When Children Lie: What it means and how to teach about telling the truth
“Sawyer (5) cut the line for the slide at the playground. When I approached, to guide her to go back to her place, she started shouting at me that she didn’t cut. We got into this whole argument about whether or not she did something I witnessed with my own two eyes. She just dug in her heels deeper and deeper. It was insane. This kind of thing happens frequently—she’ll take her sister’s toy from her room and deny it. I don’t know what to do about this. Sometimes I worry I’m raising a sociopath!”
It’s important to see this behavior through the lens of development. Five-year-olds' moral reasoning is still heavily influenced by external consequences (e.g., avoiding punishment or pleasing adults) rather than an internal sense of morality. They lie to serve immediate needs, such as avoiding trouble or gaining attention. From a cognitive perspective, they don't fully grasp the broader social or relational impact of lying.
They are not sociopaths.
In this case, Sawyer knows she did something wrong and likely feels shame about it, a very difficult emotion she is trying to deflect via denial, as a way to cope with with this conflict.
