I'd like to contend with the writer 1st answer / question: 1 - We're always wrong. Vocabulary is vital in accurately describing situation. I think dispassionate wording without using good / bad / right / wrong suits better to reflect what is really going on - process of continuous learning and continuous realigning of the information. People often get attached to ideas, ways of doing things. And they start attaching emotions to them. We should consider issues dispassionately while in analysis - this is hard: we are emotional beings. Appealing to our emotions is a way to deliver a message. However message should not be corrupted with fixed notions that some thing can be either wrong or right - as I think is happening in this article.
