Real arguments. Hidden flaws. Sharper thinking.

Bad Arguments
Are Everywhere.
Can You Spot Them?

Every day, people try to convince you of something. In advertisements, social media posts, political speeches, and everyday conversations.

Some arguments sound convincing, even when the reasoning behind them doesn't hold up.

Think you can tell the difference?

Investigate Your First Case

No experience necessary. Just bring your curiosity.

A Polaroid clipped to the folder shows a hand holding a phone with a fictional headline claiming a study proves social media improves focus in teenagers.

What's a logical fallacy?

Sometimes an argument sounds right. Until you look closer.

A logical fallacy is a mistake in reasoning that can make a weak argument seem convincing.

Fallacies can appear in everyday conversations, news stories, advertisements, and more. They often sound reasonable, but they rely on faulty reasoning instead of sufficient evidence.

“Our school should start later. Other schools do it, so it must be a good idea.”

This is the
Bandwagon Fallacy.

Just because other schools do something doesn't automatically make it the best choice. Popularity alone doesn't prove an idea is right.

Why it matters

Your Best Defense Against Bad Arguments? Better Thinking.

Every day, you're surrounded by people trying to influence what you believe, buy, share, or support. Learning to recognize logical fallacies can help you:

  • Question what you see online

    Look beyond viral posts, catchy headlines, and confident claims.

  • Recognize misleading persuasion

    Examine the reasoning behind advertisements, debates, and public arguments.

  • Make stronger arguments

    Defend your ideas with evidence and reasoning rather than assumptions.

  • Challenge your own thinking

    Catch reasoning mistakes in your own beliefs, not only other people's.

How it works

Think Like a Detective. Question Like a Philosopher.

In Fallacy Files, you'll investigate arguments, uncover questionable reasoning, and learn to recognize the tricks that make bad arguments sound believable. Every case challenges you to look beneath the surface.

  1. Examine the evidence

    Read the argument and look for clues.

    A detective character presents an argument about building a new stadium, with an evidence card and case notes below.

  2. Find the flaw

    Identify where the reasoning breaks down.

    A cork case board with notes labeled Claims, Evidence, What's missing, and Possible Fallacy, connected by red string.

  3. Sharpen your skills

    Learn from each case and build your expertise.
