The research team gave subjects with accelerometers on their wrists, head, and torso a high-difficulty puzzle while saying, 'It's an easy-to-solve puzzle.'

Furthermore, when the subjects lied to the lie by 'difficulty of lying', it was confirmed that the more difficult it was to lie, the stronger the tendency to imitate the movement.
