I think this is something that enters much of Western culture during the Reformation period 400 years ago, but it could be more recent and possibly during the 19th century in the USA. I'm convinced its because of Bible reading and the KJV. It is usually more accurate to call an unintentional lie 'Being wrong', because it specifies that you aren't intentionally deceiving or are negligent. Its harsh. In American culture, however, if you repeat a lie unintentionally you are actually lying. There is a responsibility not to pass on an untruth, both personal and organizational. You can fail in that responsibility and become the confederate of the original liar. Perhaps in recent years it has become unfashionable to call people liars, and its certainly impolite and not allowed on the forums here, but being wrong is technically being an unintentional liar. I'm not talking about criminal matters or legal matters. I think in legal circles the unintentional lie is termed 'Negligence', but the point of it is that people have a responsibility for one another.
