Public opinion is often difficult to determine, however, and people may hold contradictory views on some subjects. For example, almost everyone would say they want better health care, but they also would prefer that somebody else pay for it. People tend to oppose increases in taxes, but want to continue or expand government services to which they have become accustomed. Policy stalemate often reflects the inconsistency in public opinion, as different policymakers emphasize one or another of the public's apparent preferences and then argue over whose interpretation of the public's views is correct
