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.
 

Bedford and Cavour,

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 Wall Street Journal on the business of high frequency trading:

A costly high-tech arms race in which HFT firms relentlessly compete to shave tiny fractions of a second off data transmission times has also hurt their bottom lines.

Revenue at HFT firms from U.S. equities trading is projected to be just $850 million this year, compared to $7.2 billion in revenue from U.S. stocks trading in 2009, Tabb Group says.

Techniques pioneered by the upstart traders are now common at old-line financial firms. Goldman Sachs, for example, had 600 human traders supporting its cash eq...

The Entire Medical Industry Is About To Change

By The Sovereign Investor. Originally published at ValueWalk.

The doctor straightened and pulled the stethoscope from her ears. “I don’t hear anything on the right side.”

Sometimes silence is a good sign. When it comes to listening to my husband breathing, it’s not.

One quick X-ray later and we discover that his right lung had collapsed. There was also air putting pressure on his left lung.

The fix was easy. The doctor inserted a slender tube into his chest, sucking out the air. His lung reinflated in a matter of minutes.

I caught the doctor later and asked her why this had happened. When the pain started, he’d been watching TV.

She shrugged and admitted that sometimes it was just something that happened to men who are tall and thin.

Of course, the answer to the question of “How do we avoid this?”...

Ukrainian Lawmakers Disclose $45 Million In Bitcoin Holdings

Courtesy of ZeroHedge. View original post here.

As Ukraine's crackdown on corruption continues, three lawmakers from Ukraine’s ruling party revealed this week that they own a combined $45 million in bitcoin, according to a report by RIA Novosti, a Russian foreign news service.

Their holdings came to light during mandatory financial disclosures by members of the Ukrainian parliament, part of an IMF-approved strategy to tamp down corruption in Ukraine. The country's democratic institutions, which were never very robust to begin with, have been further destabilized by...

This would be excellent news for AAPL and GOOG to a lesser extent although not inconsequential:

The App Economy Will Be Worth $6 Trillion in Five Years 

In five years, the app economy will be worth $6.3 trillion, up from $1.3 trillion last year, according to a report released today by app measurement company App Annie. What explains the growth? More people are spending more time and -- crucially -- more money in apps. While on average people aren't downloading many more apps, App Annie expects global app usership to nearly double to 6.3 billion people in the next five years while the time spent in apps will more than double. And, it expects the...
