Decision Making: Nonrational Theories (2001, background): “Einhorn and Hogarth (1975) found that unit-weight models were more successful than multiple regression when the ratio of alternatives to cues was 10 or smaller, the linear predictability of the criterion was small (R2 0.5), and cues were highly redundant.”
Simple rules to guide expert classifications (2020, methodology): “In this work, we generalize from research on improper linear models (Einhorn and Hogarth, 1975; Green, 1977; Dawes, 1979; Gigerenzer and Goldstein, 1996; Waller and Jones, 2011) to suggest a straightforward method for constructing simple yet accurate decision rules that experts can apply mentally.”
Why recognition is rational: Optimality results on single-variable decision rules (2010, background): “Davis-Stober et al. (2010) provide an analysis of (5) for several well-known choices of a, including: equal weights (Dawes, 1979), weighting a subset of cues while ignoring others, and unit weighting (Einhorn & Hogarth, 1975).”
Reasoning the fast and frugal way: models of bounded rationality. (1996, methodology): “ Einhorn and Hogarth (1975) noted that in the unit-weight model “there is essentially no estimation involved in its use” (p. 177), except for the sign of the unit weight.”
Using advice from multiple sources to revise and improve judgments (2007, background): “Research on judgment analysis has pointed out that simple models of judgment (of the sort used here) are rarely surpassed by more complex ones (Einhorn & Hogarth, 1975).”
Bailing and jailing the fast and frugal way (2001, unknown): “…both models are excellent approximations to regression models in terms of descriptive and predictive validity (Dawes and Corrigan, 1974; Cattin, 1978; Dorans and Drasgow, 1978; Einhorn and Hogarth, 1975; Gigerenzer et al., 1998; 1999; Gigerenzer and Goldstein, 1996; Schmidt, 1971; Wainer, 1976).”
Advice Taking in Decision Making: Egocentric Discounting and Reputation Formation. (2000, methodology): “Indeed, simple averaging has been the most frequent combination scheme in the studies cited above, so it will be used as a reference in discussing the weighting policies that respondents use (Dawes, 1979; Einhorn & Hogarth, 1975; Harvey & Fischer, 1997).”
The conceptualization and empirical validation of web site user satisfaction (2004, methodology): “Simple unit weighting, rather than weighting in function of the path coefficients, was used for forming composite scores [35].”
Illusions in Regression Analysis (2012, unknown): “Einhorn and Hogarth (1975) and Dana and Dawes (2004) show the conditions under which regression is and is not effective relative to equal weights.”
