Discovery Lab Answers

I don’t have a “Günzel database” in the retrieved sources, and nothing in the ESP-Nexus project knowledge or the numbered library references corresponds to a database by that name. So I can’t tell you which of its studies carry retrodictively-analyzable qualitative data — the premise names a specific holding the library doesn’t contain, and I won’t invent an answer for it.

A couple of things worth clarifying so you can redirect:

What I can’t confirm

• There is no “Günzel database” among the retrieved sources or in ESP-Nexus’s described corpus. If this refers to a specific published dataset or a named researcher’s collection, I have nothing on it here, and I won’t guess at its contents.

What the retrieved sources DO contain (qualitative material)

If your underlying interest is “which studies in the library hold qualitative narrative data that could support a retrodictive or exploratory re-analysis,” several of the numbered sources are qualitative or narrative in nature — though note this is a small retrieved slice, not a systematic map of the library:

• Ait Melloul, Kinnunen and Cardeña (2024) analyzed eight distressing near-death experience narratives from the IANDS database using Interpretative Phenomenological Analysis — explicitly qualitative narrative data ^[2].
• Tressoldi and Long (2023) coded descriptions of God’s and Jesus’ characteristics from 303 near-death or near-death-like experiencers — a coded qualitative corpus ^[1].
• The linguistic-patterns NDE study (2017) worked from a database of NDE accounts analyzing their structure and semantics ^[4].
• Matthews (2025) examined anomalous-experience narratives across citizen-science datasets ^[6].

Whether any of these is amenable to retrodictive analysis specifically (i.e., testing predictions against already-recorded outcomes) depends on how you define the term and on data access — none of the retrieved abstracts frames itself that way.

If you can tell me what the “Günzel database” actually is, or point to where you encountered it, I can check whether the library holds anything matching it. You may also want to browse the Studies section directly to see the single-study audit pages by topic.
