In late 2025, artificial intelligence companies like OpenAI popularized the idea of automating the process of selecting which model is best for a task. This allowed users to simply send their prompt or request and let the system determine whether to respond using a "fast" or a "slow" reasoning model.



In a 2022 paper, I suggested that this kind of strategic deployment of slow, more reflective reasoning could be crucial to good judgment and decision-making. This year I am fleshing out the argument for this view in a paper titled, "Strategic Reflectivism in Intelligent Systems".



In this episode, I'll read the paper, which argues that one key to intelligence in humans and machines is pragmatic switching between intuitive and reflective thinking based on the goals of the system. The paper has a wide range of implications for applied science, computer science, decision science, and epistemology.

You may have heard me drone on and on about this thing called "reflective thinking". We philosophers and cognitive scientists are preoccupied with it. However, the term 'reflection' is sometimes used in different ways by scholars. To unify, make sense of, and guide our research, I synthesized a unified account from hundreds of years of English language, from philosophers, and from cognitive science. The result is this paper.



In this episode, I'll read the paper, which explains the two key features of 'reflection' and how we measure them. This two-factor account of reflective thinking has implications for theories of rationality, self-knowledge, and dual-process theories.

You may have heard that atheists tend to score better on reflection tests than theists? But why do scientists find this "analytic atheism" correlation?



Many studies have attempted to answer this question. Of course, even the best studies had limitations. So Steve Stich, Justin Sytsma, and I developed better methods and studied over 70,000 people on 6 continents. What did we find?



Apostasy was key. Those who shed their religion since childhood were the most reflective. Lifelong atheists were not necessarily more reflective than theists. In other words, the analytic atheism correlation seems to be explained by analytic apostasy.



In this episode, I'll explain the methods, results, and implications in our paper "Analytic Atheism & Analytic Apostasy Across Cultures" which will be published in Religious Studies.

Suppose you glance at a clock that, unbeknownst to you, is broken, showing the same time all day. Nonetheless, you happened to look at the clock precisely when it showed the correct time. So your belief about the time is correct. My question is this: did you know what time it is?



Perhaps you think that you did. After all, you formed a belief on the basis of a device that most people trust and the belief was true! What else would it mean to know something? Well, in academic philosophy, the orthodox answer to this kind of thought experiment is "no".



People who perform better on tests of reflective thinking tend to report philosophers' orthodox answer to this kind of thought experiment. And, if you've been following my research, you know that philosophers are particularly reflective thinkers. These correlations may make you wonder about causation. Does thinking reflectively cause people to accept philosophers' orthodoxy? Or is it the other way around: does studying thought experiments like the broken clock case somehow result in people performing better on reflection tests?



In this episode, I'll tell you about the experiment I ran to find out. The paper is titled "Reflection-Philosophy Order Effects and Correlations Across Samples" and has been accepted for publication in Analysis. The paper will also mention a bunch of other thought experiments, tests of reflective thinking, and measures of research participants' data quality.

I have a question for you: "If a bat and a ball cost $1.10 in total and the bat costs $1.00 more than the ball, how much does the ball cost?". Did 10 cents seem right? The authors of questions like this are attempting to lure you to accept this incorrect answer in order to test whether you thought reflectively when you solved the problem. However, there may be problems with this method of testing reflective thinking. So my colleagues used some underrated methods to determine the degree to which tests like this misclassify correct responses as reflective or lured responses as unreflective. I'll read the paper in this episode.

In this episode, I read my short paper with Morgan Thompson in WIRES Cognitive Science titled, "Testing for Implicit Bias: Values, Psychometrics, and Science Communication". You may have heard about implicit bias. It is measured by indirect rather than direct measures of bias. We reconstruct arguments from debates about these measures, reveal some instances of talking past one another, highlight how debate has changed, and highlight how the debate is laden with value judgments about psychometrics and science communication.

This time I read my 2022 paper in Review of Philosophy and Psychology titled, "Great Minds Do Not Think Alike: Philosophers' Views Predicted by Reflection, Education, Personality, and Other Demographic Differences". As the title suggests, various psychological factors predicted variance in philosophers' answers to classic philosophical questions. This raises questions about how psychological and demographic differences can explain philosophical differences. There are also implications for scientific psychologists as well as academic philosophers.

In this episode, I read one of my 2022 articles in Metaphilosophy titled, "Bounded Reflectivism & Epistemic Identity". Does reflective reasoning help or hinder our judgment? In this paper, I take a middle view between reflectivism and anti-reflectivism that I call bounded reflectivism. The idea is that reflection is a tool that can be used to improve our judgment or for other purposes (such as to defend the beliefs that we consider essential to our identity—a.k.a., our "epistemic identity").

Welcome to the latest episode of Upon Reflection. This time, I read my paper with Michał Białek, "Your health vs. my liberty: Philosophical beliefs dominated reflection and identifiable victim effects when predicting public health recommendation compliance during the COVID-19 pandemic" (Total N = 998).



As the title suggests we found that complying with public health recommendations didn't depend on whether people received messaging about identifiable COVID-19 victims or statistical victims in flatten the curve graphs. Rather compliance increased the more that people endorsed an effective altruist principle about reducing harm and the more that they endorsed the truth of scientific theories, but compliance decreased as people valued liberty more than equality. Importantly, we also found that people were less likely to prevent the spread of disease by wearing masks and staying at home if the pandemic was equally deadly, but labeled as a "flu" pandemic—-mostly because they perceived this as less threatening to society. We think this suggests that people's life-threatening decisions to flout public health recommendations like mask-wearing and staying at home during the COVID-19 pandemic was not just about ineffective messaging, but also about their prior philosophical commitments.

In this podcast I'll be sharing my own and others' research with you. For instance, I'll talk about the differences between intuition and reflection and how intuitive reasoning predicts different philosophical beliefs than reflective reasoning. I'll also discuss topics like implicit bias and how—contrary to what you may have heard—implicit bias may not be entirely unconscious and involuntary. Of course, cognitive science is an interdisciplinary research community. So there will be much more to talk about.
