When people gather in a crowd, their collective decision-making can become less intelligent and more prejudiced than individual choices, a phenomenon highlighted by researcher Daniel Richardson. This contrasts with the \"wisdom of crowds,\" which suggests that aggregating independent opinions can yield more accurate results than any single expert. The key difference lies in the independence of judgment; when group members interact and share an identity, the drive for unity often overrides rational decision-making, leading to a sharing of biases rather than information, and ultimately poorer outcomes.
This concept is not new, with experimental psychology demonstrating similar effects for decades. In the 1950s, Solomon Asch's studies showed that individuals frequently adopt the majority view, even when it is clearly incorrect. Similarly, Read Tuddenham found that students would provide obviously wrong answers to simple questions if they believed others had done the same. These studies indicate that social pressure often leads people to conform, even denying their own senses and better judgment.
Richardson's more recent work aims to explore how the presence of others alters cognition and perception, often in real-world settings. He suggests that platforms like the internet, which are often seen as \"information superhighways,\" can in fact act as \"bias superhighways,\" amplifying prejudices and potentially making collective intelligence dumber by facilitating the sharing of biases. While uncomfortable, this conformity effect can be mitigated if even one person expresses an alternative view, empowering others to break from the crowd's consensus.
Ultimately, while there is comfort in numbers, simply going along with the crowd can lead individuals astray. People often underestimate their own tendency to conform, even when there are no explicit penalties for dissenting. Recognizing this capacity for social conformity and actively seeking out diverse perspectives are crucial steps to counteract the \"stupidity of crowds\" and foster better collective decisions.
