Pluralistic ignorance

• 1. Defining Collective Illusions

  ›

  In 1924, Floyd Allport observed a society that conformed to social norms even when individuals did not personally agree with them. This observation laid the groundwork for understanding how people mistakenly believe others hold opinions different from their own. Pluralistic ignorance describes a situation where private beliefs diverge sharply from perceived public norms. Many group members go along with views they do not actually hold because they incorrectly assume most others support those views. A minority position can be wrongly seen as the majority, or a majority view can be mistaken for a fringe opinion. Individuals may fear backlash if they express true beliefs that seem to differ from societal expectations. Social inhibition and embarrassment often drive these collective illusions. The phenomenon encompasses cases where a false perception of consensus prevents authentic expression.

  Floyd Allport first discussed literal attitude behavior inconsistency in 1924 while studying Syracuse University students. His 1931 book Students Attitudes: A Report of the Syracuse University Research Study co-written with Daniel Katz introduced the term pluralistic ignorance for the first time. Allport initially analyzed this strictly at the individual level rather than expanding it to shared cognition. He strongly disagreed with involving concepts like collective cognitive activity impacting overall group goals. Later researchers including Todd Rose argued for interchangeability between pluralistic ignorance and collective illusions. Sociologists and public-opinion researchers eventually conducted heavy work on the concept beyond social psychology labs. Sargent and Newman acknowledged individual aspects but argued they were insufficient without group-level analysis. They defined pluralistic ignorance as a group-level phenomenon where individuals mistakenly believe others' cognitions differ systematically from their own regardless of how misperception arises. This shift reflected laboratory experiments being considered insufficient for studying inconsistencies between attitudes and norms.

  Prentice and Miller examined individuals beliefs about alcohol use and their estimates of peers attitudes during a semester study. Men showed private attitudes shifting toward perceived norms consistent with cognitive dissonance while women showed no comparable shift. Students believed others comfort with drinking was significantly higher than their own even though actual comfort levels were similar. Perceived deviance from the alcohol-use norm correlated with measures of campus alienation despite the deviance being only perceived. Additional research found pluralistic ignorance among both those who indulge and those who abstain from vices like gambling or smoking. Examples include vegetarian lifestyles illustrating that underlying social network structures create multiple pathways for emergence. The pattern characteristic of pluralistic ignorance shows feelings of isolation linked to discrepancies between individual beliefs and perceived group beliefs. Overall the study indicated students underestimated peer discomfort with drinking practices while overestimating public acceptance.

  Pluralistic ignorance has been cited as exacerbating support for racial segregation in the United States throughout history. Many opposed the Communist Party of the Soviet Union but assumed others supported it so most people remained afraid to voice opposition. A 2020 Nature Communications survey of 6,119 representatively sampled Americans found 66-80% supported major climate-mitigation policies yet estimated only 37-43% support existed. Respondents in every state and demographic group underestimated support by at least 20 percentage points. Tulip mania of 1634 serves as an example where investors pursued unique collections of spring-flowering bulbs causing prices to rise rapidly due to collective illusion. Young married men in Saudi Arabia privately support women working outside home but substantially underestimate how widely other similar men share that view. When informed of high support levels these men became more likely to help their wives obtain jobs. Pollution-intensive industries contribute to underestimation of public support for climate solutions in countries like the U.S. where support is actually high.

  The conservative lag refers to a change in attitude not followed by a change in behavior and remains the most common cause. The civil rights movement illustrates this when White American private opinions shifted toward African Americans long before social norms changed. A society perception tends to lag behind actual changes in people's private beliefs and values according to researchers. Liberal leap describes a change in behavior without a corresponding change in attitude often associated with revolutions or polarizing events. The sexual revolution in United States during the 1960s and 1970s brought changes in public behavior while personal attitudes remained consistent. Social identities focus on relationship between person's identity and behavior in social settings where individuals conform to traditional ideals. Children choosing toys and activities associated with biological gender even when interested in alternatives demonstrates this alignment issue. These three structural causes generate collective illusions through different mechanisms of human interaction and group dynamics.

• 6. Consequences For Group Dynamics

  A woman sitting on street receiving no assistance because passersby infer from others inaction that help is unnecessary illustrates the bystander effect. Pluralistic ignorance has been described as roadblock to collective action on public issues such as climate change and COVID-19 pandemic. Groupthink occurs when small cohesive groups make poor decisions due to illusion of unanimity where individual believes they are only dissenter. Individuals may feel embittered and suspicious of those around them when their attitude appears to conflict with perceived majority opinion. This can motivate speaking out against perceived majority view or withdrawing entirely from group participation. More commonly individuals conform in speech and behavior potentially changing personal convictions to align with what they inaccurately perceive as majority opinion. Rapid growth of far-right parties in recent years has also been proposed as consequence stemming from these misperceptions about consensus.
