🤥 The Ripple Effect: How Parental Lies Shape Children’s Honesty

11/14/2025

Why “Harmless” White Lies and Instrumental Deception May Backfire

Lying is often seen as a part of parenting. Parents may employ deception to guide behavior, protect emotions, or encourage compliance. From gentle exaggerations to promises that may not be kept, these strategies are widespread across cultures.

But a recent study from Nanyang Technological University (NTU Singapore) reveals a nuanced truth: even seemingly harmless parental lies can influence children’s own honesty, sometimes in unexpected ways.



🔍 The Study at a Glance

The NTU investigation involved 564 parent-child pairs in Singapore, focusing on children aged 11–12, an age when cognitive understanding of deceit becomes more sophisticated. The research explored two types of parental deception:

  1. Instrumental Lies – lies meant to influence behavior, such as: “If you don’t clean your room, I’ll call the police.” “Finish your homework and I’ll take you to Disneyland.”
  2. White Lies – lies aimed at fostering positive feelings, e.g.: Praising a child’s drawing as “excellent” even if it was average. Offering reassurance about performance to avoid discouragement.

Parents reported the frequency of these lies, while children indicated both their belief in the lies and their own honesty towards their parents.



🧠 Key Findings: Lies Breed Lies

The study, published in the Journal of Experimental Child Psychology, highlights several critical insights:

1. Instrumental Lies Increase Child Deception Across the Board

Children exposed to behavior-shaping lies were more likely to deceive their parents, regardless of whether they realized they were being misled.

  • Researchers suggest that children may see deceit as an effective problem-solving tool.
  • Instrumental lies can also create negative emotional tension, straining trust and increasing the likelihood of dishonesty.

2. White Lies Have a Conditional Impact

Children were more likely to lie when they recognized they were being deceived for emotional comfort.

  • Awareness seems to shape whether children adopt deceit as acceptable behavior.
  • This highlights the subtle cognitive processes through which children interpret parental intentions and moral boundaries.


📊 How the Research Was Conducted

The NTU team, led by Associate Professor Setoh Peipei of the Early Cognition Lab, used questionnaires to assess both parental lying and children’s dishonesty:

  • Parents and children rated the prevalence of instrumental and white lies on a 1–5 scale.
  • Children reported how often they were dishonest toward parents, also on a 1–5 scale.
  • Researchers analyzed correlations, factoring in children’s awareness and belief in parental deception.

This approach allowed the team to distinguish between the effects of intentional manipulation and emotional white lies.



💡 Why This Matters for Parents

Parents are often role models for moral behavior. NTU’s findings suggest that even well-intentioned deception can unintentionally teach children to lie:

  • Instrumental lies may normalize deceit as a problem-solving strategy.
  • White lies, when recognized, can lead children to adopt selective dishonesty, thinking deception is acceptable under certain conditions.
  • Both forms of parental deception can subtly influence social and emotional development, shaping children’s understanding of trust, honesty, and relationships.
“Our research demonstrates that parental dishonesty can inadvertently shape children’s attitudes towards lying,” says Assoc Prof Setoh. “Even lies perceived as harmless have consequences, especially when children are cognitively aware of them.”


🛠️ Practical Takeaways for Parents

  1. Prioritize transparency where possible ✅ Children internalize honesty best when parents model it consistently.
  2. Use explanations instead of deception 💬 Rather than saying, “I’ll call the police if you don’t behave,” explain the consequences of actions calmly.
  3. Be mindful of white lies 🌟 Praise effort over outcome. Focus on encouragement without stretching the truth.
  4. Observe children’s responses 👀 Awareness and interpretation of lies can influence whether they adopt dishonest behavior themselves.


🌱 Future Directions

NTU researchers propose longitudinal studies to trace how children’s exposure to different types of parental deception affects honesty over time.

  • Such studies could reveal how early experiences shape moral reasoning, socialization, and trust in adults.

Understanding the ripple effect of parental lies is vital: it informs not only parenting strategies but also broader insights into child socio-emotional development.



🔑 Key Takeaways

  • Parental deception isn’t just “harmless white lies” or temporary tools—it can shape children’s honesty patterns.
  • Instrumental lies often lead to more frequent child deceit.
  • White lies can also influence dishonesty if children recognize the deception.
  • Parents are role models: fostering trust and honesty starts with transparency and thoughtful communication.
