Sternberg’s Triangular Theory of Love | Overview & Types

Posted on February 23, 2025 by Rodrigo Ricardo

Love is one of the most complex and multifaceted human emotions, often difficult to define or explain in simple terms. From romantic relationships to familial bonds, love exists in many forms, and it can be experienced and expressed in various ways. One influential theory that seeks to explain love is Sternberg’s Triangular Theory of Love, which was proposed by psychologist Robert Sternberg in 1986. According to this theory, love can be understood through three key components: intimacy, passion, and commitment. These components combine in different ways to create various types of love relationships.

This article delves into Sternberg’s Triangular Theory of Love, its components, the different types of love it describes, and how it contributes to our understanding of human relationships.

What is Sternberg’s Triangular Theory of Love?

Sternberg’s Triangular Theory of Love offers a comprehensive framework to understand the multifaceted nature of love, emphasizing that love is not a singular feeling but rather a combination of three essential components: intimacy, passion, and commitment. These components interact in various ways, creating different types of love experiences that can evolve over time. Sternberg’s model suggests that the presence and balance of these three components determine the depth and quality of romantic relationships, from passionate infatuation to deep, enduring companionship.

1. Intimacy

Intimacy is the emotional aspect of love, characterized by feelings of closeness, warmth, and a deep sense of connection. It involves sharing personal thoughts, emotions, experiences, and vulnerabilities with a partner. Intimacy goes beyond mere friendship; it encompasses a bond that fosters trust, mutual understanding, and emotional support.

In relationships where intimacy is strong, partners are comfortable with each other, feel safe in expressing their needs, and are often able to predict each other’s responses. This level of closeness nurtures emotional security and creates a foundation for a satisfying relationship. Intimacy doesn’t necessarily imply physical attraction but rather an emotional closeness that allows partners to be vulnerable and authentic with one another.

2. Passion

Passion represents the physical and emotional energy that ignites romantic and sexual attraction. It is the driving force behind romantic relationships, often manifesting as intense physical desire, sexual attraction, and longing. Passion fuels the excitement and exhilaration that accompany the early stages of a relationship when individuals are discovering and exploring each other’s desires.

Passion is frequently the most intense at the beginning of a relationship but can fluctuate over time. While it can be sustained through deliberate effort, passion may wane if not actively nurtured. Passion is often linked to physical proximity and the emotional highs that arise from moments of connection, whether in sexual encounters or shared moments of emotional intensity.

However, passion can sometimes be fleeting, and it often changes in intensity based on the evolving dynamics of the relationship. Relationships that rely heavily on passion may experience challenges if this component diminishes, unless intimacy and commitment are also present to sustain the connection.

3. Commitment

Commitment is the cognitive and behavioral aspect of love, signifying the decision to maintain a long-term relationship despite challenges or changing circumstances. It involves dedication and the intention to work through difficulties, fostering a sense of stability and security in the relationship. Commitment helps partners navigate both the highs and lows, ensuring that they remain engaged in the relationship and prioritize each other’s well-being.

In Sternberg’s theory, commitment can take various forms, from short-term decisions to stay together through a rough patch, to long-term commitments that involve planning a future together. Commitment is what ensures that a relationship endures, even when passion or intimacy may fluctuate. It’s often the component that provides the foundation for lasting love, as partners choose to stay committed to their bond, despite challenges that might arise.

Types of Love in Sternberg’s Theory

Sternberg’s Triangular Theory of Love outlines the three core components of love—intimacy, passion, and commitment—and how they can combine in different ways to create distinct types of love. According to Sternberg, these components can shift and evolve over time as a relationship progresses. Below is an expanded explanation of each love type in his theory.

1. Liking

Liking represents a type of love where there is a high degree of intimacy but low passion and commitment. It is typically found in platonic friendships, where individuals share mutual respect, understanding, and enjoy spending time together, but without any romantic or sexual attraction. In this type of relationship, emotional closeness is prominent, but there is no desire for long-term commitment or physical affection. While liking can be a solid and fulfilling form of affection, it is not characterized by the intensity that comes with other types of love.

2. Infatuation

Infatuation is love marked by intense passion but lacking in both intimacy and commitment. This form of love is usually described as superficial or fleeting, often sparked by strong physical attraction or sexual chemistry. While the experience of infatuation can feel overwhelming and all-consuming, it typically fades once the initial excitement or novelty of the attraction wears off. It’s often associated with the early stages of a romantic relationship and may not evolve into a deeper emotional connection, leaving the relationship short-lived unless it develops further.

3. Empty Love

Empty love features high commitment but low intimacy and passion. It often arises when individuals remain in a relationship for reasons beyond love—such as societal expectations, familial obligations, or financial stability. While the commitment to each other remains intact, emotional intimacy and physical attraction may be absent. Empty love can occur in long-term relationships that have become routine or stale, where partners honor their commitment to each other without nurturing the emotional or romantic aspects of the relationship. Though stable, empty love lacks the emotional fulfillment and deep connection that come with other types of love.

4. Romantic Love

Romantic love is characterized by a balance of passion and intimacy, but it lacks commitment. In romantic love, both partners feel emotionally connected and are physically attracted to one another, but they may not yet be ready to make a lasting commitment to the relationship. This type of love is often present during the early stages of romance, where the connection is deep but there might still be hesitancy about long-term plans. While romantic love can be thrilling and fulfilling, it may not last unless commitment is introduced over time.

5. Companionate Love

Companionate love consists of intimacy and commitment but lacks passion. It is often observed in long-term relationships, such as marriages or close friendships, where partners share a strong emotional bond and are committed to each other’s well-being. However, the physical attraction or romantic feelings may have diminished over time. Companionate love is the foundation for enduring relationships built on trust, mutual care, and companionship. While passion may fade, the connection that comes from shared memories, mutual support, and emotional closeness often remains strong.

6. Fatuous Love

Fatuous love involves a combination of passion and commitment, but it lacks intimacy. In this type of love, partners may rush into a commitment, often driven by intense passion or infatuation, without taking the time to build a deeper emotional connection. Fatuous love can lead to impulsive decisions, such as entering a relationship or marriage without thoroughly understanding each other. Despite its initial intensity, this form of love can be unstable, as the lack of intimacy and emotional depth may undermine the relationship in the long run.

7. Consummate Love

Consummate love is considered the ideal form of love in Sternberg’s theory. It involves the full presence of all three components: intimacy, passion, and commitment. In consummate love, both partners experience a deep emotional connection, strong physical attraction, and a desire to maintain the relationship for the long term. This type of love is often seen as the pinnacle of romantic relationships, where all the elements of love come together in harmony. However, consummate love requires ongoing effort and nurturing from both partners to sustain the balance of intimacy, passion, and commitment over time.

8. Non-Love

Non-love is the absence of intimacy, passion, and commitment. It describes relationships where there is no emotional connection, no physical attraction, and no commitment. Non-love can occur in casual interactions or acquaintanceships that are not meant to develop into anything deeper. These relationships serve functional purposes, such as fulfilling social or professional roles, but they do not fit the definition of love. Non-love is a type of relationship where all three components of Sternberg’s theory are missing.

In summary, Sternberg’s theory highlights the various ways love can manifest in relationships, with different combinations of intimacy, passion, and commitment. Over time, these components can shift, and relationships can evolve through these various stages of love. Understanding these types helps illuminate how love works in the context of human relationships, from fleeting infatuations to lasting, committed partnerships.

The Evolution of Love

Sternberg’s Triangular Theory of Love provides a framework for understanding how love can transform and develop over time. According to this theory, love consists of three core components: intimacy, passion, and commitment. As relationships evolve, the balance between these components can shift, leading to different types of love at various stages.

For instance, in the early stages of a relationship, infatuation might dominate. This type of love is characterized by high passion but low levels of intimacy and commitment. It’s intense, driven by attraction and desire, but lacks deep emotional connection or long-term plans. Over time, as intimacy and emotional closeness grow, passion and excitement might still be present, but the relationship could evolve into romantic love. Romantic love is defined by strong emotional bonds and intimacy, though it may still lack the firm commitment necessary for a lasting partnership.

As a relationship matures, it can progress further into companionate love. This type of love is characterized by deep emotional connection and strong commitment, but it may not be as intensely passionate as in the earlier stages. Over time, partners may build a solid foundation of trust, respect, and mutual understanding, which fosters a lasting, supportive bond. In some cases, relationships that contain all three components—intimacy, passion, and commitment—reach the peak of Sternberg’s model, known as consummate love. This is considered the most complete form of love, where partners share a balanced combination of emotional closeness, passionate attraction, and long-term commitment.

However, love can also face challenges. If any of the three components are neglected or fade over time, the relationship may regress into another type of love. For example, empty love occurs when commitment is present, but passion and intimacy are lacking, often seen in long-term relationships that have become routine or stale. In the absence of all three components, a relationship might deteriorate into non-love, where partners have little emotional or physical connection.

The evolution of love, therefore, depends on how well partners nurture and maintain intimacy, passion, and commitment. Relationships that evolve and adapt, continuously working on strengthening these components, are more likely to thrive over time.

Conclusion

Sternberg’s Triangular Theory of Love provides a valuable framework for understanding the complexity of love and relationships. By breaking down love into its core components—intimacy, passion, and commitment—Sternberg offers a model that can help us identify the types of love we experience and the dynamics that shape our relationships.

Whether in friendships, romantic partnerships, or familial bonds, love is not a singular emotion but a blend of different feelings and behaviors. By recognizing how intimacy, passion, and commitment interact, individuals can better navigate their relationships and work toward the fulfillment and stability that characterize the most enduring and meaningful connections.
