Clinging to the Wreckage of Old Ideas

The problem of confirmation bias – the tendency of people to seek evidence confirming an already held opinion and to avoid looking for that which might upset their carefully constructed mental models has attracted a lot of attention from researchers. It occurs across all domains of human endeavour and triggers all sorts of implausible behaviour, yet investors and institutions remain in its thrall.

We find examples in law courts and doctor’s surgeries, in scientist’s laboratories and the lairs of legislators. So we shouldn’t be surprised to find it coursing through the veins of economists and investors, colouring their every thought and structuring their every idea. Of course a rational market participant, faced with a theory built on a crumbling cornerstone will abandon their ideas and look for some new ones. As you’d expect, therefore, we do no such thing, clinging irrationally to the wreckage of our dreams as they collapse around us.

Disconfirming Science

Science is perhaps the area in which we might expect confirmation bias to be least effective. After all, the processes of science are built around the institutionalisation of disconfirmation. New ideas have to run the gamut of envious colleagues who generally hate nothing more than a smart ass and take great pleasure in proving them wrong. Despite this scientists have generally proven remarkably reluctant to give up discredited theories. Indeed science has often proceeded for decades on the basis of ideas that could easily have been disconfirmed had anyone been sufficiently motivated to do so.

So, for instance, the idea that the universe is stable and unchanging was held way into the twentieth century despite the fact that Newton’s laws of gravitation implied something different. To be precise, they suggested that unless the universe was actually expanding gravity should be causing all the bits of matter in the cosmos to hurtle together towards a central point in a manner calculated to render discussions of globalisation, polar bear populations and national debt levels redundant. Yet when Einstein’s theories also predicted an expanding universe he simply made up a special constant, which he later had to ruefully remove, to stop this unwanted behaviour so ingrained was the…

The idea of scientists tinkering with the genes of babies was once the provenance of science fiction, but now it’s apparently entered the realm of reality: On Nov. 26, Chinese scientist He Jiankui reported the historic live births of ...

A new study has revealed that high levels of microplastics have been detected in some of the most remote regions of the world.

The discovery, published in the journal Science Advances, is the first international study on microplastics in snow, conducted by the Alfred Wegener Institute in Germany.

Melanie Bergmann, the lead scientist, and her team of researchers found microplastics from the Alps to the Arctic contained high levels of the plastic fragment, raises questions about the environmental and health implications of potential exposure to airborne plastics....

Long Term Stock Market Chart Perspective

Courtesy of Lee Adler

After a big day like yesterday, I like to get a little long term stock market chart perspective. (Yes, this stilted verbiage is for search engine optimization ).

We do that with a monthly bar chart, which I update when relevant in Lee Adler’s Technical Trader. That’s in addition to the regular daily bar/cycle charts covering the past year, and a weekly cycle chart covering the past 4 years.

I wrote on July 14, in reference to the price and indicator patterns on the weekly chart:

The market has overshot a 3-4 year cycle projection in terms of both price and time. There are no long term projections. A 4 year cycle high is ideally due now. A 4 ye...

Today's news from the US IRS has been blamed for the recent price slump, yet the bitcoin fractal like the gold fractal suggest the market players have set bitcoin up for a slump to $9000 USD long before the IRS news hit the wire.

Global Central Banks Move To Keep The Party Rolling - Part III

Courtesy of Technical Traders

This section of our multi-part article regarding current and past central bank actions, we are going to attempt to look at key elements of the past and present to highlight what we believe may turn out to be an incredible “setup” in the global markets. 

This setup is almost like a complex chess game where two skilled players battle for control and near the end of the game, one player is left with the King, a Rook, and a Pawn while the other player has a dramatic advantage with stronger chess pieces.  Yet, as the game continues, the weaker player is able to remove one or two of the stronger players key pieces and move his pawn to his opponent’s side to r...

New Zealand Becomes 1st Country To Legalize Payment Of Salaries In Crypto

Courtesy of ZeroHedge View original post here.

Bitcoin and other cryptocurrencies have been on a persistent upswing this year, but they're still pretty volatile. But during a time when even some of the most developed economies in the word are watching their currencies bounce around like the Argentine peso (just take a look at a six-month chart for GBPUSD), New Zealand has decided to take the plunge and become the first country to legalize payment in bitcoin, the FT reports.

The ruling by New Zealand’s tax authority allows salaries and wages to b...

Despacito - How to Make Money the Old-Fashioned Way - SLOWLY!

Are you ready to retire?  

For most people, the purpose of investing is to build up enough wealth to allow you to retire.  In general, that's usually enough money to reliably generate a year's worth of your average income, each year into your retirement so that that, plus you Social Security, should be enough to pay your bills without having to draw down on your principle.

Unfortunately, as the last decade has shown us, we can't count on bonds to pay us more than 3% and the average return from the stock market over the past 20 years has been erratic - to say the least - with 4 negative years (2000, 2001, 2002 and 2008) and 14 positives, though mostly in the 10% range on the positives.  A string of losses like we had from 2000-02 could easily wipe out a decades worth of gains.

Still, the stock market has been better over the last 10 (7%) an...
