Pay careful attention the next time you read the financial news. Agent metaphors describe price movements as the deliberate action of a living thing, as in, "The NASDAQ climbed higher." Object metaphors describe price movements as non-living things, as in, "The Dow fell like a brick." Researchers asked a group of people to read a clutch of market commentaries, and then predict the next day's price trend. Those exposed to agent metaphors had higher expectations that price trends would continue. They had those expectations because agent metaphors imply the deliberate action of a living thing pursuing a goal. If, for example, house prices are routinely described as climbing and climbing, higher and higher, people might naturally assume that that rise is unstoppable. They may feel confident, say, in taking out mortgages they really can't afford. That's a hypothetical example of course. But this is how metaphor misleads.
