“Ever wanted to get inside the heads of the world’s top leaders? A new study has attempted to do just that with a test used by NASA astronauts,” Karen Gilchrist reports for CNBC. “Behavioral analytics company Mattersight used the world’s only linguistics-based model to find out what top leaders’ word choices reveal about their personalities.”

“The test, known as the Process Communications Model, was used for almost two decades by NASA to assess the psychological fitness of new recruits,” Gilchrist reports. “Being language-based, it is arguably harder to game than other self-report personality tests.”
