Now scientists have uncovered an explanation for why telling a few porkies has the tendency to spiral out of control. The study suggests that telling small, insignificant lies desensitises the brain to dishonesty, meaning that lying gradually feels more comfortable over time.
Tali Sharot, a neuroscientist at University College London and senior author, said: “Whether it’s evading tax, infidelity, doping in sports, making up data in science or financial fraud, deceivers often recall how small acts of dishonesty snowballed over time and they suddenly found themselves committing quite large crimes.”
Sharot and colleagues suspected that this phenomenon was due to changes in the brain’s response to lying, rather than simply being a case of one lie necessitating another to maintain a story.
