Challenging Scientific Paradigms

John Mattick is Professor of RNA Biology at the University of New South Wales in Sydney, Australia. For decades, he has been on a mission to show that the large portions of the human genome that many scientists consider useless "junk" instead have important regulatory functions. In this episode, he tells us that his creative process involves always seeing things from different perspectives – something he learned as a teenager listening to the debates of his mother and her sisters. He reveals how publishing a manifesto can supercharge your research. We discuss how science lurches from paradigm to paradigm, and how the current best guess, if untestable at the time, can become accepted wisdom. And he tells us that he advises his graduate students that it's very hard to be creative when you're still in the fog of ignorance, but that they should always look for the things that don't make sense to them - sometimes that's a clue to something worth chasing.
