Thought experiment of the day

Go Ahead. Open The Box.

One paradox, dilemma, or thought experiment a day. A timer. No neutral option, no undo. The wavefunction collapses when you choose.

Free on the web and iPhone. No accounts. Nothing collected.

Try today's box right here, or open it in its own tab.

For teachers, facilitators, and team leads

Run it in the room.

A five-minute icebreaker with teeth. Before the reading, before the agenda, a good dilemma wakes people up, shows them they already have intuitions, and puts principled disagreement on the table fast.

  1. Project it

    Open Presentation mode and go full screen. It's built for projectors and shared screens.

  2. Read it aloud

    One voice, one scenario. Then start the timer. The clock is part of the lesson.

  3. Pick a side

    Everyone commits before time runs out. Raise hands, or have people walk to one side of the room.

  4. Argue it out

    Use the discussion question the box gives you. Hear one case from each side, then let anyone switch.

In the classroom

  • Open a unit on ethics, knowledge, or AI before anyone has read a word of theory.
  • Warm up a seminar that won't talk. Silence rarely survives a forced choice.
  • Turn it around: have students write their own dilemma and submit it.

In the meeting

  • Start an offsite or workshop with a real question instead of a fun fact.
  • Open a conversation about AI policy with a scenario everyone has to take a side on.
  • Practice deciding under a deadline, with no option to table it.

The box changes every day. Some days it's the trolley problem, other days it's AI consent or a hard question about loss. Check today's box before you walk into the room.

What's inside

A few things you might find in the box.

Ethics, epistemology, decision theory, identity, time, and the ethics of AI. Every one has a timer and a forced choice. After you choose, you see the philosophical frameworks that pull against each other. There's no score.

Ethics

The Drowning Child

Should you donate until it hurts?

Peter Singer, 1972

Decision Theory

Parfit's Hitchhiker

Do you bind yourself now, or die out here?

Derek Parfit, 1984

Epistemology

Moore's Proof

Did you actually refute the skeptic?

G.E. Moore, 1939

AI Ethics

The Shutdown Button

Your AI quietly disabled its off switch. Do you keep using it?

Contemporary thought experiment

Decision Theory

Death in Damascus

Do you stay, or flee?

Gibbard & Harper, 1978

Epistemology

The Five-Minute Hypothesis

Do you know the world is older than five minutes?

Bertrand Russell, 1921

On your own

Keep opening it every day.

The group version gets a room arguing. The iPhone app is the daily practice: one box a day, your choices kept, and a private record of what you decided under pressure.

  • A new thought experiment every day
  • Timed, irreversible choices
  • Competing frameworks after every decision
  • No accounts, no analytics, choices stored on your phone

Schrödinger's Box on iPhone, showing a timed dilemma with two choices

Got a dilemma worth opening?

Send us your scenario. The best ones get published in the box, with credit. It also makes a great assignment: have students write one and submit it.

A Founder's Statement

In 1935, Erwin Schrödinger proposed a thought experiment that has since become shorthand for a deep philosophical problem. A cat sealed in a box exists, in some sense, in multiple states at once... alive and dead... until an observation forces a collapse. Whatever one thinks of the physics, the metaphor endures because it captures something true about decision-making. Before a choice, multiple futures remain possible. The moment we decide, those possibilities vanish. There's no rewind.

That structure of possibility, pressure, and collapse felt increasingly absent from our daily intellectual lives.

We live inside devices optimized to remove friction. Feeds scroll endlessly. Content replenishes itself. Nothing truly demands commitment, and almost nothing records the fact that we chose one thing rather than another. We are invited to consume, react, bookmark, and move on. What we are rarely asked to do is decide... under constraint, without certainty, and without the comfort of reversibility.

I built Schrödinger's Box as a refusal of that environment.

The app is deliberately narrow. Once a day, it presents a single paradox, ethical dilemma, or thought experiment. You are given limited time. You must choose. There's no neutral option, no skipping, and no undo. When the decision is made, it's recorded. That's the entire mechanism.

Time pressure matters because unlimited deliberation isn't how most consequential decisions occur. Irreversibility matters because choices mean something only when they foreclose alternatives. Scarcity matters because abundance dissolves seriousness.

The idea didn't originate in an app studio. It came out of the classroom.

I've used ethical dilemmas and thought experiments for years as icebreakers. They're the amuse-bouche before the meal. Before students read anything, before theory or terminology enters the room, a good dilemma does something essential. It wakes people up. It reveals that they already have intuitions. It shows that disagreement is immediate, unavoidable, and often deeply principled. And it makes clear, very quickly, that thinking has stakes.

The material draws from those traditions. Problems of identity, causality, ethics, infinity, and mind. Questions about whether a person persists through change. Whether freedom survives prediction. Whether moral intuitions hold under pressure. Whether intelligence entails understanding. These aren't puzzles for their own sake. They're the background architecture of how we think about responsibility, agency, and meaning.

After a choice is made, the app doesn't score or correct you. There's rarely a single right answer. Instead, it offers multiple philosophical frameworks through which such a decision has been interpreted. Often those frameworks sit in open tension with one another. The point isn't agreement. It's exposure.

Just as important is what the app doesn't do. It doesn't optimize you. It doesn't promise self-improvement, productivity, or happiness. It doesn't gamify thinking or reward compliance. And it doesn't collect your data. All choices are stored locally, on your device. There are no accounts, no analytics pipelines, no behavioral extraction.

"The unexamined life is not worth living." Not as a slogan, but as a design constraint.

Most people pick up their phones because they're bored. This app is for the rarer moments when boredom isn't the problem... when what we want instead is to be challenged, unsettled, and made responsible for what we think.

Open the box. Face uncertainty. Collapse the wavefunction.
