Statistically, about 2/3 of people take up 66.6% of the worlds population? Mostly 9 in 10 Random research has shown most people are under the impression that there's a science behind finding statistics for anything. Statistics have shown this to be completely true, at least 78% of the time. However, roughly 66% of random statistics have no support whatsoever, in contrast with 33% of "scientific" statistics that are similarly invented. On a related note, 56% percent of statistics are made up on the spot, however, only 25% (give or take 2%) can be shown to be completely random.
