The halo effect is a cognitive bias that can lead individuals to form opinions about one aspect of something based on their perception of other aspects of it. As an illustration, the halo effect can lead individuals to make assumptions about someone’s personality solely based on their physical attractiveness.
The term “halo effect” refers to the phenomenon whereby our perception of one distinguishing characteristic affects how we evaluate a particular entity, whether it be a person, thing, or company. This perception can greatly impact how we view the entity’s other traits and our overall perception of it.
Understanding the halo effect is crucial because it has a widespread presence and can impact how we perceive others and how they perceive us. In the following article, you will discover valuable insights into the halo effect, including real-life examples of its impact on individuals. Additionally, you will gain a deeper understanding of how to effectively address and mitigate its influence.
Examples of the halo effect
A renowned study by psychologist Solomon Asch conducted in 1946 contains an iconic illustration of the halo effect. One of the most well-known experiments from the study revolved around presenting participants with two different descriptions of a person:
A: intelligent—industrious—impulsive—critical—stubborn—envious
B: envious—stubborn—critical—impulsive—industrious—intelligent
Both descriptions have the same traits, but there is a difference in the way they are presented. Description A starts with positive traits, then includes some ambiguous traits, and ends with a negative trait. On the other hand, description B lists these traits in reverse order. However, this subtle distinction created a positive impression among participants, resulting in a notable variation in their perception of the individual being discussed:
“The impression produced by A is predominantly that of an able person who possesses certain shortcomings which do not, however, overshadow his merits. On the other hand, B impresses the majority as a ‘problem,’ whose abilities are hampered by his serious difficulties. Further, some of the qualities (e.g., impulsiveness, criticalness) are interpreted in a positive way under Condition A, while they take on, under Condition B, a negative color.”
Daniel Kahneman, a renowned psychologist, economist, and Nobel laureate, shared the following story as another intriguing illustration of the halo effect:
“Early in my career as a professor, I graded students’ essay exams in the conventional way. I would pick up one test booklet at a time and read all that student’s essays in immediate succession, grading them as I went. I would then compute the total and go on to the next student.
I eventually noticed that my evaluations of the essays in each booklet were strikingly homogeneous. I began to suspect that my grading exhibited a halo effect, and that the first question I scored had a disproportionate effect on the overall grade. The mechanism was simple: if I had given a high score to the first essay, I gave the student the benefit of the doubt whenever I encountered a vague or ambiguous statement later on. This seemed reasonable. Surely a student who had done so well on the first essay would not make a foolish mistake in the second one!
But there was a serious problem with my way of doing things. If a student had written two essays, one strong and one weak, I would end up with different final grades depending on which essay I read first. I had told the students that the two essays had equal weight, but that was not true: the first one had a much greater impact on the final grade than the second.”
From the book “Thinking Fast and Slow.“
A study that revealed how a woman’s weight can affect her personality is another example of the halo effect. In the study, participants were presented with a photograph of a woman, along with details about her interests and overall lifestyle. A group of participants were given an unaltered picture of the woman, while another group received a picture where the woman appeared to be around 50 pounds heavier due to padding.
When asked for their opinions on the woman they read about, participants who saw the picture of the thinner woman rated her as more attractive, with a better personality, and more likely to achieve success in her career. This is in spite of the fact that these participants were given identical background information about the woman as the participants who viewed the image of the heavier woman. This suggests that they might have been subject to a halo effect, where their perception of the woman’s body affected their perception of her personality and abilities.
Ultimately, numerous other instances demonstrate the impact of the halo effect on individuals’ thought processes. As an example:
- When considering potential partners for political discussion, individuals tend to perceive more visually appealing candidates as being more informed and convincing and as more reliable sources of political information.
- People occasionally gave essays written by attractive people higher ratings than essays written by unattractive people when evaluating them.
- When assessing their teachers, students who held a strong opinion about a specific trait of their teacher tended to let that opinion influence their overall evaluation of the teacher’s performance.
It is important to note that there is a common belief that individuals who are physically attractive are more likely to possess socially desirable traits. This belief is often referred to as the physical attractiveness stereotype or the “what is beautiful is good” stereotype.
Understanding the reasons behind the halo effect
“The sequence in which we observe characteristics of a person is often determined by chance. Sequence matters, however, because the halo effect increases the weight of first impressions, sometimes to the point that subsequent information is mostly wasted.”
From “Thinking, Fast and Slow“, by Daniel Kahneman
There are various factors that contribute to individuals experiencing the halo effect.
Initially, individuals may encounter the halo effect as they strive to validate their initial impressions of someone or something. Demonstrating their correctness serves two primary objectives:
- It provides the individual who created that impression with a sense of satisfaction.
- It can be beneficial for individuals to avoid the unpleasant experience of cognitive dissonance, especially when they realize that their initial impression was incorrect and they must now reconcile it with a more accurate one.
Take, for instance, when we come across someone who possesses a single positive trait, like a great sense of humor. In such cases, we tend to quickly develop a favorable opinion of that person, as that’s the only information we have at hand. Later, as we gather more information about them, we strive to validate our initial impression, even if subsequent discoveries may challenge it. We are hesitant to uncover any evidence that may prove our initial impression to be incorrect.
It’s worth noting that in this scenario, the halo effect can be seen as connected to the confirmation bias. The confirmation bias is a cognitive bias that leads us to seek out and interpret information in a manner that aligns with our existing beliefs.
Additionally, there are instances where individuals may encounter the halo effect due to the challenge of distinguishing between various characteristics that make up an entity. Basically, when people attempt to evaluate specific attributes in someone or something, they find it difficult to evaluate each of these attributes separately, and their evaluation of one attribute influences their evaluation of other attributes.
When evaluating someone’s competence in the workplace, it can be challenging to solely focus on their abilities without considering other factors that may not be relevant, such as their likability or confidence.
Furthermore, individuals may occasionally encounter the halo effect, as their cognitive load is reduced when they concentrate on a specific characteristic while evaluating others. Typically, when individuals are trying to form opinions about others, the greater the number and complexity of factors they consider, the more challenging it becomes for them to develop an accurate impression.
By focusing on a prominent aspect, whether it’s visually striking or easily understandable, individuals can simplify the process of forming impressions of others. Unfortunately, this can lead to a decrease in the accuracy of those impressions. However, in many cases, people are either willing to overlook this potential decrease in accuracy or they are not considering it when making this type of assessment.
Additionally, there are instances where people’s trust in correlations as a result of previous interactions influences the halo effect. Given the frequent observation of correlations between certain traits, it is common for people to make assumptions about the presence of other traits based on the presence of one. In some instances, considering these correlations can help form impressions that are more likely to be accurate.
As we gain more experience, we may find that products with appealing visual designs are often trustworthy in terms of their technical performance. This can lead us to assume that a particular product is reliable solely based on its good visual design.
Therefore, the halo effect can be a valuable heuristic in certain circumstances. This is because, when we process information, we often rely on mental shortcuts that can be helpful when we need to make quick decisions or when we lack certain key pieces of information.
For instance, when faced with the task of selecting between two products without knowing which one performs better, we often rely on visual design to make our decision. We assume that a visually appealing product is likely to have better performance.
Naturally, relying on the halo effect as a decision-making tool is not infallible and may occasionally steer us in the wrong direction. This is particularly common in situations where the individual responsible for the matter at hand is familiar with the halo effect and deliberately exploits it to influence our perception.
Understanding the impact of the halo effect
The halo effect and how you perceive others
When considering the impact of the halo effect, it’s crucial to remember that it affects your perception of others. It is important to keep in mind the impact of the halo effect on our thoughts, whether it is positive or negative. This awareness can help us evaluate things more objectively and make more logical decisions.
It’s crucial to remember that you shouldn’t automatically develop a positive impression of someone just because they possess a single positive trait, such as physical attractiveness. Similarly, having one negative trait doesn’t warrant forming an immediate negative impression of someone.
To minimize the impact of the halo effect when evaluating others, it can be helpful to employ cognitive debiasing techniques, such as taking your time to think through your reasoning. The most efficient strategies will be those that aim to tackle the root causes of your halo effect specifically.
For instance, if you find yourself falling into the trap of the halo effect by always seeking confirmation of your initial judgments about people, you can minimize the chances of this happening by forming two potential impressions of individuals when you first encounter them. Hold onto both of these impressions until you gather more information that will help you make a more informed decision.
The impact of others’ perception on your reputation
Considering the halo effect, it’s crucial to remember its impact on how others perceive you and your creations. It’s important to recognize that your actions and characteristics in one aspect of your life can significantly impact how others perceive you in different areas, ultimately shaping their overall perception of you.
As an illustration, a study conducted an experiment where students were shown an interview with a college professor who had a non-native English accent. There were two groups of students, each of whom viewed a slightly varied version of the interview.
In one version, the instructor exuded a welcoming and amiable demeanor, while in the other version, he appeared aloof and detached. Students who watched the interview with the friendly instructor found his appearance, mannerisms, and accent to be appealing, while students who watched the distant instructor rated the same attributes as irritating.
This is an example of how, by leveraging the power of perception, you can make subtle adjustments in your behavior that have a significant impact on how others view you.
Differences in the halo effect
While the halo effect can have an impact on people’s perceptions in different scenarios, it is crucial to remember that it is not always a factor in people’s thought processes. Additionally, the exact way in which it affects people’s thinking may not be easily discernible.
For instance, when people rate essays based on how attractive they think the author is, the halo effect was only evident when a male participant thought they were rating an essay by a female author. The participants’ ratings of a female author’s essay were unaffected by her appearance. Regardless of the participants’ gender, the same was true for a man’s essay.
This, and similar types of variation, also emerged in numerous other studies on the halo effect. It is important to consider the halo effect, but it should not be automatically assumed to be a constant factor in people’s judgment and decision-making processes.

The impact of perception in marketing
Typically, the halo effect is discussed in relation to its impact on our perception of others. Within this context, the halo effect has the potential to shape our overall impression of an individual based on our perception of a specific trait, often the first one we come across or one that stands out in some manner.
Nevertheless, the halo effect extends beyond our perception of individuals. It can also impact the way we evaluate other things, like products and companies. For instance, if you hold a favorable opinion of a particular brand, you’re more inclined to purchase their products, even if your positive impression isn’t directly tied to the specific product in question.
The halo effect is an important factor to consider in marketing and is frequently discussed in relation to evaluating the worth of brand names.
The negative bias
The horns effect is a cognitive bias that can lead us to form negative impressions of someone or something in one area, which then affects our overall impression of them in other areas. As an illustration, a study on classroom behavior revealed that when young children exhibited defiant behavior, teachers tended to misidentify them as being hyperactive or having attention-deficit hyperactivity disorder (ADHD).
Similarly, when it comes to consumer products, the horns effect can come into play. For instance, if you have a negative impression of a product based on its appearance, you might assume that it will perform poorly, even if that may not be true.
It’s important to note that, when it comes to terminology, the halo effect covers both positive and negative impressions.
However, in certain situations, the halo effect is associated with positive impressions, while the horns effect is associated with negative impressions. This is why the horns effect is sometimes referred to as a reverse halo effect, even though it actually pertains to the same cognitive bias as the halo effect.
The origin of the halo effect
The concept of the halo effect was introduced by Edward Thorndike, a prominent American psychologist, in his 1920 paper titled ‘A Constant Error in Psychological Ratings’. In the paper, Thorndike makes the following statement:
“In a study made in 1915 of employees of two large industrial corporations, It appeared that the estimates of the same man in a number of different traits such as intelligence, industry, technical skill, reliability, etc., etc., were very highly correlated and very evenly correlated. It consequently appeared probable that those giving the ratings were unable to analyze out these different aspects of the person’s nature and achievement and rate each in independence of the others. Their ratings were apparently affected by a marked tendency to think of the person in general as rather good or rather inferior and to color the judgments of the qualities by this general feeling.”
Thorndike then adds to the evidence that supports the first study by showing that when army officers were rated by their superiors on their physical traits, intelligence, leadership skills, and personal character, the ratings showed a strong and consistent correlation, even though the officers were told to rate each trait separately. For instance, it was found that the intelligence ratings of officers were just as strongly linked to their physical qualities as they were to their leadership ability and personal character. This is noteworthy considering the expected weaker association between intelligence and physical qualities.
Thorndike then points out that a similar issue arose with aviation officers. Their overall ability to perform officer duties was strongly linked to their specialized technical skills in flying, to a greater extent than one would typically anticipate. He observes that this implies that a general sense of excellence is attributed to impacting the rating of the special ability, or vice versa.
Thorndike also discusses additional research by Knight and Boyce that demonstrates a comparable phenomenon in the evaluation of educators. During the discussion, he highlights that the characteristic of ‘voice’ showed a strong correlation with the traits of ‘intelligence’ and ‘interest in community affairs’, surpassing the usual expectations.
In conclusion, Thorndike states in his paper that:
“The writer has become convinced that even a very capable foreman, employer, teacher, or department head is unable to treat an individual as a compound of separate qualities and to assign a magnitude to each of these in independence of the others. The magnitude of the constant error of the halo, as we have called it, also seems surprisingly large…”
It is worth noting that Thorndike does not explicitly mention the concept of the ‘halo effect’ in the paper. However, he does refer to this phenomenon multiple times using the term ‘halo’, including in the quote above, where he discusses the ‘constant error of the halo’.
According to the Oxford English Dictionary, S. first introduced the idea of the “halo effect” in a 1938 paper. M. conducted a study in which
“We noted the importance of a general impression gained of the candidate, which was sometimes such as to result in resistance to bias, and sometimes the mechanism through which the bias appeared to operate. Such general impressions, often called ‘ halo ‘ effects, have already been noted to affect the diagnosis of personal qualities…”
Summary and conclusions
- The halo effect is a cognitive bias that can lead individuals to form opinions about one aspect of something based on their perception of other aspects of it.
- For instance, when individuals perceive someone as physically appealing, the halo effect can lead them to believe that this person possesses a more captivating personality than they would assume if the person were unattractive.
- There are several reasons why we experience the halo effect. One of them is our tendency to confirm our initial impressions of things. Additionally, it can be challenging for us to separate and evaluate different traits of the same entity, leading to the halo effect. Making judgments based on this effect is also easier for us, as we rely on certain correlations between different traits. In some cases, these assumptions based on the halo effect can be helpful heuristics.
- It’s important to keep in mind the impact of the halo effect on our perception of others. Being aware of this bias can help us make more objective decisions and avoid making unfounded assumptions about people in situations where it would be inappropriate.
- It’s important to consider how the halo effect can impact how others perceive you. Your actions in one area can greatly influence how people see you overall, whether positively or negatively.
