The Problem of Evil causes me more trouble in my faith than any other atheistic argument. It’s the best case against God. When I see children with cancer, or hear of vulnerable people being abused, I wonder how God could allow it to happen. The argument comes in several varieties, but it runs something like this: the world contains a lot of evil–let’s say the quantity is X, and X is too much. If the Christian God exists, the world would contain less than X. So, the Christian God must not exist.
Now, the reason we think that X is too much evil is because of its relationship to the amount of good in the world. If there was infinitely more good than evil, then I don’t think the problem would get off the ground. But it seems to many people that the good-to-evil ratio is less than optimal. Maybe there’s more evil than good, or maybe there’s just not enough good to “make up” for the evil in the world. Maybe the ratio would need to be 100:1 (good:evil), or 1,000:1. But whatever the ratio is, it seems wrong for a world superintended by the Christian God.
Doubting My Doubts
But a year or so ago, I read about something that made me question my reasoning about evil: negativity bias. Could it be that the power of the Problem of Evil argument rests on a flaw in our cognition? I first encountered the concept in Daniel Kahneman’s book, Thinking, Fast and Slow. They call it “negativity dominance.” They talk about how the brain reacts more strongly to negative experiences than positive ones. For instance, look at these two images:
According to Kahneman’s research, the image on the left will cause your heartbeat to speed up, but the image on the right will not. Researchers have also found that angry faces “pop out” of a series of faces, but happy faces don’t.(1) Negative images and experiences affect us more deeply and broadly than positive ones, and stick in the memory easier.
In a paper entitled, “Bad Is Stronger than Good,” researchers wrote:
Bad emotions, bad parents, and bad feedback have more impact than good ones, and bad information is processed more thoroughly than good. . . Bad impressions and bad stereotypes are quicker to form and more resistant to disconfirmation than good ones.(2)
Another study claims that, “There is ample empirical evidence for an asymmetry in the way that adults use positive versus negative information to make sense of their world; specifically, across an array of psychological situations and tasks, adults display a negativity bias, or the propensity to attend to, learn from, and use negative information far more than positive information.”(3) You only need to google “negativity bias” to see the mass of evidence. The bottom line is that our perception of the world is slanted. We tend to notice more bad than good, remember more bad than good, and feel the impact of bad more than good.
A Defeater for the Problem
So why is this a problem (or a ‘defeater‘) for the atheistic argument from evil? It undermines the argument, or at least the force of it, because our judgment about the good-to-evil ratio in the world is purely subjective. And if it is subjective, then it is undoubtedly inaccurate, and not just by a little. The bias is quite potent. How much good did we miss or forget or discount? How have we exaggerated evil in our minds? It’s not unlike an optical illusion.
The truth is, we don’t know what the actual ratio is. Gathering such data accurately seems nearly impossible. But once we know we have a bias toward noticing and feeling evil, we should recalculate our judgment about the ratio. We should tell ourselves, “It may seem like there is far more evil than good in the world, but the ratio is probably closer to 1:1 than I thought.” And this should, rationally, lead us to doubt the force of the Problem of Evil.

One thought on “Negativity Bias and the Problem of Evil”
As an atheist, I dislike the Problem of Evil as an argument for atheism, since I believe it could lead to a kind of faith-based atheism that I would find abhorrent. I don’t believe in God, but it is an article of faith for me that God is not an… Well, let’s keep this family friendly and say “jerk.” (And it really annoys me when theists attempt to disprove this article of my faith.)
Negativity bias in humans is very real, in part because it plays a role in skill-learning. Successful use of a routine reinforces the ‘program’ additively, but a failure in execution of a skill demotes the ‘program’ exponentially. My personal view of humanity is it isn’t that we’re evenly bad or good, but we’re all 90% good and 10% bad hair day. And even that’s probably an overly negative take on reality.
But, still, even if the world is 99.999% good, or how ever many 9s you’d like to tack on, there is still that remaining iota of badness. And that iota is still enough to generate a Problem of Evil: why would an all-knowing, all-powerful, all-good God tolerate even that last iota of badness?
I have a solution to this… quad-lemma? that works for me, and allows me to postulate a cosmos where God exists and is not a jerk. But it is reasonably heretical, and I would not expect most Christians to accept it. So I’d like to hear what solutions you guys have worked out for yourselves.
