Over the last 20 years the web has changed the world, but what, if anything, has it done to us? Take part in a unique experiment to discover the impact the web is having on our brains, and discover which species of web animal you are. Take part in real science, Test takes 20 mins and you have to register with the bbc unless you already have a bbc id,Results will prove interesting. By taking part in the Web Behaviour Test, you’ll also be able to find out what sort of ‘web animal’ you are. You may well now be asking yourself: what on earth is a web animal? When we started designing this experiment, we talked about web behaviour in terms of ‘fox’ and ‘hedgehog’ people. Why? Strangely enough, because of a cryptic fragment of poetry by the ancient Greek writer Archilochus, which reads: “The fox knows many things, but the hedgehog knows one big thing.” For us, this was a good way of describing two broad groups of web users: sophisticated, social web users adept at skimming for information and multitasking (foxes) and less-sophisticated, non-social web users who focus on one task at a time and have a slower, more methodical approach to finding information (hedgehogs). But we quickly realised that there were more than two types of web users, so the number of species in our web ecology has now multiplied to eight. So which web animal are you?
