Kinder children are more popular

The study revealed that kinder children were happier 
and found "greater acceptance in their peer groups"

Performing deliberate acts of kindness makes pre-teen children more popular with their peers, say scientists.

A team led by researchers at the University of California, Riverside, "assigned" children three acts of kindness each week for four weeks.

After the four weeks, children were happier and more liked by classmates.

The researchers say than encouraging such simple "positive acts" could help children to get along with classmates and even prevent instances of bullying.

The findings are published in the open access journal Plos One.
