Why people say so many stupid things on Twitter

That’s not meant to be an insult, it’s simply a matter of psychology. In his bestselling book Thinking, Fast and Slow, Nobel laureate Daniel Kahneman makes the case that humans utilize two modes of thinking: system 1 and system 2. System 1 is the more primitive of the two, operating “automatically and quickly, with little or no effort and no sense of voluntary control.” On the other hand, system 2 is slow, deliberative, and controlled, used, for example, to fill out a tax form or to check the validity of a complex argument.

It’s apparent which system is most prominently used on social media. Take Twitter, for example, where lots of information arrives lightning fast in brief, 140-character tidbits, and one’s similarly short response is just a few types and a click away. The platform basically goads users into sharing their quickest and most mindless reactions and opinions.
