Why Do Teenagers Lie? Tips for Parents

lying teenager

In a study performed by Nancy Darling, a specialist in young adults behavior and deception, she revealed that nearly 96 percent of teenagers are untruthful to their parents. Another study demonstrated that within the past year, 82 percent of high school and college students confessed to deceiving their parents. From either of these situations, we can understand that teens lie more than many grownups think.

So, what causes teens to tell lies? Continue reading and learn the reason behind your teen’s dishonesty and how you can spot them. In some uncommon cases, compulsive lying can start teens on a downward trajectory leading to the need for teen residential treatment. This is because lying can be just a symptom of a larger mental health issue.

What Causes Teenagers to Tell Lies?

Teenagers lie for many reasons, but the big three are: avoiding punishment, impressing peers, and low self-esteem.

Avoiding Punishment. When teens know they’ve screwed up, lying to get out of trouble seems like the easy way out. Whether they’re lying about skipping class or breaking curfew, teens will spin a web of deceit to avoid facing consequences.

Impress Peers. Teens also lie to seem cool to their friends. They may lie about things they have or haven’t done to gain status and fit in. These lies are hard to spot since teens work hard to keep up appearances.

Low-Self Esteem. Some teens lie compulsively due to low self-esteem. They create an imaginary life they feel is more exciting or impressive than their own. These lies are often easy to catch, but addressing the underlying self-esteem issues is challenging.

It’s important for parents and guardians to approach teen lying with empathy and open communication. Understanding the reasons behind the lies can help foster a more trusting and supportive relationship.

What are the Things that Teenagers Often Lie About?

Teens can lie about a wide range of subjects, often stemming from their desire for independence, social pressures, and the challenges of growing up.  It’s important to understand  not only the underlying reasons prompting teens to lie but also what they are lying about, which could include:

Social Activities

Teens might lie about where they’re going, who they’re hanging out with, or what they’re doing to gain more freedom and avoid parental restrictions.


Some teens might downplay their workload, grades, or assignments to reduce pressure or avoid getting in trouble for not completing their tasks.

Substance Use

If experimenting with substances, teens might lie about their involvement to avoid parental or authority figures’ disapproval or punishment. At Paradigm, we offer teen substance abuse treatment for those needing to recover from mild to severe addiction issues.

Peer Interactions

Adolescents might exaggerate stories about friendships, relationships, or social events to gain attention or fit in with their peers.

Technology and Screen Time

Teens might lie about their online activities, the content they’re consuming, your teen’s addiction to social media, or other screen-related activities to evade restrictions or judgments.

Personal Interests

To conform to peer norms or parental expectations, teens might lie about their interests, hobbies, or activities they’re engaged in.

Feelings and Emotions

Some teens might hide their true emotions to protect themselves from vulnerability or to avoid burdening others with their problems.

Dating and Relationships

Teens might lie about their romantic relationships, experiences, or interactions to keep certain aspects of their personal lives private.

Family Matters

Teens might lie about family situations, conflicts, or dynamics to avoid judgment from peers or to present a more desirable image.

Future Plans

To reduce pressure from parents or teachers, teens might lie about their future goals, aspirations, or college plans.

How to Spot When Your Teen is Lying?

Spotting when a teenager is lying can be challenging, but there are certain signs and cues that parents and guardians can watch for. Here are some potential signs to look out for:

  • Inconsistencies in Details: If your teen’s story changes or if they provide inconsistent details when recounting an event, it could be a red flag that they are not telling the truth.
  • Avoiding Eye Contact: A sudden shift in eye contact or a notable avoidance of eye contact during the conversation might suggest that they are uncomfortable or possibly concealing something.
  • Unusual Body Language:  Physical cues like fidgeting, nervous gestures, or excessively touching their face while talking might indicate that your teen is anxious about the conversation.
  • Defensiveness: If your teen becomes overly defensive, angry, or agitated when questioned, it might be an attempt to divert attention from the truth or avoid further scrutiny.
  • Overexplaining: Providing an excessive number of unnecessary details or elaborating on certain aspects of a story might be an attempt to divert attention from the truth.
  • Inconsistency with Previous Behavior: If their actions don’t align with their usual behavior or values, it might be worth exploring the reasons behind the inconsistency.
  • Changes in Vocal Pitch: A sudden change in their vocal tone, such as speaking higher or lower than usual, might indicate heightened stress or nervousness.
  • Unusual Emotional Reactions: Expressing emotions that seem disproportionate to the situation, such as laughing during a serious conversation, could be a sign of discomfort or nervousness.

Parents often have an intuitive sense when something is off. If your instincts tell you that your teen might not be telling the truth, it’s worth addressing the situation with sensitivity.

What are the Types of Lies Teenagers Tell?

Teenagers lie for all sorts of reasons, and as a parent, it’s important to understand why so you can better address it. The lies typically fall into a few categories:

White lies are meant to be harmless, like lying about brushing their teeth or doing homework. Teens tell these to avoid getting into trouble or disappointing you.

Exaggeration is stretching the truth to seem more impressive. Your teen may brag about accomplishments or experiences to seem cooler to friends. This is usually harmless but can damage trust over time.

Lying by omission leaves out important information. Your teen may not tell you about a bad grade, a party they went to, or a new relationship. Omission is meant to avoid punishment or judgment.

While some lying is normal as teens start to gain more independence, frequent lying can be a sign of a bigger issue and damage your trust. This is when teens are called to become compulsive liars, where they lie so frequently that they have trouble stopping. To learn more and understand better, just continue reading to delve further into this topic.

Is My Teen a Compulsive Liar?

Compulsive lying means your teen lies repeatedly for no reason. Some signs your teen may be a compulsive liar:

  • Their stories often change or don’t add up.
  • They lie about small, unimportant things.
  • They lie even when the truth would have no consequences
  • They lie to get attention or make their lives seem more exciting or dramatic.

If your teen shows these signs, it’s a good idea to speak with a counselor. Compulsive lying can be a symptom of other issues like low self-esteem, anxiety, or impulse control problems that require professional support.

To help curb compulsive lying:

  • Express your concern for their well-being and your desire to strengthen your relationship.
  • Establish well-defined guidelines and rational repercussions for instances where these guidelines are violated. Be consistent in following through.
  • Praise your teen when they tell the truth, especially about hard things. Provide positive reinforcement to help shift the behavior.
  • Monitor them and verify stories when possible. Look for inconsistencies in their stories.
  • Spend quality one-on-one time together engaged in open conversation. Make it a habit and a safe space for them to share without judgment.
  • Consider counseling or therapy. Speaking to a professional counselor in anxiety treatment for teens can help uncover the underlying causes of compulsive lying and give you strategies for overcoming them.

The teen years are challenging, but maintaining an open and honest relationship with your teen is so important. With patience, consistency, and the right support, compulsive lying can be overcome and trust rebuilt.

Why Honesty and Communication Are Keys for Parents and Teens?

Rebuilding trust is essential for a healthy parent-teen relationship. As a parent, finding out your teen has lied can be hurtful and damaging to your bond of trust. However, it’s important to understand why teens may lie and take steps to improve communication.

Teens often lie to avoid punishment, spare feelings, or gain more independence as they navigate the challenges of adolescence. The lies tend to center around risky behaviors, poor grades, relationships, or broken rules. While lying is never acceptable, try to stay calm and address the underlying issues. If lying has become a habit or includes elaborate, made-up stories, speak to a counselor. They can help determine if therapy or counseling would benefit your teen.

To rebuild trust,

  • Focus on listening without judgment.
  • Encourage your teen to open up. Express how their lying made you feel
  • Establish clear rules and reasonable consequences when those rules are broken.
  • Be transparent in your own communication and lead by example.
  • Monitor for repeat lying, but also express your belief in them and offer second chances.
  • Maintain an open heart, open lines of communication, and an open-door policy. Make your home and relationship a safe space where truth and trust can blossom again.

With time and effort, you can restore honesty and closeness with your teen. But this requires patience, understanding, and recognizing that they are learning and growing into responsible young adults.
