A new study suggests that, for modern Japanese speakers, two traditional, patriarchal words for “husband” (“shujin,” literally meaning “master”) and “wife” (“kanai,” “inside-the-house”) may be losing their original meanings, though men in the study evaluated both traditional and neutral words for “husband” more positively than words for “wife.” Ri Nin and Kazuo Mori of Tokyo University of Agriculture and Technology, Japan, present these findings in the open access journal PLOS One on June 3, 2026.
A new Dartmouth study maps the interplay of personal choice and social networks that can lead to a phenomenon they call "overarming," where the collective cost of firearm ownership outweighs the individual benefits of possessing a gun. The team developed a model based in evolutionary game theory to characterize how social factors drive individuals' choices to buy a firearm, how these choices influence others' choices, and whether the choices made by all members of society leads to overarming.
