Almost a year after journalist Jonah Lehrer admitted to ethical lapses in his writings and resigned from The New Yorker, leading Houghton Mifflin Harcourt to pull his best-selling book “Imagine” off shelves, Houghton said Friday that it is pulling a second book by Lehrer. The Daily Beast website reported that Houghton senior vice president Bruce Nichols said in e-mail that “How We Decide” is coming off sale and will not be reissued. He did not specify what problems were found with the book. The announcement comes two weeks after Lehrer apologized for “frailties” and “weaknesses” that led to his firing. Lehrer’s first book, “Proust Was a Neuroscientist,” remains for sale. Lehrer, who used to live in Boston, was in years past an occasional contributor to the Globe’s Ideas section.
