The Role of Evidence
Evidence supports or challenges a claim. In organizational decisions, research and records can make reasoning open to inspection, while experience contributes context and judgment. Both need evaluation for relevance, reliability and the limits of the cases behind them.
THE IDEA
The Role of Evidence
Evidence is information offered to support or challenge a belief or inference. In organizational decisions, it helps people examine competing accounts of what is happening and what a proposed action might achieve. The amount of information is not enough: its relevance, reliability and relationship to the claim matter.
The empirical dimension of the author’s 3E framework emphasizes information that others can inspect, such as records, observations and research findings. This can give a group a shared basis for disagreement and testing. Being external to a decision-maker does not automatically make evidence objective or representative; the way it was collected and interpreted still needs examination.
Experience also informs judgment. A professional may recognize a pattern, notice missing context or suggest a useful explanation from past cases. But those cases may be selective, and beliefs tied to personal competence can be difficult to reconsider. Strong attachment to an experience can make disagreement feel personal rather than evidential.
The 3E framework therefore considers how to combine empirical and experiential sources while making their basis and limits explicit. A group can ask what was observed, how typical it is, what interpretation is being added and what would count against that interpretation. The goal is to give evidence weight for reasons others can examine.
When to use it
Applying evidence hierarchy in corporate strategic planning to balance market data with executive experience.
Balancing empirical and experiential evidence in medical diagnosis to improve accuracy and reduce errors.
Using weight of evidence in legal arguments to strengthen a case with objective facts.
Evaluating policy decisions with both quantitative data and practitioner experience to achieve robust outcomes.
FROM THEORY TO EVERYDAY LIFE
In practice
Market Research vs. Manager's Intuition
A company considering a product launch has customer surveys, sales records and the CEO’s experience with similar launches. The team examines the quality and relevance of each source, then asks where the CEO’s interpretation agrees with the data and where it needs further testing.
Medical Diagnosis
A doctor uses lab test results and clinical studies (empirical) along with personal experience with similar cases (experiential) to diagnose a patient. Evidence-based medicine emphasizes empirical data to reduce bias.
A MOMENT TO REFLECT
Put it to work.
How might your personal experiences bias your interpretation of data in a professional setting?
In a group decision, what methods can ensure that empirical evidence is given due weight over individual experiences?
Describe a situation where experiential evidence overrode empirical evidence and the outcome. What could have been done differently?
