Where this record's text came from. faceted 2026-08 by reading the locally held text (pdftext); every evidence string verified as an exact substring of that text before merging. The raw treatment difference in contributions was NOT significant (Kolmogorov-Smirnov p = 0.552; Wilcoxon p = 0.249); the claim holds only with a gender control, which the abstract states explicitly and I have quoted verbatim. The paper frames itself as the first to test priming where there is a clear financial incentive to free ride ('This is our novel contribution to the literature as no previous studies have investigated priming in an economic game where there is a clear financial incentive to free ride.'), so no replication of it is reported. Note the PDF extraction renders some apostrophes as U+201F ('women‟s'); quotes preserve that character exactly. A secondary mechanism claim (beliefs mediate the gender effect) is present but the headline contribution is the existence of the effect, hence claim type existence. 2026-08-17 and 2026-08-25 schema-0.3 passes: every quote verified as an exact substring of the staged text and anchored at merge time; concept terms verified present; every edge endpoint an existing node.
How to read this page. The article itself is not reproduced here — this paper is not cleared for redistribution, so what follows is the tag layer alone. The evidence sentences are withheld with the article. The table at the foot lists every tag the record carries; each row names the facet it belongs to, and the whose words column says whether the tag records the paper's own wording or the tagger's sentence about the paper. Every tag links to each other paper in the corpus carrying it. The machine-readable edition of the same thing is the TEI file beside this one, where the tags live in standOff, and the article is at its publisher via the link below. When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.

Tags on this paper

Every tag the record carries, each linking to every other paper in the corpus that carries it. A tag appears here whether or not its words occur in the article — the spans below are only the ones a sentence in this paper licenses. Of the 8 concept tags on this paper, all 8 are grounded in a quoted sentence. All carry the tagger's gloss of what the term means in this paper, which is not something the article can license.
priming framing contribution levels beliefs gender emotional responses revealed preferences contribution decisions Priming works in two steps: the cooperation words first raise women's beliefs about how much the other group members will give, and those raised beliefs then drive their own contribution decisions The primes serve as anchors or focal points on which subjects can coordinate, which lowers the strategic risk of contributing and so releases more generous behaviour, particularly among women The word-search puzzle acts as a subconscious reminder of cooperation, raising the accessibility of the concept at the moment of choice NP-treatment and P-treatment priming manipulation Level of contributions Beliefs about contributions field of study and nationality ordinary least squares regression OLS estimates ordered probit regression ordered probit model Wilcoxon rank-sum test non-parametric ranksum Wilcoxon test Kolmogorov-Smirnov test Spearman rank correlation Spearman correlation robust standard errors Robust standard errors are presented in parentheses locally weighted regression (lowess) the locally weighted regression behavioural-experiment

The paper

The full text is not reproduced here. This article is not cleared for redistribution, so the page carries the tag layer only. Its evidence sentences are withheld; the grounding status remains with each tag, and the article itself is at https://doi.org/10.2139/ssrn.1631098. The reading view exists for the papers whose licence permits it.

Relations on this page carry a quotation for the claim. Where a relation was separately evidenced — and so tested against the vocabulary for its type — the row says so; none of 5 relations here carry that mark. The rest are the tagger’s reading of the sentence quoted beside them.

unhoused_relationspriming works through a shift in females’ beliefs (this paper, IZA DP 4963, May 2010) → priming does not affect beliefs and works by changing preferences (the same authors' published version, Theory and Decision 2015, in this corpus as drouvelis2015-cooperation-priming)
Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above.
SAME AUTHORS, SAME EXPERIMENT, OPPOSITE MECHANISM - AND THE SCHEMA HAS NO TYPE FOR IT. The 2015 paper reports two waves, the first run in 2009 with 51 and 54 subjects, which is this paper's N. So this working paper is wave one and the publication is wave one plus wave two. In wave one the raw contribution difference is NOT significant (Wilcoxon two-sided p = 0.249) and the effect appears only with a gender control at the 10% level, carried by a four-cell split of 105 subjects (19, 25, 32, 29); the mechanism is stated as two steps through female beliefs. In the pooled publication the raw difference IS significant (p = 0.044 one-sided), there is `insufficient evidence to suggest that the effect of priming varies significantly across ... gender`, and `priming does not affect subjects' beliefs`, which is precisely what licenses its claim that priming works through PREFERENCES. So the whole two-step belief mechanism, and the gender effect that motivated it, are absent from the published version of the same experiment. Neither paper is being called wrong here: more data arrived and a subgroup result did not survive it. What the corpus can record is that both statements exist, that they are by the same authors about the same data plus more, and where each one is. `superseded-by` / `revised-in` is the type this needs and the vocabulary does not have it - on the schema's missing relation types.
