a description of a time when you were certain your first impression of someone you had just met was accurate, only to discover subsequently that you were mistaken. Describe how social psychology theory explains this phenomenon.


First impressions play a crucial role in social interactions and can often shape our initial perceptions of others. These impressions are formed quickly and are based on limited information, such as physical appearance, behavior, and verbal cues. While we like to believe our first impressions are accurate and reliable, it is not uncommon to discover later on that we were mistaken. This essay will explore a personal experience where I was certain about my first impression of someone but later realized my perception was incorrect. Furthermore, we will draw upon social psychology theories to explain this phenomenon.

Personal Experience:

The incident I will discuss centers around a new colleague I met during a company orientation event. Upon first encountering this individual, I immediately formed a negative impression. They appeared distant, aloof, and disinterested in participating in the activities. Their body language and limited interactions conveyed a sense of superiority and a lack of interest in getting to know others. Consequently, I felt that this person may be arrogant and difficult to work with in the future.

However, as time progressed, I discovered that my initial impression was remarkably inaccurate. Through subsequent interactions during team projects and informal conversations, I realized that this person had a shy and introverted personality. Moreover, their behavior in the orientation event was a result of feeling overwhelmed in a new environment rather than being disinterested or arrogant. This experience taught me the importance of not jumping to conclusions based solely on initial encounters.

Social Psychology Theory Explanation:

Social psychology offers valuable insights into understanding the phenomenon of misjudging someone based on first impressions. The two theories that can shed light on this situation are the Attribution Theory and the Primacy Effect.

The Attribution Theory, proposed by Fritz Heider, explores how people make sense of others’ behavior by attributing it to either internal or external causes. When forming a first impression, we tend to make internal attributions, assuming that someone’s behavior is caused by their personality or disposition. In the case of my initial impression of the colleague, I wrongly attributed their behavior to arrogance, failing to consider any alternative explanations. This demonstrates how our tendency to make internal attributions can lead us astray and result in mistaken first impressions.

The Primacy Effect, on the other hand, refers to the cognitive bias in which the information we encounter first has a more significant impact on our overall impression. In the context of meeting someone for the first time, the initial information we receive, such as appearance and behavior, holds greater weight in forming our judgment compared to later information. In my personal experience, my negative first impression of the colleague heavily influenced my perception of them, making it difficult for me to see past that initial impression. This illustrates how the Primacy Effect can contribute to the persistence of mistaken first impressions.

Furthermore, social psychology emphasizes the role of individual differences and situational factors in shaping our perceptions and judgments. Personality traits, such as introversion or shyness, can significantly impact how individuals present themselves in social situations. Someone who is introverted may appear distant or uninterested, causing a misinterpretation of their intentions or personality. Understanding and considering these individual differences can help in avoiding the trap of forming inaccurate initial impressions.


In conclusion, my personal experience of being certain about my first impression of someone but later realizing my mistake highlights the fallibility of first impressions. Social psychology theories, such as the Attribution Theory and the Primacy Effect, provide insights into why this phenomenon occurs. Firstly, the tendency to make internal attributions and overlook alternative explanations can lead to mistaken judgments. Secondly, the Primacy Effect demonstrates how initial information strongly influences our overall impressions. Finally, the consideration of individual differences and situational factors is crucial in understanding others accurately. Recognizing the potential for misjudgment based on first impressions can help us become more open-minded and refrain from forming premature conclusions about others.
