Information Processing Bias
We don’t see the world as it is; we see it as we are.
How do you make decisions—based on facts or feelings? The way your brain processes information can create biases that impact your choices without you even realizing it. Information processing bias is a fascinating psychological phenomenon that shapes how we see the world.
Have you ever noticed how two people can look at the same situation and come to completely different conclusions? It’s not because one of you is wrong; it’s because your brains are filtering information through your experiences, emotions, and preconceptions. In this blog post, we’ll explore the surprising ways information processing bias works and how to recognize it in your own thinking. Get ready to have your mind blown!
Attentional Bias
Attentional bias occurs when people focus all their attention on a single stimulus or sensory input. This bias influences not only what we see in the environment but also the decisions we make based on what we see.
In many situations, especially when dealing with threats, attentional bias can be beneficial. It allows you to focus on the aspects of your surroundings that pose the greatest threat and require action. However, paying too much attention to things that are not actual threats can lead to issues like irrational decision-making and stress.
Automation Bias
Automation bias is a common error made by people in highly automated decision-making scenarios. Humans often try to reduce mental strain by relying on automated assistance. However, according to Mosier and colleagues, the use of automated aids may lessen the likelihood that decision-makers will engage in cognitive efforts to look for additional information or interpret available data in a complex manner.
For example, Layton, Smith, and McCoy observed pilots using a graphical tool for flight planning. They found that automation bias caused pilots to follow the computer’s advice, even when it wasn’t optimal, leading to potentially unfavorable outcomes.
Choice-Supportive Bias
Choice-supportive bias is the tendency to attribute favorable characteristics to a decision or alternative after it has been made. People often remember positive features of the choices they made and negative attributes of the options they rejected.
Henkel & Mather, for instance, asked participants to choose between two cars with different attributes. After seven days, participants identified more positive attributes for the car they chose and more negative characteristics for the car they rejected.
Context Effect
Context effect refers to the difficulty of recalling memories that are out of context. McKenzie and Tiberghien conducted an experiment where participants looked at a list of words and did recognition tests with target words presented in the same or different contexts. They found that context significantly affects memory recall, partly due to familiarity and recognition.
Contrast Effect
Contrast effect is a bias where a decision-maker views information differently based on comparisons. For instance, in speed dating, Bhargava and Fisman studied around 500 people making over 7,000 decisions. They found a contrast effect in judgments, particularly among male evaluators, when individuals were compared to others.
Cross-Race Effect
The cross-race effect is the tendency for people to more easily recognize faces of their own race or ethnicity compared to those of other races or ethnicities.
Fading Effect Bias
Fading effect bias is the tendency for emotions associated with positive memories to decline more slowly over time than those linked with negative memories. Gibbons and colleagues studied the influence of drinking frequency on both alcohol-related and non-alcohol-related events. They found that people who drank more had a stronger fading effect bias for alcohol-related events.
Duration Neglect
Duration neglect is when people place a high value on short-term experiences and less emphasis on the duration of an event.
Egocentric Bias
Egocentric bias occurs when someone views the world from a personal perspective, often overestimating their self-importance.
False Memory
False memory is the misrepresentation of an actual event or the creation of a completely new one. Loftus showed that false memories can be created by blending real experiences with suggestions from others.
Focusing Effect
The focusing effect is the tendency to make decisions based on the most noticeable evidence, ignoring other information. For example, if your current car has a small trunk, you might choose a new car with a larger trunk, focusing solely on that feature.
Generation Effect
The generation effect refers to the increased likelihood of remembering information we actively generate rather than passively receive. Slamecka and Graf found that participants had better memory recall for words they generated compared to those they merely read.
Google Effect
The Google effect is the tendency to forget information that is expected to be accessible via an Internet search in the future.
Hindsight Bias
Hindsight bias occurs when people overestimate their ability to predict unpredictable outcomes. For example, after it starts raining, you might think, “I knew it was going to rain,” even though the prediction was uncertain.
Hostile Media Effect
The hostile media effect arises when competing parties view the same media coverage of a controversial subject as biased against their side.
Humor Effect
The humor effect is the tendency to remember humorous material more frequently than non-humorous content.
Illusion of Truth Effect
The illusion of truth effect is the tendency to believe a statement is true if it has been repeated frequently, regardless of its accuracy.
Illusory Correlation
Illusory correlation is the perception of a relationship between two variables when only a minor or no actual relationship exists.
Information Bias
Information bias occurs when people seek excessive information to make decisions, mistakenly assuming that all information is valuable.
Level of Processing Effect
The level of processing effect suggests that memories processed deeply are more durable than those processed superficially. This is achieved through cognitive processing.
List Length Effect
The list length effect indicates that shorter lists are better for recognition than longer ones. However, Dennis and Humphreys found that this effect can be mitigated by factors like concentration and retention interval.
Misinformation Effect
The misinformation effect refers to how post-event information can interfere with the original memory of the event. Loftus’s study showed that misleading questions can alter participants’ recollection of an event.
Mood-Congruent Memory Bias
Mood-congruent memory bias is the tendency to recall experiences that match one’s current mood. Watkins and colleagues found that depressed individuals had higher priming for negative words.
Peak-End Rule
The peak-end rule is the tendency to evaluate experiences based on their most intense point and their end. Kahneman and colleagues found that participants preferred longer periods of pain that ended on a less painful note compared to shorter periods of more intense pain.
Persistence
Persistence is the inability to forget a memory one would prefer to forget. Ochsner found that people are more likely to recall negative emotional images vividly.
Processing Difficulty Effect
The processing difficulty effect is the tendency to remember information that was challenging to process better than simpler information. O’Brien and Myers found that participants remembered difficult text passages better than straightforward ones.
Serial Position Effect
The serial position effect indicates that the first and last items in a series are more likely to be remembered than those in the middle. This phenomenon is well-known in media and advertising.
Suggestibility
Suggestibility is the tendency to incorporate external information into personal memories. Schacter et al. found that suggestive questions can cause memory distortions.
Zeigarnik Effect
The Zeigarnik effect is the tendency to remember unfinished tasks better than completed ones. Participants in a study remembered interrupted tasks more than those they completed.
Conclusion
Understanding information processing biases can help us make more informed decisions by recognizing our cognitive tendencies. Whether it’s attentional bias, the illusion of truth effect, or the Zeigarnik effect, these biases shape our perceptions and actions in subtle yet significant ways. By being aware of these biases, we can strive to think more critically and make choices based on a balanced view of the information available to us.
