According to a recent article: “A new study flies in the face of anecdotal evidence and raises questions about how we read data.“
In order to get people to agree to take part in the study, the scientists had to structure the experiment properly. The airplane was both on the ground and stationary, as they thought it would be impossible to get people to agree to leap from a moving plane several thousand feet up without a parachute. The authors admit this was a “minor caveat” in the study’s design.
They don’t admit this until the fourth or fifth paragraph into the paper, however, which leads to their larger point:
Beware of headlines
“Minor” Caveat they say?
Scientists working at medical schools across the United States discovered that parachutes don’t lower the death rate of people jumping out of airplanes.
The study flies in the face of decades of anecdotal evidence.
The findings should be carefully applied, due to “minor caveats” with the experimental structure.
There is an old joke that says “If your parachute doesn’t deploy, don’t worry: you have the rest of your life to fix it.” The findings of a new study may put that joke out of fashion, as intrepid scientists found that jumping out of a plane with a parachute didn’t lower the death rate of test subjects compared to those who jumped without one.………
