Main assumptions
Lee Ross and fellow psychologist Andrew Ward have outlined three interrelated assumptions, or "tenets," that make up naïve realism. They argue that these assumptions are supported by a long line of thinking in social psychology, along with several empirical studies. According to their model, people:
* Believe that they see the world objectively and without bias.
* Expect that others will come to the same conclusions, so long as they are exposed to the same information and interpret it in a rational manner.
* Assume that others who do not share the same views must be ignorant, irrational, or biased.

From the 1920s through the 1940s, Lewin developed an approach for studying human behavior which he called
field theory. Field theory proposes that a person's behavior is a
function of the person and the environment. Lewin considered a person's psychological environment, or "life space", to be
subjective and thus distinct from physical reality.

However, they are under the illusion that their judgments about the social world are objective. "This attitude, which has been aptly described as naive realism, sees no problem in the fact of perception or knowledge of the surroundings.

and colleagues provided early evidence for a
cognitive bias called the
false consensus effect, which is the tendency for people to overestimate the extent to which others share the same views. This bias has been cited as supporting the first two tenets of naïve realism.
In the study, students were asked whether they would wear a sandwich-board sign, which said "Eat At Joe's" on it, around campus. Then they were asked to indicate whether they thought other students were likely to wear the sign, and what they thought about students who were either willing to wear it or not. The researchers found that students who agreed to wear the sign thought that the majority of students would wear the sign, and they thought that refusing to wear the sign was more revealing of their peers' personal attributes. Conversely, students who declined to wear the sign thought that most other students would also refuse, and that accepting the invitation was more revealing of certain personality traits.

demonstrates that partisans can view neutral events
subjectively according to their own needs and values, and make the assumption that those who interpret the event differently are biased. For a study in 1985, pro-Israeli and pro-Arab students were asked to watch real news coverage on the 1982
Sabra and Shatila massacre

Researchers found that partisans from both sides perceived the coverage as being biased in favor of the opposite viewpoint, and believed that the people in charge of the news program held the ideological views of the opposite side.
"Musical tapping" study
More empirical evidence for naïve realism came from psychologist Elizabeth Newton's "musical tapping study" in 1990. For the study, participants were designated either as "tappers" or as "listeners". The tappers were told to tap out the rhythm of a well-known song, while the "listeners" were asked to try to identify the song. While tappers expected that listeners would guess the tune around 50 percent of the time, the listeners were able to identify it only around 2.5 percent of the time. This provided support for a failure in

. The game was introduced to subjects in one of two ways: it was either referred to as the "Wall Street Game" or as the "Community Game". The researchers found that students in the "Community Game" condition were twice as likely to cooperate, and that it did not seem to make a difference whether students were previously categorized as "cooperators" versus "defectors". This experiment demonstrated that the game's label exerted more power on how the students played the game than the subjects' personality traits. Furthermore, the study showed that the dorm advisors did not make sufficient allowances for
subjective interpretations of the game.
Consequences

students completed a questionnaire about various biases in social judgment. They indicated how susceptible they thought they were to these biases compared to the average student. The researchers found that the participants consistently believed that they were less likely to be biased than their peers. In a follow-up study, students answered questions about their personal attributes (e.g. how considerate they were) compared to those of other students. The majority of students saw themselves as falling above average on most traits, which provided support for a
cognitive bias known as the
better-than-average effect. Next, the students learned that 70 to 80 percent of people fall prey to this bias. When asked about the accuracy of their self-assessments, 63 percent of the students argued that their ratings had been objective, while 13 percent of students indicated they thought their ratings had been too modest.
False polarization
When an individual does not share our views, the third tenet of naïve realism attributes this discrepancy to three possibilities. The individual either has been exposed to a different set of information, is lazy or unable to come to a rational conclusion, or is under a distorting influence such as bias or self-interest.
This gives rise to a phenomenon called false polarization, which involves interpreting others' views as more extreme than they really are, and leads to a perception of greater

differences (see Fig. 1).
People assume that they perceive the issue objectively, carefully considering it from multiple views, while the other side processes information in
top-down fashion.

Kahneman (Eds.), ''Heuristics and Biases: The Psychology of Intuitive Judgment.'' Cambridge, UK: Cambridge University Press. ] For instance, in a study conducted by Robinson et al. in 1996, pro-life and pro-choice partisans greatly overestimated the extremity of the views of the opposite side, and also overestimated the influence of ideology on others in their own group.
Reactive devaluation
The assumption that others' views are more extreme than they are, can create a barrier for conflict resolution. In a sidewalk survey conducted in the 1980s, pedestrians evaluated a nuclear arms' disarmament proposal (Stillinger et al., 1991).

. The researchers found that 90 percent of the participants who thought the proposal was from Reagan supported it, while only 44 percent in the Gorbachev group indicated their support. This provided support for a phenomenon called
reactive devaluation, which involves dismissing a concession from an adversary on the assumption that the concession is either motivated by self-interest or less valuable.
