Is not an oxymoron. Happy is redundant.
Foxnews reports on a study funded by the (US) National Science Foundation and appearing in the June issue of the journal Pschological Science that found that:
"Individuals with conservative ideologies are happier than liberal-leaners, and new research pinpoints the reason: Conservatives rationalize social and economic inequalities.
"Regardless of marital status, income or church attendance, right-wing individuals reported greater life satisfaction and well-being than left-wingers, the new study found."Conservatives also scored highest on measures of rationalization, which gauge a person's tendency to justify, or explain away, inequalities...
"Our research suggests that inequality takes a greater psychological toll on liberals than on conservatives apparently because liberals lack ideological rationalizations that would help them frame inequality in a positive (or at least neutral) light."
