Abstract

fetched live from OpenAlex

Previous research has shown that same-sex sexual orientation is associated with differences in handedness. This study investigated this relationship by comparing Iranian cisgender gynephilic males (n = 239), cisgender ambiphilic males (n = 108), cisgender androphilic males (n = 314), transgender androphilic males (n = 103), cisgender androphilic females (n = 250), cisgender ambiphilic females (n = 96), cisgender gynephilic females (n = 32), and transgender gynephilic females (n = 123). Using a modified version of Edinburgh Handedness Inventory, we compared laterality index scores, rates of non-right-handedness, and extreme right-handedness between groups. Also, two features of handedness including its direction (i.e., the dominant hand) and strength (i.e., the degree of variability in preferring one hand over the other) were explored. We found that compared to gynephilic males, cisgender ambiphilic males had elevated non-right-handedness, and cisgender and transgender androphilic males had elevated extreme right-handedness. Our results indicated that right-handed cisgender androphilic males and females had greater strength compared to right-handed cisgender gynephilic males, while right-handed cisgender ambiphilic females and transgender gynephilic females had weaker strength compared to right-handed cisgender androphilic females. This study highlighted the importance of studying handedness direction and strength to understand underlying developmental factors influencing sexual orientation.

Teacher imitation

Not 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.
