Maybe that's the new party line to defend the growing practice of sucking up memes, word coinages, sentences, paragraphs and music lyrics and not attributing them to the source.
In New York Magazine, Melissa Dahl presents that defense by Adam Grant, professor of management at the University of Pennsylvania's Wharton's School. He has labeled this behavior "kleptomnesia." And he acknowledges the coinage was first put out there by Harvard psychologist Dan Gilbert.
But to me, a former contract employee in loss prevention, this sounds like the petty thieves attempting to leave the store with merchandise they didn't pay for. Most acted shocked when apprehended. The generic statement was that they had mindlessly picked up the item, placed in a pocket or purse and simply forgot doing so. Clearly, this was no Nancy Drew mystery that I had to solve. It was arrogance, poorly masked as forgetfulness.
Perhaps then, I am jaded. Also, I am a crusader to expose and end theft of ideas and content. For example, a high-traffic tax blog reprinted content from this site and others such as Abovethelaw.com without attribution. Among its advertisers was The Economist. I notifed those advertisers.
Very quickly the tax blog posted the source for each post. Of course, I felt a sense of victory. No one should accept what is stealing. Everyone should take action. Rarely are careers ruined when the miscreants are uncovered. But I really don't care. Laboring in the trenches of loss prevention hardens us regarding the foibles of mankind.
