Is Confirmation Bias a Bad Thing?

Is Confirmation Bias a Bad Thing? November 16, 2023

Commenting on a new blog essay that I wrote while on retreat last summer, a Facebook acquaintance who is a fellow graduate of the Great Books program at St. Johnโ€™s College wrote the following.

  • Him: I donโ€™t believe in your God nor in the notion that God or any entity created the universe. The new Webb photos confirm my long-held conviction that the universe is a cold, mindless, soulless void without purpose or meaning, and that any characterization to the contrary is wishful thinking indulged in by humankind.

I had not yet looked at the spectacular images from the Webb telescope at the timeโ€”this fellowโ€™s comment prompted me to look. I was as blown away as everyone else who has seen them. But noting that he said the images confirmed something he had believed for a long time, his comment made me think about something else.

  • Me: your conviction is a choice, just as any foundational belief is.

Where do our foundational convictions come from? Do we shape them according to evidence, or do we more often pick, choose, and shape evidence to fit our already-existing convictions? I know, these sound like classroom questions (and they frequently are in my courses)โ€”but knowing the undergraduate education the commenter and I shared, I hoped for a thoughtful response. I was not disappointed.

  • Him: I choose to seek and follow the truth, based on empirical observation and wide reading. Thatโ€™s the funny thing about choosing to seek and follow the truth. It may lead you to certain beliefs, conclusions and convictions that you wish you didnโ€™t believe. Because existence would be so much more bearable and pleasant without them. But you have no choice. The truth is the truth, no matter where it leads you.
  • Him again: Also, my devotion and loyalty to the truth requires me to be open and receptive to experiences or information that might challenge, change and modify my beliefs and convictions. If it turns out that Iโ€™m wrong about God, the universe or anything else, I will cheerfully change my views and beliefs.

There is much of value in these responses, starting with a praiseworthy dedication to the pursuit of truth wherever it might lead no matter what the area of pursuit. Commitment to actually changing oneโ€™s mind concerning what is and is not true on the basis empirical observation and wide reading is similarly praiseworthy.

But such a pursuit never happens in a vacuum. In my conversations with atheists over the years, I have found that their most frequent criticism of persons of faith is that such people always start with a belief in place, then seek to fit selected data into that belief framework, warping some data and fully ignoring other data if they donโ€™t fit preconceptions. My response is not to claim that, on the contrary, faith is โ€œobjectiveโ€โ€”it is anything but. My response is rather that there is no such thing as an โ€œobjectiveโ€ observerโ€”the pursuit of truth and the building of a belief system is much more complicated (and interesting) than that. That applies equally to persons of faith, atheists, and every other human being.

  • Me:ย There are many truths I believe in that I wish were otherwise. My comment is not about truth, though. Itโ€™s about confirmation bias. You see the Webb photos and they confirm something that is a โ€œlong-held conviction.โ€ No surprise there. Another person looks at precisely the same photos and finds that they confirm their belief in an awesome and powerful creating God. No surprise there either.

How is it that two people of good faith, looking at and considering the very same new data, can conclude that the new data confirms โ€œlong held convictionsโ€ that happen to be entirely contradictory? The answer at least partially lies in realizing that no one is exclusively, or even primarily, data driven. With apologies to John Locke, no one is a tabula rasa, a blank slate. What even counts as a fact or as truth is shaped by belief frameworks that often reflect experiences that we may not even be aware of.

Just to be clear, I am one of those people who look at the Webb images and find that they immediately confirm my belief in an awesome and creating Deity. I do not believe that it is useful or productive for anyone to use such images or new scientific discoveries in an attempt to convince others of the existence (or non-existence) of Godโ€”such โ€œproofsโ€ never work. And my impression was that neither the commenter nor I were seeking to do that. We were simply expressing our convictions.

  • Me again: Your โ€œlong-held convictions,โ€ as well as anyone elseโ€™s, are established by far more than โ€œempirical evidence and wide reading.โ€ I have no desire for a debateโ€“the essay is an expression of my own perspective. Not asking you to share it.

Why was I not (am I not) interested in a debate or argument, especially given that such arguments are so endemic to social media? Because a discussion about where oneโ€™s โ€œlong-standing convictionsโ€ come from requires more than sound bites. I have no idea how the commenterโ€™s long-standing conviction that โ€œthe universe is a cold, mindless, soulless void without purpose or meaningโ€ developedโ€”Iโ€™m sure it has been informed and shaped by a lifetime of experiences. Iโ€™m still working on how to explainโ€”to myself primarily, but also to othersโ€”why I believe in an awesome and creating God in the face of what on the surface seems to be so much contrary evidence. Iโ€™ve essentially been working on that for the ten years of this blogโ€™s existence and longer. The best I can say is what Rachel Held Evans used to say: This is the story that Iโ€™m willing to be wrong about. I would love to have a lengthy conversation about our long-standing convictions with the commenter sometime. But not on social media.

I was pleased and satisfied with our final exchange.

  • Him: Fair enough, all your points are valid. There can be no debate between two persons who basically inhabit utterly different realities. That said, you are 100% entitled to express your own perspectives and beliefs and not only do I respect them, but Iโ€™ll always strive to comprehend and understand them.
  • Me:ย Thanks for your commentsโ€“I appreciate them a great deal.

Sometimes the best thing that can happen at the end of a conversation between two people with incompatible long-standing convictions is respectfully wishing each other a good day and walking away. What made this brief exchange both enjoyable, illuminating, and peaceful is that neither of us was threatened by the other. I do not have an agenda for his improvement, and I did not perceive that he had such an agenda for me. Imagine that.
