SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prevents the confirmation trap by forcing you to produce and evaluate serious alternative explanations for the same observations, so you can decide which hypothesis the evidence actually supports.

Core Features & Use Cases

  • Counter-hypothesis generation: Produces 3-5 genuinely different rival hypotheses (not straw men) such as reverse causation, common cause, selection bias, measurement artifacts, confounds, and base-rate/coincidence alternatives.
  • Evidence-fit assessment: Compares how well the original and each rival explain the cited observations and identifies what each would require to be true.
  • Discriminating evidence and decisive test: Determines what single observation would most cleanly rule hypotheses apart and proposes the most efficient investigation to narrow credibility.
  • Use cases: When you have a claim and want to stress-test it against skepticism (e.g., diagnosing why a metric changed, interpreting surprising events, evaluating causal explanations in research or decision-making, or steel-manning the most plausible alternative before acting).

Quick Start

Use the skill to generate 3-5 rival hypotheses for my claim and then identify the decisive test that would most efficiently discriminate between the best rival and my original hypothesis.

FAQPage Schema
Why does my causal explanation fit all the observations but still feel wrong?

Your causal reasoning has likely fallen into a confirmation trap where unexamined rival hypotheses fit the same observations equally well. Generating and testing alternative explanations prevents this by forcing you to evaluate which hypothesis the evidence actually supports.

How do I generate strong rival hypotheses to stress-test a causal claim?

To generate rival hypotheses for causal reasoning, you construct 3-5 genuinely different alternatives like reverse causation, common cause, or selection bias. You then assess how well each fits the cited observations and identify what each alternative requires to be true.

What is the best way to find discriminating evidence between competing hypotheses?

The best way to find discriminating evidence is to determine what single observation would most cleanly rule competing hypotheses apart. This requires a structured evidence-fit comparison followed by proposing the most efficient decisive investigation to narrow credibility.

Can I use this counter-hypothesis approach for diagnostic analysis of metric changes?

Yes, counter-hypothesis generation applies directly to diagnostic analysis when evaluating why a metric changed. It helps you steel-man the most plausible alternative explanations, such as measurement artifacts or base-rate coincidences, ensuring your diagnostic reasoning is robust before acting.

When do I need to test alternative explanations rather than just verifying my original claim?

You need to test alternative explanations during causal reasoning and hypothesis testing whenever rival explanations might fit equally well. Skeptical testing is essential for diagnosing surprising events or evaluating research claims to ensure you are not missing confounds or selection bias.

Does evaluating counter-hypotheses require any special statistical software or dependencies?

No, evaluating counter-hypotheses requires no special statistical software or external dependencies. The process relies on structured rival generation and evidence-fit comparison to identify discriminating evidence and propose a decisive investigation path.
