A Lexington sales director kept losing top performers. Exit interviews said he took credit for wins and blamed others for losses.
Negative personality traits are lasting patterns of thinking and behaving that harm your relationships, work, or well-being, such as dishonesty, arrogance, or chronic defensiveness.
The Lexington director was talented, but one recurring pattern was quietly costing him his best people.
Most negative traits are not fixed flaws but habits that developed for a reason and can be changed with awareness and practice.
The sections below explain what makes a trait negative, list 15 common examples with healthier alternatives, cover what research shows, and outline steps to change.
Naming a trait honestly is the first step to outgrowing it.

What Makes a Personality Trait Negative?
A trait becomes negative when it consistently hurts you or others, not when it simply differs from the norm.
Many negative traits are strengths taken too far: confidence can become arrogance, caution can become pessimism, and high standards can become perfectionism.
Context matters too, since bluntness may help in a crisis but wound in a conversation about grief.
Personality broadly is explained in how personality forms and changes.
Negative traits also differ from personality disorders, which are severe, long-lasting patterns diagnosed by professionals.
15 Negative Personality Traits
Interpersonal Traits
1. Arrogance: Acting superior and dismissing others’ views. The line between this and healthy self-belief is explored in arrogance versus real confidence.
2. Dishonesty: Lying, exaggerating, or hiding truths to avoid consequences or gain advantage.
3. Selfishness: Putting your own needs first regardless of how it affects others.
4. Manipulativeness: Using guilt, flattery, or deception to control what others do.
5. Jealousy: Resenting others’ success, attention, or relationships.
6. Rudeness: Interrupting, dismissing, or speaking harshly to people. Persistent harshness is covered in harsh, abrasive behavior.
Emotional Traits
7. Defensiveness: Treating feedback as an attack and arguing rather than listening.
8. Impatience: Frustration with delays and others’ pace, explored in why impatience happens.
9. Pessimism: Expecting the worst by default and dismissing hopeful possibilities.
10. Moodiness and Reactivity: Frequent, intense emotional swings that others must manage, explained in the roots of emotional reactivity.
11. Chronic Complaining: Dwelling on problems without seeking solutions.
Work and Responsibility Traits
12. Unreliability: Missing deadlines and breaking commitments.
13. Blaming Others: Refusing responsibility for mistakes, like the Lexington director. The healthier skill is described in owning your actions and reactions.
14. Perfectionism: Unrealistic standards that cause delays, stress, and harsh self-judgment.
15. Controlling Behavior: Micromanaging or needing control over other people’s choices.

The Dark Triad and the Dark Core
Psychologists Delroy Paulhus and Kevin Williams described the Dark Triad, three overlapping traits linked to harmful behavior: narcissism, Machiavellianism, and psychopathy.
Narcissism involves grandiosity and a need for admiration, Machiavellianism involves strategic manipulation, and psychopathy involves callousness and impulsivity.
Later research by Morten Moshagen, Benjamin Hilbig, and Ingo Zettler proposed a “dark factor” shared by many such traits.
They defined it as the tendency to put your own interests above others’, along with beliefs that justify doing so.
Dealing with someone high in narcissism is covered in living alongside a narcissist.
Where Negative Traits Come From
- Temperament: Inborn tendencies, such as high emotional sensitivity, can tilt toward certain patterns.
- Upbringing: Children copy what they see, and harsh or chaotic homes can teach defensiveness or manipulation.
- Protection: Many traits began as survival strategies, such as lying to avoid punishment or controlling to feel safe.
- Stress: Chronic stress and fatigue bring out people’s worst patterns.
- Reinforcement: Traits that get rewarded, such as arrogance in a competitive workplace, become stronger.
In Big Five terms, many negative traits reflect very low agreeableness or conscientiousness, or very high neuroticism, as explained in the Big Five trait model.
How Negative Traits Affect Your Life
Negative traits erode trust, damage relationships, and limit careers, since people avoid working with or confiding in those who make interactions painful.
They also harm the person who has them, leading to loneliness, conflict, and regret.
Can Negative Traits Change?
Yes. A 2017 review of 207 studies led by Brent Roberts found that personality traits changed meaningfully through intervention, especially emotional stability, over an average of 24 weeks.
Change is gradual, but consistent new behavior, feedback, and support can transform even long-standing patterns.
How to Change a Negative Trait
Get Honest Feedback
Ask trusted people which of your habits affect them most, since negative traits are easier to see from outside, as discussed in signs you lack self-awareness.
Pick One Trait
Choose the pattern causing the most harm and work on it alone first.
Find the Root
Ask what the trait protects you from, such as defensiveness shielding you from shame.
Identify Triggers
Notice the situations that bring the trait out, such as stress, fatigue, or certain people.
Practice the Opposite
Deliberately rehearse the healthier behavior, such as thanking someone for criticism instead of arguing.
Build New Habits
Repeat the new behavior daily until it becomes automatic, using practical habit-building strategies.
Repair Damage
Apologize to people your trait has hurt, and show change through actions.
Seek Professional Help
Therapy can help with deep-rooted patterns, especially those linked to trauma, anxiety, or personality disorders.
In my observation, people change negative traits fastest when they stop defending the trait and start getting curious about what it costs them.
Conclusion
The Lexington director began publicly crediting his team and owning his mistakes, and turnover dropped within a year.
Negative personality traits, from arrogance and dishonesty to defensiveness and controlling behavior, are patterns that harm relationships, work, and well-being.
Research shows personality traits can change, and honest feedback, practice, and support help people replace harmful patterns with healthier ones.
This week, ask one trusted person which of your habits they find hardest to deal with, and listen without defending yourself.
