Personality Definition

Personality, a central concept in psychology, refers to an individual’s characteristic and enduring patterns of feeling, thinking, and behaving. It represents the consistent and distinctive ways in which a person interacts with the world around them. Importantly, personality is not static but rather relatively stable over time, even though it can evolve and adapt in response to life experiences.

On the other hand, social behavior encompasses the range of an individual’s feelings, thoughts, and actions as they relate to other people and their social environment. It reflects how individuals navigate and respond to various social situations and interactions. These behaviors can include how someone communicates, their emotional responses in social settings, and their actions within groups or relationships.

The relationship between personality and social behavior is intertwined and reciprocal. Here’s how they are connected:

1. Predictive Power:

Understanding an individual’s personality provides valuable insights into how they are likely to engage in social situations. For example, someone with an extroverted and outgoing personality is more likely to initiate social interactions, participate in group activities, and exhibit sociable behavior. Conversely, a person with an introverted and reserved personality may prefer quieter, one-on-one interactions.

2. Behavioral Clues to Personality:

Observing an individual’s social behavior can offer important clues about their underlying personality traits. Patterns of social behavior, such as being consistently empathetic and supportive in interpersonal relationships, may suggest a person with agreeable and compassionate personality traits. Conversely, someone who tends to be competitive and assertive in social contexts may exhibit traits associated with high extraversion or dominance in their personality.

3. Influence and Reciprocity:

Personality and social behavior are not isolated entities but rather influence each other in an ongoing feedback loop. A person’s personality traits can shape their social behavior, and conversely, their social interactions and experiences can influence the development and expression of personality. For instance, someone with a naturally shy disposition may become more extroverted and outgoing through positive social interactions and experiences.

In summary, personality and social behavior are intimately connected facets of human psychology. Personality serves as the foundation that shapes how individuals engage with their social world, while social behavior provides a visible expression of an individual’s personality traits. This interplay between personality and social behavior underscores the complexity of human nature and highlights the importance of considering both aspects when seeking to understand and predict an individual’s responses and actions in various social contexts.

History and Background of Personality Research


The exploration of personality has a rich history that spans centuries, reflecting humanity’s enduring fascination with understanding the unique attributes that make each individual distinct. People have long sought to encapsulate the essence of personality through a multitude of descriptive terms, with nearly 20,000 English words available to delineate the nuances of human character. Words like “outgoing” or “shy,” “dominant” or “submissive,” and “conscientious” or “careless” are just a few examples of the diverse palette we use to paint portraits of personality.

This quest to decipher the intricacies of personality has led psychologists through a journey of classification and categorization. Throughout history, various attempts have been made to devise systems that can help us classify individuals based on their unique personalities. This endeavor has ancient roots, with the Greeks making an early foray into personality typology. They categorized individuals into four broad personality types based on the predominance of certain bodily fluids: cheerful, irritable, depressed, and unemotional.

In the more recent past, the study of personality ventured into the realm of somatotypes, where personality classifications were linked to three different body types. The endomorph was characterized as plump, jolly, and relaxed; the ectomorph as thin, anxious, and unsocial; and the mesomorph as muscular, confident, and active. These early classifications marked the initial steps in our understanding of personality diversity.

Raymond Cattell’s groundbreaking work introduced a more comprehensive framework for personality assessment, known as the 16 Personality Factors (16 PF). This system offered a means to classify individuals based on 16 distinct personality dimensions. These factors included warmth, reasoning (intelligence), emotional stability, dominance, liveliness, rule-consciousness, social boldness, sensitivity, vigilance (suspiciousness), abstractedness (imaginativeness), privateness, apprehension, openness to change, self-reliance, perfectionism, and tension. By assessing a person’s score on each factor, Cattell’s approach sought to provide a comprehensive view of an individual’s personality.

However, the most prevalent contemporary framework for understanding personality lies in the “Big Five” personality traits. These five traits—Extraversion, Neuroticism (emotional instability), Conscientiousness, Agreeableness, and Openness to Experience (open-mindedness)—condense the complexity of personality into a more manageable framework. Describing an individual’s personality across these five dimensions is believed to offer a holistic understanding of their character. For example, someone high in Extraversion is expected to be sociable and outgoing, while high Conscientiousness signifies a diligent and hardworking nature. Neuroticism points to a propensity for anxiety, while Agreeableness suggests a cooperative and compassionate disposition, and Openness to Experience indicates a proclivity for open-mindedness and curiosity.

Crucially, personality traits exert a significant influence on people’s behavior. Therefore, understanding an individual’s personality can provide valuable insights into their likely actions and reactions. For instance, someone characterized as highly extraverted is anticipated to thrive in social settings, while a person with a high Conscientiousness score is likely to excel in tasks that demand diligence and precision.

In essence, the study of personality is an ongoing exploration of the tapestry of human nature, weaving together the threads of our unique attributes and behaviors. With each new discovery and classification system, we move closer to unraveling the intricate and ever-evolving puzzle of personality, shedding light on what makes each of us wonderfully unique and complex.

Identifying Personality Variables

The development of contemporary personality classification systems, such as the Big Five and the 16 Personality Factors (16 PF), is a testament to the quest to distill the richness of human personality into manageable categories. These systems are constructed through a meticulous process that begins with the identification of the diverse array of words and adjectives that people employ to describe one another. Each of these words serves as a potential building block in our understanding of personality.

The initial step in constructing these systems involves organizing these individual descriptors into meaningful categories based on shared characteristics. These categories, termed personality traits or factors, represent the common threads that run through the words used to depict personality. For instance, the category of “Extraversion” encompasses words like outgoing, sociable, loud, confident, talkative, friendly, and more. It is important to note that these categories can also include descriptors that represent the opposite end of the spectrum; in the case of Extraversion, they might include words like quiet, shy, or unconfident, as someone can exhibit low levels of Extraversion.

To refine and simplify the complex web of personality descriptors, statistical techniques like factor analysis are employed. Factor analysis seeks to identify similarities among these categories and, where applicable, combines them into broader dimensions of personality. This process allows for the consolidation of numerous descriptors into a more concise and structured framework for characterizing individuals.

For instance, within the 16 PF system, categories like liveliness, social boldness, and privateness might be amalgamated into the overarching Big Five category of Extraversion. Similarly, the 16 PF categories of tension, apprehension, and (low) emotional stability could be merged to form the Big Five category of Neuroticism. This aggregation of descriptors simplifies the task of describing individuals, replacing the need for an extensive vocabulary with a concise set of dimensions.

In essence, these personality classification systems provide a language and framework for capturing the multifaceted nature of human personality. Rather than relying on an overwhelming array of 20,000 words to describe individuals, these systems distill personality into a more manageable set of traits, typically 16 or just 5 in the case of the Big Five. This streamlined approach not only enhances our ability to understand and communicate about personality but also provides a foundation for exploring the intricacies of human behavior, relationships, and individual differences.

Measuring Personality

Assessing an individual’s personality is a multifaceted endeavor, blending the art of introspection with the science of inquiry. Personality questionnaires, or inventories, are the primary tools employed to navigate the complex terrain of an individual’s character. These inventories consist of a series of questions, designed to probe a person’s feelings, preferences, and behaviors, offering valuable insights into the intricacies of their personality.

Typically, individuals are the primary respondents, providing self-reports about their own personality traits. They are presented with questions that relate to various aspects of their character. However, in some instances, people who are familiar with the individual being assessed, such as supervisors, friends, or family members, may also be called upon to provide their perspectives on the individual’s personality. These external observations can enrich the understanding of an individual’s personality, offering a holistic view that combines self-perception with external viewpoints.

The process of constructing these questionnaires begins with the identification of two distinct groups known to differ in the personality trait under investigation. Members of both groups are then presented with a series of questions related to their feelings, preferences, and behaviors. The responses are carefully analyzed to identify which questions effectively discriminate between the two groups based on the specific trait being studied. These discriminating questions are subsequently incorporated into the personality inventory.

For instance, consider the development of a personality inventory aimed at measuring a person’s enjoyment of thinking. Researchers might administer the questionnaire to two groups with divergent characteristics, such as university professors and high-school dropouts. The expectation is that these groups would exhibit distinct levels of enjoyment in thinking. By examining the questions that generate differential responses between the two groups, researchers can select and include these questions in the final inventory.

Crucially, personality inventories can encompass a wide array of personality traits, each represented by its own distinct scale within the inventory. This multifaceted approach enables the measurement of various facets of an individual’s personality.

Accurate personality measurement is of paramount importance, as it serves as the linchpin for predicting and understanding human behavior. Without precise and reliable measures of personality, the influence of personality on social behavior can be underestimated, leading to incomplete and potentially inaccurate insights into an individual’s actions and interactions. Therefore, the art and science of personality measurement continue to play a pivotal role in unraveling the complex tapestry of human character and behavior.

Influence of Personality on Important Social Behaviors

The intricate relationship between personality and social behavior has long fascinated psychologists. By scrutinizing an individual’s responses on personality inventories and comparing them to observable social behaviors, researchers seek to uncover the extent to which personality traits can predict future actions and interactions. This pursuit has yielded valuable insights into the impact of personality on various critical social behaviors, including helping, conformity, obedience, aggression, and prejudice, among others. Notably, specific personality scales have been developed to assess people’s predispositions in these areas, offering a deeper understanding of how personality variables can shape our actions in society.

Let’s delve into a few examples to illustrate this intricate connection:

  1. Conformity and Apprehension: The category of apprehension within the 16 PF system can serve as a revealing indicator of an individual’s propensity toward conformity. People who experience higher levels of apprehension may be more inclined to conform to the decisions and preferences of others. Insecurity in one’s decision-making abilities can drive individuals to seek guidance from the consensus of the group, ultimately influencing their social behavior.
  2. Prejudice and Openness to Change/Dominance: Within the same system, the 16 PF categories of openness to change and dominance can be telling indicators of tendencies associated with a prejudiced personality. Individuals who exhibit a strong desire for dominance and are resistant to embracing novel ideas or breaking from conventional norms are more likely to harbor prejudiced attitudes. This inflexibility can shape their interactions with others and influence their social behavior.
  3. Helping Behavior and Warmth/Sensitivity: In the realm of helping behavior, the 16 PF categories of warmth and sensitivity come to the forefront. These traits are indicative of individuals who are attuned to the needs and emotions of others. Those high in warmth and sensitivity are more likely to engage in acts of altruism, extending a helping hand to those in need. Their social behavior reflects a genuine concern for the well-being of others.

It’s important to note that a wide range of personality measures exists to gauge various personality variables and their potential impact on social behavior. While these measures provide valuable insights and predictive power to varying degrees, they offer a nuanced lens through which to examine the multifaceted interplay between personality and our interactions within society.

In sum, the study of personality’s influence on social behavior underscores the profound role our individual traits play in shaping how we navigate the social world. As researchers continue to unravel these complex connections, we gain a deeper appreciation for the myriad ways in which personality contributes to the tapestry of our social lives.

Importance of the Situation versus Personality

The interplay between personality and the situation in predicting behavior has been a topic of profound significance and enduring debate in psychology. While personality is thought to offer insights into predicting an individual’s behavior, it’s crucial to recognize that it does not provide a foolproof crystal ball for every situation. This inherent unpredictability stems from the fact that human behavior is often marked by inconsistency, and it is heavily influenced by the context or situation at hand. The dynamic interplay between personality and situation is encapsulated in the person-situation controversy, a discourse spanning two decades that delves into the nuanced factors at play.

Let’s delve into some key aspects of this complex relationship:

  1. The Influence of Personality: Personality is most likely to exert a pronounced influence on behavior when the situation lacks strong external pressures or demands that would otherwise dictate how an individual should behave. In such cases, an individual’s dominant personality traits tend to guide their actions. Moreover, when an individual places less importance on aligning their behavior with situational requirements, their personality traits become more salient in shaping their actions.
  2. Consistency Across Situations: Consistency in behavior across a variety of situations and over time is another hallmark of personality’s influence. When an individual consistently exhibits particular behaviors across diverse contexts, it suggests that their personality traits are integral to their behavioral repertoire. This consistency serves as a valuable indicator of the enduring impact of personality on behavior.
  3. Situational Influences: Conversely, the situation plays a pivotal role in shaping behavior when it exerts strong pressures or constraints on an individual. In situations where external factors or social norms are highly influential, an individual’s behavior may align more closely with the situational requirements, overriding the influence of their personality traits.
  4. Interaction Effects: It’s important to note that personality and situation often interact in intricate ways. The interplay between an individual’s unique personality and the specific demands of a situation can yield a spectrum of behavioral outcomes, making predictions a complex endeavor.

In essence, the person-situation controversy highlights that neither personality nor situation can be exclusively relied upon for predicting behavior. Instead, the interaction between these factors, coupled with the degree of consistency in an individual’s behavior across situations, shapes the complex landscape of human actions.

Understanding this delicate balance between personality and situation is essential for comprehending the intricate nuances of human behavior. It underscores the importance of recognizing that while personality provides valuable insights, it is the dynamic interplay with the situation that often defines the ultimate course of action.

Types of Situations

The influence of personality on behavior is a dynamic interplay with the situational context, and understanding the types of situations that exert greater or lesser influence is essential in predicting human actions. Here are some key insights into how personality and situations intersect to shape behavior:

  1. Unfamiliar and Formal Situations: In unfamiliar or formal situations, where individuals are required to adhere to specific social norms or conduct themselves formally (e.g., at church or during a job interview), personality tends to have a diminished impact on behavior. The situational demands take precedence, often guiding individuals’ actions more than their innate personality traits.
  2. Familiar and Comfortable Settings: Conversely, in familiar and comfortable settings, such as interactions with close friends or family, an individual’s personality is more likely to exert influence over their behavior. In these relaxed environments, people tend to be more themselves, allowing their personality traits to manifest more prominently.
  3. Behavioral Adaptability: It’s important to recognize that individuals possess a degree of behavioral adaptability. An individual who identifies as shy, for instance, may display outgoing and friendly behavior once they become comfortable in a social setting. This adaptability underscores the importance of considering both personality traits and situational factors when predicting behavior.
  4. Situational Variation: Situations can either amplify or attenuate personality traits. For example, a typically passive person may exhibit aggressive behavior when confronted with sufficient provocation. This situational variation can blur the lines between innate personality tendencies and situational influences.
  5. Experimental Research: Understanding the relative impact of personality and situations on behavior often requires carefully controlled experimental research. Researchers create distinct situations and expose participants to these scenarios, then observe and measure their behavior. Differences in behavior across situations provide insights into the role of the situation in shaping behavior.
  6. Personality-Situation Interaction: To disentangle the contributions of personality and situation, researchers may both measure personality using inventories and manipulate the situational context. This approach allows for a more nuanced understanding of whether an individual’s personality or the specific situation better predicts their behavior.

In essence, the influence of personality on behavior is context-dependent. While personality traits offer valuable insights into how individuals may behave, the situation in which they find themselves plays a pivotal role in shaping their actions. Recognizing the intricate interplay between personality and situations is essential for a comprehensive understanding of human behavior and its predictability.

Types of People and Personality Characteristics

Understanding how people vary in their responsiveness to different situations and how certain personality traits come to the forefront is crucial in unraveling the complexities of human behavior. Here are key insights into how individuals differ in their self-monitoring tendencies and the dominance of specific personality characteristics:

  1. High Self-Monitors vs. Low Self-Monitors: Individuals can be categorized as either high self-monitors or low self-monitors based on their propensity to adjust their behavior to align with the demands of different social situations.
    • High Self-Monitors: These individuals are adept at monitoring and adapting their behavior to suit the specific social context. They are more likely to exhibit different behaviors around different groups of people or in varying situations. For example, a high self-monitor might act reserved and professional at work but outgoing and relaxed among friends.
    • Low Self-Monitors: In contrast, low self-monitors are less concerned about conforming to situational expectations. They tend to behave consistently with their core personality traits across different situations. A low self-monitor may exhibit similar behavior regardless of the social context.
  2. Dominant Personality Characteristics: Within an individual’s overall personality profile, some traits are more dominant or pronounced than others. These dominant characteristics are more likely to influence the person’s behavior across a variety of situations.
    • Example: Consider an individual who is highly neurotic but only mildly outgoing. In this case, the dominant personality trait is neuroticism, leading the person to experience anxiety across various situations. However, the trait of extraversion (outgoingness) may only manifest in their behavior occasionally, depending on specific circumstances.
  3. Expressive vs. Weak Personality Traits: Personality traits can be categorized as either expressive or weak, depending on their consistency across individuals and situations.
    • Expressive Traits: These traits are strongly evident in an individual’s speech, gestures, and overall mannerisms. People with highly expressive personalities consistently display these traits, regardless of the situation. For instance, an individual with an animated personality might always communicate loudly with exaggerated hand gestures.
    • Weak Traits: Conversely, weak personality traits are more situation-dependent. Individuals with weak traits may vary their behavior based on the context, emphasizing certain characteristics when they seek to make a positive impression or conform to specific expectations.

Understanding these variations in self-monitoring tendencies and the dominance of personality characteristics provides valuable insights into how people navigate social situations and adapt their behavior. It underscores the dynamic interplay between personality and context, shedding light on the complexity of human behavior across diverse situations and social settings.

Types of Behaviors

To grasp the intricate interplay between personality and behavior, it is crucial to recognize that personality traits often provide a better prediction of how individuals typically act across various situations rather than in a specific context. Instead of assessing an individual’s behavior in isolation, it is more informative to evaluate their behavior averaged across numerous situations. Here are key insights into the relationship between personality and behavior:

  1. Generalized Patterns of Behavior: Personality traits offer insights into an individual’s generalized patterns of behavior that transcend specific situations. For instance, a person characterized as dishonest may not necessarily cheat on a particular school exam. However, over time and across various situations, individuals with this personality trait are more likely to engage in a range of dishonest behaviors, such as cheating in academic settings, evading taxes, or resorting to lies.
  2. Behavioral Consistency: Personality traits reflect enduring aspects of an individual’s character, influencing how they respond to different situations and challenges. While situational factors can lead to variability in behavior, the consistency of personality traits becomes evident when examining behavior across a multitude of contexts.
  3. Measuring Behavior: Accurate assessment of behavior is essential for understanding its relationship with personality. Effective measures of behavior should meet several criteria:
    • Multiple Raters: Behavior should be assessed through the input of multiple raters who have a comprehensive understanding of the individual. These raters can provide diverse perspectives on the person’s behavior.
    • Direct Observability: Observable and tangible aspects of behavior should be evaluated. This ensures that the behavior being measured is directly related to the specific personality characteristic of interest.
    • Variety of Situations: Behavior should be assessed across a range of situations and contexts. This approach helps capture how personality traits manifest in diverse scenarios and over time.
    • Longitudinal Assessment: To gain a comprehensive understanding of the relationship between personality and behavior, assessments should be conducted over an extended period. This longitudinal perspective allows for the examination of patterns and changes in behavior.

In summary, personality traits provide valuable insights into an individual’s typical patterns of behavior across various situations. While situational factors can influence behavior in the short term, personality traits reflect enduring characteristics that shape how individuals generally interact with the world around them. To explore the connection between personality and behavior effectively, it is crucial to employ robust measures of behavior, gather input from multiple raters, and consider behavior across diverse contexts and over time.


The intricate relationship between personality and behavior holds significant implications for understanding and predicting human actions. Here are key insights into these implications:

  1. Balanced Predictive Power: Research reveals that the strength of the relationship between personality and behavior is on par with the connection between the situation and behavior. This similarity means that both personality and situational factors are crucial for accurately predicting an individual’s behavior. Together, they provide a comprehensive view of why people act the way they do.
  2. Predictive Accuracy: Personality traits are more effective at predicting how individuals will generally behave across various situations rather than pinpointing behavior in specific contexts. The dynamic and variable nature of situations can exert a considerable influence on behavior, making generalized predictions from personality traits more reliable.
  3. Influence of Dominant Personality Traits: Dominant personality characteristics play a pivotal role in determining the extent to which personality influences behavior. When individuals exhibit pronounced personality traits, their behavior is more likely to align with those traits, even when situational factors come into play. These dominant traits act as consistent drivers of behavior.
  4. Situational Impact: The situational context also wields significant influence over behavior. In situations where clear social rules or strong situational requirements are present, behavior tends to be shaped more by the situation itself. Conversely, when situational demands are weak or individuals are less concerned about fitting into the situation, personality traits play a more prominent role in guiding behavior.
  5. Reciprocal Influence: Individuals are not passive recipients of situational influences; they actively choose and shape the situations they enter. Personality traits drive individuals toward particular types of situations that align with their dispositions. This selection process increases the likelihood that they will exhibit behaviors consistent with their personality traits. Moreover, their behavior can, in turn, influence the atmosphere and dynamics of the situations they are in.

In summary, understanding the interplay between personality and behavior offers valuable insights into human actions. While both personality traits and situational factors contribute to behavior, personality traits are more reliable indicators of generalized behavior across various situations. The dynamic interplay between personality and situations underscores the complexity of human behavior and the need for comprehensive models that consider both factors. Recognizing the reciprocal influence of individuals on their chosen situations adds depth to our understanding of how personality and behavior are intertwined.
