For example, anthropologist Douglas Fry (2005) looked through the literature in his field to inquire after the basic question: Which societies operate without war or with very rare examples of war? What he found was a welter of answers, but most of them were to slightly or even completely different questions, yet those studies were often cited as 'proof' that most, or even all, human societies are warlike and the few that weren't either were still violent or not worth mentioning.
But upon examining those cited studies, he found problems and this should encourage all of us to go deeper when we are citing any report or study--or when one is cited that seems to 'prove' that peace and justice are either a poor idea or impossible to achieve.

Whether we are using the best science to make our point or whether we are reading someone else's use of 'evidence,' we should be aware of the limitations of all research, in addition to the value of it.
