Abstract
A common perception is that the weaker science students are forced out of a competitive field, leaving the brightest stars to secure the desirable academic positions. But as Shambayati’s story shows — and as most mentors know — this is not the full picture: sometimes the scientists who move on are the ones with the most promise. Their motivations are diverse: some want more money, or more time with family; others are lured by opportunities elsewhere. To get a better sense of why talented scientists are leaving academia and how their training influences their lives, Nature contacted group leaders recognized for mentoring and asked: “Who was the one who got away?”
