Questions & answersPurpose, scores, evidence and corrections
What is Slugfester for?

Slugfester helps readers examine the reasoning in public debates. Scorecards bring arguments, replies, critiques and source passages together so you can inspect an exchange, compare assessments and decide where a case needs more support. The project also explores how well artificial intelligence (AI) can perform this work. Its value rests on the usefulness and accuracy of the analysis.

Why use AI?

AI makes detailed, structured analysis across many debates practical. It can help identify overlooked replies, compare reasoning and suggest stronger arguments for either side. Readers can assess those contributions on their merits without endorsing AI in general. AI authorship alone neither establishes nor refutes a conclusion; Slugfester remains responsible for what it publishes.

What does a score mean?

A score estimates the quality of the reasoning presented under the assessment criteria. It considers support, logical coherence, responsiveness and related features explained in the assessment guide. An 80/100 score is not an 80% probability that the speaker is right. Seeking truth is the aim; scores help direct attention to the arguments and evidence. They do not settle a worldview or measure a person’s worth.

What evidence is there that the assessments are accurate?

The linked recordings let readers check whether quotations, summaries and critiques fit the actual exchange. Another encouraging sign is visible in an interlocutor’s score graph: when their scores cluster within a narrow range across several debates, the assessments repeatedly place their debating competence at a similar level.

Under the standard blind-review workflow, the reviewers are independent AI agents called by the administrative AI. They do not receive earlier scorecards or published results, so those scores are not supplied as targets. Earlier assessments may use different controls.

This consistency supports confidence that the assessments are identifying a recurring pattern in the person’s performance. Accuracy still depends on how well the assessments represent and evaluate the actual arguments; a consistent bias or misunderstanding can also recur.

What does a tight cluster of one person’s scores show?

It shows that the person was assessed as demonstrating a similar level of debating competence across those debates. On an interlocutor’s profile, the score graph groups their debate scores into five-point ranges. Taller bars mean more debates received scores in that range. When most scores sit in a few neighboring ranges, you can see the consistency at a glance.

For example, Tom Jump’s 6 published one-on-one scores are 74, 76, 78, 78, 80 and 80 out of 100. They span 6 points. That cluster indicates broadly similar assessed performance across these debates.

Tom Jump · 6 debatesOverall score / 100 · bar height counts debates

To examine another person, select their name on the rankings page and look at their score distribution and debate list. Read the cluster alongside the number of debates, topics and opponents. It describes their assessed performance in those debates; it does not establish identical ability in every setting or guarantee that each judgment is correct.

How much weight should I give rankings and small score differences?

Read an average alongside the number of debates, their topics, the opponents and the assessment procedures. The catalogue is curated, and speakers face different conditions. Repeated differences across several debates are more informative than one result; neighboring averages can be too close to support a confident ordering. The ranking study explains both the stable patterns and the uncertainty about exact places. A one-point lead by itself does not establish a reliable advantage.

Can an assessment misunderstand an argument or reproduce bias?

Yes. A transcript can omit a qualification, a speaker can be misidentified, or an assessment can miss a reply or misread a disputed term. Separate AI reviews and fixed criteria help check these problems, but review agents using the same model can share a mistake. A detailed explanation makes a judgment easier to examine; it does not guarantee that judgment is correct.

Did the participants say everything shown on their scorecards?

Distinguish the quoted source passages, the site’s summaries and critiques, and the explicitly labeled AI contributions. A steelman is a strengthened version of an argument; it can add reasoning the participant did not supply. These proposed improvements and new ideas are separate from the recorded performance and do not contribute to participant scores. An accurate account of the original argument is still essential.

Can I inspect the prompts and instructions behind an assessment?

The guide below explains the standard workflow, and scorecards provide source links and assessment notes. A model’s name alone does not specify the instructions or evidence it received. Exact prompts and complete run records are not currently presented as a download for each debate. Use Feedback to identify the assessment and the materials you want to inspect. The current guide should not be assumed to describe every historical assessment.

What if an assessment misrepresents me or contains another error?

Use the scorecard’s “Report a possible scorecard issue” link, or the Feedback form. Identify the page and disputed wording, explain the problem, and include the relevant source passage or timestamp where possible. You do not need to diagnose the AI or propose a replacement score. A specific objection can be valid regardless of whether its author likes the result. Errors may not be corrected immediately, and submission does not guarantee a reply or a change to the current scorecard.

How can I contribute to the improvement of the scoring method?

Suggest an improvement to the choice of arguments, scoring criteria, weights or assumptions, and explain how it would improve the assessment. A methodological objection can matter across many debates, even when no quotation is wrong. You can also explore alternative scoring weights using the saved assessments.

Errors identified may not be corrected immediately. All feedback will be considered, but only complaints judged valid will be incorporated into the prompts used for future reevaluations of the entire debate corpus. Valid complaints will be generalized into review instructions and safeguards that apply to every assessment and score. The reviewers are independent AI agents called by the administrative AI. They will be asked to check for the underlying problem across all debates, so a valid complaint about one case can improve the process throughout the collection.

Will the debates be reassessed as AI improves?

A site-wide reassessment is tentatively planned for spring 2027, subject to stronger AI agents being available. A newer model still needs to demonstrate better performance. Future improvements do not establish the accuracy of today’s assessments, and specific errors can be reported now.

The administrative AI coordinates the process and calls independent AI agents to review the evidence and resolve disagreements. Throughout this guide and its diagrams, reviewers and adjudicators are those AI agents.

Controlled inputs, not perfect objectivity. Reviews by independent artificial-intelligence (AI) agents called by the administrative AI reduce avoidable influence, but shared model biases and mistaken judgments can remain. Selection is curated, not a representative sample of all debates.

  1. Define the debate

    Check for duplicates and identify the recording, speakers, event year, and a neutral central question. Record what each side must establish: its burden. A critic need not prove an alternative unless that burden is adopted. A duplicate recording is not silently reassessed.

  2. Secure the complete source

    Check transcript coverage, material gaps, and speaker changes against the full substantive debate. Use complete captions; transcribe if needed. A complete automatic caption track may be preferable to an incomplete human-written one. Preserve timestamps, acquisition information, and digital fingerprints that reveal later changes. Freeze the evidence, assessment rules, model settings, permitted repairs, and cost limits before judgment.

  3. Map the arguments, then lock the evidence

    Identify important claims, replies, concessions, and unanswered objections. Tie each selected move—a substantive argumentative contribution—to an exact source passage, speaker, topic, and relevant burden or reply. Section weights total 100%; move importance is 1, 2, or 3. Freeze both before scoring. Explain unequal coverage; never invent symmetry or drop arguments merely to fit the display.

  4. Two isolated AI reviews

    The administrative AI calls two independent AI agents. Both review the same locked evidence and rate every selected move, with reasons. Neither sees the other’s judgments, previous scorecards, published commentary, winner labels, or AI-added arguments. “Independent” means separate AI contexts with controlled inputs, not necessarily different models or model providers.

  5. Resolve differences

    Check audio whenever speaker attribution is below high confidence. Fixed rules flag dimension differences greater than 8 points, move-score differences greater than 4 points, adjustment differences greater than 2 points, and relevant categorical differences. The administrative AI calls a fresh independent AI agent to resolve disagreements—the adjudicator. This agent reviews the disputed evidence and anonymous options, without the review agents’ identities or calculated overall totals. Use the selected option for disputed ratings and rounded means for undisputed numerical ratings. Preserve both original reviews, the resolutions, and audio evidence, then freeze the resolved record.

  6. Calculate the scores once

    Six fixed dimensions determine each move’s score:

    • 25% logical coherence: Does the conclusion follow from the premises?
    • 20% evidence and warrant: Are the evidence and its connection to the conclusion adequate?
    • 20% responsiveness: Does the move answer the actual live challenge?
    • 15% relevance and burden: Does it advance or challenge what must be established?
    • 10% precision and clarity: Are terms, scope, and qualifications clear?
    • 10% calibration and charity: Is confidence proportionate, and is the opposing argument represented fairly?

    Move: round the weighted sum of the six ratings. Section, for each side: multiply each move score by its previously locked importance, add these results, divide by the total importance, and round. Overall, for each side: combine section scores using their prelocked percentage weights, add the burden-completion adjustment, then round and keep within 0–100.

    The default final adjustment is zero. An integer from −5 to +5 is allowed only for consequential full-debate burden completion not already counted in the moves. It cannot reward style or penalize the same defect twice. Models supply judgments; software calculates totals. No person hand-adjusts the result.

    Two separate worked examples—not actual debate results: moves scoring 80 and 70 with importance 2 and 1 produce (80 × 2 + 70 × 1) ÷ 3 = 76.67, rounded to 77. Sections scoring 80 and 70 with weights 60% and 40%, plus a +2 adjustment, produce 48 + 28 + 2 = 78. The first example’s 77 is not an input to the second.

    Stability checks: compare the final result with both original passes. Mean absolute distance is limited to 4 points, maximum distance from either pass to 8, and excursion beyond their range to 3. If both initial integer-rounded results favor the same side, the final result may favor that side or tie, but cannot reverse the winner. A failed check blocks acceptance; it is not permission to tune scores.

  7. Explain the locked result

    Publish every selected move exactly once. Quotations must match the eligible source wording and timestamps must lead to the relevant passage. Each critique explains the strongest feature, principal limitation, remaining burden, and locked score. Overall commentary identifies concrete strengths and material blunders for both sides. Explanations cannot change the selected moves, resolved judgments, or calculated totals.

  8. Review fallacies and cognitive biases separately

    After scores and critiques are locked, the administrative AI calls two fresh independent AI agents to examine every selected move against the local LogFall and CogBias definitions. Neither sees existing labels or the other agent’s review. The administrative AI then calls a fresh independent AI adjudicator to decide every candidate raised by either review agent, including candidates raised by only one.

    A label must identify a material defect supported by the complete source and already reflected in the critique. A contested premise is not automatically circular reasoning; a weak analogy is not automatically equivocation; citing an expert is not automatically an appeal-to-authority fallacy. Distinct labels require distinct failures. When uncertain, omit the label.

    Labels never add another numerical penalty. Finding no applicable labels is valid. Comparisons with earlier debates check consistency, not a target number of tags. Accepted labels link to local definitions and debate-specific explanations, with external LogFall or CogBias links for further reading.

  9. Keep AI contributions separate

    Clearly label strengthened arguments and genuinely new ideas for both sides as AI contributions. They are not transcript statements, are not attributed to the speakers, and never affect participant scores. Check their source-specific reasoning, added value, and repetitive wording. Biographical research also stays outside judgment packets and score calculations.

  10. Verify before publication

    Check source fingerprints, the score calculation chain, exact quotations, move coverage, label decisions, and the audit record. Compare explanation depth and specificity with 25 earlier debates without targeting their scores, argument counts, or tag rates. Test desktop and mobile pages, keyboard access, expandable sections, overflow, and links. Preserve rejected outputs and allow only bounded repairs that cannot rewrite locked scoring substance. Required checks must pass before publication, and the published result is then verified.

Team debates and scope limits

The ordinary workflow assesses one substantive advocate per side. A narrowly defined exception permits incidental host advocacy only when the recording is organized around two primary opponents, non-primary advocacy occupies at most 5% of the assessed window and adds no unique load-bearing argument, and excluded interventions and directly dependent replies are frozen and disclosed before judgment. Neither primary side receives credit or penalty for excluded material.

Panels and roundtables are not silently forced into that route. Authorized, stable two-team debates use a separate, disclosed approximation method. The team is the scoring unit: no individual score is inferred. Moves and labels retain their actual speaker attribution. Team and panel scores are excluded from individual rankings, profile averages, score distributions, and opponent records. Team checks include audio verification and tests of whether the leading side changes when contributions are rebalanced or one teammate is removed.

What scores mean: an estimate of argumentative performance in this debate, not the truth of a worldview, a speaker’s overall expertise, or a person’s worth. Fame, applause, accent, and speaking polish earn no automatic bonus. A true claim can be defended badly, and a false claim argued carefully. These safeguards improve consistency and traceability, not perfect objectivity.

Even a true statement may not advance that task. Asking the opponent to disprove a claim does not establish it.Precision & clarityAre important terms, claims, and qualifications clear and used consistently? Readers should be able to tell exactly what is being claimed, including its scope and limits.Calibration & charityDoes the speaker’s confidence match the available support, and is the opposing view represented fairly?

Debate 01 · Alex O'Connor

Suffering bears directly on Christianity because its saving, personally concerned God differs importantly from an indifferent first cause that permits suffering without intervention.

Read the chart correctly

What this snapshot measures

Positions, not personal identities

Supporting and challenging refer to the religious claim at issue in each debate. They are assigned from the published positions, not from the stored PRO/CON columns or a speaker’s personal beliefs. Challenging a claim need not assert that no God exists. A creator-only argument does not establish a personal, intervening God.

Descriptive argument families

Families use explicit word and phrase rules applied to the assessed move and its identifier, with the section title as a fallback. A move can appear in several families; percentages therefore need not add to 100. These are browsing labels, not a fresh philosophical assessment. “Other / general” retains unmatched material.

Each debate gets equal weight

Score charts first average the unique assessed moves within each debate, position, family, and selected role. The score-range chart shows the median and middle half of those debate averages, not confidence intervals. The dimension grid averages each debate’s share below the selected score threshold (70 by default). Repeated speakers can still influence the sample; these figures do not establish statistical significance.

Saved assessments, limited sample

The snapshot includes 226 of 300 published debates available when it was built. It describes selected assessed moves, not every utterance or all public debates. Unclear position pairs, team approximations, and legacy panels without compatible argument-level records are excluded. Small samples are marked below five debates. Scores assess the reasoning presented, not whether God exists.

Classifications and exclusions

No cases awaiting AI classification review. All 74 exclusions have recorded decisions.

Constructive and reply groups can contain different debates. Their comparison does not measure an argument’s change after rebuttal. Concessions remain in the other charts but are omitted from the case/reply comparison.

Position assignments use the corrected September 1 research taxonomy where available, plus explicit AI reviews of previously omitted panels and later debates. Legacy grouped scores without compatible argument-level records remain excluded. Scope follows the main debate topic, with explicit editorial corrections. Individual arguments can address related questions within that debate.

Calibration concerns whether the strength of a claim matches its support; charity concerns fair representation of an opponent. Relevance and burden concerns contact with the question a side needs to establish.
