Similarly, at the next stage of development, there is a correlation between the size and complexity of the social group of a primate species and the size of the cerebral cortex in proportion to body weight.In other words, the grooming, the hierarchies, who's up, who's down, who's alpha, who's beta, how can I still get some if I'm beta, the coalitions and all the rest of that. Right?
Everything. That perspective is essential to understanding your brain. If you were to write a history of humanity in proportion to the amount of time that we have spent at each stage of development, you'd write 200 pages on hunter/gatherer societies.200 pages. You'd have one page for agrarian societies.
And I said, this graph doesn't say anything about how smart someone is. And in fact, this next graph has the exact same data, but it's plotted how large the brain is in proportion to the whole body. So this is brain-body ratio.
And again, tiny, tiny little brains. But in proportion to their body, they're larger than they are than us humans. So it goes to the question, what does it mean to be intelligent?
But actually, that's not the technical definition of exponential growth. Exponential growth is something which grows in proportion to its current size. So the money in your bank account, if you leave it there long enough, it is growing exponentially.
You're getting compound interest. And so the money is growing in proportion to its current size, but I don't think anyone would accuse the money of their bank account, or certainly not in my bank account, of being big or fast.
And I'm going to talk about how to do that now. And as their activity increase in proportion to or in relation to the sense of reward, as that happens,
Elephants, dolphins, and whales have large absolute brain sizes than we do. We're not the animals on earth with the largest brains in proportion to our bodies. There are several animals.
And again, we go back to these experimental types of results which ask the question, if you augmented GDP with these intangible assets, what would you see? And you essentially see a rise over here in intangible assets-- this is shares of investments in proportion to GDP-- and a fall of tangible assets.
Right, their brains are 13% of how much they weight. And so just because someone has a large brain, has a larger brain in proportion to their body, says nothing about their intelligence. We are not the animals on earth with the largest brains.
So in 1838, French scientists proposed a different scaling law. Since metabolism generates heat and that heat is radiated through the surface, metabolic rate or B, should scale in proportion to the surface area, A, instead. This became known as the surface law.
And you don't cover hugely fake news, but in terms of peak fake news, do you think we have reached peak fake news? And actually, I wonder, as the emphasis has been placed on the fake news in recent months, is it in proportion to the scale of the problem in this country? Well, I've got a slightly odd perspective on this.
As a result, the products lose their distinct identity or autonomy." That's the most interesting part for me. He says, "But the record of the Community Chest campaign shows that they give more generously, in proportion to their numbers, to the general charities
