Malcolm Gladwell's latest book, Outliers, is the inspiration for a blog post at In the Pipeline. Derek Lowe wonders if Gladwell's "10,000 hour rule," the idea that many people who are extremely good at a given task have spent at least that long perfecting their skills, can be applied to science, and drug discovery in particular. When it comes to science, says Lowe, referring to a review of the book, practicing an art is different from pipetting mindlessly for four years because, well, that's part of logging hours in the lab, too. Which category does drug design fit into?
