Decision-Making Flashcards
Decision-Making
What is Decision Making?
- Decision making is the process of developing a commitment to a course of action or choice.
- It's also the process of problem-solving, where a problem is the gap between the current state and the desired state.
Well-Structured Problem
- A well-structured problem is one where the existing state, desired state, and how to get from one state to the other are clear
- Outcome: clear/obvious
- May have past experience with the problem or standardized methods to solve it.
Ill-Structured Problem
- An ill-structured problem is one where the existing state, desired state, and how to get from one state to the other are unclear or unknown.
- Outcome: unpredictable
- Complex and has a high degree of uncertainty.
Rational vs. Intuitive Decisions
System 1
- Fast
- Unconscious
- Automatic
- Used for everyday tasks
- Error prone
System 2
- Slow
- Conscious
- Effortful
- Used for complex issues
- More accurate
Rational Decision-Making
- How decisions 'should' be made.
- Process of choosing a course of action out of a number of different alternatives.
- Aims to make consistent, value-maximizing choices within specified constraints.
- Assumes complete information.
- Identifies all relevant options in an unbiased way.
- Chooses the option with the highest quality.
Rational Decision Model
- Define the problem.
- Identify the criteria.
- Allocate weights to the criteria.
- Develop alternatives.
- Evaluate the alternatives.
- Select the best alternative.
Is ‘Rational’ Decision Making Realistic?
- The question of whether rational decision-making models reflect how we actually make decisions is posed
- Many management theories are based on economics, which treats economic agents as opportunistic
- Evidence suggests that this is not the case because there are too many assumptions with the model
Rational Model Assumptions
- Problem clarity:
- The problem is clear and unambiguous
- Known options:
- The decision-maker can identify all relevant criteria and viable alternatives
- Clear preferences:
- The criteria and alternatives can be ranked and weighted
- Constant preferences:
- Specific decision criteria are constant and the weights assigned to them are stable over time
- No time or cost constraints:
- Full information is available because there are no time or cost constraints
- Maximum payoff:
- The chosen alternative will yield the highest perceived value
Actual Decision-Making
- Bounded Rationality
- Satisficing
- Intuition
- Judgment shortcuts
Bounded Rationality
- Perfect rationality:
- A decision strategy that is completely informed, perfectly logical, and oriented toward economic gain
- Bounded rationality:
- Limitations on a person’s ability to interpret, process, and act on information
- Limitations include:
- Political constraints
- Resource constraints (information, time, money)
- Ourselves
Satisficing vs. Maximizing
- Satisficing:
- Accepts 'good enough'.
- Doesn't obsess over other options.
- Can move on after making a decision.
- Happier with outcomes.
- Maximizing:
- Exhaustively seeks the best.
- Compares decisions with others.
- Expends more time and energy.
- Unhappier with outcomes.
Perception
- The process by which individuals select, organize, and interpret their impressions to give meaning to their environment.
- Your brain’s filter – what info gets in and what doesn’t
Why Perception Matters
- Employment interviews – first impressions are powerful
- Performance expectations – expectations become reality
- Performance evaluations – typically subjective
Perceptual Error
- Perception takes time and effort, so we often take perceptual shortcuts
- We can only take in certain stimuli
- Selective perception
Attribution Theory
- When we observe behavior, we attempt to determine whether the cause is:
Determinants of Attribution
- Distinctiveness – if the person displays different behaviors in different situations.
- Consensus – if everyone who faces a similar situation responds in the same way.
- Consistency – if the person responds the same way over time to the same situation.
Attribution Chart
- Observation of individual behavior leads to interpretation of cause (internal or external).
- Distinctiveness:
- High distinctiveness leads to external attribution.
- Low distinctiveness leads to internal attribution.
- Consensus:
- High consensus leads to external attribution.
- Low consensus leads to internal attribution.
- Consistency:
- High consistency leads to internal attribution.
- Low consistency leads to external attribution.
Self-Serving Bias
- When we are successful, we focus on internal factors.
- When we fail, we blame external factors.
Fundamental Attribution Error
- In others, we tend to underestimate the external factors and overestimate internal factors.
- Especially when others are unfamiliar and their behavior is negative.
Attribution Bias Summary
- Self:
- Success: Internal
- Failure: External
- Bias: Self-serving bias
- Other:
- Success: External
- Failure: Internal
- Bias: Fundamental attribution error
Halo Effect
- Drawing a general impression about an individual based on a single characteristic, such as intelligence, likeability, or appearance.
Contrast Effect
- A person’s evaluation is affected by comparisons with other individuals recently encountered.
- Strong/weak competition will make you seem better/worse.
Intuition
- Non-conscious process created from experiences
- Quick decisions
- Past experiences
- Holistic associations
- Affectively charged – engaging the emotions
Heuristics & Cognitive Biases
- Mental shortcuts
- Heavy reliance on everyday lives
- Efficient but not always accurate à Systematic and predictable errors or cognitive biases
Overconfidence Bias
- Believing too much in our own ability to make good decisions – especially when outside of own expertise.
- The weaker the ability, the more likely to overestimate performance/ability.
Dunning-Kruger Effect
- Low-ability individuals think they are better than they are
- You need a certain level of skill/knowledge in an activity to realize how truly bad you are.
Confirmation Bias
- Selecting and using only facts that support our decision.
- Examples in:
- Journalism
- Hiring/promotion
- Science
Availability Bias
- Emphasizing information that is most readily at hand (recent & vivid).
- Risk of death examples:
- Airplane crashes: 1/11 million
- Shark attack: 1/3.7 million
- Car crashes: 1/500
Retrievability Bias
Note: There was no content in the transcript for the heading 'Retrievability Bias.'
Hindsight Bias
- Tendency to believe we could accurately predict the outcome, after the outcome of the event is known.
- Reduces our ability to learn from the past.
Planning Fallacy
- The tendency of people to underestimate the duration of time to complete a specific task or project.
- When we predict our own tasks, we tend to show an optimistic bias (underestimating time).
- When others predict task completion time, they show a pessimistic bias (overestimating time).
- Potential explanations:
- Not taking our experience into consideration
- Wishful thinking
- Self-serving bias
- Framing
Prospect Theory
- A theory that describes the ways in which people make decisions based on the potential value of losses and gains rather than the final outcome.
Risk Aversion
- The tendency to prefer a sure gain over a risker outcome.
- People prefer to take chances to prevent a negative outcome.
Framing
- Presenting one of two equivalent value outcomes either in positive or gain terms (positive framing) or in negative or loss terms (negative framing).
- The starting point of individuals’ decisions is contained by the ways in which information is presented to them.
Sunk Cost Fallacy
- Continue to rationalize decisions, actions, and investments in an existing cost despite increasingly negative outcomes.
- A cost that has already been paid and thus cannot be recovered.
- Sunk costs are permanent losses of resources incurred as the result of a decision.
Escalation of Commitment
- Escalation of commitment is repeating or further investing in an apparently bad decision.
- Causes of escalation:
- Self-justification effect
- Self-enhancement effect
- Prospect theory effect
- Sunk costs effect
Emotions and Making Choices
- Emotions form preferences before conscious evaluation.
- Moods and emotions affect the decision process.
- Emotions serve as information in decisions.
Emotions Affect Decision-Making
- Affective states can affect the decision-making process:
- Positive Affect
- Prompts more creative thinking and greater cognitive flexibility
- Irrational optimism (similar to overconfidence)
- Negative Affect
- Anger induces more rigid thinking and quicker decision-making
- Sadness reduces cognitive flexibility BUT reduces overconfidence
Kahneman et al., 2011 - Before You Make That Big Decision
- Is there any reason to suspect motivated errors, or errors driven by the self-interest of the recommending team? (self-interested biases)
- Has the team fallen in love with its proposal? (affect heuristic)
- Were there dissenting opinions within the team? (group think)
- Could the diagnosis be overly influenced by an analogy to a memorable success? (saliency bias)
- Are credible alternatives included along with the recommendation (confirmation bias)
- If you had to make this decision again in a year’s time, what information would you want, and can you get more of it now? (availability bias)
- Do you know where the numbers came from? (anchoring bias)
- Is the team assuming that a person, organization, or approach that is successful in one area will be just as successful in another (halo effect)
- Are the recommenders overly attached to a history of past decisions (sunk cost)
