Right from the start, most children are taught by their parents, teachers, and guiding figures that lying is bad, and telling the truth is good. For the most part, people listen to that advice, I would like to think.
Sure, most people will tell the occasional “white lie” or harmless half truth, but I don’t think most people outright lie on a regular basis. Certainly, most people don’t lie in their professional career.
I don’t know if Jerry Colangelo just didn’t teach his son Bryan about the harms of lying, or if maybe it was something he picked up in his time at Cornell University with all of those meddling Ithacans, but Colangelo clearly has been less than aware of how telling lies can hurt his reputability and his career as a whole.
