Episode notes
Big Surveys Form The Empirical Backbone
- Invest in large, well-designed surveys if you want to understand national-scale religious trends.
- Smaller, qualitative studies need a strong quantitative backbone to contextualize findings.
Machine Learning Reveals Four 'Nones'
- Machine learning clustering revealed four distinct subgroups among American 'Nones' rather than one monolithic group.
- This method surfaced patterns researchers admit they would likely have missed by hand-coding categories.
Let Data Drive Categories
- Use unsupervised methods (like K-means) to let patterns emerge rather than imposing categories.
- Then interpret clusters qualitatively to name and understand each group responsibly.
