Philosophy of Evidence-Based Orthodoxy

A branch of philosophy that examines the nature, justification, and implications of evidence-based orthodoxy—asking philosophical questions about the foundations of evidence-based approaches themselves. The philosophy of evidence-based orthodoxy investigates the epistemological status of evidentiary hierarchies: Are RCTs really always the best evidence? How do we know that systematic reviews are reliable? What counts as evidence for the evidence hierarchy itself? It also examines the values embedded in evidence-based approaches: Whose evidence counts? What kinds of knowledge are excluded? How do evidentiary standards serve institutional interests? The philosophy of evidence-based orthodoxy is essential for evidence-based practice to be self-aware rather than merely assumed, for practitioners to understand the philosophical foundations of their methods rather than treating them as self-evident.

Example: "His philosophy of evidence-based orthodoxy work asked whether the evidence hierarchy can justify itself—or whether it's a matter of faith that RCTs are best, since the claim itself hasn't been tested by RCT. Evidence-based practice may rest on foundations it can't examine with its own tools."

Sociology of Evidence-Based Orthodoxy

A branch of sociology that examines how evidence-based orthodoxies are socially constructed, maintained, and challenged within professional communities. The sociology of evidence-based orthodoxy investigates how evidentiary hierarchies become institutionalized through training, how they're maintained through professional standards and funding priorities, how alternative approaches (qualitative research, community knowledge, practitioner experience) are marginalized, and how the orthodoxy responds to challenges from those who question its hierarchy. It also examines the role of evidence-based orthodoxy in professional boundary-work—distinguishing "real" professionals from "quacks," "scientific" practice from "anecdotal" approaches, "legitimate" knowledge from "mere" experience. The sociology of evidence-based orthodoxy reveals that evidentiary hierarchies aren't just about epistemology; they're also about professional power, institutional authority, and the social construction of expertise.

Example: "Her sociology of evidence-based orthodoxy research showed how the hierarchy of evidence serves professional interests—elevating researchers over practitioners, quantitative over qualitative expertise, academic knowledge over community wisdom. The hierarchy isn't just about truth; it's about who gets to say what counts."

Chilling Effect Theory (Evidence)

A framework analyzing how the demand for “evidence” can chill inquiry when the standard of evidence is set so high that certain questions become unaskable. Demanding “peer-reviewed evidence” for emergent phenomena, or insisting on RCTs for historical claims, effectively bans research on those topics. The chilling effect operates through the pre-emptive dismissal of non-standard evidence sources. It explains why fields like disaster response, rapid emergence, or indigenous knowledge are systematically understudied.

Example: “Community knowledge about local flood patterns was dismissed by researchers demanding ‘published studies.’ Chilling Effect Theory (Evidence) shows how evidence standards can silence the only available data.”

decision-based evidence making

An alternative to evidence-based decision making, "decision-based evidence making" is the practice of collecting evidence to support a pre-existing decision, rather than using evidence in any way to inform the decision itself.

This technique typically involves cherry-picking sources or relying on bad or unreliable authorities to justify or legitimise (after the fact) a questionable decision which has already been made.

Dr. Daniel Jernigan resigned from CDC in 2025, telling reporters that Robert F Kennedy Jr seems to be "going from evidence-based decision making to decision-based evidence making" as the Centres for Disease Control began citing debunked studies to support a dodgy claim that vaccines cause autism.

Hard Problem of Evidence

The interpretive gap: Evidence is never self-interpreting; it is always filtered through a prior framework of beliefs, theories, and assumptions (a "paradigm"). A single piece of data can be used to support wildly different conclusions. The hard problem is that there is no such thing as "raw" or "theory-neutral" evidence. What counts as evidence, and how much weight it carries, is determined by the very worldview it is meant to test. This creates a hermeneutic circle where beliefs shape the evidence, which then selectively confirms beliefs.

Example: Two people see the same rainbow. A physicist sees evidence of refraction and wavelengths. A theologian sees evidence of a divine covenant. A pot of gold enthusiast sees evidence of leprechauns. The photons hitting their retinas are identical. The hard problem: The "evidence" of the rainbow is not in the light, but in the interpretation. In a courtroom, a fingerprint is strong evidence only if you already believe in the reliability of forensic science and the integrity of the chain of custody. Evidence is a conversation, not a commandment. Hard Problem of Evidence.

Hard Problem of Scientific Evidence

The problem of underdetermination: For any given body of scientific evidence, there are always multiple, logically possible theories that can explain it equally well. Data alone cannot force us to choose one theory over another; extra-scientific criteria like simplicity, elegance, or compatibility with other established theories (paradigm loyalty) must be used. The hard problem is that these criteria are aesthetic and pragmatic, not purely empirical. Thus, the move from evidence to theory is never a strict logical deduction, but a creative, sometimes subjective, leap.

Example: Centuries of astronomical evidence (planetary motions) could be explained perfectly by either Ptolemy's complex earth-centered model (with epicycles) or Copernicus's simpler sun-centered model. The evidence alone didn't decide. The choice was made based on the principle of parsimony (simplicity), which is a philosophical preference, not a law of nature. Today, the weird results of quantum experiments are explained by both the Copenhagen interpretation and the Many-Worlds interpretation. The evidence fits both; our choice is a matter of metaphysical taste, not evidential compulsion. Hard Problem of Scientific Evidence.

Law of Absolute and Relative Evidence

The principle that evidence operates in two modes: absolute evidence (facts that are evidence regardless of perspective, context, or interpretation) and relative evidence (facts that serve as evidence only within particular frameworks, for particular purposes, to particular audiences). The law acknowledges that some evidence is universally compelling—a video of a crime, a DNA match, a document with a signature. Other evidence is context-dependent—statistics that prove one point to one audience and the opposite to another, testimony that's credible in one culture and suspect in another. The law of absolute and relative evidence reconciles the intuition that evidence should be objective with the reality that its force depends on who's judging. Good arguments use both kinds, building on undeniable facts while understanding that interpretation is always relative.

Example: "They argued about whether the data was evidence of climate change. Absolute evidence: the temperature readings were real, measurable, undeniable. Relative evidence: whether those readings proved catastrophic warming depended on models, interpretations, and assumptions. The law of absolute and relative evidence said: the data was absolute; its meaning was relative. They stopped arguing about the data and started arguing about interpretation."
