The hot hand fallacy is the belief that we can better estimate the outcome of tests of skill if we weigh recent results more heavily than less recent results. It was first identified by Gilovich, Vallone, and Tversky in 1985 [Gilovich 1985]. They found that the belief that basketball players can have "hot hands," leading to streaks of successful shooting, is without statistical foundation. That is, players do have "hot streaks" and "cold streaks," but the streaks that do happen are consistent with random chance.
Nevertheless, people do believe in the "hot hand," in basketball, and at work.
When someone has succeeded at a string of assignments, managers and executives tend to attribute that success, without proof, to the performer's innate capabilities. And the longer the string of successes, the more faith they have in the belief, even though every string of successes has a beginning, before which outcomes were less stellar.
When we believe someone has a "hot hand," we tend to ensure that he or she is fully occupied. Then, when a difficult challenge with a troubled history comes along, we sometimes try to fit it into whatever the hot-handed people are already doing. We add it to their responsibilities, hoping for yet another success. If it doesn't fit well, we make it fit. Voila! Scope creep.
But there's a little more to it. The people whom we regard as having a "hot hand" often regard themselves that way, too. They overestimate their capabilities, partly because of the hot hand fallacy, and perhaps partly due to another cognitive bias called the illusion of control. The illusion of control is our tendency to overestimate our ability to control events that are beyond our control.
For example, a project manager who completes a project successfully might not notice that she was able to retain all of her staff for the life of the project — no key people were suddenly reassigned to other projects. Scope creep often takes place
outside our awareness, due to
misjudgments arising from
cognitive biasesIn many organizations, such a record is rare. But a project manager exulting in success might not notice this fortunate turn of events. Most project managers cannot control these "staff raids," but when they don't happen, the project runs more smoothly. Project managers then might tend to attribute the project's success to their own performance, neglecting to attribute any of it to good fortune. Project managers, or any managers, who attribute successes to their own performance, ignoring good fortune, might be in the grip of the illusion of control. And someone in that state is more likely to accept additional responsibilities when they're offered. Voila! Scope creep.
This example suggests that two people under the influence of different cognitive biases might produce collaborative misjudgments more erroneous than either of them acting independently, if their respective cognitive biases interoperate synergistically.

- Resuming Projects: Team Morale
- Sometimes we cancel a project because of budgetary constraints. We reallocate its resources and scatter
its people, and we tell ourselves that the project is on hold. But resuming is often riskier, more difficult
and more expensive than we hoped. Here are some reasons why.

- Nonlinear Work: When Superposition Fails
- Much of the work we do is confounding, because we consistently underestimate the effort involved, the
resources required, and the time required to get it done. The failure of superposition can be one reason
why we get it wrong.

- Mountaineers often experience "false summits," when just as they thought they were nearing
the summit, it turns out that there is much more climbing to do. So it is in project work.

- The Race to the South Pole: The Power of Agile Development
- 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. Lessons abound. Among the more important
lessons are those that demonstrate the power of the agile approach to project management and product
development. Read more about this program. Here's

- 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.
