How to be not ignorant about the world

Recurring TED talker Hans Rosling returns with his son and Gapminder Foundation co-founder Ola Rosling and an update on their latest work: the Ignorance Project. They hope to shift people’s biased perception of world progress towards the statistics — and to surpass chimps in correctness.

The audience quiz and real-time results work perfectly. I’m guessing the audience answers on their keypads, Ola enters the results backstage, and then the audience sees the finished slide by the time Hans gets there.
