 The researchers also looked for divergent validity in Study 2, and the results showed that the CNS does not correlate with academic tests, such as the SAT, showing its divergent validity.The goals of Study 3 were to test if the CNS could predict real life decisions and to further establish the validity.The researchers hypothesized that students studying environmental studies would score higher than psychology, math, or chemistry students since the former are already showing motivation to study the environment.
