Thought provoking

I'm going to list here links to two very interesting articles I read today. 

One about proposed systems to map and predict human group behaviour - and the implications of such research.

The other is about why children lie?  And when is a lie a lie and when is it actually socially acceptable and when do we determine this difference.

These are not cute or funny - but genuine thought-provoking pieces.
