The normative structure of mathematization in systematic biology

Area of Science:

• Systematic biology
• Philosophy of science

Background:

• The mathematization of science is often viewed as a neutral process.
• Understanding mathematization as a normative activity provides new insights into scientific methodology.

Observation:

• This study examines the mathematization of taxonomic classification in systematic biology.
• It contrasts Ernst Mayr's qualitative formalism (1940s) with numerical taxonomy's quantitative formalism (1960s).
• Both approaches aimed to formalize classification but differed in their reliance on human judgment versus automated procedures.

Findings:

• Mathematization is a normative activity, advocating for specific research methodologies and evaluation criteria.
• Mayr's approach prioritized human judgment in determining taxonomic rank.
• Numerical taxonomy utilized automated procedures for classification, emphasizing quantitative methods.

Implications:

• Contrasting these formalisms reveals differing conceptualizations of the classification workflow.
• The study highlights the importance of meta-level discourse in addressing challenges within scientific classification.
• This analysis enriches the understanding of how mathematical methods shape scientific research and evaluation.
