“The Dunning-Kruger effect was proposed by David Dunning and Justin Kruger in 1999. They found that, if people have limited knowledge on a topic, they tend to be extremely confident in what they’re saying and grossly overestimate their competence to discuss it. Conversely, as people gain more knowledge, they become more shy about expressing it. If we apply this theory to social media conversations, the people who know the least will be commenting the most because they’re over-confident. The Dunning-Kruger effect, combined with empathy destruction, could create an environment where those with the least knowledge are the most vocal, yet are unable to comprehend opposing points of view. At the same time, those with the most knowledge are likely to stay silent. Hence we end up with a cesspool of over-confident ignoramuses yelling at each other. Social media in a nutshell, ladies and gentlemen.”
