|
The Six-Step Rational (Classical) Decision-Making Madel
|
|
Assumptions of the Model:
|
|
Perceptions linked to individual decision making
|
Perceptions affect awareness of problems
Perceptions affect analysis of problem Perceptions affect interpretations of data Perceptions affect judgments of potential outcomes (example community college) |
Bounded Rationality
|
Due to the limited capacity of the mind to be fully rational; decision makers construct simplified models to extract the essential features from complex. (amount of knowledge
|
Types of bounded rationality:
|
-Limited list of criteria based on most conspicuous choices
-Final solution represents a satisficing choice, not an optimum one -Satisficing first acceptable choice |
Judgmental Heuristics:
|
-Simplifying strategies or “rules of thumb” used to make decisions
-Makes it easier to deal with uncertainty and limited information -Can lead to systematic errors that affect the quality and/or ethics of decisions |
Availability heuristic
|
Bases a decision on recent events relating to the situation at hand
|
Representativeness Heuristic
|
Bases a decision on similarities between the situation at hand and sterotypes of similar occurrences
|
Anchoring and adjustment heuristic
|
Bases a decision on incremental adjustments to an intial value determined by historical precedent or some reference point
|
Common Biases and Errors
|
Overconfidence, Anchoring, Confirmation, Availability, Escalation of Commitment, Randomness error
|
Individual:
More Efficient Speed No Meetings No Discussions Clear Accountability |
Group:
More Effective More information and knowedge diversity of views (takes longer) |
GroupThink
|
Tendency of members to lose critical evaluative capabilities
Occurs within cohesive group "I don't want to rock the boat" |
Symptoms of Groupthink
|
-Group members reationalize any resistance to their assumptions.
- Members presure any doubters to support the alternatives favored by the majority - Doubters keep silent about misgivings and minimize their importance |
