Bayesian thinking · IN SHORT

New evidence.Updated confidence.

State what you believed before a new signal arrived, then inspect its quality. This English skill updates confidence without inventing probabilities and suggests the next informative test.

Your brief

Three prospects asked for an export feature, but all came through one partner. Does this justify building it?

Possible draft

Fictional example: feature demand

Confidence in demand rises slightly. The requests may share one cause, so the next step is a prototype test with prospects outside that partner channel.
