A systematic process of thinking about alternative futures and what the organization should do to anticipate and react
decision makers engage in confirmation bias to support
their implicit favourite and to maintain consistency in their
preference and decision.
Confirmation bias
Also know as postdecisional justification
Confirmation bias (postdecisional justification)
Underweight negative outcomes of the preference.
Inflates valence of the selected alternative.
Escalation of commitment
the tendency to repeat an apparently bad decision or allocate more resources to a failing course of action.
Causes of escalation:
Self-justification effect.
Self-enhancement effect.
Prospect theory effect.
Sunk costs effect.
Self-JustificationEffect
typically involves appearing to be rational and competent.
Decision makers are therefore motivated to demonstrate that their choices will be successful, which includes continuing to support a decision even when it is not having the desired outcomes.
Self-Enhancement
A person’s inherent motivation to have a positive self-concept (and to have others perceive them favourably), such as being competent, attractive, lucky, ethical, and important.
Self-justification
is a deliberate attempt to maintain a favourable public image.
self-enhancement
nonconsciously distorts our perceptions so problems are recognized later, and our probabilities of success are biased so we continue to invest in the losing project.
Prospect Theory Effect
tendency to feel stronger negative emotion from
losing a particular amount than positive emotion from
gaining an equal amount.
Prospect Theory Effect
This is also known as loss aversion
Sunk Costs Effect
the value of resources already invested in the decision.
Improving Decision Evaluation (Several strategies have been identified to minimize escalation of commitment and postdecisional justification.)
Change the decision maker.
Create a stop-loss.
Seek factual and social feedback.
Change the decision-maker’s mindset.
Change the decision maker
Decision evaluation biases are often minimized when those who made the original decision are replaced by those who later evaluate and act on that evaluation.
Create a stop-loss
Publicly establishing a preset level at which the decision is abandoned or re-evaluated forces the decision maker to abandon the investment if its value falls or cost overruns increase beyond a set level.
Seek factual and social feedback
At some point, even the strongest escalation and confirmation bias effects collapse when the decision maker is faced with systematic and clear feedback about the project’s failings.
Change the decision-maker’smindset
There is growing evidence that decision makers are less likely to engage in escalation of commitment if they change their mindset regarding the situation.
