I laughed while reading this NPR story about an article from the Christmas edition in BMJ. It highlighted research about the efficacy of parachutes. This randomized controlled trial concluded that parachutes are no more effective than empty backpacks for safety when jumping out of an aircraft. Yes, you read that correctly!
The devil is in the details. This article was meant to highlight why it is important to read through the laborious details of research methodology rather than skipping to the conclusions, which we are all wont to do (yours truly included!).
I’ll leave it to you to read through the research methodology to find out the simple reason for the alarming conclusions to this research study. Suffice it to say…. I will still grab a parachute in a flight emergency… and skip the empty backpack!
