Esquire has an article about Radical Honesty, a movement founded by psychotherapist Brad Blanton. He says everybody would be happier if we just stopped lying. Tell the truth, all the time. This would be radical enough — a world without fibs — but Blanton goes further. He says we should toss out the filters between our brains and our mouths. If you think it, say it. Confess to your boss your secret plans to start your own company.
