Neither ;) ... it's that when a novel observation is made, and this observation is encapsulated in a newly-created PredicateNode, then the PredicateNode will have a much higher truth-value than it would have if the observation had not been made. For instance, let's suppose you see a fish riding a bicycle Then there will be a PredicateNode with an internal predicate roughly like ( InheritanceLink (X, fish)) AND ( EvaluationLink( rides , (X, bicycle))) [There are no variables in Novamente internally; but the variable-bearing form is easier for humans to read and can easily be converted to & from the internal combinator-based version] The TruthValue of this PredicateNode is assigned based on the observed frequency of situations in which it's satisfied. This is low, but greater than zero since at least one bicycle-riding fish has been observed. On the other hand, before the observation leading to the creation of the PredicateNode occurred, the inferred TruthValue of this PredicateNode would have been a lot lower (because inference would have led to the conclusion that fish don't ride bicycles). Thus, this PredicateNode experienced an effective *drastic increase in TruthValue*.
