It seems quite intuitive, but scientists have officially proved it – sharing common knowledge with someone makes you more likely to cooperate with him. This provides valuable insight into how altruism works, and how groups can cooperate towards a common goal.

It was a real breakthrough, since the work proved chimps are the first animals that we know of  that intentionally communicate through gestures inside their own society, apart from humans.
