Abstract
Purpose This paper starts by considering what it means if dyslexia has genetic or environmental causes. The author also explains phrases used by genetic researchers and the kind of things they look for in genetic material. The purpose of this paper is to discuss two recent studies on dyslexia that shed light on either genetic or environmental causes. Design/methodology/approach One study was a thorough exploration of possible genetic differences that could be present in children experiencing reading and language difficulties. The other study examined a large sample of the Canadian public to see whether there was a link between dyslexia and having experienced physical abuse as a child or teenager. Findings The study on genetic differences found no evidence for some previously suggested genetic causes of dyslexia. Although previous studies have suggested dyslexia runs in families, the genetic contribution may have been overestimated. The study on the Canadian public found that people who reported experiencing physical abuse in their younger years were six to seven times more likely also to have a diagnosis of dyslexia. Childhood trauma is known to affect brain development. Originality/value Although this paper only discusses two papers in detail, they are two of the most recent explorations of genetic and environmental links to dyslexia. There could be a case for greater attention to possible traumatic experiences in children identified as dyslexic. Physical abuse is one possibility but should never be assumed. Families can be under strain and may need more support. However, dyslexia and the mental health difficulties that can result from childhood trauma can reduce a child’s current and future social inclusion. Early intervention may avert this outcome.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
