Monkeys Succumb to Peer Pressure, Study Suggests

You don't have to be a teenager to want to fit in at the school lunchroom. Some wild animals seem to follow similar monkey-see, monkey-do behavior to follow the crowd and find the best eats, new research finds.

South African monkeys switched foods purely because of peer pressure, suggest the results of a study in Thursday's journal Science.

"We're not as unique as we would like to think," said lead author Erica van de Waal, of the University of St. Andrews in Scotland. "We can find many of the roots of our behaviors in animals."

For her study, 109 vervet monkeys living in groups in the wild were given a choice of food tinted pink or blue by the researchers. One color for each group was tainted with aloe to give it a harmless yucky flavor. After a few meals, the food was no longer tainted, but the monkeys still wouldn't eat the color they figured was bad.

But that changed when some of them tried to fit in with a new group of monkeys. Blue-food eaters instantly switch when they moved to an area full of pink-food eaters, even though they shunned pink food before. Pink eaters also changed when they moved to a blue-food area.

The social pressure may be like "teenagers with a desperate need to be just like the other guys," said co-author Andrew Whiten, also of St. Andrews. Or it could be that the monkeys are learning to adapt to local custom think restaurant reviews or the old saying "when in Rome, do as the Romans do," he said.

The researchers were surprised by the finding: They were only aiming to find out if mothers taught their young the same color food preference they learned, Whiten said. The next generation automatically ate the same as their mother, showing how food choice is learned.

Just by sheer luck, some blue-eating monkeys went to the pink-eating tribes and some pink-eating males went to blue tribes. And that's when the researchers saw peer pressure in action

Of the 10 migrating males, nine instantly ate what everyone else ate. The only hold out was an alpha male, who stuck to his previous diet.

Van de Waal said it could be the eat-what-locals-eat idea, but she favors the social conformity, peer pressure concept. She figures the other males were trying to get in good with females, while the dominant male acted as "if he's already in charge, why does he need to do like the others."

I believe I see this in the behaviors of many different animals

Thanks --- I would assume that any social animal would be doing or showing this type of behavior! Interesting to know!

Nothing quite like Monkey See, Monkey do and wanting to fit in. Interesting.
