![]() People realize that being biased is not a desirable quality, so they tend to view their own decisions as being the result of pure logic and reason. Self-perception: A desire to see oneself positively as a rational, logical thinker plays a role. There are a number of different factors that contribute to this type of bias. “This susceptibility to the bias blind spot appears to be pervasive, and is unrelated to people’s intelligence, self-esteem, and actual ability to make unbiased judgments and decisions.” What Causes the Bias Blind Spot? Whether a good decision-maker or a bad one, everyone thinks that they are less biased than their peers,” explained Carey Morewedge, one of the study’s authors and an associate professor of marketing at Boston University. “People seem to have no idea how biased they are. The majority of those in the study, approximately 85%, actually believed that they were less biased, whether or not they exhibited unbiased decision-making. Out of 661 participants, only one person stated that they were more biased than the average person. According to a study published in the journal Management Science, nearly all people experience the blind spot bias. Interestingly, people often believe that they are less likely to be biased than their peers. Sometimes the consequences of this flawed thinking may be relatively minor, but in other situations, it can lead to regrettable outcomes. This blind spot for your own biases can lead to faulty or distorted thinking, which can lead to poor decision-making. As you weigh a decision, many factors play a role in your thoughts, yet it is often the factors we are unaware of that may impact these choices in ways we may not have considered. The bias blind spot is similar in that it is something that affects the choices you make, even though you cannot see it. Unable to see the other car, you made a driving maneuver that easily could have ended in a traffic accident. As you are making the move, another car suddenly blares its horn and you instantly realize that there indeed was another vehicle in that lane–it was in your blind spot.Ī blind spot is simply something that you consistently overlook, often unintentionally. Seeing nothing in the other lane, you begin to merge over. Effects of the Bias Blind Spot What Is a Blind Spot?Īs you are driving down the freeway, you glance over your shoulder and check the rear-view mirror.These results are consistent with the idea that perceptual filling-in of the blind spot depends on local processes generated at the physiological edge of the cortical representation. Filling-in was incomplete, when the frame was no longer contiguous with the blind spot border due to an eye movement. Uniform filling-in was observed with frame widths as narrow as 0.05° visual angle for color and 0.2° for texture. To better understand these processes, we determined the minimum region around the blind spot that needs to be stimulated for filling-in by carefully mapping the blind spot and presenting individually fitted stimulus frames of different width around it. The mechanisms underlying this kind of perceptual filling-in remain controversial. Rather we perceive the brightness, color, and texture of the adjacent area as if they were actually there. ![]() ![]() Looking at the world with one eye, we do not notice a scotoma in the receptor-free area of the visual field where the optic nerve leaves the eye.
