Multiple observers reduce error by using triangulation and double description to bridge the gap created by the epistemic cut—the necessary separation between the symbolic model (the observer) and the material reality (the system)[1],[2],[3].
Because any single model on the symbolic side of the cut is a simplification that inevitably neglects certain degrees of freedom in the real world, “error” is defined as the divergence between what that model predicts and what the material system actually does[4],[5],[6].
Here is how multiple observers mitigate this divergence:
1. Triangulation via Redundancy
The most basic method of error reduction involves using independent observers to filter out “noise” or individual bias.
• Redundancy of Consequences: If multiple uncorrelated sources (e.g., different sensors or independent witnesses) point to the same conclusion, the probability that the observation is a random error drops significantly[7],[8].
• Filtering Idiosyncrasies: While adding more observers initially increases “entropy” (complexity), this diversity allows an investigator to strip away individual idiosyncrasies and identify the shared constraints or “truth” common to all accounts[8],[9].
2. Double Description (Binocular Vision)
Gregory Bateson used the metaphor of binocular vision to explain how multiple perspectives generate a higher order of insight[10],[11].
• The Bonus of Depth: Just as two eyes provide a “bonus” of depth perception that neither eye has alone, combining two different descriptions of a phenomenon provides an extra dimension of understanding[11],[12].
• Logical Types: The difference between the information provided by Observer A and Observer B is itself a higher logical type of information, allowing for the perception of relationships that are invisible from a single vantage point[12],[13].
3. Seeking Invariance
Objectivity is not achieved by finding a “view from nowhere,” but by identifying properties that remain invariant across different frames of reference[14],[15].
• Transformation of Coordinates: In science, if a property (like a mathematical ratio) remains constant regardless of the observer’s position or measuring equipment, it is considered physically real rather than an artifact of the observation process[14],[15].
• Consistency Checks: Multiple observers help establish “communicable objectivity” by verifying if their results can be replicated across the “cut” by others using different tools[15].
4. Second-Order Observation (Blind Spots)
Handling error requires moving from “what is seen” to “how it is seen”[16].
• Revealing the Blind Spot: Every observer has a “blind spot”—the specific distinctions they use to see the world which they cannot see themselves using[16].
• Recursive Correction: A second observer can observe the first observer’s blind spot, identifying where their model has simplified or distorted reality, thus providing a recursive mechanism for correcting errors that the original observer could never detect[17],[16],[18].
In your own work, do you find that different stakeholders are reporting the same “facts” but reaching different conclusions, or are they seeing entirely different “realities” based on where they stand?
