The aim of the present study was to explore the hypothesized relationship between divergent thinking (DT) and two types of evaluation: interpersonal (judgments about others' ideas) and intrapersonal (judgments about one's own ideas). Divergent thinking and evaluation skills were measured by means of a GenEva (Generation and Evaluation) task. There were two conditions of the task: intrapersonal and interpersonal, and two aspects of a given idea were assessed: originality and uniqueness. The main results suggest that (1) overall DT skill is positively related to intrapersonal evaluation of uniqueness; (2) the originality component of DT skill is negatively related to intrapersonal evaluation of uniqueness; (3) overall DT is negatively related to intrapersonal evaluation of originality; (4) underestimation of idea uniqueness is more salient in interpersonal evaluation, particularly in case of those with high DT skill. The results are discussed in terms of author's and observer's perspectives of judgment.
