As more and more public spaces open back up, many people are finding themselves a little jumpy when they hear someone cough nearby. Are they sick, is it allergies, is it coronavirus?Chances are, we are jumping to conclusions about those “sick” sounds we find disgusting, according to a recently published study from the University of Michigan and University of California, Irvine.“We find no evidence that perceivers can reliably detect pathogen threats from cough and sneeze sounds, even though they are reasonably certain they can,” said Nicholas Michalak, the study’s lead author and a University of Michigan psychology graduate student.In other words, we humans are not very good at distinguishing the seriousness of a cough or sniffle by the sound of it. In fact, the study found that the more disgusting a person perceived the sound to be, the more likely they were to believe the sound came from an infected person, regardless of whether it did.Previous research has indicated people can accurately diagnose infection in others using other senses, like sight and smell.The research is based on four studies that had participants judge whether a cough or sneeze sound came from people infected with a communicable (easily spread) disease or not. On average, participants guessed four out of ten sounds correctly.“Moreover, there was no evidence that accuracy improved when participants knew the true number of infectious sounds in advance or when participants focused on how clear or disgusting they perceived the sounds,” Michalak said. “Despite this poor overall accuracy, perceivers consistently reported reasonable certainty in their judgments.”The study’s authors theorized that people have a belief that a sound that disgusts them is likely to represent a disease threat - this could lead them to exhibit biases to avoid interactions with others who make disgusting but noninfectious noises, according to Mickalak.The study’s co-authors are Oliver Sng, assistant professor of psychological science at UC-Irvine, and U-M graduate student Iris Wang and U-M associate professor of psychology Joshua Ackerman.Read the full study here. 2150

As many public health experts have expressed concern over President Donald Trump's re-election rallies amid the coronavirus pandemic, a study conducted by Stanford University examined the number of illnesses stemming from the rallies.According to the study published last week, the rallies likely caused 30,000 other coronavirus-related infections, resulting in 700 deaths. The study's authors noted that these cases were not specifically from rally attendees, which means that attendees could have spread the virus to others.The study did not use contact tracing; instead, they relied on a statistical model that analyzes the virus's spread in communities Trump held rallies.Specifically, researchers examined 18 rallies Trump held from June 20 to Sept. 22, noting that coronavirus cases in the area near the rallies increased by more than 250 per 100,000 residents."Our analysis strongly supports the warnings and recommendations of public health officials concerning the risk of COVID-19 transmission at large group gatherings, particularly when the degree of compliance with guidelines concerning the use of masks and social distancing is low," the study's authors said. "The communities in which Trump rallies took place paid a high price in terms of disease and death."Trump's rallies have generally included thousands of supporters standing shoulder to shoulder. While masks are often handed to supporters, most supporters at rallies opt not to wear them.Public health experts say that a combination of masks and keeping six feet of distance helps minimize the virus's spread, which has claimed more than 230,000 American lives since the spring.Public health experts have also encouraged people to hold gatherings outside, as most Trump rallies since he resumed campaigning in June have been held outdoors with a few exceptions.Trump has often mocked his opponent Joe Biden, who has held much smaller events to spread out the crowd. Biden has held several "drive-in" style events.Dr. Anthony Fauci, whose recent disagreements with Trump have boiled over on the campaign trail, said in an interview with CNN, he was troubled by Trump's rallies."We know that is asking for trouble when you do that," Fauci told. "We've seen that when you have situations of congregate settings where there are a lot of people without masks, the data speak for themselves."To read the full study, click here. 2403
