Rahmat Wibowo posted that he ran his Verbal Fluency IQ pipeline on Indonesian social-media text from a named individual, publishing results estimating IQ 82 (below average) and mental age, framing the person's discourse as reactive and fragmented, weaponising pseudoscientific metrics to publicly degrade a named individual.

Transcript
ran my Verbal Fluency IQ pipeline on a real-
world sample of Indonesian social-media text
— and the results highlight both what the too!
does well and where it still needs work,
The numbers (340 words, Indonesian):
Verbal Fluency Score: 47.7 / 100
Estimated IQ: 82 (95% Cl: 75-89) — Below
Average
Mental Age: 24.6 (vs. chronological age 30)
Education estimate: Undergraduate ($1) —
medium confidence
What the data actually shows:
High lexical richness (MATTR 0.874, hapax
ratio 0.743) — the vocabulary variety is
genuinely strong. But low semantic
coherence (0.274) and high topic drift
(0.146) drag the overall score down. The
discourse is reactive and fragmented, which
the pipeline correctly flags as low-coherence
output regardless of vocabulary size.
Where the pipeline still has gaps:
Indonesian syntactic parsing is broken.
Dependency depth and subordination index
collapse to 0.0 for Indonesian text because
the spaCy xx_ent_wiki_sm model lacks a
proper dependency parser for the language.
This systematically deflates syntactic scores
—we need rule-based clause heuristics or an
Indonesian-specific model.
Language detection drops on code-switched
input. Heavy social-media abbreviation
mixed with English fragments lowered
detection confidence to 0.71. Worth building
a fallback layer for this.
The percentile output has a known bug — it
reports percentile 51 for 1@ 82, which should
map closer to the 12th percentile. The
interpolation logic in mapper.py needs a fix.
The tool is good at catching lexical
sophistication. It struggles with register
variation, noisy input, and Indonesian
morphology. Both are solvable — and
knowing exactly where it breaks is the first
step.
Building this iteratively. More case studies to
come.
