IFA.com – http – ifarcs.com – The random walk of stock market prices and the efficient market hypothesis are simulated by physical action of beads hitting a pattern of pins. The Efficient Market Hypothesis says prices are fair. If the expected return of an investment is 1% per month, about half the monthly returns will below and above that average return. So the fair price set at the beginning of each month sets the chance that future returns will be 50% higher and 50% lower than the expected return. The further the returns deviate from the average, the less likely they are to occur. The red bar overlay represents 600 simulated monthly returns of IFA’s Index Portfolio 100. As you can see the distribution of the beads is similar to the index portfolio. When this shape (or distribution) is found to occur with regard to the output of a system (such as monthly returns of capitalism over 50 years), the implications for the system producing it are often profound. Let us see what Francis Galton had to say about it. I know of scarcely anything so apt to impress the imagination as the wonderful form of cosmic order expressed by the law of error. A savage, if he could understand it, would worship it as a god. It reigns with severity in complete self-effacement amidst the wildest confusion. The huger the mob and the greater the anarchy, the more perfect is its sway. Let a large sample of chaotic elements be taken and marshalled in order of their magnitudes, and then, however wildly …

This model is a TERRIBLE model of real-world economic events.
It fails miserably to predict events such as outright multitrillion-dollar fraud by Goldman Sachs, JP Morgan, Citibank, Bank of America, the Fed’s QE1,2,3,…, catastrophic events such as war for oil, war? for water.
Ironic and hypocritical the way economists criticize climate scientists, who have been INFINITELY more accurate with THEIR models of anthropogenic global warming (AGW).

Right Martin . . . the curve is a symbol of balance: 50:50 (statistically 0.5:0.5). But of more relevance here is the Galton Board’s similarity with the Pythagorean Tetractys.? The Pythagoreans’ most important religious symbol was the first three lines of the Galton Board. The fact that it consisted of ten points is consistent with the area under the curve. We see the same symbol today used in ten-pin bowling . . . and hidden in that game: the rest of the story.

From Francis Galton, “I know of scarcely anything so apt to impress the imagination as the wonderful form of cosmic order expressed by the law of error. The huger the mob and the greater the anarchy, the more perfect is its sway. Let? a large sample of chaotic elements be taken and marshalled in order of their magnitudes, and then, however wildly irregular they appeared, an unexpected and most beautiful form of regularity proves to have been present all along.”
