Ants Best Humans At Test of Collective Intelligence

3 months 3 weeks ago
Christie Wilcox reports via Science.org: Both longhorn crazy ants (Paratrechina longicornis) and humans can figure out how to work together to move an unwieldy object through a series of obstacles. So scientists pitted the two against each other. They had individuals and groups of different sizes of both species maneuver a T-shaped object through holes in walls (as seen in the video above), both of which were scaled to the body size of the participants. This kind of puzzle is hard for ants because their pheromone-based communication doesn't account for the kind of geometry needed to get the object through the doors. To make the experiments even more comparable, the team also took away the humans' communication in some of the trials by making them wear sunglasses and masks and forbidding talking and gestures. So the people, like the ants, had to work together without language, relying on the forces generated by their fellow participants to figure out how to move the T-shaped piece. The groups of ants were much better at solving the puzzle than individual ants, exhibiting what the researchers described as "emergent" collective memory -- an intelligence greater than the sum of its parts. The groups of humans, on the other hand, often didn't do better when working together, especially if they weren't allowed to talk. In fact, multiple people sometimes performed worse than individuals -- and worse than the ants. The researchers posit that, in the absence of the ability to discuss and debate, individuals attempt to reach a consensus quickly rather than fully assessing the problem. This "groupthink," they suggest, leads people toward fruitless "greedy" efforts where they directly pull the T toward the gaps in the wall, rather than the less obvious, correct solution of pulling the object into the space between first. Whereas the ants "excel in cooperation," they write, humans need to be able to talk through their reasoning to avoid simply going with what they think the crowd wants. The study has been published in the journal Proceedings of the National Academy of Sciences.

Biden To Further Limit AI Chip Exports In Final Push

3 months 3 weeks ago
The Biden administration plans one additional round of restrictions on the export of AI chips before leaving office, "a final push in his effort to keep advanced technologies out of the hands of China and Russia," reports Bloomberg. From the report: The US wants to curb the sale of AI chips used in data centers on both a country and company basis, with the goal of concentrating AI development in friendly nations and getting businesses around the world to align with American standards, according to people familiar with the matter. The result would be an expansion of semiconductor caps to most of the world -- an attempt to control the spread of AI technology at a time of soaring demand. The regulations, which could be issued as soon as Friday, would create three tiers of chip trade restrictions, said the people, who asked not to be identified because the discussions are private. At the top level, a small number of US allies would maintain essentially unmitigated access to American chips. A group of adversaries, meanwhile, would be effectively blocked from importing the semiconductors. And the vast majority of the world would face limits on the total computing power that can go to one country. Countries in the last group would be able to bypass their national limits -- and get their own, significantly higher caps -- by agreeing to a set of US government security requirements and human rights standards, one of the people said. That type of designation -- called a validated end user, or VEU -- aims to create a set of trusted entities that develop and deploy AI in secure environments around the world.
