Political scientist Dr. David Chen argues that democracies are less likely to fight each other than other regime pairings, a phenomenon known as the democratic peace theory.
Which statistical analysis would best support Chen's democratic peace claim?
Many countries are democracies
Wars have decreased since WWII
Analysis of all interstate conflicts since 1816 found zero wars between consolidated democracies, while democracy-autocracy and autocracy-autocracy pairs showed conflict rates of 3% and 5% respectively
International institutions promote peace
Correct Answer: C
Choice C is the best answer. Zero democracy-democracy wars vs positive rates for other pairings proves the pattern.
💡 Strategy: Claims about regime-type effects need comparison across all regime combinations.
