A four-item, seven-point Likert-type scale measuring the degree to which a person believes a social standard makes sense, has a good reason behind it, is beneficial, and is legitimate for a given group. The norm being evaluated is not stated in the items themselves; it must be supplied contextually prior to administration. A blank in item 3 requires the name of the relevant social group to be inserted. Warren and Campbell (2014) created the scale for use in Study 2 (n = 196) and originally called the construct 'legitimacy.' In that study, participants evaluated a norm associated with a fictional city-state called Ballai; the phrase 'Ballai society' was inserted in the blank. Internal consistency was excellent: alpha = .94 (Warren, 2015). The scale was developed quickly for the purposes of a single study and was not subjected to formal validation.
