NEW YORK (AP) — People are more likely to return a lost wallet if it contains money — and the more cash, the better.That's the surprising conclusion from researchers who planted more than 17,000 "lost wallets" across 355 cities in 40 countries, and kept track of how often somebody contacted the supposed owners.The presence of money — the equivalent of about in local currency — boosted this response rate to about 51%, versus 40% for wallets with no cash. That trend showed up in virtually every nation, although the actual numbers varied.Researchers raised the stakes in the U.S., the United Kingdom and Poland. The response jumped to 72% for wallets containing the equivalent of about , versus 61% for those containing . If no money was enclosed, the rate was 46%.How can this be?"The evidence suggests that people tend to care about the welfare of others, and they have an aversion to seeing themselves as a thief," said Alain Cohn of the University of Michigan, one author who reported the results Thursday in the journal Science.Another author, Christian Zuend of the University of Zurich, said "it suddenly feels like stealing" when there's money in the wallet. "And it feels even more like stealing when the money in the wallet increases," he added. That idea was supported by the results of polls the researchers did in the U.S., the U.K. and Poland, he told reporters.The wallets in the study were actually transparent business card cases, chosen so that people could see money inside without opening them. A team of 13 research assistants posed as people who had just found the cases and turned them in at banks, theaters, museums or other cultural establishments, post offices, hotels and police stations or other public offices. The key question was whether the employee receiving each case would contact its supposed owner, whose name and email address were displayed on three identical business cards within.The business cards were crafted to make the supposed owner appear to be a local person, as was a grocery list that was also enclosed. Some cases also contained a key, and they were more likely to get a response than cases without a key. That led the researchers to conclude that concern for others was playing a role, since — unlike money — a key is valuable to its owner but not a stranger.The effect of enclosed money appeared in 38 of the 40 countries, with Mexico and Peru the exceptions. Nations varied widely in how often the wallet's "owner" was contacted. In Switzerland the rate was 74% for wallets without money and 79% with it, while in China the rates were 7% and 22%. The U.S. figures were 39% and 57%.The study measured how employees act when presented with a wallet at their workplaces. But would those same people act differently if they found a wallet on a sidewalk?"We don't know," said Michel Marechal, an author from the University of Zurich. But he said other analyses suggest the new results reflect people's overall degree of honesty.Shaul Shalvi of the University of Amsterdam, who wrote a commentary that accompanied the study, told The Associated Press that he suspected the study does shed light on how people would act with a wallet found on the street.He said the results "support the idea that people care about others as well as caring about being honest."Robert Feldman, psychology professor at the University of Massachusetts Amherst who didn't participate in the work, said he suspected the experiment might have turned out differently if involved "everyday people" rather than employees acting in an official capacity.But Feldman called the study impressive and said it seems like "a very real result."Dan Ariely, a psychology professor at Duke University who didn't participate in the research, said the conclusions fit with research that indicates keeping a larger amount of money would be harder for a person to rationalize."It very much fits with the way social scientists think about dishonesty," he said. 3987

New research may be hard for some dog owners to accept; the study found that dogs do not understand every word a human says to them.The researchers say dogs cannot hear subtle differences between words the way humans can. For example, the difference between “dog” and “dig” sounds different to human ears, but not so different to dog ears.The researchers came to their conclusion after measuring brain activity of family dogs by taping electrodes to the animals’ heads. They then played recordings of instruction words they knew, like “sit,” then similar-sounding nonsense words, like “sut,” and finally an unrelated nonsense word or sound, like “bep.”The dogs in the study, who were not trained ahead of the study, could quickly tell the difference between the instruction words and the unrelated nonsense words."The brain activity is different when they listen to the instructions, which they know, and to the very different nonsense words, which means that dogs recognize these words," lead study author and postdoctoral researcher at E?tv?s Loránd University in Budapest, Lilla Magyari told CNN.So, the good news is, yes, dogs are listening to human words and understanding some.However, brain activity showed a similar reaction in the dogs between the instruction word and the similar nonsense word.Dogs are renowned for their auditory capacity and ability to hear words and sounds, however the results show they may not be able to distinguish between subtle speech sound differences.Magyari says more research is needed to understand why this is."They may just not realize that all details, the speech sounds, are really important in human speech. If you think of a normal dog: That dog is able to learn only a few instructions in its life," she told CNN.The study was published this week in the Royal Society Open Science journal. 1845

NEWPORT BEACH (CNS) - President Donald Trump is scheduled to come to Orange County Sunday for a private fundraiser at tech mogul Palmer Luckey's estate, it was reported Friday.The news came Thursday, just as latest fundraising numbers showed the president falling behind former Vice President Joe Biden in campaign cash, The Orange County Register reported.Biden reportedly raised a record-breaking 3 million in September to Trump's 7.8 million. And Biden reported 2 million in cash heading into October vs. Trump's 1 million.Invitations for Sunday's fundraiser at Luckey's Newport Beach home show tickets ranging from ,800 for an individual admission to 0,000 for a couple to attend and take a photo with the president, according to the Register. Ric Grenell, Trump's former acting Director of National Intelligence, is also slated to be a special guest at the event.The event was originally slated to take place Oct. 6, but was postponed after Trump contracted the coronavirus. The president says he no longer feels ill and his doctors have cleared him for public appearances. But some experts have expressed concern about him holding in-person events less than two weeks after he was released from the hospital, and they continue to discourage any large public gatherings.Luckey has donated 5,600 to Trump's campaign this cycle, according to Federal Election Commission records. And he's donated more than .7 million total this cycle, with much of the rest of those funds going to GOP committees and Republicans running for seats, such as Michelle Steel and Young Kim, who are both trying to unseat Democratic members of Congress.Luckey is a Long Beach native who was 19 when he co-founded the Oculus Rift virtual-reality system in Irvine. His company sold for an estimated billion to Facebook in 2014. 1838

New plans for student loan debt forgiveness are being proposed as President-elect Joe Biden prepares to take office in just a few weeks. Many of those with student loans, as well as many economists, are hopeful some form of student loan debt forgiveness will pass.“I think it is one of the most accessible ways President-elect Joe Biden has to stimulate the economy,” said Suzanne Kahn, director of education, jobs, and worker power at the Roosevelt Institute in New York.In an interview covering the possible benefits of student loan debt forgiveness, Kahn explained the two ways in which the Biden can get the debt forgiven. One, he can push for Congress to include this debt relief in the next stimulus package, or two, he can take executive action. Either option could eliminate student loan debt for roughly 15 million borrowers and reduce the debt of another 30 million Americans.The president-elect is currently focused on pushing for ,000 to be forgiven in the next stimulus bill and has not said if he would actually consider executive action. However, he has also not refuted that option either.The latter option is certainly the more controversial way to get this debt forgiven, although many Democrats argue it is still legal and fully within a president’s power to do so. Many high-ranking Democrats in Congress explain Biden would have the authority to do this through the Higher Education Act.Experts like Kahn believe it is more likely that Congress will not agree on any amount of student loan debt forgiveness and Biden will take executive action.“I think that it is through executive action, or at least the first movement we see around it will be executive action,” said Kahn. “That really is because the federal government owes 95 percent of student debt, and the Secretary of Education has the ability to cancel it.”“My stance is that it is not inevitable,” said Neal McClusky, director of the Center for Educational Freedom at the Cato Institute.McClusky believes a third option is that no form of student loan debt forgiveness is passed, while he concedes there is a chance that Biden could issue an executive order forgiving student loan forgiveness. However, he also points out that option could be challenged in the courts with some questioning his authority through the Higher Education Act.“There seems to be straws that he can grab and say, ‘Look, this gives me the authority to just write off this debt.’ Other people say it is not clear in the law that he can do that,” said McClusky. “So, what would be the most likely outcome is that he would try. If he were to try and cancel student loan debt through executive action, it would end up in court and would be a pretty long court battle.”So, at the end of the day, where do we really stand with student loan debt forgiveness? The consensus is that it is more likely than ever before that some form of student loan debt will be forgiven, but we’re still nowhere close to a guarantee that will actually happen anytime soon.“I don’t think it is inevitable, but I do think it is important that it is on the table,” said Kahn. 3115
