Are you confused why children lie? Do you get that feeling your child too is dishonest sometimes? And anyway, should this behavior concern you as a parent?

Well, such are questions that rattle the mind of every parent, especially one coping with a kid who has just gone past the third birthday, and is a compulsive liar!

Here’s the thing, children learn to tell soft lies at around 3 years, and will fine-tune the skill by the time they are 7, when they tell carefully planned lies. This behavior will persist through the teen years, up until they are adults.

Lying becomes a real habit during adulthood, and this explains why we lie as parents. We lie a lot, even to our own kids, and it’s ironic we expect them to be any different!

I guess this is food for thought!

Let’s set one record straight; Lying is bad most of the time, but maybe not always. Sometimes lying is ‘good’ when told for good reasons, say prosocial lies. However, lying is bad if told for personal gain, say antisocial lies.

The good lies are called white lies and the bad ones, black lies. Interesting choice of words though.

Now, back to the main question, why do kids lie? But before that, what is lying anyway?

In brief, lying defines a situation where one person says deliberate falsehood with the intention of deceiving another.

Children lie when they say falsehood to peers, and when they tell parents falsehood on what they have done, or not.

Below are common reasons why children lie:

1. Children lie because parents want them to!

Well, come to think of it: when we accuse children of falsifying information, we always assume they are lying. Most of the time, this is not always the case. 

We actually don’t listen to them when they try to explain themselves, simply because we have made up our minds. We pressurize them to accept what they have not done.

We promise not to spank them if they tell the truth we want to hear. They more than likely will take the cue, accept what they have not done, and escape the punishment.

It is also interesting when we offer incentives in order to get the truth out of them. I am sure you have heard siblings argue over who actually did what when incentives are put on the table.

It is only then that we find out who actually lied, and how wrong we were to judge one child against the other!

How about you convincing them to like a clip from a 20th-century movie because it still makes your ribs crack? Seriously, your 21st-century kid does not see the fun in a 20th-century movie.

Irrespective of this, you cajole them up until they lie that they do!

Well, the list is endless, and the little fellows will continue dancing to your tunes to please you. It is no wonder they become liars early on in life.

2. Children lie because parents & others lie!

Yes, this begins when we ask children to tell a visitor at the door we are not at home when actually we are. We also ask them to tell the neighbor the gift she sent for Mary’s birthday was amazing when actually everyone at home thought it was pathetic.

How about your child coming home with an awful drawing, and you have to laud him with praises because you want to keep his spirit up?

Ok, let’s not forget the lies about Santa coming home on Christmas eve to drop a present.

Then there is the Tooth fairy tale from multiple traditions which tells of a mouse visiting with a gift every time the child extracts a primary tooth!

Besides parents, neighbors, cartoons, movies, TVs, and most people around children perpetrate lies all the time.

It happens all the time and it is a question of parents and everyone else telling lies without evaluating the consequences. We probably do it because we want to offer encouragement, and preserve the child’s sense of security.

Children embrace these sweet lies but over time discover they are actually lies. Soon enough, they too begin using them.

3. Children lie to get what they want

Children are hungry for attention, crave their favorite cookies and toys, and want to be near their beloved nanny and uncle.

They will lie in order to have an hour or two on the game console, laptop, or smartphone. They want everything that makes their lives worth living because they live in a material world.

At the end of the day, anything that justifies their needs – lies included, will work just fine.

They never understand that a lie told today will come to haunt them tomorrow or next week because they do not have the perception that facts are fixed.

In fact, the distinction between fantasy and fact is based on when a lie gets them what they want. As long as a lie helps them get their favorite cookie, then to hell with the truth.

Children will also lie to

Beware though of the negatives that come with some of the lies such as addiction to technology devices, apathy, and bullying.

4. Children will lie for cognitive development

Children also lie because they are discovering themselves and new things in life. Throughout the 3rd to the 7th year, they are at work trying to develop social and cognitive skills, and as ludicrous as it sounds, they use lying as a yardstick to measure their progress.

Starting early on, they are learning to develop a knowledge base, understand beliefs, and find out what is socially right or wrong.

According to Michael Lewis, professor of pediatrics and psychiatry at Rutgers Robert Wood Johnson Medical School,

Lying is a basic process that gets us into imagination and into play and into creativity

Children will lie to discover and try out many new things. For example, they will lie to

  • build confidence
  • excel in class
  • discover new ideas
  • find out how smart they are

By lying they learn how it feels to lie and how people respond to lies!  

5. Kids lie to evade focus

If you have been in a situation where your child is suffering from depression, anxiety, and ill health, you will agree with me your child will lie every now and then to make you feel better.

They are uncomfortable and feel under unnecessary pressure when they have to explain how they feel every now and then. Sometimes, children just want to be left alone. This is the reason not to put your children under pressure.

Have your child speak the truth

We will probably agree that lying is not the best of traits we want our children to develop, especially when it interferes with productivity and family values.

Here are some of the things parents and children can do:

  • Parents should cut down on their own lies
  • Children should be made aware that lying is not okay
  • Parents and children should mend the lies by fixing them mentally and physically
  • The Bible and other religious books condemn lying as evil
  • The consequences of lying in real life are serious
