Abstract
Individuals in social groups can gain benefits from being in those groups, including an increased ability to find food and avoid predators. We tested for potential group benefits in shelter choice in the Argentinian wood roach, Blaptica dubia. Roaches were tested in arenas with two shelters available in which one shelter was significantly darker than the other. Female and male roaches, housed separately, were tested as solitary individuals, or in same-sex groups of 5, 10, or 15. The roaches were tested under two light regimes (lights on vs. lights off) and two shelter distances (shelters near vs. shelters far) to provide variation in shelter search conditions. Solitary individuals chose the darker shelter at chance levels, but the roaches in groups chose the darker shelter significantly more often than chance. Furthermore, the two largest groups chose the darker shelter more often than the group of five roaches. We detected effects related to light variation that indicated roaches were more likely to be under either shelter in the lights-on conditions, and more likely to be out in the arena and under no shelter in the lights-off condition. Shelter distances had negligible effects on shelter choice and sex had no effect. Taken together, our results indicate individuals can make more optimal choices regarding shelter darkness if they are in a group, and that decision-making related to shelter is sensitive to variation in social context.

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 it
