Infrastructure bias

In economics and social policy, infrastructure bias is the influence of the location and availability of pre-existing infrastructure, such as roads and telecommunications facilities, on social and economic development.

In science, infrastructure bias is the influence of existing social or scientific infrastructure on scientific observations.

In astronomy and particle physics, where the availability of particular kinds of telescopes or particle accelerators acts as a constraint on the types of experiments that can be done, the data that can be retrieved is biased towards that which can be obtained by the equipment.

Procedural bias, related to infrastructure bias, is shown by a case of irregular genetic sampling of Bolivian wild potatoes.<ref name=DivaGIS>"Assessing the geographic representativeness of genebank collections: The case of Bolivian wild potatoes" (PDF).
