The external validity of existing creativity tests was examined in the product-design field. To examine the external validity, this study adopted the Consensual Assessment Technique (CAT), by which industry leaders directly rate product ideas for their creativity. A simple correlation analysis showed that among three broadly used creativity tests (Remote Associations Test, Alternative Uses Test, and Torrance Test for Creative Thinking), only the Alternative Uses Test (AUT) was found to predict creativity in the product-design industry. In addition to the correlations analysis, two factors, product familiarity and level of interest, were tested for moderation. The results show that familiarity with the product lessens RAT-CAT (Remote Associations Test - Consensual Assessment Technique) correlation, whereas level of interest strengthens the correlation. Thus, the less familiar and more interested an individual is in the product, the more likely the individual's divergent thinking skills will translate into an actual creative product idea.
