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.

- The Fundamental Attribution Error
- When we try to understand the behavior of others, we often make a particularly human mistake. We tend
to attribute too much to character and disposition and too little to situation and context. When we
seek a better balance, we can adopt a more accepting view of events around us.
- Are You Micromanaging Yourself?
- Feeling distrusted and undervalued, we often attribute the problem to the behavior of others —
to the micromanager who might be mistreating us. We tend not to examine our own contributions to the
difficulty. Are you micromanaging yourself?
- Planning Your Getaway
- For many of us, taking a vacation can be a burden. We ask ourselves, "How can I get away now?"
And sometimes we have the answer: "I can't." How can we feel relaxed about taking time off?
- Compulsive Talkers at Work: Power
- Compulsive talkers are unlikely to change their behavior in response to your polite (or even impolite)
requests. In this second part of our exploration, we consider the role of power — both personal
- Power Affect
- Expressing one's organizational power to others is essential to maintaining it. Expressing power one
does not yet have is just as useful in attaining it.
Forthcoming issues of Point Lookout
- Coming April 25: Narcissistic Behavior at Work: VI
- Narcissistic behavior at work distorts decisions, disrupts relationships, and generates toxic conflict. These consequences limit the ability of the organization to achieve its goals. In this part of our series we examine the effects of exploiting others for personal ends. Available here and by RSS on April 25.
- And on May 2: Narcissistic Behavior at Work: VII
- Narcissistic behavior at work prevents trusting relationships from developing. It also disrupts existing relationships, and generates toxic conflict. One class of behaviors that's especially threatening to relationships is disregard for the feelings of others. In this part of our series we examine the effects of that disregard.

- 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.
