As usual, a humorous articled with depth to it from Ming the Mechanic.
Ming reviews an article from the New York Times about an experiment with monkeys to see how an economy of giving weighs up in exchange rates.

Results = Monkeys on average are willing to give away 50% of the time
A monkey that gives away lots, gets back 30% of what they give
A monkey that gives away nothing, gets ignored, and insulted.

I reckon they’re pretty good stats to use next time I promote open courseware in a university…😉
