First Blog, something to think about(?) from; Willarmet, C. M., and G. A. Clark. Paradigm crisis in modern human origins research Journal of Human Evolution (1995) 29, 487-490. 1995 Any comments please see comment section of web site! Despite the considerable efforts of many well-informed investigators, however, no resolution of the controversy is in sight. We think that the slow progress to resolution of the debate can be attributed to differences in metaphysical paradigms of modern origins researchers that in turn result in a biased selection of specimens and/or variables used in analysis.
How selectively biased are researchers? An extensive literature review of published multivariate data invoked in support of "continuity" and "replacement" positions produced some dramatic results (Willamette, 1993, 1994). A total of 680 data points were collected, representing 61 variables on 55 fossils. Of these, only 72 variables on 11 fossils, or 11% of the reported database, were common to both paradigms This means that in the sample, 89% of the data collected were used by members of only one paradigm (p. 488).
Given the construal of the paradigm just outlined, theories (more accurately the hypotheses deduced from them), can only be confirmed or discomfirmed according to the tenets of the metaphysic (the construal of "reality" defined by the biases and preconceptions of the paradigm). Outside a particular paradigm, its constituent theories ("hypotheses") might appear nonsensical.
Despite assertions to the contrary (e.g. Klein, 1989), the venerable history of the debate suggests that simply acquiring more data will not help us choose between opposing paradigms. The reason is that data have no meaning or existence independent of a paradigm that defines and contextualizes them. In light of the plethora of articles and books that have appeared in the last 10 years, it is worth asking ourselves whether we are any closer to solving the question of our origins than we were a century ago. If there is a lesson to be learned from the debate, it is that students of human evolution must begin to confront the inferential basis for their knowledge claims. So far, they have not been much concerned to do so. The result is an interminable debate, now well into its second century, with no resolution in sight (p. 489-489).
NOTE and the beat goes on? This collection of quotes is aimed at exploring a long dismissed alternative. AMH |
