The PHIA Probability Yardstick Most intelligence judgements have some degree of uncertainty associated with them. The intelligence assessment community use terms such as ‘unlikely’ or ‘probable’ to convey this. These terms are used instead of numerical probabilities e.g. 55% to avoid interpretation of judgements as being overly precise, as most intelligence judgements are not based on quantitative data. A Yardstick establishes what these terms approximately correspond to in numerical probability. This ensures that readers understand a judgement as the analyst intends. The rigourous use of a Yardstick also ensures that analysts themselves make clear judgements and avoid the inappropriate use of terms that imply a judgement without being clear what it is (e.g. ‘if x were to occur, then y might happen’). The Professional Head of Intelligence Assessment Probability Yardstick splits the probability scale into seven ranges. Terms are assigned to each probability range. source مرتبط با: https://t.center/nouritazeh/5038
