In the field of psychology, there are various theories that seek to explain and predict human behavior. One of the most influential theories in this area is the Theory of Reasoned Action, developed by Martin Fishbein and Icek Ajzen in the late 1970s. This theory has become a fundamental conceptual framework for understanding how and why people They make decisions and perform certain actions. Through the integration of beliefs, attitudes, and social norms, the Theory of Reasoned Action offers a systematic approach to predicting human behavior.
Origins and foundations of the Theory of Reasoned Action
The Theory of Reasoned Action is based on the premise that people are rational beings who carefully evaluate available information before making decisions. According to Fishbein and Ajzen, human behavior is influenced by two main components: attitudes toward the behavior and subjective norms. Attitudes represent the positive or negative evaluation that a person has towards a certain action, while subjective norms reflect the perception of social pressure or support that a person experiences to carry out said action.
Attitudes toward behavior
Attitudes toward behavior play a key role in the Theory of Reasoned Action. According to this theory, people are more likely to carry out an action if they have a favorable attitude toward it. These attitudes are formed through the evaluation of the beliefs that a person has about the expected results of the behavior in question. For example, if a person believes that exercising regularly will lead to better health and well-being, he or she is more likely to develop a positive attitude toward this behavior and, consequently, commit to exercising regularly.
Subjective norms
In addition to attitudes toward behavior, subjective norms play an important role in predicting behavior. Subjective norms reflect a person's perception of whether their loved ones, friends, or society in general support or disapprove of performing a certain action. For example, if a person believes that their family and friends value practicing healthy habits, they are more likely to adopt these habits as a result of perceived social pressure.

According to the Theory of Reasoned Action, the formation of an intention is a crucial step in the process that leads to the performance of a specific behavior. The intention to carry out an action is based on the combination of attitudes toward the behavior and subjective norms related to said action. When a person has a positive attitude toward a behavior and perceives strong social support to carry it out, he or she is more likely to form the intention to perform that action in the near future.
It is important to highlight that the Theory of Reasoned Action also recognizes the influence of external factors in the decision-making process. These factors may include time, resource, or information limitations, which may affect the relationship between attitudes, subjective norms, and the intention to carry out a specific action.
Applications of the Theory of Reasoned Action
Over the years, the Theory of Reasoned Action has been widely applied in various contexts, from public health to marketing and organizational management. This theory has proven to be especially useful in predicting and modifying behaviors related to health and well-being, such as the adoption of healthy eating habits, regular physical exercise, and adherence to medical treatments.
Public health
In the field of public health, the Theory of Reasoned Action has been used to design interventions aimed at promoting healthy behaviors in the population. By understanding the subjective beliefs, attitudes, and norms that influence people's decisions, health professionals can develop effective strategies to promote healthier lifestyles and prevent chronic diseases.
Marketing
In the field of marketing, the Theory of Reasoned Action has been applied to understand and predict consumer behavior. By analyzing customers' attitudes toward a specific product or service and the social norms that influence their purchasing decisions, companies can develop more effective marketing strategies aimed at their target audience.
Organizational management
In the field of organizational management, the Theory of Reasoned Action has been used to study the behavior of employees in the workplace. By identifying the attitudes and subjective norms that affect the productivity and commitment of workers, organizations can implement motivation and personal development programs that foster a more positive and productive work environment.
Criticisms and limitations of the Theory of Reasoned Action
Despite its wide application and relevance in the study of human behavior, the Theory of Reasoned Action has also been the subject of criticism and limitations. Some researchers have questioned the ability of this theory to explain the complexity and variability of human behavior, arguing that people's decisions may be influenced by emotional, contextual or unconscious factors that go beyond rational beliefs and social norms.
In addition, it has been pointed out that the Theory of Reasoned Action tends to overvalue the role of rationality in decision making, overlooking the influence of irrational or instinctive factors on human behavior. This critique suggests that emotions, impulses, and past experiences also play a significant role in the decisions people make in their daily lives.
Conclusions
In summary, the Theory of Reasoned Action offers a solid conceptual framework for understanding how beliefs, attitudes, and social norms influence decision making and the performance of specific behaviors. Through the integration of these components, this theory provides useful guidance for predicting human behavior in a variety of contexts and for designing effective interventions that promote positive changes in society.
Despite its limitations , the Theory of Reasoned Action continues to be a valuable tool for investigating and understanding the complexity of human behavior, and its application continues to be relevant in fields as diverse as psychology, public health, marketing and organizational management.
