Evidence & Mechanism

Evidence & Mechanism is the methodological signature of the site: a framework for aligning the strength of a scientific claim with the strength and type of evidence supporting it.

Evidence pathway

From observation to stronger mechanistic inference.

  1. 01Observation
  2. 02Association
  3. 03Perturbation
  4. 04Dependency
  5. 05Rescue / Mediation
  6. 06Stronger mechanistic inference
This pathway is a calibration framework, not a requirement that every study contain every stage.
01

Association is not causation

Observational or correlational relationships should not be described as causal without appropriate perturbation, mediation, transfer, rescue, or dependency evidence.

02

Expression is not function

Changes in expression, abundance, or localization may support a mechanistic hypothesis but do not alone establish functional dependency.

03

Prediction is not validation

Network pharmacology, docking, molecular dynamics, enrichment analysis, computational target prediction, and multi-omics integration are hypothesis-generating or supportive unless experimentally validated.

04

Abundance change is not mediation

A change in a metabolite, microbial taxon, receptor, or pathway marker does not establish that it mediates the observed phenotype.

05

Experimental unit matters

Biological independence, replication structure, donor/animal/sample hierarchy, and pseudoreplication can determine whether an apparent effect is statistically interpretable.

06

Claims should scale with evidence

Language should distinguish association, modulation, involvement, dependency, necessity, sufficiency, rescue, and causation.

The goal is not to make every conclusion stronger. It is to make every conclusion proportionate to the evidence.
