Two-Step Flow Theory

The Two-Step Flow Theory, developed by Lazarsfeld and Katz, suggests that media messages primarily influence opinion leaders who then influence others through interpersonal communication. While it has practical applications, critics point out that it may oversimplify information flow in today’s digital age.

Defining the Two-Step Flow Theory

The Two-Step Flow Theory posits that mass media, such as newspapers, radio, and television, do not have a direct and immediate impact on individuals’ opinions and behaviors. Instead, the media influence opinion leaders or “opinion elites” who, in turn, influence the broader public. The theory suggests a two-step process of information dissemination and opinion formation:

  1. Step One – Media Influence Opinion Leaders: Initially, the mass media disseminate information and ideas to a select group of opinion leaders who actively consume and interpret the media content. Opinion leaders are individuals who are well-informed, politically active, and socially engaged. They often have a higher degree of education and are influential within their social networks.
  2. Step Two – Opinion Leaders Influence the Public: Opinion leaders, having digested and interpreted the media content, engage in discussions and interactions with members of their social networks, including family, friends, and colleagues. They share their opinions, interpretations, and recommendations, thereby influencing the attitudes and behaviors of those around them.

In essence, the Two-Step Flow Theory posits that the primary influence of mass media is indirect, mediated through opinion leaders who serve as intermediaries between the media and the general public.

Key Concepts of the Two-Step Flow Theory

To understand the Two-Step Flow Theory more comprehensively, let’s explore some key concepts:

1. Opinion Leaders

Opinion leaders are central to the theory. They are individuals who are recognized and respected within their social networks for their expertise and credibility in specific domains, such as politics, culture, or consumer products. Opinion leaders actively seek out and consume media content and play a crucial role in shaping the opinions and attitudes of others.

2. Selective Exposure

Selective exposure refers to the tendency of individuals to choose media content that aligns with their existing beliefs and preferences. Opinion leaders are less affected by selective exposure, as they engage with a broader range of media sources and content. This exposure enables them to gather diverse information and form informed opinions.

3. Two-Step Flow

The two-step flow represents the process through which media influence is mediated by opinion leaders. It underscores the idea that individuals are more likely to be influenced by the opinions and recommendations of their peers and trusted opinion leaders than by direct exposure to media messages.

Relevance in the Digital Age

While the Two-Step Flow Theory was developed in an era dominated by traditional mass media, its principles remain relevant in today’s digital age. Several factors highlight its continued significance:

1. Social Media and Online Communities

Social media platforms have become hubs for information sharing and opinion formation. Opinion leaders on these platforms can have a significant impact on shaping public discourse and influencing their followers.

2. User-Generated Content

The rise of user-generated content platforms, such as blogs, vlogs, and review sites, has amplified the role of opinion leaders. Individuals who create content and build dedicated online communities often serve as opinion leaders in niche areas of interest.

3. Viral Information Spread

Information and content can go viral on social media, with opinion leaders often playing a pivotal role in amplifying and disseminating such content. Their endorsements and shares can lead to widespread attention and influence.

4. Personalized Recommendations

Online algorithms and recommendation systems often use data on users’ preferences and behaviors to provide personalized content recommendations. Opinion leaders can have a profound impact on the content that reaches their followers through these systems.

Practical Insights into the Dynamics of Influence

Understanding the Two-Step Flow Theory can offer practical insights for individuals, organizations, and policymakers in navigating the complex landscape of media and influence:

1. Identifying Opinion Leaders

Identifying opinion leaders in specific domains or communities can be valuable for targeted communication and outreach efforts. Collaborating with opinion leaders can help amplify messages and gain credibility.

2. Building Relationships

Building relationships with opinion leaders can foster trust and cooperation. Engaging with opinion leaders in meaningful ways, such as seeking their input or involving them in initiatives, can lead to mutually beneficial outcomes.

3. Evaluating Media Impact

When assessing the impact of media campaigns or content dissemination strategies, it is essential to consider the role of opinion leaders and their influence on the target audience.

4. Promoting Media Literacy

Promoting media literacy and critical thinking skills is crucial for individuals to discern reliable information sources and navigate the influence of opinion leaders effectively.

5. Addressing Echo Chambers

The concept of selective exposure highlights the risk of echo chambers, where individuals only engage with content and opinions that reinforce their existing beliefs. Encouraging diverse media consumption can mitigate this risk.


The Two-Step Flow Theory offers a valuable perspective on the dynamics of influence in communication and media. It reminds us that media influence is not a one-way street but a complex interplay of information dissemination and opinion formation. In an era where information spreads rapidly through digital networks and social media, understanding the role of opinion leaders and the two-step flow of influence remains essential for comprehending how ideas and attitudes are shaped and shared. By recognizing the intermediaries who mediate media influence, we gain insights into the intricate web of human communication and the power of social networks in shaping our collective understanding of the world.

Key highlights of the Two-Step Flow Theory:

  • Indirect Media Influence: The theory suggests that media influence operates indirectly through opinion leaders who filter, interpret, and share media content with others.
  • Opinion Leaders: Opinion leaders are individuals who are knowledgeable in specific domains and act as intermediaries between mass media and the general public.
  • Selective Exposure: People tend to consume media content that aligns with their preexisting beliefs and interests, emphasizing the role of opinion leaders in introducing diverse perspectives.
  • Social Networks: The theory underscores the importance of social networks and interpersonal relationships in the flow of information.
  • Implications for Marketing: Identifying and targeting opinion leaders can be an effective marketing strategy to reach wider audiences.
  • Word-of-Mouth Marketing: The theory highlights the power of word-of-mouth marketing, with opinion leaders playing a significant role in influencing consumer opinions.
  • Challenges and Criticisms: Critics argue that the theory simplifies communication processes, lacks precision in defining opinion leaders, and may not fully account for the complexities of modern media environments.
  • Real-World Applications: The Two-Step Flow Theory is observed in various real-world contexts, including political campaigns, product recommendations, social media influencers, health information sharing, news dissemination, and entertainment preferences.

Connected Communication Models

Aristotle’s Model of Communication

The Aristotle model of communication is a linear model with a focus on public speaking. The Aristotle model of communication was developed by Greek philosopher and orator Aristotle, who proposed the linear model to demonstrate the importance of the speaker and their audience during communication

Communication Cycle

The linear model of communication is a relatively simplistic model envisaging a process in which a sender encodes and transmits a message that is received and decoded by a recipient. The linear model of communication suggests communication moves in one direction only. The sender transmits a message to the receiver, but the receiver does not transmit a response or provide feedback to the sender.

Berlo’s SMCR Model

Berlo’s SMCR model was created by American communication theorist David Berlo in 1960, who expanded the Shannon-Weaver model of communication into clear and distinct parts. Berlo’s SMCR model is a one-way or linear communication framework based on the Shannon-Weaver communication model.

Helical Model of Communication

The helical model of communication is a framework inspired by the three-dimensional spring-like curve of a helix. It argues communication is cyclical, continuous, non-repetitive, accumulative, and influenced by time and experience.

Lasswell Communication Model

The Lasswell communication model is a linear framework for explaining the communication process through segmentation. Lasswell proposed media propaganda performs three social functions: surveillance, correlation, and transmission. Lasswell believed the media could impact what viewers believed about the information presented.

Modus Tollens

Modus tollens is a deductive argument form and a rule of inference used to make conclusions of arguments and sets of arguments.  Modus tollens argues that if P is true then Q is also true. However, P is false. Therefore Q is also false. Modus tollens as an inference rule dates back to late antiquity where it was taught as part of Aristotelian logic. The first person to describe the rule in detail was Theophrastus, successor to Aristotle in the Peripatetic school.

Five Cannons of Rhetoric

The five canons of rhetoric were first organized by Roman philosopher Cicero in his treatise De Inventione in around 84 BC. Some 150 years later, Roman rhetorician Quintilian explored each of the five canons in more depth as part of his 12-volume textbook entitled Institutio Oratoria. The work helped the five canons become a major component of rhetorical education well into the medieval period. The five canons of rhetoric comprise a system for understanding powerful and effective communication.

Communication Strategy

A communication strategy framework clarifies how businesses should communicate with their employees, investors, customers, and suppliers. Some of the key elements of an effective communication strategy move around purpose, background, objectives, target audience, messaging, and approach.

Noise if Communication

Noise is any factor that interferes with or impedes effective communication between a sender and receiver. When noise disrupts the communication process or prevents the transmission of information, it is said to be communication noise.

7 Cs of Communication

The 7Cs of communication is a set of guiding principles on effective communication skills in business, moving around seven principles for effective business communication: clear, concise, concrete, correct, complete, coherent, and courteous.

Transactional Model of Communication

The transactional model of communication describes communication as a two-way, interactive process within social, relational, and cultural contexts. The transactional model of communication is best exemplified by two models. Barnlund’s model describes communication as a complex, multi-layered process where the feedback from the sender becomes the message for the receiver. Dance’s helical model is another example, which suggests communication is continuous, dynamic, evolutionary, and non-linear.

Horizontal Communication

Horizontal communication, often referred to as lateral communication, is communication that occurs between people at the same organizational level. In this context, communication describes any information that is transmitted between individuals, teams, departments, divisions, or units.

Communication Apprehension

Communication apprehension is a measure of the degree of anxiety someone feels in response to real (or anticipated) communication with another person or people.

Closed-Loop Communication

Closed-loop communication is a simple but effective technique used to avoid misunderstandings during the communication process. Here, the person receiving information repeats it back to the sender to ensure they have understood the message correctly. 

Grapevine In Communication

Grapevine communication describes informal, unstructured, workplace dialogue between employees and superiors. It was first described in the early 1800s after someone observed that the appearance of telegraph wires strung between transmission poles resembled a grapevine.

ASE Model

The ASE model posits that human behavior can be predicted if one studies the intention behind the behavior. It was created by health communication expert Hein de Vries in 1988. The ASE model believes intention and behavior are determined by cognitive variables such as attitude, social influence, and self-efficacy. The model also believes that intention predicts behavior such that one’s attitude toward a behavior is influenced by the consequences of that behavior. Three cognitive variables are the primary determinants of whether the intention to perform a new behavior was sustained: attitude, social influence, and self-efficacy. Various external variables also influence these factors.

Integrated Marketing Communication

Integrated marketing communication (IMC) is an approach used by businesses to coordinate and brand their communication strategies. Integrated marketing communication takes separate marketing functions and combines them into one, interconnected approach with a core brand message that is consistent across various channels. These encompass owned, earned, and paid media. Integrated marketing communication has been used to great effect by companies such as Snapchat, Snickers, and Domino’s.

Social Penetration Theory

Social penetration theory was developed by fellow psychologists Dalmas Taylor and Irwin Altman in their 1973 article Social Penetration: The Development of Interpersonal Relationships. Social penetration theory (SPT) posits that as a relationship develops, shallow and non-intimate communication evolves and becomes deeper and more intimate.

Hypodermic Needle

The hypodermic needle theory was first proposed by communication theorist Harold Lasswell in his 1927 book Propaganda Technique in the World War. The hypodermic needle theory is a communication model suggesting media messages are inserted into the brains of passive audiences.

7-38-55 Rule

The 7-38-55 rule was created by University of California psychology professor Albert Mehrabian and mentioned in his book Silent Messages.  The 7-38-55 rule describes the multi-faceted way in which people communicate emotions, claiming that 7% of communication occurred via spoken word, 38% through tone of voice, and the remaining 55% through body language.

Active Listening

Active listening is the process of listening attentively while someone speaks and displaying understanding through verbal and non-verbal techniques. Active listening is a fundamental part of good communication, fostering a positive connection and building trust between individuals.
