I’ve been a devoted, even fanatical reader of fiction my whole life, but sometimes I feel like I’m wasting time if I spend an evening immersed in Lee Child’s newest thriller, or re-reading The Great Gatsby. Shouldn’t I be plowing through my in-box? Or getting the hang of some new productivity app? Or catching up on my back issues of The Economist? That slight feeling of self-indulgence that haunts me when I’m reading fake stories about fake people is what made me so grateful to stumble on a piece in Scientific American Mind by cognitive psychologist Keith Oatley extolling the practical benefits to be derived particularly from consuming fiction.
