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
An 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.
UK prime minister, David Cameron, promised to hold a referendum on whether Great Britain should remain in the EU, but only on two conditions. The first condition, that Cameron be re-elected as prime minister is iffy enough.
The second condition, that Cameron renegotiate the Lisbon Treaty, I said would never happen. And it won't.
German Chancellor Angela Merkel sealed the fate on that score as Berlin plans to streamline EU but avoid wholesale treaty change. Berlin is drawing up plans for treaty changes to streamline decision-making in the eurozone, while stopping short of any wholesale renegotiation that would allow the UK to repatriate powers from Brussels.
Although Angela Merkel, German chancellor, has expr...
U.S. equity futures traded lower in early pre-market trade following a weaker than expected GDP report from the eurozone for the first quarter.

So, what did the market want today? Nothing it appears. It traded on weak volume and had very little movement. This morning the market hated commodities especially silver, but by days end, the market liked silver, gold and even oil but not the dollar. Why?
Last week the economic reports were tough, with bad misses on more than one occasion. But the market tended to ignore the bad news, probably because money continues to pour into equities from money market funds, long term fixed income, and many struggling foreign economies. On Thursday, investors finally caved to even more bad news from Initial Jobless Claims and weak Housing Starts. Then on Friday, when Michigan Sentiment and Leading Indicators posted large positive surprises, the money came pouring back to generate qui...

Again, not much to add to this market in terms of analysis – nothing matters other than central banks. Last Wednesday/Thursday there were some 9 economic reports, 7 of which were disappointing or could be considered as such and all it got was one rare day down, and then new highs Friday. Markets are up 10 of the past 12 sessions and 17 of 21. Friday's move to 1666 was an exact 1000 point rally from March 2009's 666 bottom. Since this most recent leg of the move has been medium fast rather than a huge spike ala 1999, things are not necessarily overbought on the daily chart but we are seeing extremely rare action on the ...

I am going to share with you how I manage my IRA and the power of reducing your cost basis. My goal each year is a 20% return in my IRA. Sometimes I make it and sometimes I don't, but I believe that all of my success is due to reducing my cost basis. To illustrate the power of reducing your cost basis here are some trades we did last year. These trades are taken from an educational portfolio we ran in a paper-trading account for a little more than a year.

Well, well, well....it is good to know that there are others in the scientific arena who believed that YMI Bioscience's data (cough - Gilead) is a better drug than Incyte's Jakafi. Now, the definitive data are still unknown, but there was enough evidence from a Phase 2 trial to take a small risk for a huge reward. So, let's forget about Apple (AAPL), and do nothing but biotechs from now until Congress passes universal health care coverage for prescriptions....and drive the prices down so that research and development is no longer feasible to conduct in the US. Even Seattle Genetics (SGEN) has been on a tear as of late...
