Ginny was getting pretty steamed. "We tried code inspections back in Release 5, and you know what happened then. Everything slowed down, we got nothing done, everyone got into fights, and Morgan left the group. If we have to do inspections, you can count me out." Ginny's argument, in essence, was that since some unpleasant events happened shortly after inspections began, the code inspections caused them.
Arguments based on the
Fallacy of the False Cause
to make costly errorsAlthough her argument is convincing to many, it doesn't prove her case. It's an example of a rhetorical fallacy called post hoc ergo propter hoc — Latin for "after this, therefore because of this." Ginny argues that since the unpleasant events followed the adoption of code inspections, the code inspections caused the problems, and therefore all code inspections, of any kind whatever, are bad.
The Post Hoc fallacy is a special case of a more general type of fallacy — the fallacy of the false cause. In Post Hoc, the apparent causal connection relates to the timing of the two events. But connections can also be unrelated to timing:
All of the projects Gerhard has managed in the past few years have been late and over budget. Since people now believe that Gerhard was the cause of the overruns, he can no longer get assignments as a project lead. Nobody seems to remember that each of Gerhard's project sponsors had either reduced his budget or expanded requirements so many times that no project manager would have had much of a chance to perform well.
Gerhard's management skill was the most obvious factor common to the failed projects, but it wasn't the cause. In this case, faulty reasoning damages a career and deprives the company of a skilled manager.
How can you spot this kind of error in the heat of debate? The fallacy of the false cause might be lurking if the argument states that:
Since A was present when B occurred, then A was the cause. Or Since A preceded B, A caused B.
To respond to arguments that use this fallacy, use examples in which A was present, but B wasn't. Your debate partner might not be convinced, but it's your best shot.
Educate your colleagues about the Fallacy of the False Cause. When we understand how much it can cost, and when we understand how to avoid it, we can save much pain and frustration. Perhaps Will Rogers said it best (though the thought has been attributed to many others as well):
It's not what we don't know that hurts; it's what we know that ain't so.

- Are You Taking on the Full Load?
- Taking on the full load is what we do when we feel fully responsible for either the success or the failure
of some organizational activity. Instead of asking for help, we take extreme measures to execute responsibilities
that might not even be ours.
- The Unappreciative Boss
- Do you work for a boss who doesn't appreciate you? Do you feel ignored or excessively criticized? If
you do, life can be a misery, if you make it so. Or you can work around it. It's up to you to choose.
- It's a Wonderful Day!
- Most knowledge workers are problem solvers. We work towards goals. We anticipate problems as best we
can, and when problems appear, we solve them. But our focus on anticipating problems can become a problem
in itself — at work and in Life.
- 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 Problem of Work Life Balance
- When we consider the problem of work life balance, we're at a disadvantage from the start. The term
itself is part of the problem.

- When we disagree about abstractions, such as a problem solution, or a competitor's strategy, the cause can often be misunderstanding the abstraction. That misunderstanding can be a conceptual mondegreen. Available here and by RSS on December 20.
- And on December 27: On Assigning Responsibility for Creating Trouble
- When we assign responsibility for troubles that bedevil us, we often make mistakes. We can be misled by language, stereotypes, and the assumptions we make about others. Available here and by RSS on December 27.

- Person-to-Person Communications: Models and Applications
- When we talk, listen, send or read emails,
read or write memos, or when we leave or listen to voice mail messages, we're communicating person-to-person.
And whenever we communicate person-to-person, we risk being misunderstood, offending others, feeling
hurt, and being confused. There are so many ways for things to go wrong that we could never learn how
to fix all the problems. A more effective approach avoids problems altogether, or at least minimizes
their occurrence. In this very interactive program we'll explain — and show you how to use —
a model of inter-personal communications that can help you stay out of the ditch. We'll place particular
emphasis on a very tricky situation — expressing your personal power. In those moments of intense
involvement, when we're most likely to slip, you'll have a new tool to use to keep things constructive.

- Ten Project Management Fallacies: The Power of Avoiding Hazards
- Most of what we know about managing projects is useful and effective, but some of what we know "just ain't so." Identifying the fallacies of project management reduces risk and enhances your ability to complete projects successfully. Even more important, avoiding these traps can demonstrate the value and power of the project management profession in general, and your personal capabilities in particular. In this program we describe ten of these beliefs. There are almost certainly many more, but these ten are a good start. We'll explore the situations where these fallacies are most likely to expose projects to risk, and suggest techniques for avoiding them. Read more about this program. Here's a date for this program:
- 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.
