In practice, decision making rarely depends on the full information that was originally observed¹. Instead, decisions are often based only on the information that was eventually reported. This distinction is fundamental.

An observer may possess richer latent information than the information communicated through the reporting protocol. Consequently, two situations that appear equivalent at the reporting level may correspond to very different informational structures.

Conditional probability is usually introduced theoretically through abstract events and sigma-algebras. However, in practical applications, conditioning frequently depends on:
