Will this one weird trick do anything to influence people's beliefs in "studies" ?
It is a joke / quip / truism that any headline that ends with a question mark can be answered "No".
"Will Obama's foreign policy lead us into nuclear war?"
"Are House Republicans trying to reinstitute slavery?"
"Will this superfood let you lose 50 pounds overnight?"
It is another truism that the phrase "according to a study" in a news article has the same semantic weight as "My best friend's sister's boyfriend's brother's girlfriend heard from this guy who knows this kid who's going with the girl who saw it at 31 Flavors last night. I guess it's pretty serious."
An example of the latter:
The Huffington Post reported that McDonald’s could give all of its workers a "living wage" by raising the price of a Big Mac by 68 cents, and it said that this fact came from "a study by a University of Kansas researcher".
…except actually the "study" turned out to be something done by by an undergraduate, and it contained basic math errors.
