Where this framework comes from
The quiz on this site is an original, informal reflection game. It is inspired by empathizing–systemizing (E–S) theory, developed by Simon Baron-Cohen and colleagues. It is not the Empathy Quotient (EQ), not the Systemizing Quotient (SQ or SQ-R), and it is not a diagnostic instrument.
E–S theory is a research model of cognitive style. Autism is diagnosed clinically, not by an EQ/SQ score or by this quiz.
Core theory
Empathizing is the drive to identify another person’s mental state and respond with an appropriate emotion. Systemizing is the drive to analyze or build rule-based systems — mechanical, abstract, natural, or social. E–S theory treats these as two dimensions. An extension, the extreme male brain (EMB) theory, asks whether autistic people, on average, show a shift toward lower empathizing and equal or higher systemizing.

The questionnaires this quiz is not
The validated instruments are longer, use a different scoring rule (usually 2 / 1 / 0, with reverse-keyed items), and were built for research. Official “brain types” (Type E, Type S, Type B, Extreme E, Extreme S) come from the discrepancy between standardized EQ and SQ scores, not from a 3×3 high/medium/low grid.

Large-sample test
Greenberg, D. M., Warrier, V., Allison, C., & Baron-Cohen, S. (2018). Testing the Empathizing–Systemizing theory of sex differences and the Extreme Male Brain theory of autism in half a million people.
Proceedings of the National Academy of Sciences, 115(48), 12152–12157.
That study reported that D-scores (the difference between empathizing and systemizing) accounted for much more variance in autistic traits than demographic variables including sex. It is a research finding about group averages, not a rule for classifying an individual.
Clinical limits
The EQ and SQ are self-report research scales. They are not diagnostic tests for autism, empathy disorders, or any clinical condition. Diagnosis, when it is needed, is a clinical process using history, observation, and validated diagnostic tools.
This site’s 32-item game uses original wording, a 0–3 agree/disagree scale, and a nine-cell people × systems grid. Those choices are for a short public reflection, not for reproducing published cut-offs.
Critiques worth reading
E–S and EMB have been challenged on sex-difference claims, questionnaire structure, and the risk of treating “male brain / female brain” language as more than a psychometric shorthand.
