Building upon the work of Maoz and Russett, Bueno de Mesquita and Lalm
an, and Morgan and Campbell, the authors evaluate the ''democratic pea
ce'' phenomenon in an experimental setting. They first introduce the '
'political incentive'' explanation of why democracies don't fight each
other in the context of the diversionary theory of war, and then repo
rt results based on experiments with three groups of subjects: America
n students, nonstudent adults, and Israeli students. The results of al
l three experiments confirm the democratic peace findings and suggest
that democracies do not fight each other because their leaders have ve
ry few political incentives to do so.
