Feasible Alternative Comparator Calibration

Judge real options against reachable alternatives, not against perfection.

This candidate was drafted from queue position 45: nirvana_fallacy. It should be reviewed as a bounded fallacy-correction and option-evaluation archetype, not as a generic counterfactual reasoning entry.

Drafting note

The accepted catalog already contains general counterfactual comparison, experimental control-condition specification, and cost-benefit analysis. This draft fills the more specific gap exposed by the target prime: a real option should not be rejected because it fails against an infeasible ideal; the decisive comparison must be against the best feasible alternative under shared constraints.

Use this draft if the catalog wants direct coverage for nirvana-fallacy correction as a transferable decision discipline. Merge it into minimal_change_counterfactual_construction only if final reconciliation decides that feasible-comparator calibration should remain a subordinate counterfactual-construction variant.

Compression statement

Feasible-alternative comparator calibration prevents nirvana-fallacy reasoning by forcing option evaluation to identify the real choice set, exclude idealized or infeasible counterfactual comparators, select the best feasible alternative as the operative baseline, and report residual shortcomings as tradeoffs rather than as decisive disqualifications.

Canonical formula: valid_rejection(option) ⇔ ∃ feasible_alternative with expected_net_value > option; not merely ∃ ideal_counterfactual with value > option

Built directly on (5)

  • Comparative Method: Systematically juxtaposing selected cases so that their similarities and differences do the causal-inference work that controlled experiments cannot.
  • Cost–Benefit Analysis: Evaluate decisions.
  • Counterfactuals: Alternate hypothetical scenarios.
  • Informal Fallacy: A named, recurring pattern of defective argument whose error lies not in logical form but in content, context, or the relevance and acceptability of its premises — so it can be valid in form yet still fail as reasoning.
  • Nirvana Fallacy: Rejecting a real, available option because it falls short of an idealized counterfactual, when the operative comparison should be against the best feasible alternative.

  • Comparison: Place items in a shared frame along chosen dimensions to read off a relation between them.
  • Counterfactual Reasoning: Hypothetical alternatives.
  • Decision: Committing to one alternative from a set under uncertainty and trade-off, collapsing open deliberation into a chosen path and foreclosing the others.
  • Falsifiability: A claim is scientific only if it could in principle be empirically refuted.
  • Idealized-Substrate Fallacy: Designing against a friction-stripped idealized substrate, then deploying onto a real one where the elided terms dominate.
  • Joint vs. Separate Evaluation: The same option is ranked differently when evaluated alongside alternatives than when evaluated in isolation against an internal reference, because each evaluation mode makes a different subset of attributes evaluable and thus carries the verdict.
  • Minimal Modification Principle: Preserve true facts when constructing alternative scenarios.
  • Opportunity Cost: Value of best alternative.
  • Outcome-Defined Adequacy: Adequacy is specified by whether a defined outcome is produced in context, leaving the form open to any realization that achieves it.
  • Revealed Preference: Infer latent value from observed choices rather than stated reports.
