What Is Whysaurus?

Whysaurus is a place to enjoy a good argument, meet smart folks with new perspectives, and find the best arguments.

It’s designed to make online argument fun.

Why Argument?

Argument stinks online and it’s getting worse offline.

This is bad — and the stakes are high:

Argument, based in evidence, is how we figure out answers to hard problems. The internet is our new public square, and for democracy to function, we desperately need a platform that cultivates good argument.

What’s the goal?

To create a brilliant community and work together to create The Library of The Best Arguments for Every Idea.

What about the trolls?

Whysaurus' design uses principles from "structured argument" — so it will be easier to filter trolling on Whysaurus than most traditional forums.

What is Evidence in Whysaurus?

Evidence on Whysaurus is a chain of bite-sized claims.

What are Claims in Whysaurus?

Claims can be:

  • Supported or countered by other claims
  • Rated with agree/disagree
  • Re-used (along with their networks of evidence!)

What are Sources in Whysaurus?

Each claim can link to sources. But remember — IRL and on Whysaurus — arguments work best when you explain the best claims made by your sources.

“Because they said so” doesn’t work when we don’t agree on who to trust. Plus, even the best sources are wrong sometimes.

The good news is that we can all get behind “show me the evidence!”

I want to state a “fact” — how do I do that in Whysaurus?

A fact is a claim with real strong evidence. So make your claim and back it up! No claims are sacred cows — we must protect the right to argue against any claim.

How are Claims scored in Whysaurus?

A claim’s score is based on:

  • The scores of its Evidence (multiplied by Relevance)
  • Agrees and Disagrees
  • Sources

Supporting evidence makes scores go up; counter evidence makes scores go down. The algorithm uses "Bayesian Thinking", and it's a work-in-progress. Currently it only “looks” one level down. In the future, it will be possible to defend a claim by attacking its counter points! That stats display is going to get better too. And yes, we've got plans for trolls.

How does Relevance impact scores?

Relevance impacts scoring dramatically. For example:

a +10 Supporting claim with 20% Relevance adds only +2 to the claim above it (10 × 20% = 2).

When a piece of evidence is 0% Relevant, it has no effect on scores.

What is Relevance and how’s it differ from Agree/Disagree?

Relevance is one of the most powerful weapons in Whysaurus.

The links between claim are rated with Relevance. If someone claims “Tom Brady is a cheater” and supports that with “Star Wars stole ideas from Asimov’s Foundation series”, you might click “agree” on both, but rate Relevance as 0%.

Claims with low relevance are hidden by default.

What if the score of a claim is wrong?

Set the record straight! Add evidence or counter evidence. Vote on relevance and click agree/ disagree. Share the argument with friends and ask them to do the same!

Is "agree", "disagree" and "relevance" voting anonymous?

Yes. This way, peer pressure from friends, family, employers and governments can't influence votes. We keep count so you can't vote twice.

Why should I trust the crowd when it comes to truth?

So far, we’ve found that asking for evidence makes folks more likely to argue in good faith. Research by some really smart friends of ours has shown that when you ask people to explain a problem, they take more moderate positions than they would otherwise.

That said, if we see crowds of users clicking agree/disagree on iffy claims, we reserve the right to ask for evidence before tallying those votes.

How will Whysaurus prevent arguments from being overrun by trolls, bots, demons and armies of special interest lemmings?

We can compare suspicious activity to known humans acting in good faith. Our estimations will get better as we grow.

How is Evidence sorted?

By Relevance. So the most relevant claims rise to the top. In the case of ties, we look at scores.

Why are claims reusable and why is Whysaurus collaborative?

So you can build good arguments faster!


  • 1. Gus argues “No one ever died from overdosing on marijuana” and adds evidence.
  • 2. Later, Susannah argues “Marijuana is safer than alcohol” and links to Gus’s claim.
  • 3. All of Gus’ supporting evidence comes in automatically.

Why should we start from scratch when we can stand on the shoulders of the best work thats been done so far?

How does Clarification work in Whysaurus?

Click the little speech bubble icon in the byline. That opens the Meta channel, where you can hammer out the best phrasing.

If you don’t agree with how other users are framing a discussion, start your own argument!

Oops I messed up! Can I delete my claim?

If you created a claim and it has no other contributors, you can delete it. Click the icon and the delete button should be in the menu. Once multiple contributors are involved, only admins can delete. If you see a claim you think should be trashed, contact us.

Best Practices

Community rules

  • This is a civil community — be respectful.
  • No claims about other users.
  • Have fun!

Is it cool to click “agree” or “disagree” on my own claims?

We think so… check out our on-going argument about this.

Divide big ideas into multiple bite-sized claims

Make it easy for everyone to agree with the agreeable parts of your argument, and zero in on the juicy stuff — the places where there’s conflict. Plus, your argument score will grow higher faster with many short claims than it would with a few bloated ones.

Be Specific

Make sure everyone knows what you mean.

Use simple words

Only use big words when shorter synonyms don’t exist.

Be Concise

Life is short.

Write claims so they can be re-used in multiple arguments (when you can)

Certain fundamental claims contribute to many big ideas. If your claim is written to "stand alone" — i.e. it doesn't require the context of other claims to be understood — then other users can link to it in their own arguments.

Contest semantics only when a user's intent is truly unclear

When a grammatical error or hasty word choice prevents a clear interpretation of a user’s intent, use the Meta section to iron it out. But if the intent of a claim can be understood by a reasonable person, there's no need to call in the semantics police.


What's up with with dinosaurs?

Dinosaurs are awesome.

Who made Whysaurus?

Whysaurus was founded by Joshua Frankel, an artist and designer, and Aaron Lifshin, a software engineer.

I’ve got an idea that could make Whysaurus better, how can I share it with you?
