The Awesome Science of Chinonomics

Trust is the lifeblood that keeps societies alive, and by extension, what keeps the lives of hundreds of millions of people from harm. Without trust, societies can't exist. You need to trust that your employer will honor your salary, your bank to keep your money safe, and your Angie's list-sourced plumber to not show up with an ax to chop your head off. At the beginning of human existence, morals and reputation within the tribe represented a kind of currency of value, which was used to interact cooperatively and constructively to further the shared goals of survival. Trust, it can be argued, is behind human's success on this planet. As hunter-gatherer groups grew in size, our brains' mental capacities to assimilate and process trust maxed out. After all, keeping a mental score of the number of people that have betrayed you in the tribe reaches a limit (called the  Dunbar number ) fairly quickly. Due to this mental ceiling, humankind demographic growth was constricted

The human brain is a marvelous adaptation. More than that. It's our super weapon. If we measured its capacity in bytes, it would be equivalent to 2.5 petabytes (or 2.5 million Gigabytes). For those who want to measure it in more palatable units, that's roughly 3 million hours of TV shows . No wonder why it's such an energy suck : with only 3% of our body mass, it uses 20% of the body's total blood supply and 25% of its oxygen. Our brain is what made us competitive in nature, what's allowed us to increase our standard of living, and what facilitated the domination of the elements for the exclusive and selfish benefit of our kin. And maybe, too, for the benefit of one or two super lucky chosen species that we like over the rest of the animal kingdom because we happened to breed them to our liking. But before we dominated the planet, natural selection was this randomized process of trial and error in which each species could get better generation after gener
