Judaism vs Spiritism: Faithscore Comparison

Overall scores

• Judaism — Faithscore 76/100 (Abrahamic Faith, 15 million followers)
• Spiritism — Faithscore 32/100 (Alternative Spirituality, 15 million followers)

Highest aggregate Faithscore: Judaism (76/100). The compared field spans 44 points across the same uniform rubric.

Comparative analysis

This comparison evaluates Judaism and Spiritism against the same six weighted evidentiary criteria — textual fidelity, historical verification, scientific testability, internal consistency, prophetic accuracy, and explanatory power — that Faithscore applies to all 313 systems in its registry. Aggregated across those criteria, Judaism receives the highest overall score (76/100), indicating strong overall support, with verified textual and historical foundations. Spiritism receives the lowest of the compared systems (32/100), indicating weak overall support across the weighted criteria. The arithmetic mean across the comparison is 54/100.

The 44-point spread is large enough that the ranking is unlikely to invert under reasonable methodological adjustments. The lower-scoring system has structural gaps in multiple criteria, not merely lower performance in one. Adherent counts are within an order of magnitude across the systems compared, so demographic weight is not a confounding factor in the comparison. The systems compared belong to different worldview categories, so the ranking should be read as a cross-category evaluation against a single uniform rubric — not as an artifact of category-specific assumptions.

It is important to note what this comparison does not claim. A higher Faithscore is not a metaphysical proof; it is a structured summary of how a system performs on six measurable axes the framework treats as evidentially relevant. Sincere adherents may reasonably weight criteria differently than this rubric does, and a low score on one criterion does not negate the explanatory or experiential value a tradition has for its community. The methodology is published in full and the per-criterion scores are reproducible from the cited source data, so any disagreement can be located precisely — at the rubric level, the criterion level, or the underlying evidence level.

Criterion-by-criterion breakdown

Each of the six weighted criteria, scored independently. The system with the higher score on each row is noted; aggregate ranking follows from the weighted total, not from a simple count of category wins.

• Textual fidelity — Judaism 80/100 vs Spiritism 22/100. Higher: Judaism. preservation, manuscript count, and accuracy of source documents
• Historical verification — Judaism 88/100 vs Spiritism 42/100. Higher: Judaism. independent corroboration, hostile-witness testimony, archaeological confirmation
• Scientific testability — Judaism 75/100 vs Spiritism 28/100. Higher: Judaism. falsifiable claims, observable evidence, repeatable predictions
• Internal consistency — Judaism 72/100 vs Spiritism 45/100. Higher: Judaism. logical coherence of doctrine and absence of contradiction
• Prophetic accuracy — Judaism 80/100 vs Spiritism 18/100. Higher: Judaism. ratio of fulfilled to unfulfilled predictions, dated against earliest manuscripts
• Explanatory power — Judaism 65/100 vs Spiritism 35/100. Higher: Judaism. how well the system accounts for the breadth of human experience
