What is Primacy Bias – Causes & Examples
Published by at July 11th, 2023 , Revised On October 5, 2023
Do you know that first impressions profoundly influence how we perceive the world? How we view and interact with people, circumstances, and even objects may all be shaped by our early impressions.
This first impression is called the primacy bias, which can also colour our expectations, biases, and judgements. This eventually affects our perspective as a whole. Let’s understand the primacy bias definition in detail.
What is Primacy Bias?
‘’Primacy Bias is the tendency to remember and give greater importance or weight to information presented first in a series or sequence.’’
When encountering a series of information or stimuli, the initial information has a stronger impact and is more likely to be encoded and retained in memory.
Primacy effect bias can influence our perceptions, judgments, and decisions more significantly than the information presented later.
Primacy bias meaning can affect various aspects of life, including impression formation, decision-making, and information processing, as the initial information serves as a mental anchor against which subsequent information is compared.
What are the Causes of Primacy Bias?
-
Encoding and Attention
When information is presented, our attention is usually at its peak at the start. Therefore, we are more likely to encode and store the initial knowledge in our memory effectively. The impact and retention of the initial piece of information received are increased due to this attentional bias.
-
Cognitive Availability
Our memory is more readily available to the information offered first. It is, therefore, simpler to access retrieval and decision-making procedures. Early information is more influential in forming our judgements and decisions because it is so simple to acquire.
-
Anchor Point
The information initially supplied frequently acts as an anchor or point of comparison for future information that is evaluated. The initial piece of knowledge serves as a conceptual frame of reference for later assessments and choices.
It can be difficult to stray from the initial perception even when confronted with contrary facts because of this anchoring effect.
-
Memory Consolidation
Our memory tends to consolidate and cement earlier information more quickly than later information. The memory trace linked to the initial information is strengthened during consolidation, making it more change-resistant. As a result, later information might be overlooked or forgotten, supporting the primacy bias.
-
Impact on the Mind and Heart
The initial information received might have a significant psychological and emotional effect. Initial reactions frequently cause more intense emotional reactions and influence subsequent views. It can be challenging to counteract the impact of the initial information because these emotional reactions can skew how we interpret future information.
What are the Basic Differences Between Primacy Bias and Recency Bias?
Primacy and recency biases are cognitive biases that affect how we perceive and remember information. Primacy and recency biases have the following differences:
| Primacy Bias | Recency Bias |
| Primacy bias refers to the tendency to remember and give more importance to information presented first in a series. | Recency bias refers to the tendency to remember and give more importance to information that is presented last in a series. |
| It occurs when the initial information has a greater impact on overall perception and decision-making. | It occurs when the most recent information has a greater impact on overall perception and decision-making. |
| Primacy bias can influence judgments and evaluations because people rely heavily on the first information they encounter. | Recency bias can affect judgments and evaluations because people tend to give more weight to the most recent information they receive. |
| It can be attributed to factors such as the encoding and consolidation processes of memory and the novelty and attention given to the initial information. | It can be attributed to short-term memory’s limited capacity and the salience of the most recent information. |
| Primacy bias is more likely to occur when there is a time gap between the initial and subsequent information. | Recency bias is more likely to occur when the information is presented immediately before the evaluation or decision-making process. |
| It can lead to a “first impression” effect, where the initial information strongly influences subsequent perceptions and judgments. | It can result in a “last impression” effect, where the most recent information strongly influences subsequent perceptions and judgments. |
| Primacy bias can be mitigated by increasing the exposure to subsequent information or providing additional context and perspectives. | Recency bias can be mitigated by allowing sufficient time for reflection and considering the information presented earlier in the series. |

How to Avoid Primacy Bias?
People can strive for more balanced and informed evaluations, consider all pertinent facts, and make more objective decisions by being conscious of this bias and actively attempting to reduce its impact.
Reducing primacy bias encourages justice, accuracy, and better overall results in many areas, such as education, hiring, consumer choices, and interpersonal relationships.
-
Awareness
Recognise a tendency to spend excessive weight on early information. Individuals can consciously strive to evaluate all pertinent facts before making judgements or decisions by becoming aware of their prejudice.
-
Refrain from Making Snap Judgements
Give yourself time to collect and analyse more data to build a more complete and accurate perspective.
-
Listen Actively
Actively listen during presentations or debates and take notes to ensure that the following content is given the same level of care. Making thorough notes can help fight the inclination to concentrate only on the initial information.
-
Look for Different Viewpoints
Be on the lookout for different perspectives. Engaging with many viewpoints can refute first impressions and provide the subject matter with a complete grasp.
-
Implement Organised Decision-Making Procedures
Implementing organised decision-making procedures that entail methodically assessing various information sources is important. Through the provision of a framework for taking into account all pertinent elements, this method aids in reducing the impact of primacy bias.
-
Feedback and Ongoing Learning
Adopt a growth attitude and actively seek feedback. Challenge your preconceptions and get feedback from others to assist your decision-making process to be less influenced by initial information.
Primacy Bias Examples from our Everyday Life
The following are some examples of primacy bias in our daily life:
Primacy Bias Example in the Workplace
Let’s understand primacy bias in the workplace with this example.
In a job interview, primacy bias can influence the hiring decision. When the first candidate is interviewed, their initial impression tends to stick in the interviewer’s mind.
Subsequent candidates may be compared to the first, making it difficult to assess their qualifications objectively. Even if later candidates possess stronger skills or experience, the primacy bias may cause the interviewer to favour the initial candidate.
This bias can lead to the selection of a less qualified candidate based solely on the strong impression created by the first interviewee, potentially impacting the overall effectiveness and success of the hiring process.
Primacy Bias Example in Education
Suppose you are presenting a topic in the classroom. The primacy bias can affect how we remember and evaluate the information in a series of presentations or speeches. The first presenter may make a strong impact, making it difficult for subsequent presenters to leave a lasting impression, even if their content is of higher quality.
In educational settings, the primacy bias can affect the retention and understanding of information. The first concepts introduced in a learning sequence may be better remembered and understood compared to later concepts, potentially leading to an incomplete or skewed understanding of the subject matter.
Primacy Bias in Media
The way news stories are presented can shape our perception and understanding of current events. The initial news story we encounter may influence our perspective and interpretation of subsequent news stories, potentially leading to a biased understanding of the events.
Primacy Bias in Impression Formation
The primacy bias can heavily impact our initial impression when meeting new people. The first impression created by someone can significantly influence how we perceive and interpret their subsequent behaviours and actions, even if they deviate from our initial impression.
Frequently Asked Questions
Primacy bias refers to the tendency to remember and give greater importance to information that is presented first in a series, leading to a stronger influence on overall perception and decision-making.
Primacy bias in media refers to the tendency of audiences to remember and be influenced more by the initial information or messages presented in a media report, which can shape their overall perception and understanding of a particular topic or issue.
The causes of primacy bias include the heightened attention and encoding given to initial information, the cognitive availability of the first information in memory, confirmation bias in favour of initial impressions, the anchoring effect of the initial information as a reference point, and the consolidation of initial information in memory.
Primacy bias affects impression formation by influencing the initial information we encounter, which has a stronger impact on our overall perception and judgment of a person, event, or topic. The first information shapes our initial impressions and can be difficult to overcome or change.
