Laplace’s Hammer: The End of Economics

Laplace’s Hammer: The End of Economics

Courtesy of Tim at The Psy-Fi Blog 

Clever Man, Stupid Idea

Simon-Pierre LaplaceSimon-Pierre Laplace was a Very Clever Man who did many Very Clever Things. Unfortunately, like many clever men, having got hold of a Brilliant Idea he was rather inclined to go off and use it on everything in sight, which led to a number of Very Odd Conclusions. In fact as far as science goes, he may well have been the original man with a hammer; taking aim at every problem as though it was a nail.

As is the way of these things economists got hold of Laplace’s ideas, converted them to their own and started developing delicate and intricate webs of theories and practices. Unfortunately, over the succeeding three hundred years they’ve failed to keep up with advances in physics and biology, rather leaving economists as the only believers in an approach that suggests we have no free will, a position from which they’re having to be dug out and defused, one unexploded theorist at a time.

Newton’s Error

When Isaac Newton published his theory of gravity he knew it contained a serious flaw; his equations didn’t exactly match what was observed. He reckoned, correctly, that the differences between his theory and the observations were down to the gravitational effect on the planets of other planets – so called perturbations, which he didn’t know how to mathematically model. He said:

“But to consider simultaneously all these causes of motion and to define these motions by exact laws admitting of easy calculation exceeds, if I am not mistaken, the force of any human mind.”

And, of course, he was mistaken. The force of Laplace’s mind successfully solved the problem. Having achieved this, though, Laplace went a stage further. Because he could exactly calculate the position of any planet he could compare this with the results of observations from astronomers. What he discovered changed human history.

Observer Bias

It turned out that observers made errors, but they made them in a particular way – their observations fell about the actual position of the planet in a very distinctive pattern. This pattern, of course, was the ultra-familiar Bell curve or normal distribution. Laplace realised that human error was statistically quantifiable and, therefore, could be effectively eliminated from the data. This…

A Two-State Solution... For The West?

Courtesy of ZeroHedge. View original post here.

Submitted by Erico Matias Tavares via Sinclair & Co.,

There's a cold war raging.

No, not the one between the US and Russia. That’s old news.

We're talking about the NEW cold war: the one for the soul of the West.

On one corner we have the globalists, basically political and financial elites who after the disasters of World War II decided that eliminating borders was the way to ensure a peaceful future. Increasingly diverse (multicultural) societies would now be governed by suprana...

Proudly Permabullish

Maybe Joshua Brown's quite period is over? He did at least emerge from his vacation to post Proudly Permabullish, which is a reminder to look at the stock market between reading depressing news articles from me. (5-year S&P 500 chart from Yahoo.)

Why Facts Don't Change Our Minds

Good article about facts and why we reject them:

WHY FACTS DON’T CHANGE OUR MINDS

New discoveries about the human mind show the limitations of reason.

By Elizabeth Kolbert

In “Denying to the Grave: Why We Ignore the Facts That Will Save Us” (Oxford), Jack Gorman, a psychiatrist, and his daughter, Sara Gorman, a public-health specialist, probe the gap between what science tells us and what we tell ourselves. Their concern is with those persistent beliefs which are not just demonstrably false but also potentially deadly, like the conviction that vaccines are hazardous. Of course, what’s hazardous is not being vaccinated; that’s why vaccines were created in the first place. “Immunization is one of the triumphs of modern medicine,” the Gormans no...

The Manchurian President

As the Trump presidency unravels, unraveling the country along with it, there is no real political antecedent, no lessons from American history on which to draw and provide guidance. We are in entirely uncharted waters.

But there is an antecedent in our popular culture that provides a prism through which to view the contemporary calamity, especially the alleged collusion between Trump’s henchmen and Russian intelligence to deny Hillary Clinton the presidency. I am not the first observer who has ...

Good Recovery

Courtesy of Declan.

In early morning action it was a clear swing to sellers after yesterday's non-event. However, buyers came back and were able to make a good chunk of these losses into today's close.

Large Caps remained the most attractive as defensive stocks often are during times of doubt. The S&P registered higher volume accumulation as intraday action proved to be relatively tight.

The Nasdaq suffered larger losses, but there was no distribution to go with it. Technicals were relatively immune to today's action.
