Little liars: babies younger than one practise deceit, study suggests

AI Summary

medium article 3 min

A new study from the University of Bristol suggests that babies begin practicing rudimentary forms of deception as early as 10 months old. Researchers interviewed over 750 parents in the UK, US, Australia, and Canada about their children's deceptive behaviors. The study found that approximately 25% of 10-month-olds exhibited behaviors like pretending not to hear or hiding forbidden foods. By age three, children demonstrated more frequent and creative deception. The research suggests that deceptive behavior develops gradually from a young age, possibly stemming from a desire to get away with things or obtain extra treats. This challenges previous assumptions that deception requires advanced language skills and understanding.
