Reading the Evidence
A study is only as strong as the question it actually asked, the model it actually used, and the conclusions it can actually support. This is the standard Legend Research holds every guide, registry entry, and comparison to.

Six Tenets for Reading the Evidence
Start With the Research Question
A study is evidence for the question it actually investigated—not every broader claim that could be associated with its subject.
Identify the Model
Cells, isolated tissues, animals, observational human data, and controlled human studies are not interchangeable. The model determines what conclusions the experiment can reasonably support.
Separate Mechanism From Outcome
Showing that a molecule interacts with a receptor or signaling pathway establishes something different from demonstrating a downstream biological outcome. Mechanistic plausibility is evidence—not proof of every proposed effect.
Read the Method, Not Just the Result
Sample size, controls, endpoints, analytical techniques, experimental conditions, statistical methods, and study duration can materially change how a result should be interpreted. A headline number without methodology is incomplete evidence.
Look for Replication
One striking experiment can generate a hypothesis. Confidence becomes stronger when findings survive independent replication, different models, different laboratories, and stronger study designs.
Keep the Conclusion Inside the Evidence
Animal findings should remain animal findings. Associations should remain associations. Preclinical mechanisms should remain preclinical mechanisms. Early human findings should not automatically become established clinical conclusions.
The strength of a scientific claim should never exceed the strength of the evidence supporting it.
