The Appeal to Intuition: A Fallacy?


You might be familiar with what philosophers call an “appeal to nature“. It is a claim that something is good or bad because of how natural it is. Sometimes an appeal to nature is a fallacy. In this post, I discuss the possibility that an appeal to intuition is that kind of fallacy.

Implicit Bias & Philosophy


This week, I’m talking about implicit bias over at The Brains Blog. I’m including my portion of the discussion below.

1.  The Implicit Association Test (IAT)

The implicit association test (IAT) is one way to measure implicitly biased behavior. In the IAT, “participants […] are asked to rapidly categorize two [kinds of stimuli] (black vs. white [faces]) [into one of] two attributes (‘good’ vs. ‘bad’). Differences in response latency (and sometimes differences in error-rates) are then treated as a measure of the association between the target [stimuli] and the target attribute” (Huebner 2016). Likewise, changes in response latencies and error-rates resulting from experimental interventions are treated as experimentally manipulated changes in associations.

2.  The Effect Of Philosophy

As philosophers, we are in the business of arguments and their propositions, not associations. So we might wonder whether we can use arguments to intervene on our implicitly biased behavior. And it turns out that we can — even if the findings are not always significant and the effect sizes are often small. Some think that this effect of arguments on IAT performance falsifies the idea that implicitly biased behavior is realized by associations (Mandelbaum 2015). The idea is that propositions are fundamentally different than associations. So associations cannot be modified by propositions. So if an arguments’ propositions can change participants’ implicitly biased behavior — as measured by the IAT — then implicit biases might “not [be] predicated on [associations] but [rather] unconscious propositionally structured beliefs” (Mandelbaum 2015, bracketed text and italics added). But there is some reason to think that such falsification relies on oversimplification. After all, there are many processes involved in our behavior — implicitly biased or otherwise. So there are many processes that need to be accounted for when trying to measure the effect of an intervention on our implicitly biased behavior — e.g., participants’ concern about discrimination, their motivation to respond without prejudice (Plant & Devine, 1998), and their personal awareness of bias. So what happens when we control for these variables? In many cases, we find that argument-like interventions on implicitly biased behavior are actually explained by changes in participants’ concern(s), motivation(s), and/or awareness, but not changes in associations (Devine, Forscher, Austin, and Cox 2013; Conrey, Sherman, Gawronski, Hugenberg, and Groom 2005).

Is Reflective Reasoning Supposed To Change Your Mind?


When you step back and question your beliefs and assumptions, do you expect to change your mind? Should you? I think that reflective reasoning is supposed to change our minds. But it might not change our beliefs. Sometimes reflection reinforces our beliefs. And sometimes reflection makes our beliefs more extreme or partisan. I’ll explain below.

Considering Third Party Candidates? A Podcast Discussion


The 2016 US election has many people thinking about third party candidates. Good news: philosophers and others have been sorting out the ethics and rationality of voting for awhile now. I talk about the philosophy of third party voting with Kurt Jaros below:

Fact-checking is not enough. We need argument-checking.


I see more fact-checking on Facebook than I used to. While I’m glad to see fact-checking catching on, fact-checking isn’t enough — or so I’ll argue in this post.

1. Fact-checking: The problem

Let’s say that you and I agree on all the facts. Now let’s say that we start arguing. Will we argue well? Not necessarily!

After all, we can reason badly even if we agree on the facts. Specifically, we can jump to conclusions that don’t follow from the facts. So fact-checking our argument(s) won’t necessarily fix all the problems with our argument(s).

2. Bad Arguments

Consider some of the claims that people make:
