In science and medicine, doctors utilize many kinds of evidence when making health care decisions. Known within the medical community as evidence based medicine (EBM), one of the primary goals is to improve overall decisions by the individual physicians and care team. In a previous study published in the British Medical Journal, researchers argued that some things are so obvious that they do not require ongoing research and even ridiculed the practice of evidence-based medicine.
The example they provided was not needing to judge the effectiveness of a parachute when jumping out of an airplane.
And while that may seem logical because everyone “knows” a parachute helps to improve your chances of survival when jumping from an airplane, EBM can more accurately prove this to be true.
