Research: Human random generator

We asked 600 people to mention any random number between 0-99. Do you think results were random and usable as a random number generator? Unfortunatelly not – some numbers are preferred, some numbers were not mentioned at all.

Favourite numbers: 77, 13, 7, 33, 23, 99, 55
Most unpopular numbers: 20, 49, 61, 91, 93, 94, 95, 96, 97

Here are complete results, the bigger size the higher frequency.


What is your random number? 😉
