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

NOGALES, Ariz. – In the war on drugs, the U.S.-Mexico border is the front line.According to Customs and Border Protection, the pandemic is changing how the cartel and other drug organizations are getting narcotics across and into the United States.“Initially we were seeing small football-shaped bundles [full of drugs] being thrown over the fence,” said Sabri Dickman, the border patrol agent in charge along a 33-mile stretch of border near Nogales, Arizona. “We’ve seen that expand to backpack operations with 100-plus pounds to catching vehicles loaded with 600-plus pounds.”The Nogales border crossing is one of the most exploited by Mexican drug organizations. According to CBP, of the more than 200 known underground tunnels that are used to traffic drugs across the southern border, 114 are located in Nogales.It also is one of the busiest as the Mariposa Port of Entry, the main thoroughfare between the countries in Nogales, ushers million in merchandise between the United States and Mexico each day, according to CBP.Mariposa Port Director Michael Humphries says 98% of the traffic that comes through the port is legal, but the 2% is now being used to traffic more hard narcotics like fentanyl, a synthetic opioid similar to morphine, but around 50 to 100 times more potent which makes it lethal even in small doses. Humphries says the hard narcotics are smaller, making them easier to conceal and transport as more can be trafficked in one trip.“We’ve seen an increase in fentanyl over the last year,” said Humphries. “Nogales is a small city [of] 20,000 people. Those tablets of fentanyl weren’t coming to the border. It was going way beyond. It was going to Vermont, and Ohio, Kentucky, and Detroit.”Humphries says in June alone, CBP seized 875,000 tablets of fentanyl from smugglers. It was part of a year that saw officers seize 9,500 pounds of methamphetamine, 900 pounds of fentanyl, and 1,000 pounds of heroine, even though traffic through the port has decreased 60 to 70% because of travel restrictions imposed because of the pandemic.Humphries says those restrictions have led drug organizations to recruit more Americans to smuggle their drugs instead of Mexican or Central American nationals, since U.S. citizens can travel more freely across the border. 2290

New wildfires ravaged bone-dry California during a scorching Labor Day weekend that saw a dramatic airlift of more than 200 people trapped by flames and ended with the state’s largest utility turning off power to 172,000 customers to try to prevent its power lines and other equipment from sparking more fires.California is heading into what traditionally is the teeth of the wildfire season, and already it has set a record with 2 million acres burned this year. The previous record was set just two years ago and included the deadliest wildfire in state history — the Camp Fire that swept through the community of Paradise and killed 85 people.That fire was started by Pacific Gas & Electric power lines. Liability from billions of dollars in claims from that and other fires forced the utility to seek bankruptcy protection. To guard against new wildfires and new liability, PG&E last year began preemptive power shutoffs when conditions are exceptionally dangerous.That’s the situation now in Northern California, where high and dry winds are expected until Wednesday. PG&E received criticism for its handling of planned outages last year. The utility said it has learned from past problems, “and this year will be making events smaller in size, shorter in length and smarter for customers.”Two of the three largest fires in state history are burning in the San Francisco Bay Area. More than 14,000 firefighters are battling those fires and about two dozen others around California.The fire danger also is high in Southern California, where new fires were burning in Los Angeles, San Bernardino and San Diego counties. The U.S. Forest Service on Monday decided to close all eight national forests in the region and to shutter campgrounds statewide.“The wildfire situation throughout California is dangerous and must be taken seriously.” said Randy Moore, regional forester for the Forest Service’s Pacific Southwest Region that covers California. “Existing fires are displaying extreme fire behavior, new fire starts are likely, weather conditions are worsening, and we simply do not have enough resources to fully fight and contain every fire.”Lynne Tolmachoff, spokeswoman for the California Department of Forestry and Fire Protection, or Cal Fire, said it’s “unnerving” to have reached a record for acreage burned when September and October usually are the worst months for fires because vegetation has dried out and high winds are more common.While the two mammoth Bay Area fires were largely contained after burning for three weeks, firefighters struggled to corral several other major blazes ahead of the expected winds. Evacuation orders were expanded to more mountain communities Monday as the largest blaze, the Creek Fire, churned through the Sierra National Forest in Central California.It was one of many recent major fires that has displayed terrifyingly swift movement. The fire moved 15 miles (24 kilometers) in a single day during the weekend and burned 56 square miles (145.04 square kilometers). Since starting Friday from an unknown cause. it has burned 212 square miles (549 square kilometers).Debra Rios wasn’t home Monday when the order came to evacuate her hometown of Auberry, just northeast of Fresno. Sheriff’s deputies went to her ranch property to pick up her 92-year-old mother, Shirley MacLean. They reunited at an evacuation center.“I hope like heck the fire doesn’t reach my little ranch,” Rios said. “It’s not looking good right now. It’s an awfully big fire.”Mountain roads saw a steady stream of cars and trucks leaving the community of about 2,300 on Monday afternoon.Firefighters working in steep terrain saved the tiny town of Shaver Lake from flames that roared down hillsides toward a marina. About 30 houses were destroyed in the remote hamlet of Big Creek, resident Toby Wait said.“About half the private homes in town burned down,” he said. “Words cannot even begin to describe the devastation of this community.”A school, church, library, historic general store and a major hydroelectric plant were spared in the community of about 200 residents, Wait told the Fresno Bee.Sheriff’s deputies went door to door to make sure residents were complying with orders to leave. Officials hoped to keep the fire from pushing west toward Yosemite National Park.On Saturday, National Guard rescuers in two military helicopters airlifted 214 people to safety after flames trapped them in a wooded camping area near Mammoth Pool Reservoir. Two people were seriously injured and were among 12 hospitalized.On Monday night, a military helicopter landed near Lake Edison to rescue people trapped by the fire, the Fresno Fire Department said on Twitter. There was no immediate number of how many people were airlifted.Chief Warrant Officer Joseph Rosamond, the pilot of a Chinook helicopter, said visibility was poor and winds increasingly strong during the three flights he made into the fire zone during the operation that started late Saturday and stretched into Sunday. His crew relied on night-vision goggles to search for a landing spot near a boat launch where flames came within 50 feet (15.24 meters) of the aircraft.The injured, along with women and children, took priority on the first airlift, which filled both helicopters to capacity, he said.“We started getting information about how many people were out there, how many people to expect, and that number kept growing. So we knew that it was a dire situation,” Rosamond said.In Southern California, crews scrambled to douse several fires that roared to life in searing temperatures, including one that closed mountain roads in Angeles National Forest and forced the evacuation of the historic Mount Wilson Observatory. Late Monday night, the Los Angeles County Fire Department told residents of Duarte, Bradbury and Monrovia near the forest to get ready for a possible evacuation.Cal Fire said a blaze in San Bernardino County called the El Dorado Fire started Saturday morning and was caused by a smoke-generating pyrotechnic device used by a couple to reveal their baby’s gender. In eastern San Diego County, a fire destroyed at least 10 structures after burning 16 square miles (41.44 square kilometers) and prompting evacuations near the remote community of Alpine in the Cleveland National Forest.California has seen 900 wildfires since Aug. 15, many of them started by an intense series of thousands of lightning strikes in mid-August. There have been eight fire deaths and more than 3,300 structures destroyed.___Weber reported from Los Angeles along with contributing Associated Press journalist Frank Baker. 6631
