(CBS) A new study throws more light on the power of peer pressure.
Researchers at the Max Planck Institutes watched the social behaviors of a group of 2 year olds.
They found that toddlers are more likely to copy an action if they see three of their peers do it first. That does not hold true if they see just one peer do it three times.
The study's conclusion is that even at the age of 2 the majority influences people.
