The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The analysis rests on ten survey items (K1–K7 on knowledge and information seeking; F1–F3 on interaction frequency), the single neurodiversity self-report filter that isolates single-condition groups, and Mann-Whitney U tests with Bonferroni-Holm correction. The paired sampling by work mode and experience is the mechanism that isolates the conditions under which differences appear.
What would settle it
Re-run the comparison using a clinically validated neurodiversity screening or diagnostic confirmation on the same sample; if the resulting effect sizes grow beyond small, or the ADHD K7/F2 differences appear in remote and in-person groups too, the paper's null-leaning conclusion is overturned.
Extended reading notes
Core claim
The paper's central claim is that employed neurodivergent software engineers do not differ substantively from neurotypical peers on the ten knowledge-sharing, interaction, and information-finding questions in the 2022 Stack Overflow survey. After correcting for multiple testing, only a handful of comparisons reach significance, and effect sizes are small (r between -0.07 and -0.22). The most consistent finding is for ADHD: these engineers report that waiting on answers disrupts their workflow (K7) and that they interact less with people outside their immediate team (F2), an effect that persists and sharpens in the hybrid-work subsample. For ASD, one unpaired comparison (K4) shows more difficulty finding answers with existing tools. The authors read these results as evidence that while ND professionals face real difficulties, they are not substantially different from NT professionals on these measures, and they caution that design features likely make the estimates conservative.
Load-bearing premise
The survey's one self-report question, after filtering out co-morbidities, correctly separates neurodivergent from neurotypical respondents; if many neurotypical respondents are undiagnosed neurodivergent, every comparison is biased toward no difference.
Editorial extensions
If this is right
- If the small-effect finding holds, workplace context and accommodations likely matter more than a neurotype label for day-to-day knowledge work.
- ADHD engineers in hybrid settings are the group most worth targeted support: reducing wait times for answers could cut workflow interruptions.
- The absence of differences in fully remote and full in-person comparisons means work mode should be a controlled variable in future neurodiversity-in-SE research.
- Future survey-based studies need validated diagnostic screening, not a single self-report item, to detect effects that this baseline could not.
Reading between the lines
- This editor infers that the study's restriction to employed engineers likely removes the most affected individuals; re-running with unemployed or underemployed ND developers could show larger effects than reported here.
- The K7 finding suggests a concrete, testable mechanism: for ADHD engineers, the latency of asynchronous question-answer channels is disproportionately disruptive; a tool-log study measuring interruption frequency around wait times could confirm it.
- The continent imbalance between ND and NT samples (ND respondents skewed European, ADHD respondents North American) may reflect diagnostic culture rather than workplace experience; matching by country could change which differences survive.
- Because the survey's Likert items are coarse, real differences could be masked; a purpose-built instrument with finer scales and direct measures of accommodation use is the natural next test.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper analyzes the 2022 Stack Overflow Developer Survey to compare professional software engineers with self-reported ASD (n=374), ADHD (n=1305), and dyslexia (n=363) against neurotypical engineers on ten questions concerning knowledge sharing, interaction, and information finding. The authors use Mann-Whitney U tests with Bonferroni-Holm correction applied across all tests within each condition, and they compare the groups under three sampling schemes: unpaired random samples, samples matched on work mode, and samples matched on years of work experience. The main finding is that few statistically significant differences emerge and the significant ones have small effect sizes, with the most consistent results being that ADHD engineers, particularly in hybrid work, report more workflow interruptions when waiting for answers (K7) and fewer interactions with people outside their team (F2). The paper interprets these results as a conservative baseline for future research and includes a detailed validity-threats discussion.
Significance. If the results are valid, this is a valuable large-scale quantitative complement to the mainly qualitative neurodiversity literature in software engineering. The study is unusually transparent: the filtered data and analysis scripts are available on Zenodo, the source data are public, and the statistical pipeline is clearly described. The ADHD-related differences in K7 and F2 replicate across the unpaired and hybrid-matched samples with corrected p-values below 0.01, providing a concrete, checkable result. The paper also deserves credit for an honest validity-threats section. However, the scientific value hinges critically on the clean separation of the neurotypical comparison group, because the headline result is an absence of differences; the manuscript's ambiguity on this point is the main concern.
major comments (3)
- [III-A1, V] The construction of the neurotypical comparison group is ambiguous and potentially load-bearing for the paper's null-leaning conclusions. Section III-A1 defines the NT group as 'no neurodiversity (none of the specified conditions)', while Section V-C states that the authors filtered 'people with mental health issues such as anxiety or depression' out of the ND groups, but nowhere states that the same exclusion was applied to the NT group. Since the survey recorded 'neurodiversity and/or any emotional or anxiety disorder' in a single question, a response of 'none of the specified conditions' may still include respondents with anxiety or depression. Such respondents would plausibly report more workflow interruptions and fewer social interactions, diluting any ND-NT differences and biasing the analysis toward the observed null results. The authors should clarify the exact survey item and their filtering code, and if anxiety/depression respondents are retained in the NT group, re-run all comparisons with an NT group that excludes every listed condition. In addition, Section V acknowledges 'undiagnosed conditions in our NT sample' but does not quantify this threat; a sensitivity analysis that estimates the robustness of the findings to plausible contamination rates would materially strengthen the claim.
- [IV-C, IV-D] The null results in several strata are difficult to interpret because per-stratum sample sizes are not reported and some are very small. Section III-A1 lists, for the work-mode strata, in-person groups of n=34 (dyslexia), n=133 (ADHD), and n=41 (ASD); with these sizes and a Bonferroni-Holm correction across multiple tests per condition, the Mann-Whitney U test has limited power to detect small effects. The paper's aggregate conclusion that 'we find only few significant differences' relies on these underpowered comparisons as much as on the well-powered unpaired and hybrid analyses. The authors should report the sample size for every comparison in the paper, provide a power analysis or the minimum detectable effect size for each stratum, and temper the conclusions accordingly when power is inadequate.
- [III-B, Tables I-III] The effect-size measure used in Tables I-III is not defined. The tables report values in parentheses and label them as 'small' or 'medium', but the manuscript does not state whether these are rank-biserial correlations, Z/sqrt(N), or another statistic, nor the thresholds used to classify them. Because the claim that the significant differences are 'small' is central to the paper's interpretation, the authors must define the measure, give the classification thresholds, and ideally report confidence intervals for the effect sizes.
minor comments (5)
- [III-A1, IV] The term 'paired sampling' is misleading: the authors frequency-match on work mode and work experience but still apply unpaired Mann-Whitney U tests; consider using 'matched sampling' throughout.
- [Abstract, IV-D1] The abstract and Section I say the observed effects are 'small', but Section IV-D1 reports a 'medium effect size' (-0.219) for K5 in the 0-5 years dyslexia stratum; harmonize this wording.
- [III-A1, V] Section V says the study 'included only employed and retired developers', but Section III-A1 restricts the sample to full-time employed respondents; clarify which population was actually analyzed.
- [IV-B] In the description of the significant ASD K4 finding, the direction of the effect is not tied to its sign; state explicitly that the negative effect size corresponds to lower agreement with being able to quickly find answers.
- [Tables I-III] The tables report corrected p-values of '1.00' for many non-significant comparisons; consider reporting the uncorrected p-values in an appendix so that readers can gauge the raw evidence.
Circularity Check
No significant circularity: the analysis is a secondary quantitative study of the externally collected 2022 Stack Overflow survey, and the few author self-citations are background only.
full rationale
The paper's central claim—that there are few significant differences between neurodivergent and neurotypical engineers on ten knowledge/interaction items—is obtained by applying Mann-Whitney U tests with Bonferroni-Holm correction to answers taken from the publicly available 2022 Stack Overflow Developer Survey. The ND and NT groups are defined by the survey's own self-report question plus explicit filtering (Section III-A1), and the outcome questions (K1-K7, F1-F3) are fixed survey items. Nothing in the statistical comparison is fitted to the authors' own definitions or to a prior result of theirs; the results are computed directly from the external dataset. The only author-overlapping citations, [4] and [7] (Liebel and Gama), appear in the related-work discussion and as qualitative context for why accommodations and environment matter; they are not the evidentiary basis for the K7/F2 findings. The acknowledged limitation about undiagnosed or undisclosed neurodivergent respondents in the NT group (Section V) is a construct-validity threat regarding who is in each comparison group, not a circular step: it does not make the reported differences equal to the paper's inputs by construction. Accordingly, no specific circular reduction can be quoted, and the appropriate finding is no significant circularity.
Assumptions & free parameters
assumptions (4)
- domain assumption The 2022 Stack Overflow survey's neurodiversity self-report question, combined with the authors' filtering to single-condition groups, correctly classifies respondents as neurodivergent or neurotypical.
- domain assumption Questions K1-K7 and F1-F3 validly measure knowledge sharing, interaction, and finding information at work.
- standard math Respondents are independent, satisfying the key assumption of the Mann-Whitney U test.
- domain assumption Pairing on work mode and years of work experience controls for the main confounding variables.

Neurodiversity describes variation in brain function among people, including common conditions such as Autism spectrum disorder (ASD), Attention deficit hyperactivity disorder (ADHD), and dyslexia. While Software Engineering (SE) literature has started to explore the experiences of neurodivergent software engineers, there is a lack of research that compares their challenges to those of neurotypical software engineers. To address this gap, we analyze existing data from the 2022 Stack Overflow Developer survey that collected data on neurodiversity. We quantitatively compare the answers of professional engineers with ASD (n=374), ADHD (n=1305), and dyslexia (n=363) with neurotypical engineers. Our findings indicate that neurodivergent engineers face more difficulties than neurotypical engineers. Specifically, engineers with ADHD report that they face more interruptions caused by waiting for answers, and that they less frequently interact with individuals outside their team. This study provides a baseline for future research comparing neurodivergent engineers with neurotypical ones. Several factors in the Stack Overflow survey and in our analysis are likely to lead to conservative estimates of the actual effects between neurodivergent and neurotypical engineers, e.g., the effects of the COVID-19 pandemic and our focus on employed professionals.
