Two concerns over the study of the history of masculinity are that it would stabilize the historical process (rather than change it) and that a cultural overemphasis on the approach to masculinity lacks the reality of actual experience. According to John Tosh, masculinity has become a conceptual framework used by historians to enhance their cultural explorations instead of a specialty in its own right. This draws attention from reality to representation and meaning, not only in the realm of masculinity; culture was becoming "the bottom line, the real historical reality". Tosh critiques Martin Francis' work in this light because popular culture, rather than the experience of family life, is the basis for Francis' argument. Francis uses contemporary literature and film to demonstrate that masculinity was restless, shying away from domesticity and commitment, during the late 1940s and 1950s. Francis wrote that this flight from commitment was "most likely to take place at the level of fantasy (individual and collective)". In focusing on culture, it is difficult to gauge the degree to which films such as "Scott of the Antarctic" represented the era's masculine fantasies. Michael Roper's call to focus on the subjectivity of masculinity addresses this cultural bias, because broad understanding is set aside for an examination "of what the relationship of the codes of masculinity is to actual men, to existential matters, to persons and to their psychic make-up" (Tosh's human experience).
