How do locals know which vendor is actually growing the produce they sell?
Products carry traces of their journey.
Markets contain many products but also many stories about where those products came from.
The hidden mechanism is source familiarity. Regular shoppers gradually learn which vendors consistently sell products that match local growing seasons, regional harvest timing, and known farming patterns.
Imagine a vendor offering the same seasonal products year after year with detailed knowledge about harvest conditions. Over time, customers accumulate evidence about sourcing credibility.
A second-order effect develops because trust compounds. Vendors known for transparent sourcing attract repeat customers, making reputation itself a valuable market asset.
People often think origin is something written on a sign. In many markets, origin is something learned through relationships.
