Breaking down the question
This is an evaluative question. The phrase universally applicable is a claim to be tested, and the command word Elucidate asks you to explain the theory clearly and then judge how far it holds across contexts. Do not simply describe reference group theory; weigh its claim to general validity.
The balanced position is that reference group theory captures a genuinely widespread social process — people evaluating themselves against groups other than their own — yet its explanatory reach has limits, both empirical and cultural. Success depends on presenting the theory accurately and then marshalling considered points for and against its universality.

How to approach it
Begin by outlining the theory. A reference group is any group an individual uses as a standard for self-evaluation and attitude formation, whether or not they belong to it. Trace it from Herbert Hyman's coinage and Samuel Stouffer's studies of the American soldier to Robert Merton's systematisation, and introduce the linked concepts of relative deprivation, anticipatory socialisation, and the distinction between membership and non-membership, and between normative and comparative reference groups.
Then evaluate universality. In its favour: the process of comparative self-evaluation appears across societies and helps explain deprivation, mobility aspirations and social change. Against: reference group choice is patterned by culture and structure, so a model derived from a mobile, individualistic society may fit rigidly hierarchical or collectivist settings less well; the theory can also seem indeterminate, since it rarely predicts which group a person will select. Our Merton notes develop these concepts further.
Conclude with a qualified verdict.
Model answer
Reference group theory holds that individuals evaluate themselves, form attitudes and shape aspirations by reference to groups they take as standards — groups to which they may or may not belong. The idea was introduced by Herbert Hyman, given empirical force by Samuel Stouffer's wartime studies, and systematised by Robert Merton. Merton linked it to relative deprivation, the sense of disadvantage that arises not from absolute conditions but from comparison with a reference group; to anticipatory socialisation, whereby a person adopts in advance the values of a group they aspire to join; and to key distinctions between membership and non-membership groups, and between the normative function of a reference group, which sets norms, and its comparative function, which provides a yardstick for judgement.
The theory has a strong claim to wide applicability. The underlying process — judging one's situation relatively, against a chosen standard — appears to be a general feature of social life, and it illuminates phenomena as varied as army morale, consumer aspiration, mobility and the discontent that fuels social movements. Because it works at the level of the individual's orientation to groups, it can be applied in many institutional settings.
Yet its claim to be universally applicable must be qualified. First, the choice of reference group is itself shaped by social structure and culture, so a model developed in a mobile, individualistic society may translate imperfectly to rigidly stratified or strongly collectivist contexts, where ascribed status limits the groups one may realistically adopt as standards. Second, the theory is often criticised as indeterminate: it explains behaviour well after the event but rarely specifies in advance which of many possible groups an individual will select, or why. Third, it privileges individual comparison and can underplay the structural constraints within which such comparisons occur.
The reasonable verdict, then, is that reference group theory identifies a near-universal social process but does not amount to a universally applicable model with fixed predictive power. Its value is as a flexible analytical framework, whose specific application must be adjusted to the cultural and structural setting in which comparison takes place.
Examiner's perspective
The examiner is testing judgement. The question plants the strong claim universally applicable precisely so that candidates can interrogate it; an answer that only recounts Merton's concepts, without assessing their general validity, fails to engage the actual question.
High-scoring scripts explain the theory economically — anchoring it in Hyman, Stouffer and Merton and defining relative deprivation and anticipatory socialisation — and then argue both sides, distinguishing the near-universality of the process of comparison from the more limited universality of the model. Noting cultural variation in reference group choice and the charge of indeterminacy shows critical depth, and a clear qualified conclusion signals the balanced reasoning expected at this level.
