In contrast to former Microsoft chief Steven Ballmer’s belief that putting data into the hands of citizens will help democracy, a new book – The Knowledge Illusion – argues that more individual knowledge isn’t going to help.
According to Sloman (a professor at Brown and editor of the journal Cognition) and Fernbach (a professor at the University of Colorado’s Leeds School of Business), providing people with more and better information is unlikely to improve matters. Scientists hope to dispel antiscience prejudices by better science education, and pundits hope to sway public opinion on issues like Obamacare or global warming by presenting the public with accurate facts and expert reports.
Such hopes are grounded in a misunderstanding of how humans actually think. Most of our views are shaped by communal groupthink rather than individual rationality, and we cling to these views because of group loyalty. Bombarding people with facts and exposing their individual ignorance is likely to backfire. Most people don’t like too many facts, and they certainly don’t like to feel stupid. If you think that you can convince Donald Trump of the truth of global warming by presenting him with the relevant facts — think again.
