- Coming February 20: Brainstorming and Speedstorming: I
- Recent research suggests that brainstorming might not be as effective as we would like to believe it is. An alternative, speedstorming, might have some advantages for some teams solving some problems. Available here and by RSS on February 20.
- And on February 27: Brainstorming and Speedstorming: II
- Recent research into the effectiveness of brainstorming has raised some questions. Motivated to examine alternatives, I ran into speedstorming. Here's Part II of an exploration of the properties of speedstorming. Available here and by RSS on February 27.

- Effects of Shared Information Bias: II
- Shared information bias is widely recognized as a cause of bad decisions. But over time, it can also erode a group's ability to assess reality accurately. That can lead to a widening gap between reality and the group's perceptions of reality.

- Effects of Shared Information Bias: I
- Shared information bias is the tendency for group discussions to emphasize what everyone already knows. It's widely believed to lead to bad decisions. But it can do much more damage than that.

- The Ultimate Attribution Error at Work

- Cognitive Biases and Influence: II
- Most advice about influencing others offers intentional tactics. Yet, the techniques we actually use are often unintentional, and we're therefore unaware of them. Among these are tactics exploiting cognitive biases.

- Cognitive Biases and Influence: I
- The techniques of influence include inadvertent — and not-so-inadvertent — uses of cognitive biases. They are one way we lead each other to accept or decide things that rationality cannot support.

- Wishful Significance: II
- When we're beset by seemingly unresolvable problems, we sometimes conclude that "wishful thinking" was the cause. Wishful thinking can result from errors in assessing the significance of our observations. Here's a second group of causes of erroneous assessment of significance.

- Wishful Significance: I
- When things don't work out, and we investigate why, we sometimes attribute our misfortune to "wishful thinking." In this part of our exploration of wishful thinking we examine how we arrive at mistaken assessments of the significance of what we see, hear, or learn.

- Overconfidence at Work
- Confidence in our judgments and ourselves is essential to success. Confidence misplaced — overconfidence — leads to trouble and failure. Understanding the causes and consequences of overconfidence can be most useful.

- Historical Debates at Work
- One obstacle to high performance in teams is the historical debate — arguing about who said what and when, or who agreed to what and when. Here are suggestions for ending and preventing historical debates.

- Why Scope Expands: II
- The scope of an effort underway tends to expand over time. Why do scopes not contract just as often? One cause might be cognitive biases that make us more receptive to expansion than contraction.

- Why Scope Expands: I
- Scope creep is depressingly familiar. Its anti-partner, spontaneous and stealthy scope contraction, has no accepted name, and is rarely seen. Why?

- Scope Creep and Confirmation Bias
- As we've seen, some cognitive biases can contribute to the incidence of scope creep in projects and other efforts. Confirmation bias, which causes us to prefer evidence that bolsters our preconceptions, is one of these.

- Scope Creep, Hot Hands, and the Illusion of Control
- Despite our awareness of scope creep's dangerous effects on projects and other efforts, we seem unable to prevent it. Two cognitive biases — the "hot hand fallacy" and "the illusion of control" — might provide explanations.

- Scope Creep and the Planning Fallacy
- Much is known about scope creep, but it nevertheless occurs with such alarming frequency that in some organizations, it's a certainty. Perhaps what keeps us from controlling it better is that its causes can't be addressed with management methodology. Its causes might be, in part, psychological.

- Managing Hindsight Bias Risk
- Performance appraisal practices and project retrospectives both rely on evaluating performance after outcomes are known. Unfortunately, a well-known bias — hindsight bias — can limit the effectiveness of many organizational processes, including both performance appraisal and project retrospectives.

- Self-Serving Bias in Organizations
- We all want to believe that we can rely on the good judgment of decision makers when they make decisions that affect organizational performance. But they're human, and they are therefore subject to a cognitive bias known as self-serving bias. Here's a look at what can happen.

- The Focusing Illusion in Organizations
- The judgments we make at work, like the judgments we make elsewhere in life, are subject to human fallibility in the form of cognitive biases. One of these is the Focusing Illusion. Here are some examples to watch for.

- The Paradox of Confidence
- Most of us interpret a confident manner as evidence of competence, and a hesitant manner as evidence of lesser ability. Recent research suggests that confidence and competence are inversely correlated. If so, our assessments of credibility and competence are thrown into question.
