In Roughtype:  A look at a study that generates a measure called NFC, or 'need for cognition', which is ' ... "a recognized indicator for deep or shallow thinking." People who like to challenge their minds have high NFC, while those who avoid deep thinking have low NFC. Whereas, according to the authors, "high NFC individuals possess an intrinsic motivation to think, having a natural motivation to seek knowledge," those with low NFC don't like to grapple with complexity and tend to content themselves with superficial assessments ... '.    The study looks at how users of social networking are classified with this measure.   The measure itself was new to me.
