This is an interesting look into the most conservative of the Scandinavian societies. Some of the Finns interviewed for this article liken the conservative nature of the Finnish people to the Japanese, who are notoriously conservative with their emotions.

“Self-control is very important in Finland,” said Dr. Liisa Keltikangas-Jarvinen, a professor of psychology at the University of Helsinki. “You cannot show anger; it means you can’t cope. If a person is very temperamental and alive, expresses emotions like anger and happiness, the person is seen as infantile.”

The article also talks about the modesty of the Finnish, including an inability to boast, which also drives a crisis in self-esteem. That does seem eerily similar to some criticisms of the Japanese psyche, especially after 13+ years of financial depression.

The flip side of this modesty, Dr. Keltikangas-Jarvinen and others say, is that Finns, despite their many advances, particularly in the technological field, seem to suffer from a self-esteem crisis. Theirs is such a consensus-driven, homogenous culture that a free exchange of ideas sometimes proves difficult.
Even among Nordic peoples, the Finns’ stolid nature stands apart.

Mr. Herala, the “anger teacher,” said much would be solved if people could just learn to say what they think and express their emotions, be it “I am angry because,”or “I love you because,” he said.
“We are,” he said, “the Finnish version of the Japanese character.”
