Two heads are better than one. After all, when trying to make decisions, it's good to have a second opinion. But what about a third, fourth — even twelfth? What group size is best for making decisions quickly? For ants, four to six heads surpass one ― and also outperform 12 or 24. That's what Sylvia Zamescu now reports.

The 18-year-old senior at Catalina Foothills High School in Tucson, Arizona isn't generally into ants. She's interested in decision-making, especially by people. Last summer, Sylvia read that social insects such as ants and bees can be used to model decision-making. Ants, for example, forage for food. When an ant finds it, it takes a bite and heads back to the nest. On the way; the ant leaves a scented trail for other ants to pick up. Back at the nest, the ant vomits up its meal into the mouth of other ants. Those nest-mates then decide with the first ant whether the food is good enough to deserve a trip back for more. If it is, they follow the first ant's scented trail to lunch.

When there are too few ants, it could take a long time for one ant to spread the word If there are too many, it's hard to “tell" each about the find. What's the right number for foraging success? Sylvia decided to find out. She contacted professors at the University of Arizona in Tucson to look for someone who would let her study decision-making by ants in their lab. Professor Wulfila Gronenberg answered her email.

Working with one of Wulfila's graduate students, Sylvia set up an experiment She tested the behavior of one, two, four, six, twelve and twenty-four ants. Each group was placed in a large box al taped "starting line". At the other end of the box were two bricks of sweetened gelatin （动物胶） one contained only 3 per cent sugar, and the other 30 per cent. Sylvia timed how long it took each group of ants to find the food. She also measured how much time they spent around each sweet treat.

When there were just one or two ants, the discovery was slow. The same was true when she set twelve or twenty-four ants loose. But four to six ants? Perfect! These medium-size groups found the food forest. They also figured out quickly that the sweeter food was better.

Similar work has been done on bighorn sheep, fish and fruit flies. "It may not be four to six animals, but it's the same principle," Sylvia says. A medium-size group "is optimal". So when faced with a new decision, two heads are better than one. But too many heads are too much. Like the ants, a good decision may just require a happy medium.

1.What gave Sylvia the idea for her research?

A.Her interest in social insects.

B.An article about social animals.

C.A university professor's invitation.

D.Her doubt about a science report.

2.What do we know about Sylvia's experiment?

A.She set it up with Professor Wulfila Gronenberg.

B.There were two large boxes at the "starting line".

C.There were several kinds of foods for the ants.

D.She divided the ants into six different groups.

3.What did Sylvia find out about ants?

A.They make decisions faster in medium-sized groups.

B.They are better at finding food in smaller groups.

C.They perform much more smartly in larger groups.

D.They make better decisions when working together.

“Whatever your job is, the chances are that one of these machines can do it faster or better than you can.”

As innovation accelerates, thousands of jobs will disappear, just as it has happened in the previous cycles of industrial revolutions. Machines powered by narrow AI algorithms can already perform certain 3-D tasks (“dull, dirty and dangerous”) much better than humans. This may create enormous pain for those who are losing their jobs over the next few years, particularly if they don't acquire the computer-related skills that would enable them to find more creative opportunities. We must learn from the previous waves of creative destruction if we are to lessen human suffering and increasing inequality.

For example, some statistics indicate that as much as 3% of the population in developed countries work as drivers. When automated cars become a reality in the next 15 to 25 years, we must offer people who will be “structurally unemployed” some sort of compensation income, training and re-positioning opportunities.

Fortunately, the Schumpeterian waves of destructive innovation also create jobs. History has shown disruptive innovations are not always a zero-sum game. In the long run, the loss of low-added-value jobs to machines can have a positive impact in the overall quality of life of most workers.

The ATM paradox is a good example of this. As the use of automatic teller machines spread in the 1980s and '90s, many predicted massive unemployment in the banking sector. Instead, ATMs created more jobs as the cost of opening new agencies decreased. The number of agencies multiplied, as did the portfolio of banking products. Thanks to automation, going to the bank offers a much better customer experience than in previous decades. And the jobs in the industry became better paid and were of better quality.

This optimist scenario assumes, however, that education systems will do a better job of preparing our children to become good at what humans do best: creative and critical thinking. Less learning-by-heart and more learning-by-doing. Fewer clerical skills and more philosophical insights about human nature and how to cater to its infinite needs for art and culture.

To become creative and critical thinkers, our children will need knowledge and wisdom more than raw data points. They need to ask “why?”, “how?” and “what if?” more often than “what?”, “who?” and “when?” And they must construct this knowledge by relying on databases as cognitive partners as soon as they learn how to read and write.

Thus, the future of human-machine cooperation looks less like the scenario in the Terminator movies and more like a Minority Report-style of “augmented intelligence”. There will be jobs if we adapt the education system to equip our children to do what humans are good at: to think critically and creatively, to develop knowledge and wisdom, to appreciate and create beautiful works of art. That does not mean it will be a painless transition. Machines and automation will likely take away millions of low-quality jobs as it has happened in the past. But better-quality jobs will likely replace them, requiring less physical effort and shorter hours to deliver better results.

It's a small business 1 started, and everyone who enjoy, working here comes into the studio in free time, so they can be home with their family, cats, dogs at prime times.
