We live in a social world - one philosopher once called humanity “the ape that talks”, and we’re constantly talking, discussing, arguing, and sharing ideas and opinions. In general, I think this is great - communication has the capacity to widen our scope, to let us understand each other and the world. However, like every scientific and technical invention, modern communications (and especially social media and the internet) have their dark side. Beyond the cosy family chat, or judicious and informed news website, There be Dragons. I hope to look at data issues in veterinary practice in a later blog, but today I plan to do battle with just one of those dragons - Rumour. Specifically, the wide range of drug safety rumours that do the rounds on social media.
