A scientific tightrope

The two most senior scientific advisors to the UK, Sir Patrick Vallance (Chief Scientific Advisor) and Professor Chris Whitty (Chief Medical Officer) have come into a lot of criticism recently for failing to say what they really believe regarding the Government’s response to the Covid-19 outbreak. As Civil Servants they are meant to be impartialContinue reading “A scientific tightrope”

Antimalarials for Covid-19

Another post concerning topics on Covid-19 aimed at the non-expert. Scientists are cautious by nature, some politicians and political journalists are not. While scientists say there’s no convincing evidence antimalarial drugs such as hydroxychloroquine have any effect on Covid-19, President Trump says, “there are some very strong, powerful signs of hydroxychloroquine as a Covid-19 therapy”.Continue reading “Antimalarials for Covid-19”

It’s not surprising there are so few accounts of the science becauseContinue reading “How do we know humans are responsible for climate change?”

The saying, “there are three kinds of lies: lies, damned lies, and statistics” is attributed to Mark Twain but may have originated from Benjamin Disraeli. It’s one of those phrases that has been misquoted more times than I can remember because in truth statistics is a branch of mathematics essential to understanding the world.
