The author reflects on the concept of social networks and crowdsourcing which means that people in the aggregate can provide more accurate information than individual experts. She explains that if a large number of people are able to correct one's errors, the results will be overall more reliable than the output of any individual. She cites the Wikipedia and reader reviews on the Web site www.amazon.com. She contends that people need to be aware of the limits of the wisdom of crowds.
