Measuring and interpreting pervasive heterogeneity, poikilosis

Area of Science:

• Metrology and Scientific Measurement
• Experimental Design and Data Analysis
• Heterogeneity and Variation Studies

Background:

• Measurements are fundamental to scientific progress but their underlying assumptions are rarely questioned.
• The concept of poikilosis, pervasive heterogeneity across all scales, challenges the validity of traditional measurement approaches.
• Single-point measurements are rendered obsolete by the inherent variability (intervals of magnitudes) of measurands.

Purpose of the Study:

• To introduce and define poikilosis as a critical factor in scientific measurements.
• To propose a new framework for experimental design, data analysis, and interpretation that accounts for poikilosis.
• To demonstrate how considering poikilosis can resolve scientific disputes and improve measurement reproducibility.

Main Methods:

• Conceptualization and definition of poikilosis and its implications for measurement.
• Development of a new systematics for describing measurement uncertainty and experimental designs.
• Methodology for measuring 'lagom' (normal variation) and non-lagom effects of poikilosis.

Main Results:

• Poikilosis necessitates a shift from single-point measurements to interval-based considerations.
• A novel framework for poikilosis-aware experimentation, data analysis, and interpretation is presented.
• New systematic approaches for uncertainty description and experimental design classification are introduced.

Conclusions:

• Accounting for poikilosis is essential for accurate scientific measurement and understanding.
• Poikilosis-aware methodologies can resolve long-standing scientific controversies and enigmas.
• Adopting these new approaches will significantly improve the reproducibility of scientific studies and measurements.
