An important limitation of our study is that it focuses on the behaviors of children. The
advantage to doing so is that their social network is, in relation to adults, much more
clearly defined (their classmates). Nevertheless, we drew inferences from our data to
adult behaviors, though it would of course be valuable to conduct the studies with adult
populations necessary to confirm these inferences. Another limitation is that our study
does not establish a causal link between popularity and prosociality, nor did we intend to
do so. For example, it may be that people better at presenting themselves become
popular. Alternatively, popular people may experience greater pressure to perform pro-
socially in public, but then revert to behavioral patterns consistent with those of less
popular people when this pressure is absent. It would be especially profitable for future
research to address this issue.
