However, the relational algorithm also embodies an important selection criterion: Is this event connected to that event? Theorists often assume that events are unrelated and reactions of interest often result when unexpected connections are discovered (Davis, 1971). To discover an unexpected connection is to discover a new set of implications. Thus, while the relational
algorithm is a valuable device to create independence among thought trials-it puts domain words into relations that the theorist forgot about-it also activates the selection criterion of connections. The assumption that events are un related is disconfirmed when people discover they are connected and the reaction that's inter esting serves as a clue to retain the conjecture.
