Why <strong>Fuzzy</strong> <strong>Set</strong>s (fs<strong>QCA</strong>)?<br />
Social phenomena differ in kind and degree<br />
• Difference in kind: democracy versus<br />
authoritarian regime<br />
• Difference in degree: Norway vs. Italy (equally<br />
democratic?)<br />
fs<strong>QCA</strong> combines set-theoretic analysis with<br />
gradations in set membership<br />
• Crisp sets (0 or 1): differences in kind<br />
• <strong>Fuzzy</strong> sets (between 0 and 1): differences in kind and<br />
degree
