Understanding why people lie has been a subject of psychological studies for years. New research sheds light on specific personality traits that are strongly associated with dishonesty. A study conducted at Texas Woman’s University’s Human Deception Lab examined 537 participants and found that certain "dark" personality traits significantly increase the likelihood of lying.
These traits include sadism, deceitfulness, and narcissism, with sadism having the strongest link to dishonesty.
Personality Traits Linked to Lying
Sadistic individuals often take satisfaction in seeing others struggle, and this trait appears to be a strong predictor of dishonesty. People who exhibit sadistic tendencies are more likely to lie, particularly when their falsehoods can cause harm or distress to others. Their dishonesty is often rooted in a desire for control or personal amusement rather than for personal gain.

2. Deceitfulness
As expected, individuals who are naturally deceitful lie more frequently. This personality trait is characterized by habitual manipulation, dishonesty, and a lack of regard for truth. The study found that people with this trait scored high across various types of lying, whether for self-benefit or to manipulate others for their advantage.
3. Narcissism
Narcissistic individuals tend to stretch the truth to protect their image or gain admiration. While the correlation between narcissism and lying was the weakest among the three traits, it was still present. Those with narcissistic tendencies are more inclined to exaggerate achievements, shift blame, or fabricate stories to maintain their self-image.
Types of Lies Associated With Dark Personality Traits
Lying isn’t always the same, and the research categorized different types of lies based on personality traits:
1. Vindictive Lies - Primarily told by individuals with sadistic or vindictive tendencies, these lies are meant to harm others.
2. Self-Serving Lies - More commonly associated with narcissism, these lies help maintain self-image or gain admiration.
3. General Dishonesty - People with deceitful personalities are more likely to lie in all contexts, from minor falsehoods to major fabrications.
4. Altruistic Lies - Interestingly, the study found no strong link between dark personality traits and altruistic lying (lies told to protect others or spare feelings).
Why Understanding These Traits Matters

Recognizing these personality traits can help in personal and professional relationships. Whether dealing with colleagues, friends, or leaders, being aware of the likelihood of dishonesty based on personality can help in assessing credibility.
Psychology professor Christian Hart, who oversaw the study, emphasized that identifying these traits can serve as a useful tool in determining honesty. "Understanding what drives manipulation and dishonesty allows us to be more cautious in who we trust," he noted.
How to Spot a Habitual Liar
While personality traits provide insight, there are additional behavioral cues that indicate dishonesty. Some common signs include:
1. Inconsistencies in Stories- Frequent contradictions or changing details in a person's statements.
2. Defensiveness - Overreacting when questioned about details.
3. Lack of Eye Contact - Though not always a definitive sign, avoiding direct eye contact can be a red flag in some cases.
4. Unnecessary Justifications - Providing excessive explanations for something simple.
Lying is a complex behavior influenced by various psychological factors. While not everyone who lies fits into these personality categories, understanding these traits can provide valuable insights into human behavior.
Recognizing the patterns of dishonesty in everyday interactions can help in making informed decisions about whom to trust.
