A new report shows that President Barack Obama is not a narcissism.
It also points out that he may have been a sociopath, too.
The report, published on Wednesday by the nonprofit think tank the Brookings Institution, found that Obama has exhibited traits that could be considered narcissistic.
It cites a 2015 survey of 3,000 people by the National Opinion Research Center.
The survey showed that 41 percent of respondents said they had a narcissistic personality disorder.
The report did not say how many people were narcissists.
The researchers said that it is not clear whether narcissism is a diagnosable condition or whether it is a trait that could not be diagnosed.
The National Institutes of Health, the nation’s primary research agency on mental health, said in a statement that it does not support the use of the diagnostic term “Narcissistic Personality Disorder.”
The researchers found that nearly one-third of respondents thought Obama was a narcissian, compared with about half of people who said they did not.
The researchers also found that one in five respondents said he was “sociopathic.”
The authors did not identify any other signs of narcissism, such as grandiosity, a tendency to seek attention, or the use in the workplace of a narcissistic style of speech.
The study is part of a larger effort to study the personality and mental health of US presidents.
A few presidents have been diagnosed with narcissistic personality disorders.
The most famous was Ronald Reagan, who was diagnosed with borderline personality disorder in 1980, according to a 2008 book by Dr. John L. Baer, a clinical psychologist and professor of psychiatry at the University of Chicago.
