Best Practices in Medicine Should Rely on Providers' Knowledge, Skills and Experience, Not Just Studies
In 2005, a physician-scientist research pioneer, John Ioannides, published what has come to be a widely circulated paper, “Why Most Published Research Findings Are False.” The replication crisis we’re having in science embodies the concern voiced by Mr. Ioannides. Yet, despite much evidence that so many studies are not valid, scientific professionals continue to rely almost exclusively on study results when deciding on best practices.
So many studies are flawed. As a simple example, please take my survey by answering the following question:
Over the past 12 months, how many times have you visited a doctor?
Take as much time as you need to answer the question…
Got your answer?
Okay, now let me ask you a few questions about the number of visits you just “reported” for my study.
First, to answer my question, did you just think back in your mind, or did you actually check your records? Most people will probably come up with a “good estimate” based on what they can quickly recall. Relatively few people will make the effort to reference records to help them come up with a more accurate estimate.
As for what we remember, researchers continue to discover new ways in which our memories paint an inaccurate portrait of “the truth” (to the extent the truth exists). For example, the telescoping effect is a common cognitive bias affecting our memory, where we tend “to displace recent events backward in time and remote events forward in time, so that recent events appear more remote, and remote events, more recent.” The telescoping effect is just one of many different cognitive biases – Wikipedia lists 42 different cognitive biases that affect our memories – any one of which may cause your reported number of visits to the doctor over the past 12 months to be more or less than the “true” number.
Second, what types of providers did you include in your estimate? Did you include any visits to a dentist, nurse practitioner, therapist, optician, optometrist, pharmacist, herbalist, or other allopathic provider? Different people will have different interpretations of what’s included in the category “doctor.”
