There is some evidence that word choice dictates not only how we think but also how we act.
For example, subjects in Bargh's controversial experiment were reported to walk more slowly after reading text with words about the elderly than subjects who read text primed with words about youthful energy.
Also, sometimes people use the word "stress" to express "emphasize."
"Stress" suggests the idea of stress as an emotional response, while "emphasize" is more specific and less emotionally loaded-- less likely to suggest the idea of strain or pressure to a listener.
"Emphasize" may be worth its extra syllables because it doesn't evoke the idea of anxiety.
Another example, Daniel Tammet explains is the word choice of "hare" in lieu of "rabbit" to suggest wild frailty in a poem.
Are there other situations or word choices that are examples of linguistic relativism in that the choice may influence the human experience?
