Researchers at the University of Missouri have found that citizens of countries with press freedom tend to be much happier than citizens of countries without free presses. ... press freedom directly predicts life satisfaction across the world.
Tandoc also found that countries with higher levels of press freedom enjoyed better environmental quality and higher levels of human development, both of which also contribute to life satisfaction. He credits this to the watchdog function of the press, which helps expose corruption of all levels in a community.
"A country with a free press is expected to be more open about what is wrong in their societies and with their environments," Tandoc said. "A free press is likely to report about poor human conditions and environmental degradation, bringing problems to the attention of decision-makers. It should not come as a surprise, therefore, that press freedom is positively related to both environmental quality and human development." [emphasis mine]
