This month we discuss Why science is sexist by Nicola Gaston. That science is sexist isn't a question Nicola Gaston entertains – it is. Rather, she wants to know why a field that prides itself in being rational should behave so illogically.We discuss the research she presents on unconscious bias, in both men and women. And we talk about whose responsibility it is to address the problems of sexism, and what indeed they should do to address them. Hear an extract from the book, an interview with Nicola Gaston, and the views of the Chemistry World team in this month's podcast. You can read our review of Why science is sexist here, and find all our book reviews here. We want to include you, the Chemistry World reader, in the conversation so join us next month when we’ll be discussing Scientific Paper Writing - A Survival Guide by Bodil Host. Tweet your thoughts to @ChemistryWorld, or use the hashtag #BookClubCW and we’ll endeavour to include your opinions (or questions) on the podcast.
