Donald T. Campbell
Donald Thomas Campbell (November 20, 1916 – May 5, 1996) was an American social scientist. He is noted for his work in methodology. He coined the term "evolutionary epistemology" and developed a selectionist theory of human creativity.
Campbell was born in 1916, and completed his undergraduate education in psychology at the University of California, Berkeley, where he and his younger sister, Fayette, graduated first and second in the class of 1939.
After serving in the U.S. Naval Reserve during World War II, he earned his doctorate in psychology in 1947 from UC Berkeley. He subsequently served on the faculties at Ohio State, the University of Chicago, Northwestern, and Lehigh.
He taught at Lehigh University, which established the Donald T. Campbell Social Science Research Prizes. Prior to that he was on the faculty of Maxwell School of Syracuse University, 1979–1982, and Northwestern University from 1953 to 1979. He gave the William James Lecture at Harvard University in 1977.
Campbell was elected to the National Academy of Sciences in 1973. In 1975, Campbell served as President of the American Psychological Association.
Among his other honors, he received the American Psychological Association’s Distinguished Scientific Contribution award, the Distinguished Contribution to Research in Education award from the American Educational Research Association, and honorary degrees from the Universities of Michigan, Florida, Chicago, and Southern California.
He had as a major focus throughout his career the study of false knowledge -- the biases and prejudices that poison everything from race relations to academic disciplines where those with vested interests in them perpetuate erroneous theories.
Convergent and discriminant validation by the multitrait-multimethod matrix 
Dr. Campbell argued that the sophisticated use of many approaches, each with its own distinct but measurable flaws, was required to design reliable research projects. The paper he wrote with Donald W. Fiske to present this thesis, "Convergent and Discriminant Validation by the Multitrait-Multimethod Matrix," is one of the most frequently cited papers in the social science literature.
Blind variation and selective retention 
Blind variation and selective retention (BVSR) is a phrase introduced by Donald T. Campbell to describe the most fundamental principle underlying Darwinian evolution. In cybernetics, it is seen as a principle for describing change in evolutionary systems in general, not just in biological organisms. For example, it can also be applied to scientific discovery, memetic evolution or genetic programming. As such, it forms a foundation for what has later been called Universal Darwinism.
Evolutionary epistemology 
Applying the BVSR principle to the evolution of knowledge, Campbell founded the domain of evolutionary epistemology. This can be seen as a generalization of Karl Popper's philosophy of science, which conceives the development of new theories as a process of proposing conjectures (blind variation) followed by the refutation (selective elimination) of those conjectures that are empirically falsified. Campbell added that the same logic of blind variation and selective elimination/retention underlies all knowledge processes, not only scientific ones. Thus, the BVSR mechanism explains creativity, but also the evolution of instinctive knowledge, and of our cognitive abilities in general.
"The Experimenting Society" 
Campbell also had a vision for how public policy could be improved through use of experimentation. He argued for a more collaborative method of public policy that involved various stakeholders and that used experimentation and data as a guide for decision making. The vision of this was laid out in an essay The Experimenting Society.
His research and book Experimental and Quasi-Experimental Designs for Research became the standard in policy evaluation circles. Campbell did not start out intending to be a program evaluator, but as described in Donald Campbell: The Accidental Evaluator, his devotion to understanding causality, human behavior, and how to solve social questions led him there.
"Ethnocentrism of Disciplines and the Fish-Scale Model of Omniscience" 
Campbell was a wide, wide collaborator and distrustful of academic knowledge of any field whose knowledge resided in small clusters separated from other fields. To parody this situation, he wrote an article on the "Fish-Scale Model of Omniscience" which called for scholars to stray from their immediate discipline and work to create bridges (or fish scales!) between their disclipine and neighboring ones.
"Rather than praying, “May I be a competent and well-read X-ologist, may I keep up with the literature in my field,” a scholar will pray, “Make me a novel fish-scale. Let my pattern of inevitably incomplete competence cover areas neglected by others.” Each scholar would then try to have a pattern of journal subscriptions unique to his or her department, university, or profession. Noting that the scholar and a colleague were reading the same set of journals, the scholar would feel guilty and vow to drop one of these in favor of some other. Recognizing that the interdisciplinary links in the collaborative web of knowledge are the weakest, the scholar would give up some ingroup journal in favor of an outgroup one. The scholar would feel guilty if he or she did not cut attendance at ingroup conventions to attend relevant outgroup ones, and so forth."
Further development of Campbell's ideas 
In the 1990s, Campbell's formulation of the mechanism of "blind-variation-and-selective-retention" (BVSR) was further developed and extended to other domains under the labels of "universal selection theory" or "universal selectionism" by his disciples Gary Cziko, Mark Bickhard, and Francis Heylighen.
