Ah, sorry about that. I think this is a really interesting topic that might merit a thread of its own. Journeys like that one (Creationism → Theistic Evolution) are bigger than just “learning” or “changing one’s mind” and are obviously similar to seismic changes like deconversion.
There are many public personal stories of escape from creationism with faith intact. I think there are several at the BioLogos site, and while I’ve never read Lamoureux I think his story is like that. I haven’t read Dennis Venema’s book but I think his journey started with creationism (I know he was an ID enthusiast until he read Behe’s Edge of Evolution, which no geneticist could ever take seriously). Previous generations have escape stories that should also be studied and remembered: Davis Young was a hero of mine many years ago and is an example of escape from creationism (YEC) with faith intact. Ron Numbers’ escape led to agnosticism (as he described decades ago in The Creationists).
I am more personally acquainted with people who I knew who told me their stories. One nearly-universal common thread was an encounter with scientific explanations (and data) that they had never heard or seen before. This encounter was often a college class (weeks or months long) but sometimes just a lecture or article. In every case, the exposure to previously unknown/unexamined science happened in what I’ll call a friendly environment (with one or many other believers) and came from a friendly source (a fellow believer with scientific and religious credibility). There is probably a LOT to unpack regarding that last part — for some of these people, the mere existence of a serious believer who understood evolution was a shocking discovery.
I am emphasizing stories that have a seismic change at the center, because those are the stories I have heard. There are surely stories of the more “small cracks in their worldview” nature. I suspect that even those stories involve a punctuated time of change that gets the person out of the echo chamber for good. But that, like everything else I’ve written here, is based on my experiences in a particular kind of faith community at a particular time in history. As far as I know, there has been no systematic study of these kinds of changes. Such a study would be VERY interesting and may very well turn up influences or vulnerabilities that we don’t think enough about. Or not.
I should add that about half of the stories that people told me (and occasionally still tell me) did not end with faith intact. Those stories are more consistent in their structure and all end with the person realizing they’d been lied to, for decades. They then asked the next important, indeed obvious question: “What else did they lie to me about?” An evangelical who asks that question is in for a rough ride, and no atheist (shrill or otherwise) needs to be around to help.
