A new study finds that individuals who are open to new ideas and recognize both the strengths of others and their own limitations, have not succumbed to political apathy or indifference. The study also suggests these intellectually humble individuals are better able to seek accurate information rather than reflexively defend their own beliefs, and to pursue discussions on critical issues with an attitude of mutual respect.

The U.S. may be no different.
