(1) bullshit takes less work to create than to clean up, (2) takes less intelligence to create than to clean up, and (3) spreads faster than efforts to clean it up. Of course, they are just aphorisms. They sound good, and they feel “truthy,” but they could be just more bullshit. In order to measure bullshit’s spread, we need an environment where bullshit is captured, stored, and packaged for large-scale analysis. Facebook, Twitter, and other social media platforms provide such environments.

Publicly, Filippo de Strata fretted that that the “brothel of the printing press” would lead readers to cheap, salacious entertainment—the works of Ovid, even. Privately, he may have been more concerned about his own job security.

The Internet site is not necessarily designed to perpetuate a long-term relationship; it is designed to make you click, now. Quality of information and accuracy are no longer as important as sparkle.

the curse of dimensionality. If you add enough variables into your black box, you will eventually find a combination of variables that performs well—but it may do so by chance. As you increase the number of variables you use to make your predictions, you need exponentially more data to distinguish true predictive capacity from luck.

more serious rebuttals in your professional life, the presentation is as important as the argument. As we tell our students, effective refutation is hard work. For us, creating a clear presentation often requires creating and refining visualizations, developing a null model, creating a synthetic data set, testing the argument with friends, and double-checking to be sure we are not missing anything.

The bad news is that we can’t possibly do this for every piece of bullshit that we find. Pick your battles. And when you have found your battle, make sure you win it. Do your homework in advance, and be clear in expressing your rationale.
