Abstract Details

2017, Doctor of Philosophy, Ohio State University, Psychology.
Naive theories of bias have been implicated in bias correction (e.g., Petty & Wegener, 1993; Strack, 1992), but little is known of the influence of qualities of those theories. The present research posits that theories of bias may vary not only in terms of perceived magnitude and direction of bias, but also in terms of bias breadth or generality: perceived biases may vary in the extent to which they are viewed as applicable to many or to few judgments (Wegener & Petty, 1997). A series of studies examined the impact of perceived bias breadth on bias correction. Using an estimation task based on prior research (McCaslin, Petty, & Wegener, 2010), Study 1 demonstrated that measured beliefs about the breadth of a bias predict correction, such that for targets that are less prototypical of the bias in question, greater breadth predicts greater compensation for the perceived bias. A pilot study demonstrated the manipulability of beliefs about breadth, and Study Set 2 (a series of data collections) demonstrated that manipulated breadth interacts with bias direction and target category to influence correction, such that for targets that are prototypical of a given bias, breadth does not impact correction, whereas for targets that are less prototypical, greater breadth leads to greater bias correction. Study Set 3 (also a series of data collections) showed that manipulated construal level (abstraction) can impact bias correction in a conceptually similar manner to breadth effects from Study Set 2. Taken together, these studies suggest that bias correction is determined not only by perceived direction and magnitude, but also by properties of the bias belief, such as breadth, and properties of the target of judgment.
