Final answer:
Decision-making styles vary along the dimensions of intuitive versus deliberate, and instrumental versus expressive factors.
Step-by-step explanation:
Decision-making styles vary along two main dimensions which are often described in the context of psychological and behavioral studies. The first dimension is whether the decision-making is intuitive or deliberate. Intuitive decision-making, sometimes described as 'thinking fast', is quick, automatic, and often based on gut feelings. On the other hand, deliberate decision-making, or 'thinking slow', is more reflective, rational, and typically requires conscious effort and analysis.
The second dimension is whether the decision-making is influenced by instrumental (strategic) or expressive (noninstrumental) factors. Instrumental decision-making is goal-oriented, focusing on the outcomes and weighing the benefits of different options before making a choice. Expressive decision-making, however, is influenced by emotions, values, beliefs, and identity, and may not necessarily aim for the optimal outcome as per conventional standards.
