Cass Sunstein Quotes
Groups become more extreme and entrenched in their beliefs and polarized from others when members only exchange information that reinforces their views and filter out all else or never learn of alternatives. Thus they narrow their options, and magnify each other's prejudices and misconceptions. This trend leads to blind spots in decision making and to extreme behavior, even terrorism.
