Finding truth: moving from opinion to judgment to justified belief

 Here is a concise, objective procedure—moving from opinion to judgment to justified belief—consistent with Objectivist epistemology and the primacy of reason and reality:

1. Observe and isolate the facts

• Begin at the perceptual level: identify the concrete existents involved and distinguish them from everything else. Name them precisely. Existence is the given; start there, not with feelings or wishes [1][4].

2. Define your terms and form the relevant concepts

• State explicit, objective definitions, identifying essential characteristics with measurement omitted. Purge equivocations and package-deals before you proceed; floating abstractions are not admissible evidence [3][4].

3. State a clear, testable proposition (a tentative opinion)

• Convert your initial idea into a specific claim about reality. A genuine “opinion” at this stage is a hypothesis tied to possible observation and logical implications; the arbitrary is neither true nor false and must be dismissed, not refuted [2][5].

4. Reduce the proposition to the perceptual level

• Trace every concept and step back to observable data: name the concrete referents, measurements, and operations that would verify or falsify the claim. No “stolen concepts,” no free-floating conclusions [1][6].

5. Gather all relevant evidence

• Seek positive and negative instances, measurements, and causal data. Include context: background conditions, methods, and potential confounders. Omit nothing you know to be relevant; knowledge is contextual [2][4].

6. Integrate the evidence by logic

• Apply identity, non-contradiction, and causality. Derive implications and check them against established knowledge, resolving clashes by identifying errors in definition, observation, or inference. A contradiction signals a mistake in premises or context, not in reality [1][3].

7. Identify causal mechanisms

• Do not stop at correlation. Specify what acts on what, by what means, under what conditions. Causality is a corollary of identity; explanation requires mechanism, not mere association [3][6].

8. Compare alternatives and eliminate the impossible

• Enumerate mutually exclusive possibilities. Reject those that contradict facts or require re-writing reality. Keep only those consistent with the full context of evidence and logic [2][4].

9. Apply the principle of the burden of proof

• Arbitrary assertions carry no cognitive weight and are to be dismissed. Only claims supported by evidence and reduction deserve consideration. This guards reason from invasion by the baseless [5][6].

10. Grade the evidential status: possible, probable, or certain

• Possible: some evidence, none contrary, but insufficient integration or data.
• Probable: the preponderance of evidence supports the claim, integrated with no unresolved contradictions.
• Certain: the evidence is conclusive within the total context; doubt would be arbitrary. Certainty is contextual, not infallible [1][2][4].

11. Issue a judgment (truth-status decision)

• Render a verdict on the proposition’s status (dismissed as arbitrary; possible; probable; certain). This is the evaluative conclusion reached by reason, not a report of how you “feel” about it [3][5].

12. Form a belief and act accordingly—context kept open

• When a claim is contextually certain, accept it as knowledge and guide action by it. Continue to integrate new evidence; if the context expands materially, update your judgment. Honesty requires loyalty to facts over prior commitments [2][6].

Quick audit checklist (to prevent error)

• Definitions: clear and consistent? No package-deals or equivocations? [4]
• Reduction: every step tied to perception? No floating abstractions or stolen concepts? [1]
• Logic: any contradictions left unresolved? Causal mechanism identified? [3]
• Context: have you included all relevant knowledge? Any context-dropping? [2]
• Evidence: is the claim arbitrary, possible, probable, or certain—and why? [5][6]

Summary: Opinion (hypothesis) becomes judgment (evidential status) only by reduction to facts and logical integration; belief (acceptance as true) is warranted when, in the full context, the evidence renders doubt arbitrary. Emotions are consequences of judgments, not tools of cognition; they play no role in validating truth. Reality is the standard; reason is the method [1][2][3][4][5][6].

Here is a concrete example, step by step, applying the procedure to a technical claim:

Claim to evaluate: “Coating X significantly extends the corrosion life of carbon steel in marine conditions.”

1. Observe and isolate the facts

• Identify the existents at issue: carbon steel panels exposed to salt-laden environments exhibit oxide formation (red rust) that weakens structural integrity over time. The measurable effects are time to first red rust, mass loss, pit depth, and coating breakdown. No feelings, no sales pitches—only what exists and can be observed and measured [1][4].

2. Define terms and concepts

• Define “extends” as “increases time-to-5%-red-rust” under a specified method (ASTM B117 salt-spray) and “significantly” as “≥50% increase relative to identical uncoated control panels” at equal dry-film thickness (DFT) control where relevant. Clarify the substrate (A36 steel), surface prep (SSPC-SP10), cure schedule, and exposure conditions. Eliminate equivocations like “better protection” without units or method; measurement is required, even if the specific numeric can be generalized across contexts afterward [3][4].

3. State a clear, testable proposition (tentative opinion)

• Proposition: “For A36 steel panels prepared to SSPC-SP10 and exposed to ASTM B117, Coating X increases median time to first 5% red rust by ≥50% versus uncoated panels.” This is a hypothesis tied to observation and potential falsification; it is not a floating “opinion” or a marketing assertion [2][5].

4. Reduce to the perceptual level

• Specify the concretes that would verify or falsify the claim: 30 coated panels vs 30 controls, identical geometry and surface roughness, randomized placement in the chamber, 5% NaCl fog at 35°C, periodic inspections, photographs, and mass measurements. Falsification would be equality or inferiority in median time-to-rust for Coating X relative to control under the same conditions [1][6].

5. Gather all relevant evidence

• Run a first lab test: control median time to 5% red rust = 220 hours; Coating X = 910 hours; 95% CI for improvement ratio ≈ 3.6±0.4; DFT held at 100±10 μm for all panels; cure verified by DSC and solvent rubs. Note a negative instance: one lot of Coating X failed early (~300 hours) due to improper oven cure; flag “cure quality” as a relevant condition. Replicate in a second lab: control = 240 hours; Coating X = 870 hours. Add electrochemical impedance spectroscopy (EIS): Coating X shows two orders of magnitude higher low-frequency impedance vs control (barrier effect). Document everything; omit nothing known to be relevant [2][4].

6. Integrate the evidence by logic

• The consistent multi-lab improvements, with DFT and environment controlled, support the claim. The outlier aligns with a discovered causal factor (cure deficiency), not a contradiction in reality. No valid evidence shows parity or inferiority when cure is proper. The integration yields a non-contradictory picture across tests and measures [3].

7. Identify the causal mechanism

• Microscopy and EDS indicate zinc-rich domains in Coating X that provide sacrificial galvanic protection at defects, while the polymer matrix yields a low-permeability barrier. Scribe tests show reduced undercutting near scratches, confirming the galvanic-plus-barrier mechanism. Causality flows from identity: a zinc-rich, well-cured barrier should reduce corrosion kinetics under chloride exposure; that is what is observed [3][6].

8. Compare alternatives and eliminate the impossible

• Alternative: “It’s just thicker.” Rebuttal: DFT matched; thickness cannot explain the difference. Alternative: “Chamber bias.” Rebuttal: randomized panel placement and cross-lab replication address that. Alternative: “Operator expectancy.” Rebuttal: blinded coding of panels. After eliminating these, the remaining explanation—Coating X’s mechanism under the stated conditions—stands consistent with the full context [2][4].

9. Apply the burden of proof

• Marketing claims like “nano-vibrational energy fields make steel happier” carry no evidence or reduction to observation; they are arbitrary and are dismissed, not refuted. Only reduced, evidenced claims count in cognition and decision-making [5][6].

10. Grade the evidential status

• Possible after the first run showing large improvement with no contrary evidence.
• Probable after replication across labs and methods (B117 plus EIS) showing the same direction and magnitude of effect.
• Contextually certain for the defined context (A36, proper cure, controlled NaCl fog at 35°C), since doubt would now be arbitrary relative to the integrated total of evidence and mechanism. For different contexts—UV-intensive outdoor exposure, freeze–thaw cycling—status remains probable pending field data, because UV may degrade the binder and alter long-term performance [1][2][4].

11. Issue a judgment (truth-status decision)

• Judgment: The proposition is true—contextually certain—for salt-spray marine simulation with proper cure and specified DFT; probable for outdoor marine exposure with UV; undetermined for acid rain and freeze–thaw until tested. The verdict is about facts, not feelings [3][5].

12. Form a belief and act—context kept open

• Accept as knowledge: “Under the specified conditions, Coating X extends corrosion life by well over 50%.” Act accordingly: specify Coating X for ballast tanks and enclosed, UV-protected marine environments; require cure verification in QA; and commission year-long outdoor exposure racks for UV/freeze–thaw before top-side approval. Remain vigilant: if outdoor racks later show rapid UV chalking and performance collapse, revise the belief and specification to match the expanded context. Loyalty is owed to facts, not to prior commitments [2][6].

Summary: We began with reality, defined our terms, formed a testable hypothesis, reduced it to observations, integrated the full body of evidence by logic, identified the causal mechanism, eliminated alternatives, graded the claim’s status, issued a precise judgment, and acted on contextually certain knowledge—ready to update if new, relevant facts emerge. Emotions and wishful thinking played no role; existence, logic, and evidence ruled the process [1][4].
