Synthese has just published one of my papers on implicit bias. As with all of my papers, you can find a link to the free preprint on my CV: byrdnick.com/cv. The final, corrected, and typeset version is on Synthese’s website and the audio version is on my podcast. In this post, you will find a non-technical overview of the paper’s main point and then the TLDR explainer.

1. A Non-technical Overview

The first paragraph of the paper basically lays out an analogy of my main objection to the arguments that I am responding to. So, I’ll just include that excerpt below.

Imagine nutrition scientists discover that bodyweight can be changed not only by calorie ingestion and consumption, but by other factors. When science columnists catch wind of these findings, they write up pieces with titles like “Why Calories Don’t Matter”, arguing that gaining and losing weight is not predicated on “any” caloric processes. Some columnists go as far as to recommend that the received, thermodynamic view of bodyweight be abandoned. Obviously, the science columnists’ conclusions do not follow. The scientists did not demonstrate that changes in bodyweight are not predicated on any caloric processes. Rather, the scientists demonstrated that some weight changes are not predicated on “only” caloric processes. That finding is consistent with the idea that bodyweight is predicated on caloric processes, even if not fully. This paper cautions against the science columnists’ any-only mix-up when thinking about implicit bias: the mistake of concluding that implicit bias is not predicated on any instances of a particular process when the evidence merely shows that implicit bias is not predicated on only instances of that particular process.

2. The TLDR explainer

Implicit biases are biases in behavior that are measured indirectly. So, for example, implicit race bias might be measured by observing how people sort pictures of White faces vs. Black faces or how close people sit to a White person vs. a Black person. In contrast, explicit race bias would be measured directly—for example, by asking people, “Do you prefer White people?” It is common to find implicit pro-White biases that are not explicitly endorsed or even explicitly disavowed. For example, someone might show more suspicion of Black people than White people even though that someone is a civil rights activist.

The good news is that there seem to be ways to reduce implicit biases—even if only temporarily. By understanding how implicit biases are changed, we learn something about how implicit biases work. Alas, it is easy to make empirical and philosophical mistakes when drawing these inferences from debiasing experiments. For example:

Overestimating the evidential value of a psychological experiment.

the evidential value of a psychological experiment. The any-only mixup: citing evidence that something is not predicated on only certain stuff, but concluding that it is not predicated on any of that stuff.

However, when we avoid those mistakes, we find strong evidence that implicit bias changes via associative manipulations that are more or less reflective. So, we can infer that implicit bias is probably associative and more or less reflective (i.e., associationism about implicit bias)—contrary to the received view of implicit bias as well as its non-associationist contenders (see Table 2).

If future (or overlooked) strong evidence suggests otherwise, then associationism and non-associationism about implicit bias are probably false and interactionism about implicit bias should take their place (see 3c, 3d, 3e, or 3f in Figure 3).

You might be asking, “What does he mean by ‘reflective’ and ‘associative’?” That’d be a good question. Explication below.
