For the last 40 years, researchers have been working on techniques that make brainstorming effective and developing models that explain the generation of ideas. One of these is the Cognitive Stimulation Approach (Paulus et al., 2002), which assumes that the number of stimuli increases as the number of creative ideas increases. However, studies testing this model yield inconsistent results. For example, one study (Dugosh et al., 2000) found that original samples enhance creativity, while another study (Dugosh et al., 2005) found that ordinary samples leads to creativity. Besides, the effect of exposure to ideas from an abnormal individual (e.g., from a schizophrenic individual) and exposure to ideas from a normal individual was investigated in the literature. In this research, the participants were brainstormed on ways to develop the university within 10 minutes by being exposed to three idea samples. The participants exposed to ordinary idea samples generated more original and deep ideas than participants exposed to the original samples. Moreover, deep thinking was a partial mediation between exposure to ordinary examples of ideas and creative thinking. On the other hand, there was no significant difference between exposure to ideas from an abnormal individual (e.g., a schizophrenic individual) and the effect of exposure to ideas from a normal individual. These findings indicate that exposure to ordinary examples of ideas increases deep thinking and thus creativity. These findings, which first appeared in the literature, were discussed with new approaches.
