This article describes three stages of my attempts to understand, measure, and develop creative thinking. The first stage explored creative intelligence. The second investigated a theory of creativity, the investment theory. The third proposed a theory of creative leadership. Together, these three stages comprise the development of my thought on creativity-its nature, measurement, and development.Keywords: creativity, abilities, motivation, personality, intelligence For roughly 25 years, I have been trying to understand creativity and its various aspects. Because this article is based on an American Psychological Association (APA) Division 10 Arnheim Award address for career achievement studying creativity, this seems like a good time to review what I think I have learned in 25 years.My goal has been to create some kind of vision of creativity: What is it, how can it be measured, how can it be developed? Over the course of the years, my attempts to understand creativity have gone roughly through three stages. The stages have not been wholly sequential. Sometimes I would proceed to a next stage, only later to go back to an earlier one. My goal always has been to broaden and deepen my, and, I hope, others' understanding of creativity.What has changed over the years are not the "answers." I have not found anything earlier that I later retracted or ceased to believe. Rather, what have changed are the questions. As time has gone on, the questions that have seemed important to ask have changed as my research interests have developed.
Stage 1: Creative Intelligence
Early Studies of IntelligenceMy earliest work was on intelligence (e.g., Sternberg, 1977Sternberg, , 1979. I was trying to understand the mental representations and processes involved in solving problems on intelligence tests. But after some number of years, I came to the conclusion that this approach was narrow, because the kinds of items used on these tests covered only a narrow range. My original "componential subtheory" of intelligence (Sternberg, 1980) came to seem too narrow. Instead of trying to understand intelligence only in terms of the components of analytical intelligence, I tried to understand as well other kinds of intelligence, in particular, creative and practical thinking. I proposed what I referred to as a "triarchic" theory of intelligence (Sternberg, 1984(Sternberg, , 1985. One of the three kinds of intelligence that I concerned myself with, the topic of discussion here, is creative intelligence. I then expanded my thinking to a theory of "successful" intelligence, which emphasized the importance not only of one's pattern of analytical, creative, and practical intelligence, but also of capitalizing on strengths and compensating for or correcting weaknesses (Sternberg, 1997a(Sternberg, , 1999a.
The Move to Studying Creative IntelligenceIntelligence tests contain a range of problems, some of them more novel than others. In some of our componential work, we have shown that when one goes beyond the range of unconventionality of the convention...
