No. Because scientific findings are open to public scrutiny and replication, any errors and faulty reasoning that become apparent should lead to a change in the conclusions we reach. For example, some early American psychologists, such as James McKeen Cattell, once believed that intelligence was directly related to the quality of one's nervous system; the better the nervous system, the higher the intelligence (see Goodwin, 2005). To verify this predicted relation, Cattell attempted to demonstrate that college students with faster reaction times (therefore, having better nervous systems) earned higher grades in college (had higher levels of intelligence). However, his observations failed to support the predicted relation, and Cattell changed his view of intelligence and how to measure it.
