Behavioral syndromes predict that individuals display behaviors consistently across different ecological situations, resulting in correlations among functionally different individual-specific behaviors (e.g., activity, exploration, aggression, and risk taking). Such consistencies can arise because of the common innate government of traits (i.e., temperament). However, different behaviors can be mediated by different selection regimes and/or measured with different errors. Furthermore, contextual overlap among traits may also vary. These possibilities can cause dissimilarities in the pair-wise relationship between particular traits. To determine the relationships among the most studied behaviors, we performed a modern meta-analysis, in which we assessed the strength of correlations in each possible combination of traits. Relying on data from 81 scientific papers, we found that the correlations among behaviors were …
