The first line of Jonah Lehrer’s Wikipedia page says nothing of his best-selling books, his Rhodes scholarship, his myriad contributions to Wired and The New Yorker or the fact that he has spent most of his adult years as a pop science wunderkind. What it mentions, first and foremost, is Lehrer’s plagiarism scandal, which precipitated his fall from grace four years ago this summer. Lehrer himself acknowledges this fact early on in the author’s note to his latest book, A Book About Love: “I broke the most basic rules of my profession. I am ashamed of what I’ve done. I will regret it for the rest of my life.”

Art restoration experts often disagree over how much to intervene. A compulsive tinkerer can just as easily botch a precious masterpiece as renew it, and overzealous cleaning can leave a work looking whitewashed. But whether you favor a conservative or liberal approach to restoration, pretty much everyone can concur that breaking off the burial beard of a 3,300-year-old sarcophagus and then sticking it back on with cheap glue is, generally speaking, not a good practice. Especially when that beard belongs to King Tut.
