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…

Dow Industrials Reversal Lower Could Be Double Whammy for Stock Bulls!

Dow Jones Industrial Average “monthly” Chart

The Dow Industrials have spent the past 70 years in a wide rising price channel marked by each (1). And the past 25 years have seen prices test and pull back from the upper end of that channel.

The current bull market cycle has seen stocks rise sharply off the 2009 lows toward the upper end of that channel once more.

In fact, the Dow has been hovering near the topside of that price channel for several months.

But just as the Dow is kissing the top of this channel, it might be creating back-to-back “monthly” bearish ...

Yield Curve Patterns - What To Expect In 2020

Courtesy of Technical Traders

Quite a bit of information can be gleaned from the US Treasury Yield Curve charts.  There are two very interesting components that we identified from the Yield Curve charts below.  First, the bottom in late 2018 was a very important price bottom in the US markets.  That low presented a very deep bottom in the Yield Curve 30Y-10Y chart.  We believe this bottom set up a very dynamic shift in the capital markets that present the current risk factor throughout must of the rest of the world.  Second, this same December 2018 price bottom set up a very unique consolidation pattern on the 10Y-3Y Yield Curve chart.  This pattern has been seen before, in late 1997-1998 and late 2005-2008.

Oil cycle leads the stock cycle

Sure correlation is not causation, but this chart should be known by you.

We all know the world economy was waiting for a pin to prick the 'everything bubble', but no one had any idea of what the pin would look like.

Hence this is why the story of the black swan is so relevant.






There is massive debt behind the record high stock markets, there so much debt the political will required to allow central banks to print trillions to cover losses will likely effect elections. The point is printing money to cover billions is unlikely to upset anyone, however printing trillions will. In 2007 it was billions, in 202X it ...

Fascinating and important to consider, since it is probably one of the reasons why the world aristocracy is pulling its all-out putsch right now… “Trillions will be inherited over the coming decades, further widening the wealth gap,” reports the Los Angeles Times. The beneficiaries aren’t all that young themselves. From 1989 to 2016, U.S. households inherited more than $8.5 trillion. Over that time, the average age of recipients rose by a decade to 51. More ...
