Kurzfassung. The quantitative revolution in the field of geography is commonly recalled as a story of scientific success, overcoming parochial, regionalist and ideographic modes of geography. This paper, however, suggests a different, yet parallel narrative. It reveals that the methodological reorientation towards statistical geography was a coping strategy, adopted by researchers from within and outside the discipline of geography in order to defend the analysis of ecological (i. e., spatially aggregated) data against the powerful critique of producing "ecological fallacies". Through emphasizing how the quantitative revolution was an expression of both modernizing and protective tendencies within the field of geography, the paper contributes to a more concrete understanding of what motivates methodological change in geography.
