My guess is that due to money being more tight, people want to make sure that they spend it on things that actually matter.

If you are a living organism with the capacity to tell misery or pain just hope that humans don’t find out you can make a product that nothing else an can. If you do end up I’m that situation, you will be turned into a biological machine that receives the minimum amount of necessities met as to not impact production.

Most of these groups are simply “A” and “Everything not A”. Either a number is odd or it is even. Either a place is lit up or it is dark.

That being said there are also some cases in there where there is more than just two categories (like male-female or plant-animal) but we, for the most part, only think about the most important / biggest ones.

All of this probably comes down to the fact that in order to make sense of the world or brain constantly tries to put things into categories to quickly assess what something is or isn’t. And it makes sense that the easiest way to categorize things is by just going “Is this A or B”?
