This property is characteristic of a Guttman scale, in which each item implies agreement with all previous items. The scale is constructed so that a positive response to a higher level item implies agreement with all lower level items. Therefore, researchers can identify the strongest specific item each participant is willing to endorse by locating the first item that the participant does not endorse.
