So-called "social experiments" all the rage these days. Whether or not they are actual scientific experiments is a different matter, but they do attempt to provide insight into basic questions about ourselves and how people react in certain situations.
One of the most recent experiments to gain attention on Youtube is by a Norwegian group called SOS MAYDAY. According to their Youtube page, the experiment is meant to raise awareness for the plight of children in the winter campaign in the Syrian Civil War.
From their Youtube page:
What would you do if you saw a freezing child?
We set up a hidden camera and placed Johannes at a bus stop, in Oslo, Norway. This is what happened.
The film is made to raise awareness of the situation for children in Syria, and to raise funds to SOS Children's Villages is their winter-campaign. Children in Syria are freezing and you can help by dontating. For more information: www.sos-barnebyer.no/Mayday/Syria
