Structural Falsification, Scientific Silence, and a New Research Strategy: A Critical Reconstruction of the Hector’s and Māui Dolphin Case

Abstract

This paper examines the decline of Hector’s and Māui dolphins in New Zealand not only as an ecological problem but also as a methodological problem concerning the organisation of scientific knowledge. The study is motivated by the public release of the previously unavailable Groundwater Technology technical reports (1995–1996), which substantially expand the evidentiary basis for evaluating the chemical pollution hypothesis. Although these reports do not demonstrate that chemical contamination was the principal cause of population decline, they provide important information on historical contamination sources, groundwater, chlorophenols, phenoxy compounds, pesticides, solvents, contaminant transport pathways, environmental modelling.

The paper argues that the emergence of these documents changes the structure of scientific inquiry. The central question is no longer whether the chemical hypothesis should replace competing explanations such as fisheries-related mortality, demographic vulnerability, infectious disease, or habitat change. Rather, the key issue is why evidence capable of substantially modifying the research programme remained outside active scientific analysis for almost three decades.

To address this problem, the study employs a framework of critical reconstruction that examines both environmental processes and the organisation of scientific knowledge. Particular attention is given to structural falsification, understood as the long-term exclusion of significant evidence from recognised scientific knowledge.
