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…

Influence, Temptation, And Persuasion

Robert Cialdini’s Influence: The Psychology of Persuasion, has removed any lingering doubt I had that we are reasonable creatures. Cialdini shares so many examples of experiments that at times I literally stood up in disbelief. Here’s a good one:

More compelling evidence for the importance of similarity in determining whether we will imitate another’s behavior comes from scientific research. An especially apt illustration can be found in a study done several years ago by Columbia University psychologists. The researchers placed wallets on the ground in various locations around midtown Manha...

Free Trade Versus "Free Trade"

Courtesy of ZeroHedge. View original post here.

Submitted by Peter Klein via The Mises Institute,

NPR featured an unintentionally funny piece this week on Donald Trump's views toward the EU and free trade. The guest, former US ambassador to the EU Anthony Gardner, rightfully criticized the president's view that "protection will lead to great prosperity and strength," and called for continued global engagement by US companies and consumers. But he revealed, perhaps inadvertently, what politi...

Doc Copper; Time for it to out perform the S&P 500?

Courtesy of Chris Kimble.

Some feel the price action of Copper is important to watch, because it could send important macro messages, about world wide growth or lack of.  Since 2011 Ole “Doc Copper” has been very weak, no question about it. During this weakness, the S&P 500 has continued to move higher. So is the price action of Doc Copper not useful or relevant anymore?

Below looks at ratio of Copper to the S&P 500-

As China Slaps Fees On Bitcoin Trades, Japan Monthly Volumes Soar by 8,900%

Courtesy of Zero Hedge

There is one reason why bitcoin quickly became the darling of HFT and various high speed algo traders operating out of China and the rest of the world: domestic transactions were "frictionless", as there were no fees on buys or sells. Until last night, that is, because as China's three largest bitcoin exchanges, BTCC, Huobi and OkCoin, all said in separate statements on their websites late on Sunday, starting Tuesday they will charge traders a flat fee of 0.2% per transaction. This is only the latest fallout from the recent crackdown on Chinese bitcoin exchanges whose activities have drawn increased scrutiny from the centra...

Secular Stagnation and Pension Crisis?

PSS57 - "There is absolutely no data supporting a premise of demographics. "

Bingo, the vile filth known as "Secular Stagnation" emanated from Larry Summers, and was given an unqualified Fed benediction.  Voila, no real data, no proof, an MSM narrative and repeated URBAN MYTH.  The Flatworld Society has a more promising premise than this intellectual claptrap.

Its another "boogey man" same as the "pension crisis", which will be utilized to take away all forms of private and public pension, and have everybody forced into fee laden 401K/IRA. They will also force Social Security into the same fee laden hole using...

Brownback wants Trump to emulate what he did in Kansas because it worked so well:

Sam Brownback Calls on Donald Trump to Mimic His Kansas Tax Plan

By RICHARD RUBIN and  WILL CONNORS

Sam Brownback, the Kansas governor whose tax cuts brought him political turmoil, recurring budget holes and sparse evidence of economic success, has a message for President-elect Donald Trump: Do what I did.

In 2013, Mr. Brownback set out to create a lean, business-friendly government in his state that other Republicans could replicate. He now faces a $350 million deficit when the Kansas legislature convenes in January and projections of a larger one in 2018. The state’s economy is flat and his party is fractured...
