This study addresses the constraints given to the test items which have applied to the experimental
studies to deal with the creativity related topics. In general, most test items have two parts such as fixed
features and problem variables. While the later could be changed by problem solver, the former should
not be changed because it serves as a premise on the given test. Therefore, it should not be counted as
a creative solution if fixed features were changed by problem solver. Any suggestion from the solution on
the basis of changing the fixed feature must not be useful, rather it leads us to wrong way to generate
creative idea. The process how the fixed features are changed and the wrong but looks creative solution
was emerged is analyzed and some implications were discussed.
