Posting arbitrary emojis doesn’t achieve that purpose.

Maybe it does. Any kind of reaction is a response that turns a criticism from ‘pending’1 to not ‘pending’ anymore.


  1. ‘Acknowledged’ vs ‘unacknowledged’ may be better terminology here, to avoid overlap with the current notion of pending criticisms.)

Agreed, thanks. Fixed in #4095. “Since decision-making follows the same logic as truth-seeking, you can use these trees to make decisions, too.”

How Does Veritula Work?

Veritula (Latin for ‘a bit of truth’) can help you live a life guided exclusively by reason.

To reason, within any well-defined epistemology, means to follow and apply that epistemology. Unreason, or whim, is an undue departure from it. Epistemology is the study of knowledge – basically, the study of what helps knowledge grow, what hinders its growth, and related questions.

Veritula follows, and helps you apply, Karl Popper’s epistemology, Critical Rationalism. It’s a continuation of the Athenian tradition of criticism and the only known epistemology without major flaws.1

Critical Rationalism says that ideas are assumed true until refuted. This approach leaves us free to make bold guesses and use the full arsenal at our disposal to criticize these guesses in order to solve problems, correct errors, and seek truth. It’s a creative and critical approach. Critical Rationalism is a fallibilist philosophy: there is no criterion of truth to determine with certainty whether some idea is true or false. We all make mistakes, and by an effort, we can correct them to get a little closer to the truth. Rejecting all forms of mysticism and the supernatural, Veritula recognizes that progress is both possible and desirable, and that rational means are the only way to make progress.

Veritula is a programmatic implementation of Popper’s epistemology.

Veritula provides an objective, partly automated way to tentatively determine whether a given idea is problematic. It does not tell you what to think – it teaches you how to think.

Consider an idea I:

plaintext
I

Since it has no criticisms, we tentatively consider I unproblematic. It is rational to adopt it and act in accordance with it. Conversely, it would be irrational to reject it, consider it problematic, or act counter to it. (See #2281 for more details on rational decision-making.)

Next, someone submits a criticism C1:

plaintext
I
|
C1

The idea I is now considered problematic so long as criticism C1 is not addressed. How do you address it? You can revise I so that C1 doesn’t apply anymore, which restores the previous state with just the standalone I (now called I2 to indicate the revision):

plaintext
Revise
I ------------> I2
|
C1

To track changes, Veritula offers beautiful diffing and version control for ideas.

If you cannot think of a way to revise I, you can counter-criticize C1, thereby neutralizing it with a new criticism, C2:

plaintext
I
|
C1
|
C2

Now, I is considered unproblematic again, since C1 is problematic and thus can’t be a decisive criticism anymore.

If you can think of neither a revision of I nor counter-criticism to C1, your only option is to accept that I has been (tentatively) defeated. You should therefore abandon it, which means: stop acting in accordance with it, considering it to be unproblematic, etc.

Since there can be many criticisms (which are also just ideas) and deeply nested counter-criticisms, the result is a tree structure. For example, as a discussion progresses, one of its trees might look like this:

plaintext
I
/ | \
C11 C12 C13
/ \ \
C21 C22 C23
/ \
C31 C32

In this tree, I is considered problematic. Although C11 has been neutralized by C21 and C22, C12 still needs to be addressed. In addition, C23 would have neutralized C13, but C31 and C32 make C23 problematic, so C13 makes I problematic as well.

You don’t need to keep track of these relationships manually. Veritula automatically marks ideas accordingly.

Since decision-making follows the same logic as truth-seeking, you can use these trees to make decisions, too. Veritula implements unanimous consent as defined by Taking Children Seriously, a parenting philosophy that builds on Popper’s epistemology. When you’re planning your next move but can’t decide on a city, say, Veritula helps you criticize your ideas and make a rational decision – meaning a decision you’ll be happy with. Again, it’s rational to act in accordance with ideas that have no pending criticisms.

All ideas, including criticisms, should be formulated as concisely as possible, and separate ideas should be submitted separately, even if they’re related. Otherwise, you run the risk of receiving ‘bulk’ criticisms, where a single criticism seems to apply to more content than it actually does.

Again, criticisms are also just ideas, so the same is true for criticisms. Submitting each criticism separately has the benefit of requiring the proponent of an idea to address each criticism individually, not in bulk. If he fails to address even a single criticism, the idea remains problematic and should be rejected.

The more you discuss a given topic, the deeper and wider the tree grows. Some criticisms can apply to multiple ideas in the tree, but that needs to be made explicit by submitting them repeatedly.

Comments that aren’t criticisms – eg follow-up questions or otherwise neutral comments – are considered ancillary ideas. Unlike criticisms, ancillary ideas do not invert their respective parents’ statuses. They are neutral.

One of the main benefits of Veritula is that the status of any idea in a discussion can be seen at a glance. If you are new to a much-discussed topic, adopt the displayed status of the ideas involved: if they are marked problematic, reject them; if they are not, adopt them.

Therefore, Veritula acts as a dictionary for ideas.

One of the problems of our age is that people have same discussions over and over again. Part of the reason is widespread irrationality, expressed in the unwillingness to change one’s mind; another is that it’s simply difficult to remember or know what’s true and what isn’t. Discussion trees can get complex, so people shouldn’t blindly trust their judgment of whether some idea is true or problematic, whether nested criticisms have been neutralized or not. Going off of memory is too error prone.

Veritula solves this problem: it makes discussion trees explicit so you don’t have to remember each idea and its relation to other ideas. Veritula therefore also enables you to hold irrational people accountable: if an idea has pending criticisms, the rational approach is to either abandon it or to save it by revising it or addressing all pending criticisms.

Many people don’t like to concede an argument. But with Veritula, no concessions are necessary. The site just shows you who’s right.

Using Veritula, we may discover a bit of truth.


  1. Popperian epistemology has some flaws, like verisimilitude, but Veritula doesn’t implement those.

Then people could occasionally check the search page for ideas they think they can rationally hold but actually can’t. And then they can work on addressing criticisms. A kind of ‘mental housekeeping’ to ensure they never accidentally accept problematic ideas as true.

#4084​·​Dennis HackethalOP revised 8 months ago​·​Original #2623​·​Criticized1Archived

That could be hard to verify.

#4079​·​Dennis Hackethal, 8 months ago​·​CriticismCriticized2

Another reason I want people to use their true names is that I want Veritula to be a place for serious intellectuals, not yet another social network where people just screw around. Part of being a serious intellectual is public advocacy of one’s ideas and public updates on changed positions.

#4076​·​Dennis Hackethal revised 8 months ago​·​Original #2455​·​CriticismCriticized1

When people use their true names, I expect higher quality contributions, less rudeness, fewer trolls, that kind of thing. More accountability generally means higher quality.

#4074​·​Dennis Hackethal revised 8 months ago​·​Original #2454​·​CriticismCriticized1

But that doesn’t address the part about public advocacy of one’s ideas and public updates on changed positions in the sense that you put your own name behind your ideas.

#4073​·​Dennis Hackethal, 8 months ago​·​CriticismCriticized3

Now that there are user profiles (#408), the search page can have an option to filter ideas by user. That way, we can see that user’s uncontroversial ideas, meaning ideas of his that he can rationally hold, and controversial ones, meaning ideas of his that he cannot rationally hold.

Some people (most notably Ella Hoeppner) have argued that replication isn’t necessary for evolution to take place. All you need is variation and selection.

How Do Bounties Work?

Bounties let you invite criticism and reward high-quality contributions with real money.

Bounties are in beta. Expect things to break.

How do I participate?

First, log in or sign up.

Next, browse the list of bounties. Click a bounty’s dollar amount to view its page, review the bountied idea and the terms, and submit a criticism on that idea.

That’s it – you’re in.

How do I get paid?

Each bounty enters a review period roughly five days after it starts (the exact date is shown on the bounty page). The review period lasts 24 hours. During this time, the bounty owner reviews submissions and rejects only those that don’t meet the stated terms.

To be eligible for a payout, all of the following must be true:

  1. Your submission is a direct criticism of the bountied idea.
  2. Your submission has no pending counter-criticisms when the review period begins.
  3. Your submission meets the bounty terms and the site-wide terms.
  4. You’ve connected a Stripe account in good standing before the review period ends.

The bounty owner is never eligible to receive payouts from their own bounty.

Note that counter-criticisms are not constrained by the bounty-specific terms. Only direct criticisms of the bountied idea are.

How much will I get paid?

The bounty amount is prorated among all eligible submissions.

For example, if there are ten eligible criticisms and you contributed two of them, you receive 20% of the bounty.

Fractions of cents are not paid out.

How do I run a bounty?

Click the megaphone button next to an idea (near bookmark, archive, etc.).

Set a bounty amount and write clear terms describing the kinds of criticisms you’re willing to pay for. Then enter your credit-card details to authorize the amount plus a 5% bounty fee.

Your card is authorized, not charged, when the bounty starts.

The bounty typically runs for five to seven days, depending on your card’s authorization window. Toward the end, a 24-hour review period begins. During this time, review submissions and reject those that don’t meet your terms. Submissions you don’t reject are automatically accepted at the end of the review period and become eligible for payout. Your card is then charged the full authorization.

If you reject all submissions, your card is never charged.

Can I fund an existing bounty?

Yes. Review the bounty terms. If you agree with them, click the ‘Add funding’ button on the bounty page and follow the next steps. At this point, your card is authorized but not charged.

If the bounty owner accepts any submissions during the review period, your card is charged the full authorization. If he rejects all submissions, your card is never charged.

Funders are never eligible to receive payouts from a bounty they funded.

Start a bounty today. Terms apply.

There needs to be more of a padding on the right, inside the code block.

Ayn Rand says one important part of living rationally in an irrational society is to pronounce judgment.

In short, if someone attacks your values, say something! Especially if silence could be mistaken as sanction of evil.

If you don’t pronounce judgment, both good and evil know they can’t expect anything from you. So by default, silence favors evil and betrays good. There’s no such thing as moral neutrality or ‘grayness’.

To pronounce judgment, you don’t need to be omniscient or infallible. But you do need integrity.

Many people are afraid of being judged. They like to say “Judge not, that ye be not judged.” They hope to get a moral blank check by writing one for others.

But the reality is that people have to make choices. To make choices, they need moral values. So moral neutrality hurts their ability to make choices. It’s also a slippery slope toward evasions. When people are morally ‘gray’, they say things like ‘no one is fully good or fully bad.’ That just helps evil along.

The moral principle people should adopt instead is: “Judge, and be prepared to be judged.

Judging means “evaluat[ing] a given concrete by reference to an abstract principle or standard.” It’s not easy and you can’t do it automatically through feelings. It requires deliberate, rational thought. It must be well-reasoned and can’t be arbitrary.

Judging does not mean going around offering your opinion unsolicited or saving others. It does mean two things: “(a) that one must know clearly, in full, verbally identified form, one’s own moral evaluation of every person, issue and event with which one deals, and act accordingly; (b) that one must make one’s moral evaluation known to others, when it is rationally appropriate to do so.”

Sometimes you can just say you disagree, other times you may need to state your views more fully. It depends on your interlocutor and on context.

Pronouncing judgment protects the clarity of your thoughts against society’s irrational background.

Ultimately, society is run either by “the man who is willing to assume the responsibility of asserting rational values” or by “the thug who is not troubled by questions of responsibility.”

So speak out when someone attacks your values.

Feature idea: pay people to criticize an idea.

You start a ‘criticism bounty’ of 100 bucks, say, which is prorated among eligible critics after some deadline.

The amount should be arbitrarily customizable (while covering transaction costs). Minimum of $5.

There could then be a page for bounties at /bounties. And a page listing a user’s bounties at /:username/bounties.

When starting a bounty, the user indicates terms such as what kinds of criticism they want. This way, they avoid having to pay people pointing out typos, say.

Anyone can start a bounty on any idea. There can only be one bounty per idea at a time.

To ensure a criticism is worthy of the bounty, the initiator gets a grace period of 24 hours at the end to review pending criticisms. Inaction automatically awards the bounty to all pending criticisms at the end of the grace period.

When I revise a criticism, I can’t see what it criticises. The edit screen should show the parent idea, similar to when I write a new criticism.

Should not autopair behind a word character.

Steps to reproduce:

  1. Type 'foo'.
  2. With the cursor behind the second 'o', hit single quote: '.
  3. The text now reads foo'' but should only read foo'.

After a non-word character (eg linebreak, period, colon, semicolon etc) though, it should still autopair.
