Who are the liars who believe their own lies?


Deception is an age-old human behavior that has been studied extensively by psychologists and sociologists. It is fascinating to explore the complexities of lying and the individuals who not only deceive others but also convince themselves of their own falsehoods. In this article, we will delve into the concept of self-deception, examine the characteristics of individuals who engage in this behavior, and explore the psychological mechanisms underlying their ability to believe their own lies.

The Nature of Self-Deception

Self-deception refers to the act of deceiving oneself, often by distorting or ignoring evidence and rationalizing one’s own beliefs or actions. It is a psychological defense mechanism that allows individuals to maintain a positive self-image, protect their ego, and avoid cognitive dissonance.

1. The Motivations Behind Self-Deception

Self-deception can stem from various motivations, including:

  • Preserving self-esteem
  • Avoiding accountability
  • Justifying unethical behavior
  • Seeking social acceptance
  • Alleviating cognitive dissonance

These motivations often intertwine and can vary depending on the individual and the specific situation.

2. Characteristics of Individuals Engaging in Self-Deception

While anyone can engage in self-deception to some extent, certain personality traits and cognitive biases are more common among those who consistently believe their own lies. Some notable characteristics include:

  • Narcissism: Individuals with narcissistic tendencies are more likely to engage in self-deception as a means of protecting their grandiose self-image.
  • Confirmation bias: People with confirmation bias tend to selectively seek and interpret information that confirms their pre-existing beliefs, reinforcing their self-deception.
  • Low self-awareness: Lack of introspection and self-reflection hinders individuals from recognizing their own self-deception.
  • Emotional reasoning: Relying heavily on emotions rather than rationality can lead individuals to believe their own lies, as emotions may distort their perception of reality.

Psychological Mechanisms Behind Self-Deception

Understanding the psychological mechanisms that enable individuals to believe their own lies is crucial in comprehending the complexity of self-deception. Here are some key mechanisms:

1. Cognitive Dissonance

Cognitive dissonance, a term coined by psychologist Leon Festinger, refers to the discomfort experienced when individuals hold conflicting beliefs or attitudes. Self-deception helps reduce cognitive dissonance by distorting or ignoring contradictory evidence.

2. Memory Distortion

Memory distortion plays a significant role in self-deception. Individuals tend to reconstruct memories to align with their self-perception and beliefs, leading them to genuinely believe their revised version of events.

3. Motivated Reasoning

Motivated reasoning is the process of selectively interpreting or evaluating information in a way that supports one’s pre-existing beliefs or desires. It involves biased thinking and can contribute to self-deception by reinforcing personal narratives.

4. Emotional Regulation

Emotions play a crucial role in self-deception. People often deceive themselves to regulate negative emotions such as guilt, shame, or fear. By distorting reality, they can protect themselves from emotional distress.

Examples of Self-Deception

Self-deception can manifest in various aspects of life, and examples can be found in personal relationships, politics, religion, and even within oneself. Here are a few notable examples:

1. Denial of Addiction

Individuals struggling with addiction often engage in self-deception by denying the severity of their problem, rationalizing their behavior, or blaming external factors. This self-deception allows them to continue their addictive behaviors without confronting the need for change.

2. Political Beliefs

Political ideologies can lead individuals to engage in self-deception by selectively interpreting information that aligns with their beliefs, while dismissing contradictory evidence. This can create echo chambers and reinforce polarized viewpoints.

3. Religious Beliefs

Religious faith can sometimes involve self-deception, as individuals may interpret ambiguous or contradictory religious texts to fit their personal beliefs. This enables them to maintain their faith while ignoring conflicting information.

Psychological Implications and Impact

The consequences of self-deception can be significant, both at an individual and societal level. Here are a few psychological implications and impacts:

1. Deterioration of Relationships

Self-deception can strain personal relationships, as individuals may deceive themselves and others about their true intentions, emotions, or actions. Trust and communication can suffer, leading to relationship breakdowns.

2. Reinforcement of Negative Behavior

Engaging in self-deception can reinforce negative behavior patterns. By distorting reality, individuals may avoid taking responsibility for their actions or seeking help, hindering personal growth and change.

3. Polarization and Conflict

Self-deception can contribute to polarization and conflict within societies. When individuals firmly believe their own lies, it becomes challenging to find common ground, fostering divisions and hindering cooperation.


Self-deception is a complex and intriguing phenomenon that involves individuals who not only deceive others but also convince themselves of their own lies. Motivations, characteristics, and psychological mechanisms all contribute to the ability to believe one’s own falsehoods. Understanding self-deception can shed light on human behavior and the intricate ways in which we perceive and interpret reality. By recognizing the presence of self-deception, we can strive for greater self-awareness and critical thinking, fostering healthier relationships and a more harmonious society.
