Neurological Effects of Religion

While writing this post, I found myself having to list detailed definitions along with caveats and careful explanations: the concepts of religion and spirituality are complex and often ill-defined, so if you aren't careful, someone will raise their hand and say "well, what about this obscure point that you didn't address?!"  So over time the post evolved from a concise, clear description of interesting neurological facts to a meandering monstrosity. The need to keep the post short, clear, and interesting is at odds with the need to be procedurally complete.

I decided to err on the side of concise clarity.  If something rubs you the wrong way, we can hash it out in the comments later.

So lets jump right in.  In this post I will describe the neurological effects of religious worship.  Note that I am no expert.  Everything about specific neurological activity comes from the books How God Changes Your Brain by Newburg and Waldman, and Why God Won't Go Away by Newburg et. al.  Everything else is mine.

The neurological effects of worship can be summarized in one sentence: we become like what we worship¹, regardless of whether what we are worshiping is real or imagined.  For example, if we worship an angry, authoritarian, punitive God, we gain a proclivity for anger and we become less capable of being understanding and compassionate.  The amygdala - the part of the brain that produces fear and anger - is strengthened.  Interestingly, when we are angry it becomes physically impossible for us to think rationally.  On this topic, Newburg and Waldman wrote

"Anger interrupts the functioning of your frontal lobes. Not only do you lose the ability to be rational, you lose the awareness that you’re acting in an irrational way. When your frontal lobes shut down, it’s impossible to listen to the other person, let alone feel empathy or compassion. Instead, you are likely to feel self- justified and self- righteous, and when that happens the communication process falls apart. Anger also releases a cascade of neurochemicals that actually destroy those parts of the brain that control emotional reactivity."

It goes without saying that we should avoid worshiping "angry" Gods - the effects are clearly destructive.  In fact, I don't think that many people would admit to following this kind of God.  Rather, I think that people worship the authoritarian, punitive type of God without realizing what they are doing.  I'll talk more about this later, because worshiping the wrong kind of God - knowingly or unknowingly - is unhealthy and destructive.

In contrast, worshiping a compassionate, loving God actively strengthens the frontal lobe and the anterior cingulate.  The frontal lobe is the reasoning center of the brain, and the anterior cingulate is the area of the brain that allows us to suppress fear and feel empathy and compassion.  Worshiping a loving God actually rewires our neural circuits so that we don't respond with anger as quickly or easily.  It also makes us more physically capable of feeling empathy, compassion, and love for others.

To be clear, the "God" that you worship isn't necessarily the same God described by your religion.  Practically speaking, your God may be more accurately defined by what you allow yourself to focus on.  For example, if you tend to focus on the "wicked" state of the world and the impending judgment of God, then you probably worship an angry God.

More generally, your God may be described by the attitude that you generally espouse when you aren't thinking about God at all.  If you are consistently pessimistic, angry, or fearful, it has the same neurological effect as worshiping an angry, authoritarian God.  In contrast, if you actively work on being understanding, compassionate, and optimistic, it has the same neurological effect as contemplating a loving, compassionate God.

The idea that worship and regular daily activity are closely related forms much of the basis for what I called "Spiritual Atheism" in the title of my last post.  The idea suggests that at least some of the neurological benefits of religion can be obtained by consciously adjusting your attitude about life.  That is, perhaps you can get the benefits of religion without using the religion at all.

There are other benefits of religious practice that I haven't talked about - reduced fear of death, deep peace and comfort, powerfully tangible joy, and direction and meaning, not to mention the social benefits of interacting in a religious community.  In my next post, I will discuss why these other benefits can also be obtained outside the context of traditional religion.

1. When I say "worship," I am referring to specific, conscious activity centered around a God figure.  This activity could be religious ritual, deep contemplation, study of religious texts, or meditation.  In this post, I will make the case that worship and daily activity are not necessarily disjoint.  They are, I think, closely connected.  But when I use the "worship" by itself, I refer specifically to God-centered activities.
