The justification of deliberate expansion is the topic of this chapter, and it is argued that any possible expansion should be assessed with respect to two desiderata: the enquirer should seek to avoid error by adding new information that is false; and the enquirer should seek to acquire new, valuable information. The ways in which the legitimacy of an inductive expansion is heavily dependant on contextual parameters are set out, and five such parameters are identified. The notions of “degrees of surprise” and “degrees of belief” (plausibility) are defined and discussed.

Keywords: avoidance of error; context dependence; degrees of belief; degrees of surprise; deliberate expansion; plausibility; valuable information
