As we've seen, scope tends to expand, rather than contract. In Part I of this exploration, we briefly examined cognitive biases that lead us to avoid changes that would tend to contract scope. In this Part II we explore cognitive biases that lead us to favor proposals that tend to expand scope.
- Confirmation bias
- In the grip of confirmation bias we tend to favor information that confirms our beliefs and preconceptions. Although it operates when we're evaluating information, its most important effects for scope creep relate to its influence on information gathering. To the extent that confirmation bias influences them, those decision makers who have a preference for expanding the scope of an effort will tend to seek proposals that expand that effort's scope. This might include, among others, those decision makers who want to limit the total number of efforts underway, those who want to "piggy back" a favored capability on an effort already underway, and those who seek to enhance their power by expanding the scope of efforts they lead. For more, see "Scope Creep and Confirmation Bias," Point Lookout for March 12, 2014.
- Ambiguity effect
- The ambiguity effect is the human tendency to prefer options for which the probability of a favorable outcome is known fairly well, compared to options for which the probability of a favorable outcome is less known. When two projects, A and B, are both in trouble, and A is led by someone known to the decision makers, while B is led by someone less well known, the arguments contained in a proposal by A's leader to acquire B are likely to hold sway over B's counter-arguments, even when there are some doubts about A's likelihood of success and no evidence suggesting doubts about B's likelihood of success.
- Bias blind spot
- The bias blind spot [Pronin 2002] creates in humans a tendency to believe that they are not affected by cognitive biases. Scope expansion might be
inevitable. Instead of trying
to prevent it, we might do
better by learning
to exploit it.It causes decision makers to fail to compensate for cognitive biases in the decision process. An example of a cognitive bias compensation might be a review of the set of options under consideration, to ensure that scope-contracting approaches receive due consideration.
- The anchoring effect
- This bias causes us to assign too much importance to the first available piece of information. With regard to scope creep, that information might be an early proposal, or market research, or a senior management directive. For example, in the latter case, management might solicit proposals for cost reduction. Decision makers then might tend to become anchored on cost reduction, which could lead them to favor consolidating several projects, failing to even consider the possibility that any cost savings from consolidation might be surpassed by revenue advantages arising from earlier completion by continuing to operate those projects separately.
Most important, perhaps, is the Optimism Bias — the tendency to overestimate favorable and pleasing outcomes. Any proposal that manages to come up for a final decision is likely to be accepted if it promises success. First in this series Top Next Issue

More articles on Project Management:
- Restarting Projects
- When a project gets off track, we sometimes cancel it. But since canceling projects takes a lot of courage,
we look for ways to save them if we can. Often, things do turn out OK, and at other times they don't.
There's a third choice, between pressing on with a project and canceling it. We can restart.
- Scheduling as Risk Management
- When we schedule a complex project, we balance logical order, resource constraints, and even politics.
Here are some techniques for using scheduling to manage risk and reduce costs.
- Shining Some Light on "Going Dark"
- If you're a project manager, and a team member "goes dark" — disappears or refuses to
report how things are going — project risks escalate dramatically. Getting current status becomes
a top priority problem. What can you do?
- Deep Trouble and Getting Deeper
- Here's a catalog of actions people take when the projects they're leading are in deep trouble, and they're
pretty sure there's no way out.
- False Summits: II
- When climbers encounter "false summits," hope of an early end to the climb comes to an end.
The psychological effects can threaten the morale and even the safety of the climbing party. So it is
in project work.
Forthcoming issues of Point Lookout
- Coming August 23: Look Where You Aren't Looking
- Being blindsided by an adverse event could indicate the event's sudden, unexpected development. It can also indicate a failure to anticipate what could have been reasonably anticipated. How can we improve our ability to prepare for adverse events? Available here and by RSS on August 23.
- And on August 30: They Just Don't Understand
- When we cannot resolve an issue in open debate, we sometimes try to explain the obstinacy of others. The explanations we favor can tell us more about ourselves than they do about others. Available here and by RSS on August 30.

- The Race to the South Pole: Ten Lessons for Project Managers
- On 14 December 1911, four men led by Roald
Amundsen reached the South Pole. Thirty-five days later, Robert F. Scott and four others followed. Amundsen
had won the race to the pole. Amundsen's party returned to base on 26 January 1912. Scott's party perished.
As historical drama, why this happened is interesting enough, but to organizational leaders, business
analysts, project sponsors, and project managers, the story is fascinating. Lessons abound. Read

- Creating High Performance Virtual Teams
- Many people experience virtual teams as awkward, slow, and sometimes
frustrating. Even when most team members hail from the same nation or culture, and even when they all
speak the same language, geographic dispersion or the presence of employees from multiple enterprises
is often enough to exclude all possibility of high performance. The problem is that we lead, manage,
and support virtual teams in ways that are too much like the way we lead, manage, and support co-located
teams. In this program, Rick Brenner shows you how to change your approach to leading, managing, and
supporting virtual teams to achieve high performance using Simons' Four Spans model of high performance.

- The Power Affect: How We Express Our Personal Power
- Many people who possess real organizational power have a characteristic demeanor. It's the way they project their presence. I call this the power affect. Some people — call them power pretenders — adopt the power affect well before they attain significant organizational power. Unfortunately for their colleagues, and for their organizations, power pretenders can attain organizational power out of proportion to their merit or abilities. Understanding the power affect is therefore important for anyone who aims to attain power, or anyone who works with power pretenders. Read more about this program.
