Christopher Peacocke’s The Mirror of the World (2014) is largely about self-consciousness. In the book, Peacocke distinguishes “reflective” self-consciousness from other kinds of self-consciousness. In this post, I will try to understand what Peacocke means by ‘reflective’. Spoiler: it is not what I and many other philosphers mean by ‘reflective’.

My Experience with Christian Apologetics
I took a few courses in biblical studies and Christian apologetics as an undergraduate. The courses definitely influenced my thinking, but not in the way that I expected.
0. Context
For years, I intended to study engineering. In my senior year of high school, I was admitted to a public school with a decent engineering program. But late in the summer, I changed my mind. I had recently become a Christian and I was dating someone who was going to a Christian college. And apparently that was enough to convince 18-year-old-me that I should also go to a Christian college and study the Bible. (Aside: Can you believe that 18-year-old-me was allowed to vote and serve on a jury?)
1. Apologetics
I signed up for Christian apologetics courses — as well as biblical studies courses — hoping to find compelling arguments to rationalize my relatively new faith. At first, the arguments seemed compelling. I remember being excited to take the arguments to unbelieving friends back home and see what they had to say.
But the more I thought about the arguments, the less Continue reading My Experience with Christian Apologetics
Are Atheists More Reflective Than Theists?
On Saturday, I was on the Veracity Hill Podcast talking about the evidence that atheists and agnostics reason more reflectively (i.e., make fewer errors) than theists.
The Discussion
- What do we mean by ‘reflective’? And how do we measure reflection? Who counts as a theist? And how do we measure religiosity?
- What do these findings about atheists and theists tell us about atheism and theism (if anything)? And how might further research answer hitherto unanswered questions about how atheists and theists reason?
- What are some related findings? For instance, what does this have to do with other philosophical beliefs?

What Is Reflective Reasoning?
Last week I was talking about intuition. I think of intuition as — among other things — unconscious and automatic reasoning. The opposite of that would be conscious and deliberative reasoning. We might call that reflective reasoning.† In this post, I want to talk about reflective reasoning. How does it work? And why does it work? And — spoiler alert — why does it sometimes not work?

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.
Experimental Philosophy 2.0: The Neuroscience of Philosophy
If our judgments are dependent on the brain, then maybe we can understand our judgments by studying our brains. Further, maybe we can understand our philosophical judgments by studying our brains. What do you think? Can neuroscience help us understand philosophy? Here are some studies which suggest that it can.
1. Two Opposing Neural Networks/Judgments
Consider two different networks in the brain: the Default Mode Network (DMN) and the Task Positive Network (TPN). These networks are mutually inhibitory. When one network’s activity increases, the other network’s activity decreases. It’s a bit like a seesaw (Jack et al 2013).

The Bias Fallacy
“They’re biased, so they’re wrong!” That’s a fallacy. We can call it the bias fallacy. Here’s why it’s a fallacy: being biased doesn’t entail being wrong. So when someone jumps from the observation that So-and-so is biased to the conclusion that So-and-so is wrong, they commit the bias fallacy. It’s that simple.
In this post, I’ll give some examples of the fallacy, explain the fallacy, and then suggest how we should respond to the bias fallacy.
1. Examples of The Bias Fallacy
You’ve probably seen instances of the bias fallacy all over the internet.
In my experience, the fallacy is a rhetorical device. The purpose of the bias fallacy is to dismiss some person or their claims.
Like many rhetorical devices, this one is logically fallacious. So it’s ineffective. At least, it should be ineffective. That is, we should not be persuaded by it.
So if you’ve seen the bias fallacy online, then go ahead and set the record straight:
'They're biased, so they're wrong.' Not so fast! We can be biased without being wrong. #TheBiasFallacyClick To Tweet Continue reading The Bias Fallacy
A Definition of ‘Fake News’ (and Related Terms)
If the public discourse in the United States is any indication, then people in the US mean different things by ‘fake news’. Naturally, then, it is time to agree on a definition of ‘fake news’. While we’re at it, let’s distinguish ‘fake news’ from other terms.
Any negative polls are fake news, just like the CNN, ABC, NBC polls in the election. Sorry, people want border security and extreme vetting.

1. Let’s Agree On Terms
As I see it, we will need to distinguish between at least three terms: fake news, conspiracy theory, and journalism.
A Definition of ‘Fake News’
Also known as “fictional news”. Characterized by outlandish stories — sometimes about paranormal and supernatural events. Any explicit claims to truth are obviously belied by their only semi-serious and comedic tone. Examples include many of the cover stories of the Weekly World News as well as some of the satirical punchlines of The Daily Show.
A Definition of ‘Conspiracy Theory’
Bad explanations designed to glorify their author and undermine the author’s perceived nemeses. Sometimes unfalsifiable. Alas, believed by many people. Examples are voluminous. Examples include certain explanations of the assignation of John F. Kennedy and InfoWars’ Alex Jones’s claims that the Sandy Hook shootings were staged.
A Definition of ‘Journalism’

Research Questions & Mental Shortcuts: A Warning
Daniel Kahneman talks extensively about how we make reasoning errors because we tend to use mental shortcuts. One mental shortcut is ‘substitution‘. Substitution is what we do when we (often unconsciously) answer an easier question than the one being asked. I find that I sometimes do this in my own research. For instance, when I set out to answer the question, “How can X be rational?” I sometimes end up answering easier questions like, “How does X work?”. In an effort to avoid such mistakes, I will (1) explain the question substitution error, (2) give an example of how we can distinguish between questions, (3) give a personal example of the substitution error, and (4) say what we can do about it.
1. Substitution
In case you’re not familiar with Kahnemen’s notion of ‘substitution’, here is some clarification. In short, substitution is this: responding to a difficult question by (often unintentionally) answering a different, easier question. People use this mental shortcut all the time. Here are some everyday instances:
| Difficult Question | Easier Question |
|---|---|
| How satisfied are you with your life? | What is my mood right now? |
| Should I believe what my parents believe? | Can I believe what my parents believe? |
| What are the merits/demerits of that woman who is running for president? | What do I remember people in my community saying about that woman? |
For further discussion of mental shortcuts and substitution, see Part 1 of Kahneman’s Thinking Fast and Slow (2012).
Now, how does this mental shortcut apply to research? Continue reading Research Questions & Mental Shortcuts: A Warning
Crystal Meth & Your Brain: An Infographic
Methamphetamine use is on the rise (Drug Enforcement Administration 2015). And so are crystal-meth-related drug convictions (see “State Sentencing…”). So what do we know about crystal meth? In particular, what does crystal meth do to your body and brain? The South Shore Recovery Center has some answers. In fact, they’ve done us the favor of turning those answers into the infographic below.
