    My two- and four-year-old boys love to win, whether they’re racing their bikes down the sidewalk or just finishing their snacks. It’s true that those with high status, from world leaders and prize winners to athletes and movie stars, are people we like and respect. A recent study published in Nature Human Behaviour showed that we seem to have an innate（天生的）preference for high-ranking peoples——but only if those people aren’t hurtful toward others.

Researchers showed toddlers（aged 21 to 31 months） a scene where two puppets（木偶） approached one another from opposite sides of a stage and one bowed to let the other pass first. Asked which puppet they liked better, 18 of the 21 toddlers in the experiment reached for the puppet who had been allowed to pass. Because respect from others is a marker of status, this suggests that children have a preference for those with a higher status—even before age three.

However, the results were quite different when two puppets approached one another and one used force to knock the other down before continuing to the other side. In this case, 18 of the 21 toddlers reached for the one who was knocked down. As the researchers concluded, “When approaching others, very young children care not only who wins, but also how.” The previous experiment has shown that toddlers know about social status, but this experiment went one step further by proving they have an obvious preference for high status. Since the participants were so young, this might even be an innate human preference.

In a word, this new research suggests that young children appreciate people who do well while at the same time doing good to others. So, when my four-year-old thinks that he has to get his shoes on first, I’ll keep reminding him that helping his brother so they both finish faster is what winning is all about.
