We all have a cranky uncle who thinks he knows better than the world’s scientists. But how do you make sense of his arguments and conspiracy theories? The way to understand your cranky uncle is to become a cranky uncle! If you’re going to spot someone cheating at cards, first you have to learn how to cheat at cards.

In this game, Cranky Uncle teaches you the rhetorical techniques and logical fallacies he uses to deny science. Climate change, evolution, vaccination, a round Earth - he’s never met a science he wouldn’t deny! The deeper you get into the game, the more resilient you become against misinformation.

Doesn’t Work

First it asks you to “sign in” by entering your email address, which I reluctantly did (no doubt my junk mail folder will get fuller faster now). Then it went to a “dot dot dot” waiting screen that never resolved, so I just clicked the back arrow to the sign-in page and discovered instead that I was on the Home Screen and I was signed in with my email (even though I never checked my email for confirmation). I was offered only a “take quiz” button on each topic, but every topic just skipped right to a “learn more techniques (?)…” button that didn’t do anything.

Fun Premise. Become “Cranky” as you learn to recognize deception

Maybe you can already recognize fake news and misinformation.

But , can you explain why it is misleading? The app has many examples of twisted logic, and invites you to learn which deception techniques are involved.

I hope people use this to reliably detect deception rather than to invent new deceptive arguments!
