If you and twenty other people were inside a cave, and were debating on whether it was day time or night time, you could reason through it properly by recounting all the events of the past few hours and how they long must have taken since you entered.
Or you could do the simpler thing - walk outside and look up at the sky.
For some reason, it would be quite likely that human beings would simply be too lazy to take the simplest effort of looking up, and would prefer the mental labour of whether it is likely night or day. Let me explain:
Between 1921 to 1955, it was agreed that human beings had 24 chromosomes. Back when eugenics was popular in Progressive Era America, one Frankenstein-like American scientist chopped off the testicles of two imprisoned black men and one asylum-committed white man, and counted. Wrongly. By 1921, his claim that there are 24 chromosomes was widely accepted.
Immediately afterwards, experiments on human liver cells ceased. Why? Because the scientists counted 23 chromosomes in those cells and concluded they MUST BE doing their work wrong.
Another researcher looked at the number of chromosomes in cells. His students and assistants also looked at the number of chromosomes in cells. They counted 23, but said there had to be 24 - their mind was playing tricks on them and one of the seemingly big chromosomes was probably two chromosomes attached together.
One Indonesian scientist went to work in Sweden and counted 23 chromosomes under a good microscope. He then opened photographs in all books of genetics and biology in that Swedish institute, and saw that where captions said "24", there were still 23.
The Indonesian man somehow managed to convince his older, more experienced Swedish colleagues that there were, in fact, 23 chromosomes. The Swedes agreed. Slowly, so did the Americans. After 34 years of accepting one man's counting error.
So there is no dispute about human inhibition to simply look up. But the question is - why? Why?
Tell me, Mises.Org, WHY?
Evolution. Once you have some answer, move on to the next problem. Many unperfected answers are better than hair-splitting.
