Metaphor is also a powerful way of shaping the way we think about things. Advertisers, politicians, newscasters know this. For example, when the US was fighting the First Gulf War, General Schwarzkopf said that a certain attack would be a "Hail Mary pass." Now that metaphor cast the US Armed Forces in the underdog role, and thus elicited more sympathy for the war by the US public. (Or at least that was the goal).
Metaphors force us to think and confront ideas in new and different ways. We use lots of metaphors implying fighting/war when we're talking about cancer, specifically. We fight, we battle, we're survivors, etc. Some studies have shown that these metaphors can have a negative effect on some patients who don't believe they're going to win. The mindset of battle can actually have a negative consequence.
Metaphor also is used by students who receive a grade. "I got an A." As a teacher, I have thought about "giving the student a grade." The downside is it implies that the student is given the grade and the teacher is giving, which is top-down. The teacher is higher and handing the grade down. It can even imply, at least in many students' thinking that I've noticed, that the student has no control over the grade. I've been thanked for giving a certain grade and I try to explain that it was their work and effort. Now, I'm thinking about a different metaphor for grading. How about "show"? I guess the fancy word is "demonstrated", but I think it easier for students to think of "showing" or "displaying" something. The responsibility then shifts from teacher to student. It also takes some of the stigma off a grade, I think. The student may be a great reader, but write little and talk little about their reading. If we let the metaphor of "show" sink in to the culture at large, the student, and parents hopefully, will understand that low grade in reading is only on what they have "shown" or "displayed." As I say to students often, "I'm not a mind reader. I can only go by what you show me. If you hand me a blank page, well I don't have much of a choice, do I?" I really wonder
