Physiological condition improved in social groups with diverse personalities. Relationships between the Shannon index of group-level personality diversity of house sparrows and individual responses to social treatment in terms of (a) body condition (SMI) and (b) oxidative damage to lipids (MDA). Open symbols and dashed lines denote the pre-treatment sampling, while the filled symbols and continuous lines denote the post-treatment sampling. Regression lines are model-predicted slopes with 95% confidence intervals (shaded areas). Dots of the same exploration diversity value are jittered to decrease their overlap.
