by a person at random", and is not random.

If you ask to guess from 1 to 10, then the maximum will be around 7 = 33%, and 3 somewhere around 20%. 7 and 3 are magic numbers.
So peaks 70, 30 and next, More from 70. also peaks 7 and 3. and 99 with a verbal answer.
When text is selected, 77 and 33 will be peaks.

Consciousness is what it is - the facts about anchoring on the environment are known - the answers will depend on the form of the question, for example, the numbers in the question will be some kind of centers of normal distribution. If there are no specific numbers, then the middle will be the anchor, although some will have their own “favorite numbers” that are out of the general law.
you can look for "cognitive distortions"

for the brain, a native logarithmic scale, after knowing mathematics, the middle also appears.
