An Introduction to the Theory of Reasoned Action

One psychological theory that can shed light on consumer decision-making is the Theory of Reasoned Action. This theory provides insights into why consumers make the choices they do by examining their attitudes, beliefs, and intentions.

Key Principles of the Theory of Reasoned Action

The Theory of Reasoned Action, developed by Martin Fishbein and Icek Ajzen in the late 1960s, proposes that an individual’s behavior is determined by their intentions, which in turn are influenced by their attitudes and subjective norms.

Attitudes refer to an individual’s positive or negative evaluation of a behavior, while subjective norms are the perceived social pressures to engage or not engage in a behavior.

According to this theory, attitudes and subjective norms combine to shape an individual’s behavioral intention. This intention, in turn, guides their actual behavior.

For example, if an individual has a positive attitude towards buying organic products and believes that their friends and family also support this behavior, they are more likely to intend to buy organic products and follow through with the purchase.

Components of the Theory of Reasoned Action

The Theory of Reasoned Action (TRA) is a social psychology and behavioral science theory that was developed to understand and predict human behavior, particularly in the context of decision-making.

The central premise of the Theory of Reasoned Action is that human behavior is driven by rational decision-making based on attitudes, subjective norms, and behavioral intentions.

Here are the key components of the theory:

Attitudes (A)

Attitudes refer to an individual’s overall evaluation or assessment of performing a specific behavior. This assessment is influenced by beliefs about the consequences of the behavior and the perceived value or desirability of those consequences. Attitudes can be positive (favorable) or negative (unfavorable) toward the behavior in question.

Subjective Norms (SN)

Subjective norms represent the social influences and perceived societal expectations related to a specific behavior. It includes the influence of friends, family, peers, and society at large.

Subjective norms reflect whether an individual perceives that others important to them think they should or should not engage in the behavior.

Behavioral Intentions (BI)

Behavioral intentions are a person’s motivation and willingness to perform a particular behavior. They are influenced by both attitudes and subjective norms.

In other words, behavioral intentions result from a combination of the individual’s personal evaluation of the behavior (attitudes) and their perception of what others expect them to do (subjective norms).

Behavior (B)

Behavior is the actual action or conduct of the individual. It is the outcome of the individual’s intentions and is influenced by their attitudes and subjective norms.

The Theory of Reasoned Action posits that these components are interconnected. Attitudes and subjective norms influence an individual’s behavioral intentions, which, in turn, shape their actual behavior.

The theory assumes that individuals are rational decision-makers who consider the consequences of their actions and the social pressures they experience when deciding whether to engage in a behavior.

The Theory of Reasoned Action has been influential in various fields, especially in understanding and predicting behaviors related to health, consumer choices, and social issues.

It has provided a framework for designing interventions and persuasive communication strategies that aim to change attitudes and subjective norms to influence behavioral intentions and, ultimately, behavior.

It’s worth noting that the Theory of Reasoned Action was later extended and refined into the Theory of Planned Behavior (TPB) by adding the concept of perceived behavioral control, which accounts for factors beyond an individual’s control that may influence behavior.

Theory of Reasoned Action vs. Theory of Planned Behavior

While the Theory of Reasoned Action provides valuable insights into consumer decision-making, it is important to distinguish it from the Theory of Planned Behavior (TPB). The TPB, also developed by Fishbein and Ajzen, expands on the Theory of Reasoned Action by incorporating an additional factor: perceived behavioral control.

Perceived behavioral control refers to an individual’s belief in their ability to perform the behavior. This factor recognizes that intention alone may not always translate into actual behavior if external factors hinder the individual’s ability to act.

For example, someone may have the intention to exercise regularly but may not be able to do so due to their busy schedule or lack of access to a gym.

 Here are the core components of TPB:

  1. Attitudes (A): Similar to TRA, attitudes in TPB represent an individual’s overall evaluation or assessment of performing a specific behavior. These attitudes are influenced by beliefs about the consequences of the behavior and the perceived desirability of those consequences. Attitudes can be positive or negative toward the behavior.
  2. Subjective Norms (SN): Subjective norms, like in TRA, refer to the social influences and perceived societal expectations related to a specific behavior. This includes the influence of friends, family, peers, and society at large. Subjective norms reflect whether an individual perceives that others important to them think they should or should not engage in the behavior.
  3. Behavioral Intentions (BI): Behavioral intentions are the individual’s motivation and willingness to perform a particular behavior. They result from a combination of attitudes and subjective norms, just like in TRA. Behavioral intentions represent the individual’s plan to engage in the behavior.
  4. Perceived Behavioral Control (PBC): Perceived behavioral control is the new component introduced in TPB. It reflects the individual’s perception of their ability to perform the behavior. It considers factors that may facilitate or hinder the behavior, such as self-efficacy, resources, skills, and external barriers.
  5. Behavior (B): Behavior is the actual action or conduct of the individual. It is influenced by behavioral intentions, attitudes, subjective norms, and perceived behavioral control. In TPB, perceived behavioral control acts as a direct determinant of behavior, in addition to its indirect influence through intentions.

The Theory of Planned Behavior emphasizes the idea that while attitudes and subjective norms shape behavioral intentions, perceived behavioral control directly affects the behavior itself.

In situations where individuals perceive a high level of control over a behavior, their intentions are more likely to translate into actual behavior.

TPB is particularly valuable in understanding complex behaviors and in designing interventions or strategies to change behavior.

It acknowledges that individuals may have positive intentions but may not be able to carry out the behavior due to external constraints or low self-efficacy. This recognition of the role of perceived control enhances the predictive power of the theory.

Applying TRA and TPB in Marketing

The Theory of Reasoned Action (TRA) and the Theory of Planned Behavior (TPB) are valuable frameworks for understanding and influencing consumer behavior in marketing. These theories provide insights into the factors that drive purchasing decisions and offer practical guidance for marketers.

Here’s how TRA can be applied in marketing:

1. Assessing Consumer Attitudes:

Marketers can conduct surveys and research to understand consumers’ attitudes toward products or brands. By identifying favorable and unfavorable attitudes, they can tailor marketing messages to reinforce positive perceptions or address concerns.

2. Leveraging Social Influence:

Subjective norms highlight the impact of peer and societal influence. Marketers can utilize social proof, testimonials, and endorsements from influencers or satisfied customers to create a positive social norm around their products or services.

3. Influencing Behavioral Intentions:

Marketers aim to influence consumers’ intentions to purchase. This can be achieved through persuasive advertising, promotions, and communication strategies that align with consumers’ attitudes and social norms.

Here’s how TPB can be applied in marketing:

4. Addressing Perceived Control:

Marketers should consider factors that may hinder or facilitate consumer actions. For example, if convenience is a barrier, brands can offer easy online purchasing options or streamlined checkout processes to enhance consumers’ perceived control.

5. Enhancing Self-Efficacy:

Self-efficacy, or an individual’s belief in their ability to perform a behavior, is crucial. Marketers can build confidence in consumers by providing user-friendly product instructions, tutorials, or customer support, reducing the perceived difficulty of using a product.

6. Tailoring Marketing Messages:

Marketing messages should align with consumers’ perceived control and self-efficacy. For instance, if promoting a fitness product, marketers can highlight its ease of use and suitability for individuals at different fitness levels.

Both TRA and TPB offer practical implications for marketers:

7. Segmenting Audiences:

Marketers can segment audiences based on their attitudes, subjective norms, and perceived control. Tailored marketing campaigns can be developed for each segment to maximize effectiveness.

8. Persuasive Messaging:

Understanding the factors influencing behavioral intentions allows marketers to create persuasive messaging that resonates with consumers. Messages can address attitudes, social norms, and control factors simultaneously.

9. Behavior Prediction:

By assessing behavioral intentions, marketers can predict future actions of consumers. This can inform inventory management, product launches, and demand forecasting.

10. Feedback and Adaptation:

Marketers should collect feedback from customers to continuously adapt their strategies. Monitoring changes in attitudes, subjective norms, and perceived control helps in refining marketing approaches.

Q2: How does TRA differ from TPB?

A2: TRA does not include perceived behavioral control, while TPB incorporates it as an additional factor. TPB recognizes the role of perceived control in directly influencing behavior.

Q3: What are “attitudes” in TRA?

A3: Attitudes in TRA refer to an individual’s overall evaluation or assessment of performing a specific behavior. They are influenced by beliefs about the consequences of the behavior and perceived desirability.

Q4: What is the Theory of Planned Behavior (TPB)?

A4: TPB is an extension of TRA that adds the concept of perceived behavioral control. It explains how attitudes, subjective norms, perceived control, and intentions collectively influence human behavior.

Q5: What is “perceived behavioral control” in TPB?

A5: Perceived behavioral control in TPB reflects an individual’s perception of their ability to perform a behavior. It considers factors like self-efficacy and external barriers that may facilitate or hinder the behavior.

Q6: How can TPB be applied in practice?

A6: TPB can be used to design interventions and strategies for behavior change. By understanding and addressing factors influencing attitudes, norms, and perceived control, organizations can promote desired behaviors.

Q7: Which theory is more comprehensive for predicting behavior?

A7: TPB is considered more comprehensive than TRA because it includes perceived behavioral control as a direct determinant of behavior. It recognizes that intentions alone may not guarantee action.
