Driven toward reward without regard for consequence

This is interesting. However, the conclusion that "individuals with antisocial personality disorder may not be unaware of… consequences… but instead that their intense reward-seeking motivation consumes their attention wholly until they have fulfilled their desire for reward" seems overstated, and only a small piece of the psychopath puzzle.

For a different perspective, that of a financial writer, and an even farther-fetched conclusion, read the second article below. The same data can be interpreted to show that a trader taking on excessive risk is "hopped up on dopamine" so they can’t see negative consequences, making them "kind of a psychopath." Take all this with a grain of salt haloperidol. - Ilene 

Driven toward reward without regard for consequence

Courtesy of TIME, by Tiffany O’Callaghan

TIMEAn overactive dopamine reward system in the brain may help explain why psychopaths pursue rewards without regard for consequences, according to new research published this week in the journal Nature Neuroscience. Previous research has found that individuals who suffer from antisocial personality disorder—often referred to as sociopathology or psychopathology, despite debate over whether these are distinct conditions—lack empathy and fear. Yet this new study, from researchers at Vanderbilt University examines what these individuals may have in excess. According to the study, led by Joshua Buckholtz, a graduate student in psychology at Vanderbilt, individuals with antisocial personality disorder traits show signs of dysfunction in dopamine reward systems—suggesting that, in psychopaths, the drive toward reward can overwhelm all else.

Prior to participating in two different experiments, study subjects completed personality tests to identify presence and severity of psychopathic characteristic—including aggression, lack of empathy, and capacity for manipulation, among other things. Drawing on previous research that has established a strong link between substance abuse and psychopathology, in the first experiment researchers gave participants amphetamine, then used functional Magentic Resonance Imaging (fMRI) brain scans to monitor how dopamine release was affected by the stimulant. In a second experiment, study participants were told that they would be paid for performing a simple task, and researchers conducted brain scans while they completed the tasks.

In both experiments, researchers found that participants who had psychopathic characteristics according to the personality test, were more likely than those without those traits to have greater activity in the nucleus accumbens, the area of the brain associated with dopamine reward processing—whether in response to the chemical stimulant, or the suggestion of monetary reward.

The findings suggest that individuals

On June 15, 1215, King John sat in a field in Runnymede, England, surrounded by angry nobles.

His Barons - the big landowners throughout England - had rebelled and seized London, forcing King John to sign an agreement guaranteeing certain rights to the people of England... and restrictions of his power.

This agreement was called the Magna Carta. And it would become one of the most important documents in hist...

Weekly Market Recap Oct 14, 2018

Courtesy of Blain.

Wednesday and Thursday finally brought some fireworks to a very complacent market.   The S&P 500 had not had a 1% move in 74 days until Wednesday’s drawdown.

Rising yields were nailed as the culprit but months of rallying eventually require some sort of shake out – whatever the catalyst.  Wednesday’s sell off was the worst day for the S&P 500 since February and the worst for the NASDAQ since June 2016.

The market losses are “a reaction from investors finally realizing we are in a higher interest-rate environment, and given the elevated level of stocks, market participants were likely looking for a reason to sell,” said Charlie Ripley, senior investment strategist for Allianz Investment Management. “Higher interest rates typically bring on tighter ...

Vilas Fund Up 55% In Q3; 3Q18 Letter: A Bull Market In Bearish Forecasts

By Jacob Wolinsky. Originally published at ValueWalk.

The Vilas Fund, LP letter for the third quarter ended September 30, 2018; titled, “A Bull Market in Bearish Forecasts.”

Ever since the financial crisis, there has been a huge fascination with predictions of the next “big crash” right around the next corner. Whether it is Greece, Italy, Chinese debt, the “overvalued” stock market, the Shiller Ratio, Puerto Rico, underfunded pensions in Illinois and New Jersey, the Fed (both for QE a few years ago and now for removing QE), rising interest rates, Federal budget deficits, peaking profit margins, etc...

Mapping The Market

Mistakes were Made. (And, Yes, by Me.)

Via Jean-Luc:

Famed investor reflecting on his mistakes:

Mistakes were Made. (And, Yes, by Me.)

One that stands out for me:

Instead of focusing on how value factors in general did in identifying attractive stocks, I rushed to proclaim price-to-sales the winner. That was, until it wasn’t. I guess there’s a reason for the proclamation “The king is dead, long live the king” when a monarchy changes hands. As we continued to update the book, price-to-sales was no longer the “best” single value factor, replaced by others, depending upon the time frames examined. I had also become a lot more sophisticated in my analysis—thanks to criticism of my earlier work—and realized that everything, including factors, moves in and out of favor, depending upon the market environment. I also realized...
