Broken Window Fallacy

(also known as: glazier's fallacy)

Description: The illusion that destruction and money spent in recovery from destruction, is a net-benefit to society.  A broader application of this fallacy is the general tendency to overlook opportunity costs or that which is unseen, either in a financial sense or other.

This fallacy goes far beyond just looking for the silver lining, thinking positive, or making the best of a bad situation.  It is the incorrect assumption that the net benefit is positive.

Logical Form:

Disaster X occurred, but this is a good thing because Y will come, as a result.

Example #1:

Dad, I actually did America a favor by crashing your car.  Now, some auto shop will have more work, their employees will make more money, those employees will spend their money, and who knows, they might just come to your store and buy some of your products!

Explanation: I actually tried a variation of this argument when I was a kid -- it didn’t work, but not only did it not work, it is fallacious reasoning, and here is why: by crashing the car, a produced good is destroyed, and resources have to go into replacing that good as opposed to creating new goods.

Example #2:

The Holocaust was a good thing overall.  It educated future generations about the evils of genocide.

Explanation: This is a real argument, I kid you not.  People tend to overvalue their own gain (the education) and devalue the losses that are unseen (the unimaginable suffering of the victims and their families). 

Exception: It might be the case when some kind of destruction actually can benefit society -- like in lightning striking the local crack house, and a soup kitchen being reconstructed in its place.

Tip: Be sensitive when looking for the best of a bad situation, keeping in mind all those who may have suffered. In your statement of optimism or hope, be sure to show compassion as well.

The Holocaust was a horrible event in human history, and the damage that resulted will never be forgotten. As with most tragedies, they can be used to educate us, helping us to prevent similar future events.

Reason: Books I & II

This book is based on the first five years of The Dr. Bo Show, where Bo takes a critical thinking-, reason-, and science-based approach to issues that matter with the goal of educating and entertaining. Every chapter in the book explores a different aspect of reason by using a real-world issue or example.

Part one is about how science works even when the public thinks it doesn't. Part two will certainly ruffle some feathers by offering a reason- and science-based perspective on issues where political correctness has gone awry. Part three provides some data-driven advice for your health and well-being. Part four looks at human behavior and how we can better navigate our social worlds. In part five we put on our skeptical goggles and critically examine a few commonly-held beliefs. In the final section, we look at a few ways how we all can make the world a better place.
