The introspection illusion is a cognitive illusion

A cognitive bias is a pattern of deviation in judgment that occurs in particular situations. Implicit in the concept of a "pattern of deviation" is a standard of comparison; this may be the judgment of people outside those particular situations, or may be a set of independently verifiable...

The illusion has been examined in psychological experiments, and suggested as a basis for biases in how people compare themselves to others. These experiments have been interpreted as suggesting that, rather than offering direct access to the processes underlying mental states, introspection

, much as people indirectly infer others' mental states from their behavior.

When people mistake unreliable introspection for genuine self-knowledge, the result can be an illusion of superiority

 over other people. For example each person thinks they are less biased and less conformist than the rest of the group. Even when experimental subjects are provided with reports of other subjects' introspections, in as detailed a form as possible, they still rate those other introspections as unreliable while treating their own as reliable. Although the hypothesis of an introspection illusion informs some psychological research, the existing evidence is arguably inadequate to decide how reliable introspection is in normal circumstances.

Components

The term "introspection illusion" was coined by Emily Pronin of Princeton University

. Pronin describes the illusion as having four components:
  1. People give a strong weighting to introspective evidence when assessing themselves
  2. They do not give such a strong weight when assessing others
  3. People disregard their own behavior when assessing themselves (but not others)
  4. Own introspections are more highly weighted than others. It is not just that people lack access to each other's introspections: they regard only their own as reliable.

Unreliability of introspection

A 1977 paper by psychologists Richard Nisbett and Timothy D. Wilson challenged the directness and reliability of introspection, thereby becoming one of the most cited papers in the science of consciousness. Nisbett and Wilson reported on experiments in which subjects verbally explained why they had a particular preference, or how they arrived at a particular idea. On the basis of these studies and existing attribution

 research, they concluded that reports on mental processes are confabulated. They wrote that subjects had, "little or no introspective access to higher order cognitive processes". They distinguished between mental contents (such as feelings) and mental processes, arguing that while introspection gives us access to contents, processes remain hidden.
Although some other experimental work followed from the Nisbett and Wilson paper, difficulties with testing the hypothesis of introspective access meant that research on the topic generally stagnated. A ten-year-anniversary review of the paper raised several objections, questioning the idea of "process" they had used and arguing that unambiguous tests of introspective access are hard to achieve.

Updating the theory in 2002, Wilson admitted that the 1977 claims had been too far-reaching. He instead relied on the theory that the adaptive unconscious

does much of the moment-to-moment work of perception and behavior. When people are asked to report on their mental processes, they cannot access this unconscious activity. However, rather than acknowledge their lack of insight, they confabulate a plausible explanation, being in effect "unaware of their unawareness".

. That is, a person may not have noticed the real reasons for their behavior, even when trying to provide explanations. The result is an explanation that mostly just makes themselves feel better. An example might be a man who discriminates against homosexuals because he is embarrassed that he himself is attracted to other men. He may not admit this to himself - instead claiming his prejudice is because he believes homosexuals are "not natural" in some vague sense.

A study conducted by philosophy professor Eric Schwitzgebel and psychology professor Russell T. Hurlburt was set up to measure the extent of introspective accuracy by gathering introspective reports from a single individual who was given the pseudonym 'Melanie'. Melanie was given a beeper which sounded at random moments, and when it did she had to note what she was currently feeling and thinking. After analyzing the reports the authors had mixed views about the results, the correct interpretation of Melanie's claims and her introspective accuracy. Even after long discussion the two authors disagreed with each other in the closing remarks, Schwitzgebel being pessimistic and Hurlburt optimistic about the reliability of introspection.

Choice blindness

Inspired by the Nisbett and Wilson paper, Petter Johansson and colleagues investigated subjects' insight into their own preferences using a new technique. Subjects saw two photographs of people and were asked which they found more attractive. They were given a closer look at their "chosen" photograph and asked to verbally explain their choice. However, using sleight of hand

, the experimenter had slipped them the other photograph rather than the one they had chosen. A majority of subjects failed to notice that the picture they were looking at did not match the one they had chosen just seconds before. Many subjects confabulated explanations of their preference. For example, a man might say "I preferred this one because I prefer blondes" when he had in fact pointed to the dark-haired woman, but had been handed a blonde. These must have been confabulated

 because they explain a choice that was never made.

The large proportion of subjects who were taken in by the deception contrasts with the 84% who, in post-test interviews, said that hypothetically they would have detected a switch if it had been made in front of them. The researchers coined the term "choice blindness" for this failure to detect a mismatch.

A follow-up experiment involved shoppers in a supermarket tasting two different kinds of jam, then verbally explaining their choice while taking further spoonfuls from the "chosen" pot. The pots were rigged so that when explaining their choice, the subjects were tasting the jam they had previously rejected. A similar experiment was also done with tea. Another variation involved subjects choosing between two objects displayed on powerpoint slides, then explaining their choice when the description of what they chose has been altered.

Explaining biases

Pronin argues that over-reliance on introspected feelings and intentions is a factor in a number of different biases. For example, by focusing on their current good intentions, people can overestimate their likelihood of behaving virtuously.

 is an established phenomenon that people rate themselves as less susceptible to bias than their peer group. Emily Pronin and Matthew Kugler argue that this phenomenon is due to the introspection illusion. In their experiments, subjects had to make judgments about themselves and about other subjects. They displayed standard biases, for example rating themselves above the others on desirable qualities (demonstrating illusory superiority

). The experimenters explained cognitive bias, and asked the subjects how it might have affected their judgment. The subjects rated themselves as less susceptible to bias than others in the experiment (confirming the bias blind spot

). When they had to explain their judgments, they used different strategies for assessing their own and others' bias.

Pronin and Kugler's interpretation is that when people decide whether someone else is biased, they use overt behavior. On the other hand, when assessing whether or not they themselves are biased, people look inward, searching their own thoughts and feelings for biased motives. Since biases operate unconsciously, these introspections are not informative, but people wrongly treat them as reliable indication that they themselves, unlike other people, are immune to bias.

Pronin and Kugler tried to give their subjects access to others' introspections. To do this, they made audio recordings of subjects who had been told to say whatever came into their heads as they decided whether their answer to a previous question might have been affected by bias. Although subjects persuaded themselves they were unlikely to be biased, their introspective reports did not sway the assessments of observers.

When asked what it would mean to be biased, subjects were more likely to define bias in terms of introspected thoughts and motives when it applied to themselves, but in terms of overt behavior when it applied to other people. When subjects were explicitly told to avoid relying on introspection, their assessments of their own bias became more realistic.

In perceptions of conformity

Another series of studies by Pronin and colleagues examined perceptions of conformity
Conformity
Conformity is the process by which an individual's attitudes, beliefs, and behaviors are influenced by other people.Conformity may also refer to:*Conformity: A Tale, a novel by Charlotte Elizabeth Tonna...

. Subjects reported being more immune to social conformity than their peers. In effect, they saw themselves as being "alone in a crowd of sheep". The introspection illusion appeared to contribute to this effect. When deciding whether others respond to social influence, subjects mainly looked at their behavior, for example explaining other student's political opinions in terms of following the group. When assessing their own conformity, subjects treat their own introspections as reliable. In their own minds, they found no motive to conform, and so decided that they had not been influenced.

 player taking a series of free throws. When they were instructed to visualise him making his shots, they felt that they had contributed to his success.

If the introspection illusion contributes to the subjective feeling of free will, then it follows that people will more readily attribute free will to themselves rather than others. This prediction has been confirmed by three of Pronin and Kugler's experiments. When college students were asked about personal decisions in their own and their roommate's lives, they regarded their own choices as less predictable. Staff at a restaurant described their co-workers' lives as more determined (having fewer future possibilities) than their own lives. When weighing up the influence of different factors on behavior, students gave desires and intentions the strongest weight for their own behavior, but rated personality traits as most predictive of other people.

It should be noted that criticism to Wegner's claims regarding the significance of introspection illusion for the notion of free will has been published (e.g. criticism by H. Andersen in his paper with the title 'Two Causal Mistakes in Wegner's Illusion of Conscious Will' ; Also as a criticism, read "On the alleged illusion of conscious will' by Van Duijn and Sacha Bem. Other papers can be found).
