What are the major approaches to intersectionality?
In studying the influence of identity on attitudes and behavior, there are two major approaches to intersectionality, with some important internal divisions.
One is a unitary, or additive, approach, and the other can be called the multiplicative approach. I present the essence of these approaches to intersectionality.
Unitary, or Additive, Approach to Intersectionality
Most researchers employ the unitary approach. Its main theoretical assumptions are that:
(a) demographic categories have social properties that are distinct from the other characteristics of individuals,
(b) a separate category could be a the best predictor of the dependent variable (Hancock 2007; Weldon 2006).
In the unitary approach, it is assumed that demographic variables have additive effects. For example, the joint effect of being a woman, belonging to an ethnic minority, and representing disadvantaged social class are a sum of the effects of these three demographic variables.
Multiplicative Approach to Intersectionality
Multiplicative approach is also called categorical (McCall 2005). In intersectionality theory, the influence of demographics on a social outcome is conditional on the intersections of the demographic categories. This approach suggests interaction terms of categories that identify respondent groups.
In a relaxed version of intersectionality theory, the constituent elements of intersections have valid social meaning. Moreover, this approach “begins with an analysis of the elements [of the intersections] first because each of these is a sizable project in its own right” (McCall 2005: 1787). The constituent elements of intersections are there to provide context for the intersections themselves (Weldon 2006).
Versions of intersectionality theory range from more relaxed to more strict
In the strictest version, it is assumed that “social life is considered too irreducibly complex… to make fixed categories anything but simplifying social fictions…” (McCall 2005: 1773). Gender, ethnicity, and class are inseparable as each has no valid social meaning on their own. This “anticategorical” approach assumes that each constituent category of the intersection has no autonomous effects (McCall 2005; Weldon 2006: 240).

As researchers use various names for these approaches, I chose names based on what I considered the most intellectually appealing. For unitary, I use Hancock’s 2007 term, and Weldon (2006: 240) suggests the term “monism” for this concept. For variants of intersectionality, I refer to Leslie McCall’s (2005) terms: anticategorical, intracategorical and intercategorical, the last reduced to “categorical approach,” which I refer to as the multiplicative approach, as multiplicative interaction terms are the key element. Anticategorical and intracategorical have nuances that separate them, but the differences are not sufficiently pronounced to suggest fundamentally different statistical approaches. Weldon (2006) refers to McCall’s anticategorical and intracategorical as the Intersectionality-Only model and the categorical approach as the Separable-But-Mutually-Reinforcing model.
