Trust is one of the foundational pillars of any relationship, whether personal or professional. When someone repeatedly shows signs of deception, manipulation, or inconsistency, it becomes clear they may not be as trustworthy as they seem. Let’s dive into 15 deceitful traits that are often telltale signs of people you might want to keep at arm’s length.
1. They Lie Without Missing A Beat
Compulsive lying is a hallmark trait of untrustworthy people. Whether it’s about small, seemingly inconsequential matters or more impactful issues, they lie to suit their narrative. These lies often appear casual, making it harder to detect their dishonesty initially. Over time, these consistent falsehoods erode trust and create doubt about everything they say. It’s a clear red flag when someone shows no hesitation in distorting the truth.
According to Psychology Today, lying is often a learned behavior rooted in a desire to manipulate outcomes or avoid accountability. People who habitually lie lack transparency and usually leave others questioning their motives. This deceitful behavior can have ripple effects, damaging both personal and professional relationships. The inability to be truthful is not just a bad habit but a breach of trust often has far-reaching consequences.
2. They Never Admit They’re Wrong
Untrustworthy people rarely admit when they’ve made a mistake. Instead of owning up to their actions, they deflect blame onto others or invent excuses. They may play the victim, painting themselves as misunderstood or unfairly targeted, to evade responsibility. This behavior shows a lack of integrity and creates an environment of mistrust and frustration for those around them. Accountability is a key component of trust; its absence often speaks volumes about someone’s character.
People who avoid accountability often struggle with personal growth because they refuse to acknowledge their flaws. According to Forbes, accountability creates stronger relationships by building trust and mutual respect. Those who consistently avoid it show they care more about self-preservation than resolving issues or improving. Their behavior creates unnecessary tension and leaves others feeling unsupported. This repeated pattern can make them difficult to rely on in any situation.
3. They Overpromise and Underdeliver
Promises mean nothing to untrustworthy people because they rarely follow through. They often make grand commitments to gain favor or appear reliable but fail to meet expectations. This behavior creates frustration and disappointment for those who depend on them. Their inconsistency damages their credibility over time, making others less likely to trust their words or intentions. When someone consistently overpromises and underdelivers, it’s often a sign of manipulation or carelessness.
People who behave this way might justify their actions by blaming circumstances or others. According to Mind Tools, reliability is built when people consistently deliver on their promises, no matter how small. Breaking commitments shows a lack of respect for others’ time and needs, highlighting their deceitful tendencies. Overpromising isn’t just a bad habit—it’s a manipulation tactic that undermines trust. When someone repeatedly lets you down, their actions speak louder than their words.
4. They’re Always Engaging In and Spreading Gossip
Trustworthy people protect the reputations of others, while untrustworthy people relish spreading gossip. These individuals often share personal or confidential information about others for entertainment or social leverage. This behavior is harmful and a sign that they may do the same with your secrets. Gossiping shows a lack of integrity and respect, making it clear they cannot be trusted with sensitive information. If they gossip about others, they’re likely gossiping about you, too.
According to Psychology Today, gossiping can be a tool for social bonding but often leads to fractured relationships and diminished trust. People who engage in gossip undermine group harmony and create unnecessary drama. Their constant focus on others’ flaws or missteps reveals a lack of emotional maturity and a tendency toward deceit. By prioritizing gossip, they demonstrate they value attention over trustworthiness. This behavior is a clear indicator of their unreliability.
5. They’re Chronically Late
Being late occasionally is normal, but habitual tardiness signals deeper issues, such as a lack of consideration or organization. Untrustworthy people often fail to respect others’ time, leaving them waiting or scrambling to adjust plans. Chronic lateness might also be used as a power play, subtly asserting control over situations. While they may offer excuses, the repeated behavior demonstrates a pattern of disrespect. It shows they prioritize their needs over others’ schedules.
Punctuality is an often-overlooked sign of trustworthiness. Time Magazine says being consistently late can erode trust and damage relationships. It conveys that they do not value the commitments or time of those around them. Being unreliable in this way creates tension and frustration, making it hard to count on them. When someone repeatedly fails to meet deadlines or arrive on time, it’s a sign they may not respect their commitments.
6. They Exaggerate or Embellish Stories

Untrustworthy individuals often embellish their stories to make themselves appear more impressive or sympathetic. They inflate details, twist facts, or outright fabricate events to gain attention or manipulate perceptions. While it may seem harmless at first, this habit reveals a deeper pattern of dishonesty. Over time, their exaggerations make it hard to discern truth from fiction, leading to mistrust. Their constant need to enhance reality often stems from insecurity or a desire to control the narrative.
Exaggeration can be a subtle form of deceit that erodes credibility. People who frequently exaggerate struggle to build authentic relationships because their words lack reliability. Their tendency to twist the truth makes trusting their intentions or actions challenging. This behavior creates a shaky foundation for any relationship, personal or professional. Trust requires authenticity, and chronic exaggeration undermines it at every turn.
7. They Constantly Blame Shift
Blame-shifting is a classic trait of those who can’t be trusted. Instead of taking responsibility for their actions, they deflect fault onto others or external circumstances. This tactic protects their ego and keeps others off balance, questioning their role in conflicts. Their inability to accept accountability often leads to unresolved issues and damaged relationships. Blame-shifting is not just frustrating—it’s a clear sign of emotional immaturity and manipulation.
According to Inc., avoiding accountability is a common tactic of those with manipulative tendencies. People who shift blame refuse to acknowledge their role in problems, making it impossible to resolve conflicts constructively. This behavior erodes trust over time, as their actions consistently show a lack of integrity. Relationships with such individuals often feel one-sided and exhausting. Trustworthy people own their mistakes and work toward solutions; untrustworthy people avoid both.
8. They’re Overly Secretive

While everyone values privacy, untrustworthy people take secrecy to an extreme. They avoid sharing basic information and often act suspiciously when asked direct questions. This excessive secrecy can leave others feeling excluded or mistrustful of their intentions. Their guarded nature usually masks hidden agendas or questionable actions. When someone is overly secretive, it’s natural to wonder what they’re hiding.
Excessive secrecy can create barriers in relationships and lead to feelings of distrust. Trust is built on openness, and when someone withholds too much, it creates emotional distance. While privacy is important, a complete lack of transparency can signal deceit. Healthy relationships thrive on balance, where both parties feel safe to share. Chronic secrecy disrupts this balance and raises red flags.
9. They’re All Over The Place
Untrustworthy people often show inconsistencies in their words, actions, and behavior. They might make promises one day and break them the next or say one thing and do another. This unpredictability creates confusion and makes it difficult to rely on them. Over time, their inconsistent behavior erodes trust, leaving others frustrated or disillusioned. Consistency is a cornerstone of dependability, and its absence is a major red flag.
Unreliable people fail to build this foundation, making their actions unpredictable and their motives questionable. Their erratic behavior can strain relationships as others struggle to understand or depend on them. Trustworthy people align their actions with their words, creating a sense of security. Inconsistency, by contrast, is a clear indicator of unreliability.
10. They Manipulate Situations to Their Advantage
Manipulation is a key trait of untrustworthy individuals. They twist circumstances or exploit others’ emotions to get what they want. Whether through guilt-tripping, playing the victim, or using charm as a weapon, their actions are self-serving. This behavior creates an environment of suspicion, as their intentions rarely align with their words. People around them often feel used or deceived once their true motives become clear.
Manipulation undermines trust and damages relationships over time. Those who manipulate prioritize their own needs above all else, often at the expense of others. Their actions reveal a lack of empathy and a willingness to deceive for personal gain. Building trust with someone manipulating is nearly impossible, as their motives are always in question. Recognizing this behavior early can help protect your emotional well-being.
11. They Break Promises All The Time
Breaking promises might happen occasionally, but untrustworthy people make it a habit. They overcommit or make empty assurances, knowing they won’t follow through. This behavior creates a cycle of disappointment and frustration for those who depend on them. Each broken promise chips away at their credibility, making it harder to trust them in the future. Reliability is key to trust, and consistently breaking promises destroys it.
People who habitually break promises often lack accountability or awareness of the impact of their actions. Keeping promises is essential for building trust and maintaining healthy relationships. Failing to do so signals a lack of respect for others’ time and needs. Trustworthy individuals honor their commitments, no matter how small. When someone consistently fails to do so, it’s a clear sign of their unreliability.
12. They Resort To Gaslighting
Gaslighting is a form of manipulation that makes others question their reality. Untrustworthy people use this tactic to shift blame, avoid accountability, or control situations. By denying facts or distorting the truth, they create confusion and self-doubt in others. This behavior is not only deceitful but also emotionally damaging. Gaslighting erodes trust by undermining others’ confidence in their perceptions.
As explained by Healthline, gaslighting is a manipulative tactic designed to destabilize and control others. People who engage in this behavior are often deeply untrustworthy, as their goal is to create dependence and confusion. Recognizing gaslighting early can help you protect your mental health and set boundaries. Trust requires honesty and clarity, which are absent in a relationship with a gaslighter. Their actions create a toxic dynamic that’s difficult to navigate.
13. They Prioritize Themselves First
Untrustworthy individuals often exhibit selfish behavior, prioritizing their needs at the expense of others. They rarely consider how their actions impact those around them, focusing solely on personal gain. This self-centeredness creates a one-sided relationship dynamic where others feel undervalued and unappreciated. Their inability to empathize makes it clear they can’t be relied upon for support. On the other hand, trustworthy people balance their needs with those of others, fostering mutual respect.
Selfish behavior often masks deeper insecurities or a lack of emotional maturity ,and selfish people struggle to form meaningful connections because their actions alienate others. Their lack of concern for others’ well-being makes them unreliable in times of need. Trust requires a willingness to put others first occasionally, something selfish individuals rarely do. This lack of balance is a clear indicator of their untrustworthiness.
14. They Rarely Show Empathy
A lack of empathy is a defining trait of those who can’t be trusted. They struggle to understand or care about others’ feelings, making them indifferent to the consequences of their actions. This emotional disconnect often leads to behavior that prioritizes self-interest over mutual benefit. Without empathy, building the trust required for meaningful relationships is nearly impossible. People around them often feel unseen and unsupported, eroding any sense of connection.
Empathy is the foundation of trust and emotional intimacy. According to the Greater Good Science Center, empathy allows us to connect deeply with others and fosters stronger relationships. By lacking this key trait, untrustworthy people often fail to create lasting bonds. Their inability to empathize highlights their emotional unavailability and self-focus. Without empathy, trust has no room to grow, making relationships shallow and transactional.
15. They’re Blatantly Opportunistic
Untrustworthy individuals often take advantage of situations to serve their interests, regardless of their impact on others. They might exploit friendships, bend rules, or manipulate circumstances to gain an edge. This opportunistic behavior reveals a lack of integrity and a willingness to deceive for personal gain. While they may initially seem charming or resourceful, their actions eventually expose their true motives. Trustworthy people prioritize fairness and integrity, while opportunists prioritize themselves.
Opportunistic behavior undermines trust and damages relationships. People who act this way rarely consider the long-term consequences of their actions, focusing only on immediate benefits. This short-sightedness often leads to fractured relationships and a reputation for dishonesty. Recognizing opportunistic tendencies early can help you protect yourself from potential manipulation. Genuine trust requires a foundation of fairness and mutual respect, which are absent in an opportunist’s actions.
