About

Structured debate is a way of cutting through disinformation and misunderstanding around complex topics. The key observation behind it is that policy decisions often depend on chains of logic that have gotten tangled or lost, and people forget or don't notice that key premises are basically wrong.

The mapper keeps track of the logical structure and shows what happens to the conclusion when a premise is found to be in error.

Need

A lot of political debate involves people reaching conclusions that involve fairly complex chains of reasoning -- they believe A because of B and C, and C because of D and E... and a lot of propaganda revolves around planting misinformation at those lower levels -- E is actually false, though everyone believes it, but the debate mostly revolves around A because nobody thinks to question C because that would require questioning D and E ...so people reach the wrong conclusion. Some of them may intuitively feel it's wrong, but they can't figure out why. There's a premise they're not checking.

So being "reasonable" ends up meaning you have to go along with a conclusion that's both factually and intuitively wrong.

Structured debate, and the debate mapper software, are designed to keep track of these complex relationships in order to reduce such errors from "inevitable" to "rare".

Ecosystem Features

Linking: In order to negate the need to replay existing debates within new contexts, any given point in a debate can be made dynamically dependent on the outcome of another debate.
Categorization: any given point within a debate may touch on one or more topics of general interest, and should be findable by anyone exploring that topic. A system for managing crowdsourced topic-tagging is under development.
Relationships: It may be useful to be able to quantify the nature of a link's relationship with more granularity. One possible relationship:
- A is a generalization of B (= B is a special case of A)
- A may be inferred from B (= B is a premise upon which A is based)
- Types of support-point (this will definitely be needed):
  - A is necessary in order for B to be true
  - A is sufficient in order for B to be true

Usability Features

Additional features not essential to the basic concept but which makes it more usable:

Text search: search within a branch for specific text or patterns
Notifications: users should be able to set a preference indicating that they do (or do not) want to be notified (by any of various methods) when any of the following occurs for any given debate point:
- the point's status changes (from true to false or vice-versa)
- anyone edits the point's text
- the status of any subpoint changes
- anyone adds a new support or counter point

There may be other usability features we will want to include.

Flaws

/counterpoint spam: Dishonest participants may repeatedly raise spurious objections solely for the purpose of keeping the correct conclusion in a state of presumed falsehood.

 ==About==
-[[Structured debate]] is a process for maximizing the [[rational debate|rationality of a debate]]. It assumes that the intent of debate is to determine the most likely truth when there is disagreement and that any party may be using invalid reasoning or incorrect facts. It relies on an ability to reliably reach consensus about whether reasoning is logical regardless of consensus on the conclusions.

-Structured debate provides a system for keeping track of the status of every point and counterpoint that has been raised in a debate. It allows multiple participants to make contributions simultaneously (which would not be possible in a spoken debate), permitting much more thorough fact-checking than in other forms of debate and ensuring that all positions have an opportunity to assert their objections to any given conclusion.

-===Validating Claims===
+===Need===
-In order to be [[rational]]ly defensible, any claim must be based on evidence plus reasoning. You can either agree with the conclusion, or you can dispute either the reasoning or the evidence. Faulty reasoning is pretty obvious once it's pointed out; faulty evidence is generally based on further evidence-plus-reasoning which may itself be agreeable or not.

Some of them may intuitively feel it's wrong, but they can't figure out why. There's a premise they're not checking.
-For any given conclusion, if you drill down deep enough you eventually find either:

-* bad reasoning -- a disputed conclusion is not valid; an undisputed conclusion may be true, but not for the reasons given
-* evidence that everyone can agree on (plus valid reasoning all the way up) -- the conclusion is valid

-==Details==
-===Terminology===
-# An '''[[issuepedia:argument|argument]]''' is a set of assertions that logically draw a conclusion from a set of premises.
-# Any argument is in a '''false state''' if either the logic or the premises are '''disputed'''.
-# Arguments disputing another argument is called a '''counterargument'''.
-# Any counterargument is itself an argument, and may be further disputed.
-# An argument is in a '''true state''' unless it is countered by one or more counterarguments which are themselves in a true state.
-See [[/rules]] for more detail.

-In theory, a structured debate can be held in an unstructured plaintext discussion environment such as Google+ or Facebook; rules and an example for doing this are [[/rules/plaintext|here]]. This format does require significantly more discipline from the participants, however.
+* [[/rules]]: structural design / "business" logic
-===Process===
+==Refinements==
-* Anyone may start a debate at any time; debate starts with an assertion of fact (the "prime assertion"), preferably defended by [[/supporting argument]]s.
-* Anyone may add [[/counter argument]]s or additional supporting arguments to this assertion at any time.
-* Each supporting or countering argument is itself an assertion, and may be further supported or countered at any time.
-* Debate continues indefinitely.
-** If new information is discovered which affects the debate, this information can be added immediately, with the potential to immediately change the debate's outcome (and hence the outcomes of any other debates which depend on this one, if others are linked to it; see [[#Ecosystem Features]]).
-** The design currently presumes that the final state of the prime assertion will eventually settle down to being true or false for long periods of time, as nobody will have any additional points to add; in practicality, decisions based on the debate's outcome will need to be made at specific times, and debates should be held in such a way that the final state will be likely to have settled down by the time any decision must be made.
-** There should probably also be a minimum amount of time between the last state-change and the actual decision, so as to negate the effects of last-minute [[/counterpoint spam]]ming.
-Individual debate venues may wish to make changes or additions to the procedural rules in order to accommodate their specific needs and circumstances.
