How would you know? Maybe you only spotted 1% of the lies people are telling you and you’re thinking they’re really bad at lying when they’ve effectively lied to you 99% of the time and you never found out.
I was tempted to ask: "how do you know?", but I will rather just state that I think you are wrong. In fact, I think most people are excellent liars, especially if lying about something they don't consider to be morally wrong.
