+ holidays' effect on the brain; science of holiday spices US Edition - Today's top story: Health misinformation is rampant on social media â here's what it does, why it spreads and what people can do about it [View in browser]( US Edition | 13 December 2023 [The Conversation]
[The Conversation]( When I was a technology reporter in the mid-1990s when the internet exploded, it was easy to believe that people would become better informed â giving access to the worldâs information, the thinking went, would be a boon to people curious to learn about the world. This has turned out to be largely true, but widespread digital connectivity has had a dark side as well: the explosion of misinformation and disinformation. Two stories this week remind us of the harms of false or deliberately misleading content. Boston University public health scholar Monica Wang writes that confidence in vaccines has actually gone down since the start of the COVID-19 pandemic, and misinformation continues to spread. She writes that more than 300,000 deaths between January 2021 and April 2022 in the U.S. could have been prevented if those individuals had been vaccinated. Wong also offers advice on how to [navigate the tangle of sources people confront every day]( when making health care decisions. Meanwhile, disinformation researcher H. Colleen Sinclair provides a picture of the many sophisticated [techniques used to mislead people with disinformation](. She, too, offers some tips on how to be vigilant online. âYou often look into the things you buy rather than taking the advertising at face value before you hand over your money. This should also go for what information you buy into,â she concludes. On a lighter note, scholar Chip Colwell brings his anthropologistâs eye to gift giving. Why do people give gifts, and why is this practice embedded in so many societies? Parsing the writing of a French anthropologist named Marcel Mauss, Colwell may inspire you to [bring a personal touch to any gift giving you do this year](.
