The faster they talk, the more readily apparent it is that they are lying:
Vaccines are doing their jobs preventing disease and death, and even bringing down societal costs, according to a new study in Pediatrics. But another study, published in the same journal issue, found that public health campaigns touting vaccines’ effectiveness and debunking the links between autism and other health risks might actually be backfiring, and convincing parents to skip the shots for their kids.
“Corrections of misperceptions about controversial issues like vaccines
may be counterproductive in some populations,” wrote the researchers
behind one of the studies, led by Dr. Brendan Nyhan, a health care
researcher at Dartmouth College in Hanover N.H. “The best response to
false beliefs is not necessarily providing correct information.”
It would help if the “corrections of misperceptions” weren’t so easily demonstrated to be false by anyone who is paying even a moderate amount of attention.
