Upon Reflection, Ep. 13: Reflection-Philosophy Order Effects and Correlations Across Samples

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.

The Bat And Ball Problem 20 Years Later

In 2002, a chapter from Kahneman and Frederick mentioned “the bat and ball problem”.

A bat and a ball cost $1.10 in total.
The bat costs $1.00 more than the ball.
How much does the ball cost?

By 2005, Frederick’s Cognitive Reflection Test paper added the lesser known Widgets and Lily Pad problems. In the intervening 20-ish years, each paper seems to have accrued over 5000 citations.

In 2023, Meyer and Frederick published a massive follow-up paper about the first problem: 59 studies, over 73,000 participants, and more pages of Appendixes than pages in the main article. As someone studying various reflection tests and interventions, I had to take a look right away. In this post, I list five initial takeaways and two things to like about the paper.

Upon Reflection, Ep. 10: Great Minds Do Not Think Alike

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.

Non-Western Philosophy of Mind

I have been considering changes to my Philosophy of Mind syllabus. One kind of change would be to include non-Western philosophies and philosophers. So I did what every scholar of our era does when it’s time to venture in to new territory: I asked #PhilosophyTwitter. In this post, I’ll share the results.

Upon Reflection, Ep. 7: Unreflective Intentions Are Compatible With Free Will

On this episode of Upon Reflection, I read my 2021 paper in Logoi titled, “On Second Thought, Libet-style Unreflective Intentions May Be Compatible With Free Wil l“. Imagine if I could predict your behavior before you even became conscious of your intention to behave that way. Would this mean that you don’t have free will? I used to think so. In this paper, I explain why I was wrong: my view of free will involved magical thinking.

What good is reflective reasoning?

Philosophers and cognitive scientists tend to think that reflective reasoning will improve our judgments and decisions. The idea reflection will lead us to test our judgments by “looking for their coherence with our beliefs about similar cases and our beliefs about a broader range of …issues” a la reflective equilibrium. This sounds intuitively plausible. But is it true? In this post I briefly present some research suggesting that reflective reasoning often, but does not always improve our judgments and decisions. Continue reading What good is reflective reasoning?

Upon Reflection, Ep. 5: Reflective Reasoning For Real People (Dissertation Overview)

Welcome to Upon Reflection. In this episode, I review the major take-aways and findings from my dissertation titled, “Reflective Reasoning For Real People”. I explain what cognitive scientists mean by terms like “reflective reasoning”, how reflection is measured empirically, how reflection can either help or hinder our reasoning, how more reflective philosophers tend toward certain philosophical beliefs, and how reflection may help us retrain our implicit biases.

Anders Ericsson (1947-2020)

My colleagues and I are deeply saddened about the unexpected passing of Anders Ericsson on June 17. Dr. Ericsson was not only a massive figure in psychology, philosophy, performance, and beyond but—in my experience—an outstanding person.

Standout Memories

There is much to say about Anders. I can speak only to the past few years—and only a slice of it. Nonetheless, that slice of Anders is rich. Indulge me in just three stories.

On Whether Reflection Is A Skill

In my last post, I considered whether reflective reasoning is a virtue. One possibility was that reflection cannot be a virtue. However, if reflection is not a virtue, then we need another account of why many people value reflection. One such account might be that reflection is a skill. In this post, I’ll briefly consider some reasons for and against thinking that reflection is a skill.

On Whether Reflection Is A Virtue

Some philosophers think of rationality in terms of virtue. For them, the rational thing to do is what the epistemically virtuous person would do. One type of reasoning that I study is reflective reasoning in which we step back and reconsider a gut reaction. So I have found myself asking, “Is reflective reasoning a virtue?” In this post, I’ll briefly consider reasons for answering “yes” and reasons for answering “no.” Continue reading On Whether Reflection Is A Virtue
