What are the personal characteristics that distinguish the creative scientist from the less creative scientist? This study used the concept of implicit theory in a four‐part study of scientists and graduate students in science. In the first part, we collected 1382 adjective words that describe the personal characteristics of the creative scientist from 354 scientists. In the second part of the study, 542 additional scientists assessed these adjectives. We determined that the personal characteristics of the creative scientist fit into four factors: personality, thinking ability, research ability, and uniqueness. In the third part of the study, we found that the concepts of thinking ability and uniqueness would positively predict 221 graduate students' self‐perceived creativity, and research ability would positively predict their creative motivation. The last part of the study involved having 283 creative scientists and 264 less creative scientists from 30 research institutions rated by three colleagues on the above four factors. A logistic regression found that thinking ability was best able to identify creative scientists while personality best predicted less creative scientists.
