A new “YouGov survey finds that most Americans — 54% — believe that Lee Harvey Oswald definitely or probably did not act alone in assassinating John F. Kennedy in 1963. Large shares of Americans, though fewer than half, also believe other unfounded claims, including that Barack Obama was not born in the United States (31%) and that voting machines were programmed to change votes in the 2020 election (29%). One in five or fewer think it’s likely true that the government is using COVID-19 vaccines to microchip Americans (20%), that the government was behind the 9/11 attacks (20%), or that the 1969 moon landing was staged (18%). A large share — 41% — believe a broader theory: that regardless of who is officially in charge of the government and other organizations, there is a single group of people who secretly control events and rule the world together.”
