2.4 Creativity and intelligence as disjoint sets
In this view，creativity and intelligence are completely different，unrelated constructs.
Getzels and Jackson administered 5 creativity measures to a group of 449 children from grades 6-12，and compared these test findings to results from previously administered（by the school）IQ tests.They found that the correlation between the creativity measures and IQ was r＝0.26.The high creativity group scored in the top 20% of the overall creativity measures，but they were not included in the top 20% of IQ scorers.The high intelligence group scored the opposite：they scored in the top 20% for IQ，but were outside the top 20% scorers for creativity，thus showing that creativity and intelligence are distinct and unrelated.
However，this work has been heavily criticized.Wallach and Kogan highlighted that the creativity measures were not only weakly related to one another（to the extent that they were no more related to one another than they were with IQ），but they seemed to also draw upon non-creative skills.McNemar noted that there were major measurement issues，in that the IQ scores were a mixture from 3 different IQ tests.
