I observe that in everyday life people routinely underestimate the power of language. Paying particular attention to punctuation marks as people were speaking to me, I learned to identify a more robust understanding in the meaning of their words, and many times they were mistaken in the way they transmitted their messages. Sentence structure and choice of words: Don't play with the knife. You will cut yourself. This is different from - you might cut yourself. It is different from the knife can cut you. It could take the form in someone's mind (conscious or subconscious) as a command, or as a rehearsal (that creates neural pathways of least resistance to be followed by behavior). This might be particularly dangerous to a hospitalized person under the influence of a drug or chemical that makes people more open to suggestion. The rehearsal might be dangerous to a person who has their inhibitions removed similarly by a drug or chemical (I'm thinking alcohol). I'm not sure how much woo is contained in Neuro Linguistic Programming, but for decades marketing people have been injecting symbols into advertising to entice people to act as a result of their messages. And today, especially with mass media resources, rhetoric sways the minds of masses who do not understand it. Yes, there is a serialized couch potato near me. It's time to bring Linguistics into the mainstream of American society by introducing it in secondary school, because language shakes the hand of understanding. The simplest concepts of Linguistics shield people against the tyranny of ignorance. People need to know the power of their language; how they are affected by it, and how they affect others when using it properly or carelessly.
