FolkBelief.org is built around documented folklore. Sources matter because a superstition repeated on modern websites is not necessarily evidence of where the belief came from, how old it is, or who actually held it.
Our research approach focuses on traceable evidence, careful geographic attribution, and a clear distinction between documented records, later interpretations, and unsupported repetition.
Types of Sources
Research may draw from folklore collections, academic journals, historical books, ethnographic works, archives, newspapers, libraries, museums, university collections, cultural institutions, and digitized primary sources.
Structured datasets and research databases may also be used when their methodology, scope, provenance, and reuse conditions are sufficiently clear.
The value of a source depends on the claim being supported. A nineteenth-century folklore collection can be strong evidence that a belief was recorded at that time, but it may not prove when the belief originated.
Primary and Secondary Evidence
When possible, original folklore records and early publications are useful for establishing wording, place, date, and context.
Later scholarship can help interpret those records, identify related traditions, compare regional variants, or show how a belief developed over time.
A secondary source is not automatically weaker for every purpose. Its usefulness depends on what it documents, the evidence it cites, and whether its conclusions can be traced back to identifiable material.
External Dataset and Attribution
FolkBelief.org uses selected structured data from the SuperstitionsMap Global Folklore Documentation Dataset, published by SuperstitionsMap, as one of the reference resources supporting parts of our geographic and documentation framework.
The SuperstitionsMap dataset brings together country-level information about documented folklore and belief-related corpora from academic, archival, museum, government, library, institutional, and other traceable sources. Its figures describe documented source corpora rather than the total number of superstitions believed or practiced in a country.
Where SuperstitionsMap data is used on FolkBelief.org, it may be selected, filtered, reorganized, normalized, classified, or combined with additional research to fit the FolkBelief knowledge structure. These adaptations are made by FolkBelief.org and should not be interpreted as modifications made or endorsed by SuperstitionsMap.

How Dataset Figures Are Interpreted
Country-level corpus counts are treated as documentation indicators, not as measurements of how superstitious a population is.
A larger documented corpus may reflect extensive collecting, digitization, archival preservation, or a particularly detailed reference work. A smaller corpus may simply reflect a narrower surviving or accessible source base.
Different sources may also count different kinds of material, including folk beliefs, omens, taboos, legends, folktales, proverbs, recordings, archival units, or other documented traditional-culture records. FolkBelief.org does not automatically convert these different units into claims about equal numbers of individual superstitions.
Repeated Claims
A statement appearing on many websites is not automatically well documented. Repetition can sometimes trace back to a single unsourced claim or to several pages repeating one another.
For this reason, source quality is considered separately from the number of places where a statement has been repeated.
When a widely repeated claim cannot be connected to a sufficiently identifiable historical, scholarly, archival, institutional, or otherwise credible source, its popularity alone is not treated as proof of origin or authenticity.
Dates and Earliest Records
The publication date of a source usually establishes that a belief was recorded by that point. It does not necessarily establish the year or century in which the tradition first developed.
Similarly, the earliest source currently identified by FolkBelief.org should not automatically be interpreted as the origin of a tradition. An older oral or written form may exist without having survived, been digitized, or yet been located.
Geographic Evidence
Location information is preserved as specifically as practical.
A belief collected in one American state, English county, Japanese province, European locality, occupational community, ethnic community, or other documented setting should not automatically be expanded into a claim about an entire nation or population.
Broader geographic labels may be used when several records support a wider distribution, but they are intended to describe documented presence rather than universal belief.
Different Versions of the Same Belief
Folklore frequently exists in more than one form. The same sign, object, action, dream, animal, or event may have different meanings in different sources or locations.
These differences are not automatically treated as errors. When multiple versions are independently documented, FolkBelief.org may preserve them as regional, historical, or contextual variants rather than selecting one version as universally correct.
Source Terminology
Where practical, the original type of material described by a source is preserved. A collection described as legends should not be silently relabeled as a collection of superstitions, and a proverb corpus should not automatically be presented as an equal number of folk beliefs.
This distinction is particularly important when comparing historical collections and structured datasets created under different cataloguing systems.
Uncertainty and Limitations
Folklore research does not always produce a single answer. Sources may disagree, local variants may differ, terminology may change over time, and the historical trail may stop before an origin can be established.
Some traditions are extensively documented while others survive only in a small number of records. Differences in documentation should not automatically be interpreted as differences in cultural importance or prevalence.
When the evidence is uncertain, FolkBelief.org aims to preserve that uncertainty rather than replace it with a more dramatic but unsupported explanation.
Corrections and Source Updates
Source information may be revised when stronger documentation becomes available, when a geographic attribution needs to be narrowed, when a dataset is updated, or when an earlier interpretation does not accurately reflect the underlying evidence.
When external structured data has been adapted for FolkBelief.org, our presentation may differ from the source dataset because of filtering, classification, normalization, additional research, or later corrections.
