The Elaboration Likelihood Model and Social Media

The Elaboration Likelihood Model (ELM) was developed in the 1980s by Richard E. Petty and John T. Cacioppo. It is a significant theory in the field of persuasion and attitude change.

Various translation terms have been used for this model in Turkish. While "Ayrıntılı İnceleme Olasılığı Modeli" (Detailed Examination Likelihood Model) is a translation that interprets the concept of "elaboration" as detailed examination, it is particularly common in the literature of communication and psychology. "Ayrıntılandırma Olasılığı Modeli" (Elaboration Likelihood Model) is another common variation that translates the concept of elaboration as "ayrıntılandırma." This translation is frequently encountered in academic articles and theses. "Detaylandırma Olasılığı Modeli" (Detailing Likelihood Model) is a translation that uses the word "detaylandırma" as a synonym for "ayrıntılandırma." Some sources refer to ELM as "Detaylandırma Olasılık Modeli." This usage is especially seen in marketing and advertising research. The term "Özümseme-Olabilirliği Modeli" (Assimilation Likelihood Model) is a rarer translation that interprets the concept of elaboration as assimilation (internalizing information). In this article, I will use the translation "Ayrıntılandırma Olasılığı Modeli."

Returning from how it is used in Turkish to what the model says, as we know, persuasion is directly related to our daily lives. People are persuaded when they learn something from the messages they read, listen to, or watch. We remember a message as ideas, and that is how we are persuaded. If we have not learned something, it is impossible for us to remember it, and therefore we are not persuaded by that message. However, learning does not always bring persuasion with it. For example, some social media advertisements or sponsored content may contain topics we do not like or are not interested in. When we do not want to see such content, we do not want to learn or remember the message, and as a result, we are not persuaded by that advertisement.

The Elaboration Likelihood Model explains how a persuasive message changes the attitude of the reader or viewer. It is an important model, especially in the fields of media, advertising, public relations, and marketing, because it is used to understand consumer attitudes and create marketing strategies. Persuasion is the process of guiding someone to take action on a subject through logical arguments or various strategies.

The Elaboration Likelihood Model suggests that every message goes through the persuasion process in two different ways. These paths are divided into two: the Central Route and the Peripheral Route. Both paths are effective persuasion techniques, but each relies on different mechanisms.

The central route is a direct and in-depth persuasion process. Persuasion that occurs through this path requires careful evaluation of the arguments contained in the message. The reader or viewer consciously analyzes the message and evaluates it from different perspectives. An individual processing a message via the central route focuses on the content of the message and must have the motivation and cognitive capacity to think about it. Simply put, the person must care about the message and truly think about the subject. Messages processed via the central route generally lead to longer-lasting and more robust attitude changes. However, the central route has a disadvantage: if the message recipient is not directly interested in the subject of the message or if its impact on them is low, they may ignore the message. For example, if a social media user is very interested in artificial intelligence and data security, they may carefully examine content they see on X (Twitter), LinkedIn, or YouTube, such as "10 Ways to Protect Your Personal Data." When this user reads the content, thinks about it in depth, analyzes the information presented, and evaluates how to apply it to their own life, the persuasion process takes place via the central route. On the other hand, a user who sees the same content but has no interest in data security may ignore or quickly scroll past this message.

The peripheral route is a more superficial persuasion process, and the content of the message is not consciously analyzed. Messages processed via this route rely on the recipient being influenced by persuasive side factors (visuals, brand image, celebrity endorsement, emotional associations, etc.) without fully understanding the message. Instead of dealing with the content in detail, the recipient of the message is persuaded through factors that catch their attention, such as visuals, popular people, or trends. For this reason, the peripheral route is frequently used in advertising, public relations, and marketing. Sometimes people do not have enough time or motivation to think about the content of the message. In such cases, they turn to the most striking or appealing option. For example, an Instagram user sees an ad for a new pair of headphones from a tech brand. However, they are not interested in the technical specifications or do not want to spend time understanding them. But if a famous influencer (for example, a popular YouTuber, a musician, or a beautiful woman) is wearing the headphones in the ad and says, "I use this product and I love it!", the user may be persuaded. Here, instead of analyzing the features of the headphones, the person may decide to buy the product based on the recommendation of a figure they like, trust, or find appealing. Similarly, an advertisement made through a popular trend or viral movement on TikTok can lead users to act without thinking. For example, a coffee brand can create a positive perception of its product by sharing videos where people drinking its coffee look more energetic and happy. The user may decide to try the coffee just because it is a fun video, without examining the content in detail.

Social media platforms reach large audiences by using both paths of persuasion. While informative content uses the central route, attention-grabbing and trend-focused content can influence viewers using the peripheral route. Brands, public relations experts, and digital media strategists determine which method will be more effective based on the interests of their target audience and shape their content accordingly. However, as a conscious social media consumer, if you at least know the ways in which you are being persuaded, you can realize it when they try to guide you through disinformation and manipulation. Otherwise, you may turn into a mass that is easily manipulated by believing everything you hear. You may get lost in the fake echo chambers of the digital world and fail to notice how the line between reality and fiction is erased. While your perceptions are being shaped by others, you may not even question whether your own thoughts truly belong to you. Worst of all, while you think you are in control, you may actually be trapped inside a narrative directed by others.
