MFV: add SOURCES.md audit trail (citations, URLs, transforms) for all 8 country rows
Consolidates provenance that was only in terse CSV source-tags + commit bodies: per source, full citation + DOI/OSF URL + which table/figure + the exact data transformation (Care-collapse, Brazil affine bias-cal, Australia raw-recompute).

# Sources & provenance: `mfv_country_factors.csv`
|
||||
|
||||
Audit trail for the human country rows in the MFV value map. One entry per `source`
|
||||
tag in the CSV. Each entry records: full citation, URL/DOI, exactly which table/figure
|
||||
the numbers came from, and any data transformation applied (so a reviewer can reproduce
|
||||
the row from the primary source).
|
||||
|
||||
Author of these notes: Claude (pair-programming with wassname), not wassname.
|
||||
|
||||
## Instrument & how the map uses these numbers
|
||||
|
||||
All rows are the Clifford et al. (2015) Moral Foundations Vignettes (MFV): 2nd-person
|
||||
"You see ..." vignettes rated for moral wrongness on a 1-5 scale, coded to six
|
||||
foundations (care, fairness, liberty, authority, loyalty/ingroup, sanctity/purity).
|
||||
|
||||
The value map (`scripts/plot_steer_showcase.py::read_human_mfv`) reads **only the `mean`
|
||||
column**, then **z-scores each country across its six foundations** (ipsative). Because
|
||||
z-scoring is affine-invariant, any per-country scale/offset (translation bias, digitizing
|
||||
bias, differing scale anchors) cancels: the map shows *relative* foundation emphasis, not
|
||||
a calibrated cross-country ranking. Absolute means/SDs are still stored honestly for any
|
||||
non-map reuse.
|
||||
|
||||
Caveat carried by two of the source papers (Jimenez-Leal, Hopp): the MFV shows
|
||||
measurement non-invariance / differential item functioning across countries, so raw
|
||||
between-country mean comparisons are a rough reference, not a validated ranking.

- Numbers: foundation means + 95% CIs from the paper's Table 1 (N = 586 Dutch crowdworkers,

differs per row).
|

- Transformation: **Care collapsed** from the paper's split physical-care (4.09) +
|

emotional-care (3.53) into a single care = 3.81 (mean of the two). Other foundations

PDF: http://journal.sjdm.org/19/190809a/jdm190809a.pdf
|
||||
- Numbers: the paper tabulates no per-foundation means, so means were **digitized from
|
||||
Figure 3** (Brazil series) with WebPlotDigitizer by wassname. N = 494 (paper).
|
||||
- Transformations (two, both by Claude):
|
||||
1. **Care collapsed** from digitized Care-E + Care-P into one care value.
|
||||
2. **Affine bias-correction** of all digitized means to two paper-stated Purity anchors
|
||||
(Brazil purity 3.45, Clifford US purity 3.85; paper text): `true = 0.9155*digitized
|
||||
+ 0.228`. Reproduces both anchors; Brazil purity lands exactly 3.45. SDs recovered
|
||||
from the digitized 95% CI whiskers (Fig 3 caption): `sd = halfwidth/1.96 * sqrt(494)`;
|
||||
each whisker pair's midpoint matches its mean to <=0.005 (validated). SDs scaled by
|
||||
the affine slope. Provably map-neutral (max |dz| = 0.017, rounding only).

|

- DOI: https://doi.org/10.3758/s13428-020-01489-y . OSF: https://osf.io/cmwpv/
|
||||
(component "Data" = https://osf.io/nv4ty/ , file `dat_rep.sav`).
|
||||
- Sample: 756 Australian undergraduates (complete cases). The paper's other sample is
|
||||
580 US MTurk workers (`dat_amt`), NOT used here -- that would duplicate the US row.
|
||||
- Numbers: computed by Claude from the **raw participant ratings** in `dat_rep.sav`, the
|
||||
full 90-item Clifford MFV (1-5 wrongness), using the author's own item->foundation map
|
||||
from `mfv_abbreviation.Rmd` (Care = MFV 1-27 [physical+emotional+other], Fairness 28-39,
|
||||
Liberty 40-50, Authority 51-64, Loyalty/Ingroup 65-80, Sanctity/Purity 81-90).
|
||||
Per foundation: mean over participants of each participant's item-mean; SD = between-
|
||||
participant SD (ddof=1); SE = SD/sqrt(N); CI = mean +/- 1.96*SE. Complete-case exclusion
|
||||
(all 90 items present) reproduces the paper's N = 756 exactly.
|
||||
- Transformation: **NOT the genetic-algorithm-abbreviated subset.** The paper's headline
|
||||
contribution is a brief MFV chosen by GAabbreviate; we deliberately used the *full*
|
||||
90-item ratings so Australia is comparable to the other (full-instrument) country rows.
|
||||
Care spans all 27 care items (no collapse needed; it's the natural mean).
|
||||
- Reproduce: OSF files fetched via `https://osf.io/download/4psfc/` (dat_rep.sav);
|
||||
read with `pyreadstat.read_sav`. (The OSF "Download as zip" gave an empty archive --
|
||||
fetch files individually.)
