About this chapter
Information requirements compete for attention and resources, so a useful question is how much an answer is expected to change what is known. Timms, Mandel, and Nelson compare the Indicators Validator structured analytic technique with an information-theoretic approach based on information gain. Through a hypothetical example, they examine limitations of the former and explain how a quantitative account of uncertainty reduction can support the assessment of information usefulness. The chapter’s contribution is a comparison of methods for prioritizing questions. Readers should keep the authors’ proposed measure and its assumptions visible rather than equating the amount of information collected with its value.
