When a manager is forecasting cash flows for a potential
project, the forecasts could have the following bias :
- Selective perception and confirmation bias - information that
supports the manager's pre-conceived notions could be given more
importance. All the available information is not neutrally
considered. Rather, that portion of information that inclines with
the manager's knowledge, interests, or subconscious decisions is
given selective preference. If the manager is intuitively convinced
that the project is unprofitable, any information to the contrary
could be filtered and any information that supports this view could
be given more importance than due.
- Recency bias - This is a type of bias where recent events are
given more weightage. If the manager had an extremely profitable or
extremely poor project recently, the learning from that project
could have an overbearing influence on the current project
- Overconfidence bias - This is a type of bias where the manager
has too much confidence in their analysis decisions. This could
lead to overstating cashflows or even understating them. The
underlying problem is that indepenence of judgement is
compromised
- Anchoring bias - This is where the initial information flow is
given overdue importance. In this type of bias, too much weightage
is given to one piece of information. Managers with this bias tend
to make decisions too early.
These are a few important biases in managerial decision
making.
To mitigate this bias, the manager could :
- Constantly challenge their own viewpoint. Do not assume
anything. Always question the basic assumptions in any
analysis.
- Discuss thoughts with others to understand multiple
perspectives. Play the devil's advocate
- Avoid making decisions under pressure. A slower but
well-thought decision is better than a hasty but wrong
decision
- Analyse the decision making process to delete any subjective
decisions. All decisions must be analytical and fact-based
- Review the information sources to make sure they are
accurate
