(Excerpt from Barking Up the Wrong Tree by Eric Barker)
Another study, titled “Tell Me What I Did Wrong,” showed that a shift takes place when people are on the path to expertise. Novices seek and need positive feedback because it keeps them working at something they’re not very good at. But there’s a tipping point. As someone becomes an expert they deliberately seek out negative feedback so they know how to keep improving now that their mistakes are fewer and subtler.
