The NFL has been a leader in the research of human behavior since the 1930s, when it drafted the first rulebook.
But the NFL’s own official playbook, drafted by the league in the 1960s, has not been updated since the late 1970s.
That has left many people who study the game unsure what constitutes sociopathy.
What constitutes sociopathic behavior is difficult to define, particularly because sociopaths can have strong opinions and have complex emotional lives.
“What does it mean to be a sociopaths?
What does it have to do with football?” said psychologist Jonathan Gettman, author of “Sociopaths in the NFL: A Handbook for the Analysis of Sociopaths.”
The NFL’s official playbook is based on the work of neuroscientist James Loftus, who published the first book on sociopathy in 1979.
In the early 1980s, Loftus created a “Sci-Hub,” a computerized database that he said was more accurate than the books he had written and could be used to study the behavior of the average person.
It’s not the only database on sociopaths.
“The books that I have written, I know what the definition is,” Loftus said in an interview.
“So I have an idea of what’s a sociopat.”
Loftus is not alone in his belief that the NFL has created an inaccurate, simplistic definition of sociopathy, said Dr. Steven J. Bielawski, a clinical psychologist who has studied the disorder.
The NFL does not use a specific definition, but Loftus’s books and studies, which are now available online, are a guide for researchers looking to better understand the disorder and the player.
In 2013, the NFL began using the “SOCD” acronym to describe a specific kind of personality disorder, in contrast to the more general “sociopath” or “psychopath.”
This definition is more specific than the one that was developed by Loftus and others.
“In my opinion, it’s much more accurate and scientifically based,” Loftis said in a recent interview.
A study published in 2012 by Loftis and other researchers found that the average NFL player had scores on the Myers-Briggs Type Indicator scale that were higher than the scores for the general population.
The study, published in the Journal of Personality and Social Psychology, looked at 5,876 NFL players between the ages of 23 and 28.
The researchers found players with antisocial tendencies and personality disorders, and those with a history of emotional abuse.
The authors found that most of the players with these personality disorders were male.
“They’re not just an average guy who has an odd personality,” Lofti said.
“These are people with personality disorders and histories of emotional, physical, and sexual abuse.”
According to Loftis, the most commonly seen personality disorder among players was a narcissistic personality disorder.
He called the personality disorder “one of the most significant and pervasive and problematic aspects of sociopathology.”
In recent years, Loftis has also developed the “Affective, Biases, and Disorders in Sociopathy” scale, which measures the degree to which players with a personality disorder have demonstrated “maladaptive, repetitive, or exploitative behavior,” as well as the severity of the disorder, the authors wrote.
The scores are then combined to create the “Personality Disorders Inventory,” which is a more detailed measure of the level of dysfunction in players.
According to the NFL, its definition of antisocial behavior does not include “an unwillingness to consider other people’s needs.”
Loftis says the league has been using this definition for decades.
He said it is not accurate and that the actual scoring of players with sociopath traits is not known.
“A lot of these people are in denial about their personality disorder,” Loftais said.
The term “sophisticated sociopath” was coined in a 1992 article in the journal Psychological Bulletin.
According the article, sociopaths have “high self-esteem, a high sense of entitlement, a lack of empathy, a strong tendency to devalue others, and a highly distorted view of their own moral and social worth.”
They may also have “a strong tendency toward aggressive behavior, particularly against those they perceive as inferior or threatening, and toward a strong sense of power and control.”
According the same article, people with a sociopatha have “an inflated sense of their social standing, particularly when it comes to those they deem as ‘lessers’ or ‘lesser-than.’
They may feel they are owed favors, favors that are often grossly undeserved.”
Lofti also said that the term “sympathetic sociopath,” which he coined in 2013, has become a “silly term” in recent years because people with the disorder are “in denial.”
“Sophisticates have a strong attachment to the concept of empathy,” Loft
