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

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

Illinois and Connecticut Face Pension Collapse

By insidesources. Originally published at ValueWalk.

It’s shocking to see the budget horror stories coming out of two of the nation’s leading states. Illinois and Connecticut are in fiscal freefall, and their leaders are taking the exact wrong approach in their misguided efforts to turn things around. If they were smart, they would look to the example of states like Florida to discover how to weather fiscal storms.

Illinois faces a staggering budget gap of close to $10 billion, a crisis worsened by a state pension program funded at just 37 percent and credit downgrades that leave th...

"If The VIX Goes Bananas", Morgan Stanley Shows What It Would Look Like

From Chris Metli of Morgan Stanley

It’s easy to become numb to the low volatility environment and the risks it presents.  While trying to pick a trough in vol has been a fool’s errand, focusing on the risks resulting from vol being so low is not.  Low volatility has produced a regime where the risks are asymmetric and negatively convex, so being prepared for an unwind is critical.  This is not a call that vol is about to spike, but you need a plan if it does.

This note details how a short vol unwind might develop. A violent rise in volatility c...

Tech Gaining Momentum. Small Caps Recover.

Courtesy of Declan.

Tech markets continued the good work from Friday as buyers continued to bid up the Nasdaq and Nasdaq 100. Large Caps posted small losses but this was more about attention elsewhere than any Large Cap specifics.

The Nasdaq experienced a mini-breakout from the consolidation over the last 3 days (traders on the hourly time frame may find some joy here) which keeps the index on course to test larger upper channel resistance. Technicals are net bullish but its relative performance against peer indices which is doing particularly well; Large Caps in particular.

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...
