New Scientist Life:

The brain’s power will turn out to derive from data processing within the neuron rather than activity between neuron, suggests University of Cambridge research biologist Brian J. Ford.

“Each individual neuron is itself a computer, and the brain a vast community of microscopic computers… the human brain may be a trillion times more capable than we imagine,” he adds.

Here’s a phenomenon we’ve all noticed: a friend insists they’re right about something, refuses to waver in spite of doubters, and then consults Wikipedia, only to realize that they’re dead wrong.

There’s actual science behind that phenomenon, argues Cornell professor David Dunning. He’s recreated similar experiments in the lab, asking subjects about fictions political figures, for example, or nonexistent cities – and gets much the same results as the late night hosts do. He explains:

“What we find is that people are quite ready to start talking about things they can’t possibly know anything about because we made that thing up in our office just the week before”.

The rationale for the behavior may be pretty sound, when you consider basic human behavior and communication.

“Whenever we’re talking to other people, we just have to assume that whatever they’re asking us is reasonable – because what if we questioned everything that was asked of us? That would make conversation very hard,” Dunning says. “But the other thing that we’re finding is that people don’t necessarily exactly know what they know versus what they don’t know; they infer what they know versus what they don’t know from, let’s say, pre-existing notions they have about themselves.”

In other words, if someone thinks they’re a news junkie, they’re much more likely to think the things they’re saying about people in the news are true. Fancy yourself a politico? You’ll probably say you’ve heard of senators that don’t exist.

Whether this trend to be overconfident is a good or bad thing – well, the jury’s still out.

“In terms of evolution, it’s unclear whether this is a facility that we’ve evolved, or if this turns out to be the problem that evolution hasn’t successfully tackled yet. There is a reason to believe that at times we are going to make mistakes and claim knowledge of things we have no knowledge of. We’re inveterate storytellers, we’re inveterate explainers, we’re inveterate theory inventors. We see something out there in the world and we try to explain why it’s happening.”

Lee Kuan Yew was at helm of the one of the most astonishing economic records of the last century. Singapore owes much of its prosperity to a record of honest and pragmatic government, the legacy of Lee Kuan Yew, who has died aged 91.
