What makes a group smart and able to solve problems successfully and make good solutions? Oh, we may ask: what makes a group intelligent? A group’s IQ (智商), we might think, would be simply the average intelligence of the group members, or perhaps the intelligence of the smartest group member. But some scientists have found that this isn’t so.

A group’s intelligence comes out from communications(交流) within the group. A group’s intelligence can be calculated, and like the IQ grades of a single person, and it can predict the group’s performance on lots of kinds of tasks perfectly. A single person’s intelligence can be trained to develop, so can a group’s intelligence. Here are some suggestions on how to guide the development of smart groups:

Personally, you can choose group members carefully. The smartest groups are made of people who are good at reading each other’s social signs. And then it’s better for you to talk about the “how”. Groups who take the time to discuss how they will work together are more well-organized and successful.

As a group member, it is also very important for you to share the information in the formal meetings. The members who just control the discussion or who stay away and don’t say much make the intelligence of the group lower. But in the smart group, members connect directly with each other, not just with group leader. They always take an active part in every small conversation that could be added to main discussion. Outside of formal meetings, the smartest groups spend a lot of time communicating, too. All members can have a coffee break at the same time, leading them to do their work more professionally and feel more pleased with their jobs.

What is one thing that would help parents understand their kids better? More than 8,000 US kids answered this question in an online poll (投票) by KidsHealth.org.

Many US kids — two out of three — said they get along with their parents. But that doesn’t mean they never disagree. In fact, most kids reported arguing with their parents, at least sometimes. And two out of five kids said arguments sometimes even include shouting at each other.

“It’s certainly normal to disagree and argue,” says Darcy Lyness, an American expert. “But it’s also important to learn how to do so respectfully (尊重地). Be patient. Don’t use a raised, angry voice.”

And not surprisingly, three out of four kids said they had lied to their parents sometimes. Many said they lie so they would not get in trouble or disappoint their parents. According to Lyness, lying isn’t just wrong. It can actually have bad results. Telling the truth builds trust.

Telling the truth, says Lyness, shows maturity (成熟). But older kids actually lie more often than younger ones. Kids aged 12 to 14 not only said they lie more, but they also reported having less fun, feeling less close and not getting along as well with their parents.

According to Lyness, those feelings are common. As kids become more independent (独立), they have more areas of disagreement with their parents. But it doesn’t have to be that way. “Kids and parents get along differently at each stage of the journey,” she says. “As kids grow and change, it is important for everybody to change.”
