Anathema Series

IQMean · Anathema Series

Anathema Tests

The Anathema series is built as a linked set of high-difficulty reasoning exams. Each part isolates a cognitive system—formal verbal logic, reading-driven inference, spatial transformation, and numerical pattern control—then the Apex test combines them into one mixed challenge.

Rules enforced on IQMean

  • Account required to take a test.
  • One attempt plus one retake. Final raw score is the higher of the two.
  • Correct answers are never revealed.
  • Each question uses A–J choices to reduce guess advantage.
  • IQ values appear after enough recorded scores exist for that test.

Recommended order

  • Part 1 establishes baseline logic accuracy.
  • Part 2 adds reading load and “must vs supported” traps.
  • Part 3 pressure-tests spatial state tracking.
  • Part 4 rewards disciplined rule discovery in sequences.
  • Part 5 is the synthesis: stamina and precision across domains.

Anathema Part 1 · Verbal

Hard

Formal logic traps: quantifiers, conditionals, “only if / unless,” and constrained deduction.

Domain: LogicBest for: baseline precision
Open Part 1

Anathema Part 2 · Verbal

Very Hard

Three reading sections with forced-inference questions, then relationship reasoning that punishes semantic drift.

Domain: InferenceBest for: rule tracking under narrative load
Open Part 2

Anathema Part 3 · Spatial

Very Hard

Cube nets, rotations, surface paths, drilling, and verbal visualization that still yields numeric certainty.

Domain: 3DBest for: mental rotation and transforms
Open Part 3

Anathema Part 4 · Numerical Patterns

Very Hard

Pattern compression: alternating generators, hidden recurrences, row/column transforms, and machines.

Domain: PatternsBest for: disciplined rule discovery
Open Part 4

Anathema Part 5 · Apex

Apex

Mixed reasoning under switching pressure: verbal logic, procedural reading, spatial tasks, visualization, and compact sequences.

Domain: MixedBest for: stability across domains
Open Part 5

Difficulty overview

TestGradePrimary skillsTypical failure mode
Part 1 · VerbalHardFormal logic, contradiction control, precise conditionalsAssuming “sounds right” equals “forced by rules”
Part 2 · VerbalVery HardInference under narrative load, must vs supported separationReading for vibe instead of structure
Part 3 · SpatialVery Hard3D state tracking, transforms, surface mappingOne early rotation error cascades into confidence errors
Part 4 · NumericalVery HardGenerators, invariants, multi-rule switchingOverfitting a rule that does not explain all terms
Part 5 · ApexApexPrecision under switching, stamina across domainsLosing internal rules when the question type changes
The series is designed for repeatable measurement and long-term stability. Raw scores are recorded immediately, while IQ mappings mature as datasets grow.
