Nine-month-olds show a preference for helpers over hinderers in a box test

A new look at how babies see the world reveals something surprising. Nine-month-old infants were shown a puppet that either helped or hindered another character. The babies were then asked to choose which puppet to play with. Most of the time, they picked the helper. This suggests that even very young children notice who is being kind and who is not. The study combined data from seven different labs to get a clearer picture. It looked at babies in Norway and Indonesia, plus experiments in North America. The results showed that 58 percent of infants chose the helper. This is a small but consistent signal that babies care about fairness. However, the biggest differences appeared in North American studies. Nearly all of those experiments came from a single lab. This makes it hard to know if the same pattern holds everywhere. The findings are interesting but need more testing in different places to be sure.
