​​Making Sense of Disagreements
We find most differences between reputable experts are due to one or more of the following...
-
The basics are not in dispute. Rather, the arguments focus on refinements for that last 10-20% optimization. These details typically apply to an individual's specific needs or priorities like elite performance or managing a specific concern.
-
Over simplified messaging designed to drive a specific behavior lacks the detail and nuance required to accurately present what is known.
-
Small studies show positive results for a new protocol and/or a growing body of anecdata send promising signals. However, the gold standard of large Random Control Trial (RCT) research has yet to be done to validate and/or identify the mechanism. Trusted experts may disagree on sufficiency of evidence for recommending new protocols in these situations.

Good science involves healthy debate and inevitably different conclusions from much of the study observations. We do our best to put context around these differences so you are aware of reasons reputable expert opinions sometimes differ so you can make your own decision about what makes most sense to you.​
Please note...Playbooks are designed to be both filter and portal to trusted information.
​
As a filter, details are limited to key takeaways and references to trusted resources that are specific to the topic under discussion. The need to filter means many details and resources we trust and value may not yet be presented. It also means there are many positions we do not discuss because we find them to be incompatible with our interpretation of the evidence.

Our choices are based on one guiding principle: to focus on fundamentals offering the best evidence for the best return on your investment of time and effort!
