Wikidebate/Guidelines

This page contains some general guidelines about wikidebates.

Neutral point of view

Wikidebates are organized compilations of arguments surrounding an issue. Therefore, try to add and improve arguments on both sides of the issue. Being neutral or unbiased implies considering both sides and being open to change your mind if the arguments or evidence require it. You should be willing, almost eager, to change your mind, in order to judge opposite arguments more objectively. Who knows, you may even learn something.

Clarifying arguments on the opposite side also makes the weak points easier to spot.

The objective of a debate should be to establish truth when the issue at hand is a matter of fact, or facilitate compromise when there are conflicting interests, and not merely to practice rhetoric or promote a given issue (in other words, we should aim for dialectic rather than eristic).

Do not be afraid to debate with yourself! If you can think of an argument, an objection to it, and an objection to the objection, go ahead and add them all. Other readers may have the same concerns and will appreciate it.

Arguments belong to all

Unlike other debate systems, wikidebates are not aggregates of posts by different users, but a collaborative effort to compile and organize all arguments on an issue. Therefore:

• Don't sign your arguments ― Signing arguments discourages others from improving them. The original author can always be traced back from the history of the debate.
• Avoid pronouns ― Avoid words like, 'I', 'you', 'me', 'we', etc. No arguments are 'yours' or 'his'. There are no sides here, we're all working together, collaborating.
• Don't quote classic arguments verbatim ― Instead rewrite them in your own words (improving brevity, clarity and order, for example) and give credit to the original source or author using a reference or in the edit summary. When an argument is quoted directly, any improvements become distortions. But the point of a wiki is to be able to improve on the work of others. If there is a better way to present an argument, then respect for the original shouldn't be an obstacle. We're not trying to reach historical accuracy here.

Brevity, clarity and order

Wikidebates can easily become long and chaotic, making them less likely to be read and improved upon. Therefore, we should strive to keep them as brief, clear and organized as possible.

• Use footnotes ― If an argument relies on many premises, and each premise needs proof, don't include the proof inline. Instead, use footnotes to link to the works that prove your premise.
• Merge equivalent arguments ― If two arguments are essentially the same, merge them together into one, keeping the best of each.
• Split distinct arguments ― If one argument is essentially two, split them apart. Keeping them separate will enrich the debate, allow others to object to each argument independently and prevent unnecessary confusion.
• Keep it flat ― When a branch grows, it's often possible to reformulate an argument so that some objection doesn't apply anymore (example 1, example 2). If someone posts an objection pointing out a flaw in an argument, try to fix the flaw and remove the objection, rather than answering the objection or posting another argument without the flaw. For instance, if someone objects to an argument exploiting an ambiguity, don't object saying that what the argument "really" means is something different from what it says. Instead, rewrite or clarify the argument and remove the objection as no longer relevant. If, say, in the abortion debate, someone says "Abortion sometimes occurs naturally, and we shouldn't punish people for natural occurrences", then don't object saying "We meant induced abortion". Instead, clarify it in the debate description and remove the argument as being no longer relevant. This improves the overall quality of the debate while shortening its length and complexity.
• Define the key terms ― Sometimes people completely agree regarding the facts of the matter, but use different words to describe it, so they disagree nominally and delve into fruitless debate. For example, people may agree as to what computers can and can't do, but some may consider that being able to do certain things amounts to "intelligence", while the others do not. Thus, they will disagree as to whether computers are intelligent or not, but only because they don't agree in the use of the word "intelligence". So the debate is no longer about computers, but about words. If you recognize such a disagreement about words, try to define them in the description of the debate and then update or delete any misguided arguments.

How to argue effectively

The best way to argue is with sound arguments. An argument is sound when the premises:

• Are all true
• Imply the conclusion
• Don't assume what must be proved

If the best way to argue is with sound arguments, then the best way to object is with sound arguments showing that the target argument isn't sound. In other words, to object effectively, show that the premises of the target argument:

• Are not all true
• Don't imply the conclusion
• Assume what must be proved

Referring to the evidence is the best way to avoid objections requesting evidence. Refer to the evidence using footnotes to keep arguments brief, clear and concise.

How to draw conclusions

The methods described below only apply if you agree with the current status of all the arguments in the debate (but not necessarily of all the objections). If you don't agree with the status of some of the arguments, add your objections, reconsider your beliefs or don't use the methods described below.

There are two kinds of debates: debates about facts and debates about conventions. For example, Does God exist? is a debate about a fact, while Should abortion be legal? is a debate about a convention. The proper way of drawing conclusions is different for each kind of debate.

Debates about facts

In debates about facts, infer the option with at least one sustained argument for and none against, if every other option has no sustained arguments for.

Needless to say, the current results of the debates aren't necessarily right or wrong. It's impossible to know, for certain anyway, if the current result of a debate is the absolute truth. However, if one option has few arguments, all refuted with several objections, and another option has many arguments with few objections refuted in various ways, then there's good reason to believe the second option. If the state of the debate is clear enough, one may, and should, infer the conclusion, but there will always be a leap of faith somewhere, even if tiny. Absolute certainty can never be achieved. However, when all arguments and all objections have been considered, the result will be our best guess as to the truth of the issue at hand. This is the most humans can aim for, and we should aim for it.

Some key logical consequences are:

• The number of arguments doesn't matter ― There may be just one argument in favor and hundreds against, but if the argument in favor is sustained and the hundreds are refuted, the answer will be what the argument in favor supports. Wikidebates are not a popularity contest.
• Not all arguments for an option need to be sustained in order for that option to prevail ― Just one is required (and none on the other options). In fact, if an issue is truly controversial, it should even be expected that all options will have some refuted arguments.

In pseudocode:

function getBalance( option ) {
    balance = 0
    arguments = getArguments( option )
    for argument in arguments {
        balance = balance + weight( argument )
    }
    return balance
}

function getWinner( debate ) {
    if ( getBalance( option1 ) > 0 and getBalance( option2 ) < 1 ) {
        return option1
    }
    if ( getBalance( option1 ) < 1 and getBalance( option2 ) > 0 ) {
        return option2
    }
    // And similarly combining any extra option
    // Else return nothing
}

Debates about conventions

“ In the Affair of so much Importance to you, wherein you ask my Advice, I cannot for want of sufficient Premises, advise you what to determine, but if you please I will tell you how. When these difficult Cases occur, they are difficult chiefly because while we have them under Consideration all the Reasons pro and con are not present to the Mind at the same time; but sometimes one Set present themselves, and at other times another, the first being out of Sight. Hence the various Purposes or Inclinations that alternately prevail, and the Uncertainty that perplexes us. To get over this, my Way is, to divide half a Sheet of Paper by a Line into two Columns, writing over the one Pro, and over the other Con. Then during three or four Days Consideration I put down under the different Heads short Hints of the different Motives that at different Times occur to me for or against the Measure. When I have thus got them all together in one View, I endeavour to estimate their respective Weights; and where I find two, one on each side, that seem equal, I strike them both out: If I find a Reason pro equal to some two Reasons con, I strike out the three. If I judge some two Reasons con equal to some three Reasons pro, I strike out the five; and thus proceeding I find at length where the Ballance lies; and if after a Day or two of farther Consideration nothing new that is of Importance occurs on either side, I come to a Determination accordingly. And tho' the Weight of Reasons cannot be taken with the Precision of Algebraic Quantities, yet when each is thus considered separately and comparatively, and the whole lies before me, I think I can judge better, and am less likely to make a rash Step; and in fact I have found great Advantage from this kind of Equation, in what may be called Moral or Prudential Algebra. Wishing sincerely that you may determine for the best, I am ever, my dear Friend, Yours most affectionately, ” — Letter by Benjamin Franklin to Joseph Priestley, September 19, 1772

When debating conventions, use your best judgment to weight the sustained arguments on each side, but ignore the refuted ones.

Debating about conventions (among which we count laws) is different from debating about facts. When debating about facts, all arguments on the false side must ultimately be wrong, otherwise reality would be contradictory. By contrast, when debating about conventions, there may be sound arguments on all sides, and deciding becomes a matter of weighting the sound arguments on each side.

But what is the "weight" of an argument and how do we measure it? The weight of an argument is its importance and relevance to the debate. And how do we measure weight? There's no agreed method (so far). Each reader must use his or her best judgment to weight the arguments.

The balance of an option is the combined weight of the sustained arguments for it, minus the combined weight of the sustained arguments against it.

In debates about conventions, infer the option with the best balance.

This can be put in pseudocode thus:

function balance( option ) {
    balance = 0
    arguments = getArguments( option )
    for argument in arguments {
        balance = balance + weight( argument )
    }
    return balance
}

function winner( debate ) {
    if ( balance( option1 ) > balance( option2 ) ) {
        return option1
    }
    if ( balance( option1 ) < balance( option2 ) ) {
        return option2
    }
    // Else no winner
}
