 The need to reflect intelligently on one’s conduct arises when the usual operation of habit or impulse is blocked. Customary means may be lacking; changed circumstances may make habits misfire, producing disturbing consequences; the social interaction of groups of people with different customs may produce practical conflicts that require mutual adjustment. Blocked habits lead people to deliberate on the problem posed by their situation. Deliberation is a thought experiment that aims to arrive at a practical judgment, action upon which is expected to resolve one’s predicament. Deliberation is more intelligent, the more articulate the definition of one’s problem in light of more observant uptake of its relevant features, the more imaginative and feasible are proposed solutions, the more comprehensive and accurate the estimate of the consequences of implementing them, and the more responsive is the choice to its expected consequences. As the individual gets more practice in intelligent conduct, the dispositions that make it up become habits (HWT 196–220).
