A new, sweeping CU Boulder analysis suggests birds of a feather are indeed more likely to flock together, confirming what individual studies have hinted at for decades.
• CU Boulder research has shown that opposites don't always attract.
• Analysis of more than 130 signs showed that partners most often resemble each other.
• Only 3% of signs indicate cooperation with those who are different from them.
• Research sheds light on the invisible forces that shape human relationships.
• The results may distort the results of genetic studies.
• A meta-analysis of 22 features across 199 studies showed a high correlation.
• Traits associated with substance use showed a high correlation.
• Height, weight, health status and personality traits showed a smaller but positive correlation.
