Knowledge
Knowledge is a key component in decision theory. In the information processing model, knowledge is the “fuel” stored in long-term memory and released by short-term cues. Studies that measure knowledge using proxy indicators, such as the level or type of education or training, do not support the argument that increased knowledge on its own equates to better decisions. Pardue (1987) and Girot (2000) found that while critical thinking improved with the level of nurses’ educational attainment, the frequency of decisions and the perceived difficulty of the decisions themselves remained unaltered. Similarly, Westfall et al. (1986) showed that the number of hypotheses generated by students and graduates at different stages of their educational careers were no different, but the cognitive complexity of these hypotheses was greater in those at the higher educational levels (Hamers et al., 1994)., http://www.100md.com
