Although the theory that creativity requires blind variation and selective retention (BVSR) is now more than a half-century old, only recently has BVSR theory undergone appreciable conceptual development, including formal three-parameter deﬁnitions of both creativity and sightedness. In this article, these new developments are for the ﬁrst time extended to encompass sequential BVSR, that is, when ideas are generated and tested consecutively rather than simultaneously. Formulated in terms of creative problem solving, sequential BVSR is shown to have two forms: (a) exploratory in which the person decreases total ignorance and (b) eliminatory in which the person vets informed guesses. Only in the latter case does sightedness for both single potential solutions and the set of potential solutions necessarily increase with each generation-and-test trial. Exploratory BVSR is illustrated by Edison’s search for a practical incandescent ﬁlament, whereas eliminatory BVSR is exempliﬁed by Watson’s discovery of the DNA base code. Hence, although epistemologically and psychologically distinct, both represent important forms of creative problem solving. © 2013 Elsevier Ltd. All rights reserved.

1. Introduction More than a half-century ago Donald T. Campbell (1960) argued for a single generic process that could account for creative thought and “other knowledge processes” (p. 380), namely, blind variation and selective retention, or BVSR (Simonton, 2011b). The basic idea is that the only way to ﬁnd out something truly new—whether a discovery, invention, or adaptation—is to engage in some kind of trial-and-error or generation-and-test procedure. In contrast, if the ideas or responses are already known to work in advance, then the person has merely engaged in reproductive rather than productive thinking, conﬁrming what is previously known rather than venturing into the unknown. Regrettably, Campbell did not precisely deﬁne the central terms of his theory (Simonton, 2011b, in press). In particular, he failed to deﬁne either what it meant for an idea to be “blind” or what it signiﬁed to be “creative.” This failure led to unnecessary controversy because neither proponents nor opponents were using the key concepts in the same way (Simonton, 2011c). Recently, I have attempted to remedy this regrettable problem by introducing new formal deﬁnitions, computer simulations, empirical inquiries, case studies, and mathematical models (e.g., Damian & Simonton, 2011; Simonton, 2007, 2010, 2012a, 2012c, 2012d, in press). Three of these new developments are of special importance to the present article. First, the key terms have been deﬁned as quantitative variables rather than qualitative attributes (Simonton, 2012d, in press). Hence, rather than talk about whether an idea is creative or not and blind or not—yielding an artiﬁcial 2 by 2 table of just 4 possibilities—the discussion shifts to relative degrees of creativity and blindness. In fact, blindness is conceived as just one end of a continuous blind-sighted spectrum (Simonton, 2011a, in press). This more
