Car ride. Hana: “I like the new album, but it’s mixed so loud that the vocals get buried under the drums.” Kwame: “Not every album has to be soft acoustic stuff. Some music is supposed to hit hard, and that’s fine.”

What you’ll practice

  • Practice on arguments that sound real.

    Every example is written the way someone would actually say it, about sports, music, films, money, school and the issues people really argue about. In Debates, you judge 12 whole conversations line by line.

  • Catch the flaw, respect the fair point.

    Calling a fair point a fallacy is a mistake too: a false alarm. In 199 of the 744 questions the reasoning is fine, and every lesson shows when an argument that looks like a fallacy isn’t one.

  • Point to the jump, then name it.

    In Spotter, longer arguments ask you to tap the sentence where the reasoning breaks before you name it. Rounds move from Warm-up to Close calls to Full strength as you improve, and the higher stages ask for names from memory.

  • Tell the look-alikes apart.

    Straw man or red herring? Ad hominem or tu quoque? Tell them apart drills close cousins side by side, including mirror pairs: the same reply, fair after one setup and a fallacy after the other.

  • Learn to answer, not just to name.

    Knowing the Latin doesn’t help mid-conversation. Every question ends with a fair reply you could actually say, and every lesson shows that reply in use.

  • From the everyday classics to the sneaky ones.

    74 fallacies in four tiers, from ad hominem to the motte-and-bailey, each checked against sources such as the Stanford Encyclopedia of Philosophy. Master one and Straw gets a plate of steel armor.

Why it exists

I’ve been arguing about religion, philosophy and politics since high school. For years I hit the same wall: someone made an argument that sounded reasonable, I saw exactly where it broke, explained it, and watched the explanation bounce off. Nobody learns logic in the middle of defending something they care about.

What I had wasn’t a talent. It was a reflex, built by years of practice. Steelman is that practice, on arguments that sound like real life, and it counts false alarms too, because shouting “fallacy!” at everything isn’t clear thinking either.
