Rosie is coming to the end of the R&D graduate scheme where she’s worked on a range of exciting technical projects. She studied BSc Physics to satisfy her curiosity in the universe before discovering a love of coding which led her to a masters in Computer Science. In her spare time she runs a technology blog called Microchicks with her colleague Becky.

First, Rosie explained the basics of Game Theory in the context of a social experiment game, based on a desert island:

You are put into pairs, and can choose to hunt or slack. Everyone has a reputation, what would mathematically be the best decision?

It turns out that mathematically it would always be best to slack, as you don’t waste energy hunting or lose your “kill” to other slackers. This strategy only works if some people don’t know, as someone needs to work to enable the “slackers” or everyone will go hungry!

Rosie explained how game theory is applicable in many areas of life, in our everyday interactions with others. People are more likely to team up with us if they perceive a benefit, and knowledge of game theory can help us all predict the behavioural patterns of our peers.
