People in creative roles may seem immune to others' input. The authors, who studied populations from toy developers to R&D scientists, say that creative types sometimes react in this way not so much because of ego but, rather, a sense of identity as an artist. The authors explore the particular characteristics of the "artist identity" and suggest four tactics for working with artists: (1) Offer broad suggestions. Artists may see specific, fully formed ideas as attempts to wrest creative control. Plant just the seed of a concept, and you inspire continued engagement. (2) Temper your enthusiasm. If you're too invested in your idea, you may imply that the artist can't contribute much. A dispassionate demeanor works better. (3) Delay decision making. Expect initial resistance, and give the artist ample time to consider your ideas on their merits. (4) Show respect and like-mindedness. Acknowledging an artist's prior thinking and work will reassure him or her that your ideas are not off-base.
