Here’s a cheery one for our first episode of the year. Guess what happens when you give several sets of scientists the same dataset and ask them to answer the same question? Well, they all find the same results, right? Right!?

Sadly not. This “Many Analysts” problem has been analysed and debated in multiple different scientific fields and across several papers. We cover them in this episode. What does it tell us about the objectivity of science if different teams draw different conclusions from the exact same data?

The Science Fictions podcast is brought to you by Works in Progress magazine. Their excellent new article on how we’re living in “the golden age of vaccine development”, as discussed on the show, can be found (along with the rest of their articles on science, history, and technology), at worksinprogress.co. We’re very grateful that they support the podcast.
