Answer
Some of the hindrances of rational decision maker by managers are;
• Cognitive biases
• Time pressure
• Group conflict
Explanation
Decision making process is controlled by an individual’s personality and behavioral traits. Objective judgments by managers can be disrupted by subjective biases. Cognitive biases such as halo effect and overconfidence can act as a barrier to rational decision making.
Time pressure can distort the process of making a rational decision thus resulting to less objective individual judgment which is influenced by intuition. Managers with ample time arrive at a more logical and highly crafted decision than those who feel they have insufficient time.
Both interpersonal and group dynamics can create a barrier towards making an effective decision.
