Great response — and I appreciate the nuance you're bringing.
You're absolutely right that we can shape the environment in which belief is more or less likely to arise. We can choose what we read, who we spend time with, what ideas we expose ourselves to. Those indirect choices matter. They help explain how some beliefs take root and others don’t. So yes — we can influence belief. But that’s not the same as choosing it.
Because here’s the deeper issue: influence isn’t control, and effort doesn’t guarantee conviction.
There are countless examples of people who have done all the “right” things — opened themselves up to belief, read the scriptures, prayed, pleaded, surrounded themselves with believers, sincerely tried to find faith — and still found that belief did not come. They were not being stubborn or rebellious. They were simply not convinced. That was me for many years. And just as you can’t force yourself to find a joke funny, you can’t force yourself to find a claim credible. That sense of conviction has to arise — and it either does or it doesn’t.
Even in the echo chamber scenario you described — someone immersing themselves in a particular worldview — the feeling of belief may emerge, but it still isn’t summoned by will. It's the product of exposure and reinforcement. And crucially, even that effect doesn’t always work. Plenty of people remain resistant to belief despite intense pressure to conform — and others fall into belief despite exposure to very little.
That unpredictability is part of the point: belief is not a choice, it’s a psychological outcome.
So yes, we’re responsible for the effort we make — the honesty, openness, and intellectual integrity we bring to the table. But if belief is not something we can choose directly, then moral or eternal judgment should never hinge on whether that belief arose in us. Surely the better standard is sincerity, not assent?
