The Zaltman metaphor elicitation technique (ZMET) is a market research tool. ZMET is a technique that elicits both conscious and especially unconscious thoughts by exploring people's non-literal or metaphoric expressions. It was developed by Gerald Zaltman at the Harvard Business School in the early 1990s. As Zaltman described it, "A lot goes on in our minds that we're not aware of. Most of what influences what we say and do occurs below the level of awareness. That's why we need new techniques: to get at hidden knowledge-to get at what people don't know they know."[1] The technique has been used by academic researchers[2][3][4][5] and for marketing purposes to study a variety of topics related to both marketing and the social sciences.
