Assessment & Research

Sex and discipline differences in empathising, systemising and autistic symptomatology: evidence from a student population.

Carroll et al. (2006) · Journal of autism and developmental disorders 2006
★ The Verdict

The original empathy and systemizing checklists can mislead if you treat them as precise rulers.

✓ Read this if BCBAs who use EQ or SQ in intake packets for teens or adults.
✗ Skip if Clinicians who only use the Autism-Spectrum Quotient or ADOS.

01Research in Context

01

What this study did

Galuska et al. (2006) gave college students two short checklists. One asked about empathy. The other asked about systemizing.

The team wanted to see if men and women scored differently. They also checked if high scores on one list matched high scores on the other.

02

What they found

Women rated themselves more empathic. Men rated themselves higher on systemizing. This part looked like past studies.

But the two checklists did not track together. A student could score high on both, low on both, or any mix. The tools did not behave as a single ruler.

03

How this fits with other research

Li et al. (2015) later tested Dutch versions of the same checklists. They found good reliability and clear factors. Their work supersedes the 2006 warning. The checklists can work when translated and refined.

Roane et al. (2001) had already shown the Autism-Spectrum Quotient cleanly splits groups. That success set the bar high. Galuska et al. (2006) showed the EQ and SQ are trickier to interpret in typical students.

Smees et al. (2025) carried the idea forward with children. They broke child empathy into four clear parts. This extends the line of work and shows the empathy piece can be saved with better items.

04

Why it matters

If you screen college-age clients for social programs, treat single EQ or SQ scores as rough notes, not verdicts. Pair them with direct skill probes like role-play or task analysis. Update your toolkit with the Dutch or child refinements when you need firmer numbers.

03Original abstract

Baron-Cohen's [(2002) Trends in Cognitive Sciences, 6, 248-255] 'extreme male brain' theory of autism is investigated by examining the relationships between theory of mind, central coherence, empathising, systemising and autistic-like symptomatology in typical undergraduates. There were sex differences in the expected directions on all tasks. Differences according to discipline were found only in central coherence. There was no evidence of an association between empathising and systemising. In the second study, performance on the Mechanical Reasoning task was compared with Systemising quotient and the Social Skills Inventory was compared with the Empathising Quotient. Moderate, but not high correlations were found. Findings are broadly consistent with the distinction between empathising and systemising but cast some doubt on the tasks used to measure these abilities.
