Cultural differences[ edit ] A vast majority of the literature on illusory superiority originates from studies on participants in the United States. However, research that only investigates the effects in one specific population is severely limited as this may not be a true representation of human psychology.
More recent research investigating self-esteem How to find the average other countries suggests that illusory superiority depends on culture. The theory that those with high self-esteem maintain this high level by rating themselves highly is not without merit—studies involving non- depressed college students found that they thought they had more control over positive outcomes compared to their peers, even when controlling for performance.
Students were able to recall a great deal more negative personality traits about others than about themselves. Relation to mental health[ edit ] Main article: Depressive realism Psychology has traditionally assumed that generally accurate self-perceptions are essential to good mental health.
This was challenged by a paper by Taylor and Brown, who argued that mentally healthy individuals typically manifest three cognitive illusions—illusory superiority, illusion of controland optimism bias.
One study claimed that "mentally normal" groups were contaminated by "defensive deniers", who are the most subject to positive illusions. This is suggested to link to the role of these areas in processing "cognitive control".
This implies that our estimates of the scores of others are even more conservative more influenced by the previous expectation than our estimates of our own performance more influenced by the new evidence received after giving the test.

The difference in the conservative bias of both estimates conservative estimate of our own performance, and even more conservative estimate of the performance of others is enough to create illusory superiority. This theory was first tested by Weinstein ; however, this was in an experiment relating to optimistic biasrather than the better-than-average effect.
The study involved participants rating certain behaviors as likely to increase or decrease the chance of a series of life events happening to them.
To test this theory, Perloff and Fetzer asked participants to compare themselves to specific comparison targets like a close friend, and found that illusory superiority decreased when they were told to envision a specific person rather than vague constructs like "the average peer".
However these results are not completely reliable and could be affected by the fact that individuals like their close friends more than an "average peer" and may as a result rate their friend as being higher than average, therefore the friend would not be an objective comparison target.
Egocentrism Another explanation for how the better-than-average effect works is egocentrism. This is the idea that an individual places greater importance and significance on their own abilities, characteristics, and behaviors than those of others. Egocentrism is therefore a less overtly self-serving bias.
Kruger found support for the egocentrism explanation in his research involving participant ratings of their ability on easy and difficult tasks. It was found that individuals were consistent in their ratings of themselves as above the median in the tasks classified as "easy" and below the median in the tasks classified as "difficult", regardless of their actual ability.
In this experiment the better-than-average effect was observed when it was suggested to participants that they would be successful, but also a worse-than-average effect was found when it was suggested that participants would be unsuccessful.
Focalism Yet another explanation for the better-than-average effect is "focalism", the idea that greater significance is placed on the object that is the focus of attention.
Most studies of the better-than-average effect place greater focus on the self when asking participants to make comparisons the question will often be phrased with the self being presented before the comparison target—"compare yourself to the average person". According to focalism this means that the individual will place greater significance on their own ability or characteristic than that of the comparison target.
This also means that in theory if, in an experiment on the better-than-average effect, the questions were phrased so that the self and other were switched e. However, two studies found a decreased effect of optimistic bias when participants were asked to compare an average peer to themselves, rather than themselves to an average peer.
Furthermore, the majority of the group is likely to rate themselves as above average. Better-than-average heuristic[ edit ] Alicke and Govorun proposed the idea that, rather than individuals consciously reviewing and thinking about their own abilities, behaviors and characteristics and comparing them to those of others, it is likely that people instead have what they describe as an "automatic tendency to assimilate positively-evaluated social objects toward ideal trait conceptions".
Importantly, Alicke noted that this ideal position is not always the top of the scale; for example, with honesty, someone who is always brutally honest may be regarded as rude—the ideal is a balance, perceived differently by different individuals.Biomedical engineers combine engineering principles with medical sciences to design and create equipment, devices, computer systems, and software used in healthcare.
