バレンタインの統計学と経済学

以前書いたように、バレンタインデーにカップル成立が多いというのは、フェイスブックのデータも示している。もちろん全然不思議なことではない。

What Days Are People Getting Together?

The days around Valentine's Day and Christmas are good chances to try your luck or breathe a bit easier. The data showed far more people paired up around these times than joined the ranks of the newly single.

Feb. 14: 49% more new relationships than break-ups
Dec. 25: 34% more
Dec. 24: 28% more
Feb. 15: 22% more



一方で、こうしたデータはフェイスブック上の "status" に基づいているわけで、そもそもどういう人がその status を表示・更新しているのかというのは、なかなか面白い視点だと思う。以下は、ニューヨーク・タイムズ紙の最近のコラム "Should We Make It Facebook Official?" からの抜粋。なるほどねー。

Recent research suggests that the decisions people make about whether and how to represent their love lives on Facebook can often be quite telling. For example, my colleagues and I found that people who post a “Single” relationship status on Facebook have more sexual partners between relationships than those who opt out of posting “Single” on their profile. We also found that people who disclose that they are “In a Relationship” on Facebook also report being more committed to that relationship. Even among married people, we found that those whose primary Facebook photos include their spouses are less likely to split up 6 months later.



そういえば昨年話題になった、この "14 Ways an Economist Says I Love You" はナイスだったね。

最後にもう一つ、ちょっと古いデータなのだが、"the relationship between chocolate and sex" について。

In some parts of Europe sex and chocolate go hand in hand, though a causal link is unclear. Mediterranean lovers tend to have as much sex but less chocolate—perhaps hotter weather has a bearing on both. The Japanese have precious little of either.
