“America’s reign of optimism contributes to a culture in which negative feelings are often unwelcome. […] As I pondered the question Americans often posed to me—Why aren’t Finns more optimistic, despite their supposedly great society?—I began to turn it around into a different question, a question that seemed to me the more relevant one: How have Finns managed to build such a great society, despite all their negativity? Perhaps the answer is that Finns have built a great society because of their pessimism, not in spite of it. The volume of outrage and complaints that pour out of Finns whenever they perceive an injustice in their society can be annoying—especially when that injustice might be considered minor in other countries. Nevertheless, perhaps this capacity for negative response is part of the secret of Finnish success. Finns are quick to demand real changes that improve their external circumstances.”
