Preschool boys in Norway prefer larger groups over smaller ones
Researchers at the University of Oslo found that preschool boys in Norway chose characters from bigger groups more often than those from smaller groups.

Study participants and setup
The team recruited 153 children between the ages of 3 and 6 for the experiment. Animations showed two separate groups of colored characters with faces moving on opposite sides of a screen without fighting.
Children selection results
About 65 percent of the boys selected the member belonging to the larger group of three. In contrast, roughly 43 percent of the girls made that same choice while others showed no clear preference.
Adult gender differences
Adult participants displayed different choices based on their gender rather than simply picking the bigger option. The researchers noted that these adult selections were weakly linked to attitudes toward social inequality.
