“I prefer complex to simple problems (rational engagement)”
“I trust my initial feelings about people (experiential ability)”
“I like to rely on my intuitive impressions (experiential engagement)”
Reliability
Reported internal consistency: alphas 0.84–0.89. As a rule of thumb, Cronbach’s α ≥ .70 is considered acceptable, ≥ .80 good, and ≥ .90 excellent for established measures.
