Introduction
Gender ideology has emerged as a central topic in contemporary academic and public discourse, reflecting broader debates about identity, equality, and social norms. Rooted in feminist theory and gender studies, the term initially gained traction through the work of scholars such as Simone de Beauvoir (1949), who famously asserted in The Second Sex that “one is not born, but rather becomes, a woman” (p. 267), emphasizing the social construction of gender and challenging the notion that biology alone determines one’s destiny. This insight laid the groundwork for subsequent scholarship that sought to disentangle gender from biological sex, highlighting the role of cultural, historical, and social factors in shaping gender identities and roles (Oakley, 1972). The 1990s marked a significant turning point with the publication of Judith Butler’s Gender Trouble (1990), which introduced the concept of gender as a performative act: a series of repeated behaviours and expressions that create the illusion of a stable gender identity (p. 25). Butler’s work challenged the binary understanding of gender as strictly tied to biological sex, opening up new avenues for exploring non-binary and fluid gender identities. Over the past few decades, these theoretical developments have profoundly influenced public policies and social practices aimed at promoting gender equality and LGBTQIA+ rights.
However, the term gender ideology has undergone a profound semantic transformation that cannot be understood without tracing its specific political genealogy. Far from originating within academic gender studies, the expression was deliberately constructed as a rhetorical and political weapon. Its earliest traceable roots lie in the activism of Dale O’Leary; in her book The Gender Agenda: Redefining Equality (1997) drew upon the political controversies that erupted at the 1995 Fourth World Conference on Women in Beijing, where the use of the term gender, in place of sex, by feminist and LGBTQ+ advocacy groups was fiercely contested by pro-family delegations. During the preparatory sessions in New York, conservative delegates, misreading or deliberately distorting academic articles on intersexuality began to frame gender as a coded synonym for homosexuality and a vehicle for a broader progressive agenda. O’Leary mobilized the expression “gender feminism”, a term coined by Christina Hoff Sommers (REF), to designate this alleged coalition of population control advocates, sexual libertarians, LGBTQIA+ activists, postmodernists, and neo-Marxists supposedly backed by liberal governments and multinational corporations.
This initial framing was subsequently institutionalized through the Catholic Church. Following the Beijing controversy, the Pontifical Council for the Family launched the Lexicon, a glossary of ambiguous and disputed terms on the family, which included essays by theologian Jutta Burggraf and Peruvian bishop Óscar Alzamora Revoredo, who authored the entry Gender Ideology: Dangers and Scope. The Pontifical Council officially adopted the expression to describe an ideology allegedly aimed at devaluing the complementarity of the sexes and justifying same-sex unions, a framing later echoed by both Pope Benedict XVI (Ratzinger) and Pope Francis (Bergoglio) in their public statements. As Judith Butler argues in Who’s Afraid of Gender? (2024), this ecclesiastical construction gave the term its peculiar power: by functioning as a political phantasm, an empty yet emotionally charged signifier, gender ideology could condense a wide array of social anxieties about family, national identity, and moral order, rendering them legible as a single, conspiratorial threat. The expression subsequently migrated from Catholic discourse into the secular far-right, being taken up by political leaders such as Viktor Orbán and Georgia Meloni, and more recently by Donald Trump, each deploying the phantasm of gender ideology to galvanize reactionary constituencies against feminist and LGBTQIA+ rights (Butler, 2024).
The controversy surrounding gender ideology has had tangible effects on public policy and education. In several countries, debates over the inclusion of gender-related content in school curricula have sparked widespread protests and legislative battles (Kuhar & Paternotte, 2017). For example, in Italy, opposition to gender ideology gained momentum in 2013, with conservative and Catholic groups organizing protests against educational initiatives aimed at combating gender stereotypes and promoting inclusivity in schools (Garbagnoli, 2016; Perocco, 2018). In 2021, the Italian government faced significant backlash from right-wing parties and religious organizations over the proposed Ddl Zan, a bill aimed at combating homophobia and transphobia, which was ultimately blocked in the Senate (Bello, 2021). Similarly, in France, the movement La Manif Pour Tous emerged in 2012 to oppose the legalization of same-sex marriage and later mobilized against the introduction of gender equality programs in schools, framing them as part of a broader “gender theory” agenda (Fassin, 2016). More recently, in 2021, French conservative groups protested against the inclusion of gender-sensitive language in educational materials, arguing that it undermines traditional linguistic norms and family values (Avanza, 2021). These movements have successfully influenced public opinion and policy, leading to the withdrawal or modification of gender-related educational materials in some regions (Corredor, 2019).
Beyond France and Italy, similar patterns have emerged in other European countries. In Poland, for instance, the Law and Justice Party (PiS) has actively promoted an anti-gender discourse since 2015, labeling gender studies as an “ideology” and cutting funding for gender-related academic programs (Graff & Korolczuk, 2022). These developments underscore the highly politicized nature of the term “gender ideology” and its capacity to galvanize both support and opposition across diverse cultural and political contexts.
Belief Systems and Attitudes Toward Gender Ideology
Belief systems, understood as organized frameworks of knowledge, values, and assumptions that shape how individuals interpret the world, are central to understanding societal responses to contested issues like gender ideology. Rooted in social psychology, belief systems function as cognitive filters, guiding perceptions, attitudes, and behaviours. They are often reinforced by cultural, religious, and institutional narratives, creating a common sense that endorses certain worldviews while marginalizing others (Fishbein & Ajzen, 2010). Within this framework, attitudes toward social groups, including sexual minorities, are not independent judgments but rather downstream expressions of broader ideological commitments embedded in one’s belief system (Herek, 1987; Jost et al., 2004).
The debate over gender ideology illustrates how belief systems do not merely reflect pre-existing values, but actively construct the meaning attributed to social phenomena. For individuals embedded in worldviews that privilege tradition, hierarchy, and biological essentialism, gender ideology is not simply a theoretical framework to be evaluated, but an intrusion into a moral order perceived as natural and divinely sanctioned (Garbagnoli, 2016; Corredor, 2019). Conversely, those operating within egalitarian belief systems interpret the same discourse as a necessary corrective to structural inequalities, drawing on a tradition that situates gender as a historically produced and transformable category (Butler, 1990; Fishbein & Ajzen, 2010). It is within the former type of belief system, organized around tradition, authority, and moral purity, that opposition to gender ideology finds its most coherent psychological grounding. These groups frequently portray gender ideology as a destabilizing force, invoking concerns about purity, natural order, and moral contamination, themes that resonate with the Purity/Sanctity foundation identified within Moral Foundations Theory (Haidt & Graham, 2007; Graham et al., 2013). According to this framework, individuals who place greater weight on foundations of Authority and Purity tend to evaluate non-normative gender identities and sexual orientations as threats to the natural and moral order, thus producing more negative evaluative responses toward LGBTQIA+ individuals (Haidt, 2012).
What is commonly labelled as homophobia or sexual prejudice (Herek, 2004) can thus be understood not as a discrete psychological trait, but as a predictable output of specific belief systems that frame heterosexuality and binary gender as natural, divinely sanctioned, and socially necessary. From this perspective, negative attitudes toward gay men and lesbians emerge as coherent expressions of a broader ideological worldview rather than as isolated or irrational reactions (Herek, 1987; Jost et al., 2004). Indeed, research grounded in System Justification Theory has shown that homonegativity functions as a legitimizing myth of gender hierarchy, reinforcing the perceived fairness and naturalness of heteronormative arrangements (Ferrari et al., 2021). Similarly, right-wing authoritarianism, which reflects deference to authority and adherence to social conventions, consistently predicts sexual prejudice precisely because it reflects a belief system organized around the preservation of established hierarchies and moral norms (Altemeyer, 1996; Whitley, 1999; Hoffarth & Liaquat, 2021). In this sense, the opposition to gender ideology and the expression of homonegativity represent two intertwined manifestations of the same underlying system of beliefs about social order, nature, and moral legitimacy.
Attitudes toward gender ideology are deeply embedded within competing belief systems, reflecting broader ideological battles over social norms and values. Defined as evaluative judgments ranging from favorable to unfavorable (Eagly & Chaiken, 1993), these attitudes are not merely personal opinions but may be shaped by divergent worldviews. On one side, individuals anchored in belief systems that prioritize tradition and hierarchy often perceive gender ideology as a potential moral threat, sometimes associating it with conspiracy theories (e.g., “global elites imposing a hidden agenda”) and expressing concerns about societal destabilization, particularly through education systems that promote gender diversity (Paternotte & Kuhar, 2018; Buss et al., 2020). This negative framing tends to revolve around three interconnected themes: 1) the notion of a covert agenda to undermine cultural norms, 2) concerns about children’s “indoctrination” via inclusive education, and 3) the perceived erosion of traditional family structures (Garbagnoli, 2016; Graff & Korolczuk, 2022). For example, opponents frequently claim that gender ideology is being advanced by international organizations or political elites, framing initiatives like LGBTQ+ inclusive curricula as potential threats to “natural” gender roles and familial stability (Verloo, 2018). Conversely, individuals with an egalitarian ideological orientation may perceive gender ideology as a pivotal framework for challenging oppressive structures and promoting equality.
Developing a Measure of Gender Ideology
There is a lack of reliable and valid instruments to measure the attitudes associated with the negative perception of gender ideology. Existing scales do not fully capture the unique dimensions of this phenomenon, particularly the core claims that gender ideology seeks to collapse natural differences, posing a threat to children and the traditional family and that it represents an imposition from global elites.
Given this gap, the present study proposes the development and validation of a multidimensional scale specifically designed to measure negative perceptions of gender ideology: the Gender Ideology Belief Scale (GIBS). Unlike previous instruments, the GIBS systematically integrates key elements of anti-gender discourse, ensuring a comprehensive assessment of opposition to gender-related social change.
The GIBS is structured around three core factors that encapsulate the dominant themes in anti-gender discourse, each reflecting broader socio-political concerns and resistance to shifts in gender norms.
The first factor, conspiracy, encompasses the perception that gender ideology is a deliberate strategy orchestrated by powerful elites or international organizations. This perspective frames gender discourse as a form of social engineering designed to erode cultural traditions, national sovereignty, and established moral values. Such narratives position gender-related policies and initiatives as external impositions that threaten the fabric of society, reinforcing a sense of collective victimization and distrust toward global institutions (Garbagnoli & Prearo, 2017).
The second factor, education, captures opposition to the integration of gender-related topics into educational curricula. This resistance is often rooted in the belief that such content could disrupt children’s cognitive and emotional development, undermine parental authority, and challenge religious or cultural values. Opponents argue that discussions on gender diversity and sexual orientation should remain within the purview of the family rather than be institutionalized within formal education (Schettini, 2023).
The third factor, values, reflects a strong commitment to conventional family structures and gender roles, which are perceived as being under attack by gender ideology. This perspective emphasizes the importance of binary gender distinctions, heterosexual marriage, and clearly defined roles for men and women as fundamental to social stability and moral order. The promotion of alternative family models or non-normative gender identities is frequently interpreted as a direct challenge to these traditional foundations, fueling resistance to policies or discourses advocating for greater gender inclusivity and diversity (Spallaccia, 2020).
Together, these three factors illustrate the multifaceted nature of anti-gender discourse, demonstrating how opposition to gender-related social change remains deeply intertwined with broader anxieties about cultural transformation, institutional authority, and the perceived erosion of traditional societal structures.
Item Generation
The items for the Gender Ideology Belief Scale (GIBS) were developed through a multi-phase procedure aimed at maximizing theoretical coherence, content relevance, and ecological validity. In the first phase, we conducted a comprehensive review of the literature on anti-gender discourse, drawing on contributions from social psychology, political psychology, gender studies, and adjacent fields concerned with ideological resistance to social change. This review made it possible to identify the main themes, symbolic oppositions, and recurrent rhetorical patterns underlying negative representations of gender ideology, as well as to situate these representations within broader belief systems related to tradition, hierarchy, and moral threat. Particular attention was devoted to theoretical and empirical work describing how opposition to gender-related social change is often articulated through concerns about the erosion of natural sex differences, the protection of children, and the preservation of the traditional family. In the second phase, we complemented the academic review with an analysis of publicly available materials reflecting anti-gender discourse in naturalistic settings. These materials included political speeches, media reports, manifestos produced by anti-gender movements, and statements disseminated by religious and conservative advocacy groups. The aim of this phase was to identify the arguments, claims, and narrative frames most frequently mobilized in public opposition to gender-related social change, thus ensuring that the scale would not rely exclusively on abstract theorization but would also reflect the language and meanings circulating in real-world debates. This inductive examination proved particularly useful for capturing the concrete discursive expressions through which anti-gender beliefs are communicated, legitimized, and socially reproduced. The analysis of these materials further reinforced the relevance of three recurring domains, namely conspiratorial interpretations of gender ideology, resistance to gender-inclusive education, and the defense of traditional family and moral values. On the basis of the evidence gathered in the first two phases, the third phase focused on generating an initial pool of items intended to represent the content breadth of the construct. Items were written to reflect each of the three theoretically grounded dimensions, while also capturing variability in tone and intensity, ranging from explicit conspiratorial claims to more socially acceptable or culturally normalized expressions of concern about education, morality, and family order. In drafting the items, care was taken to preserve conceptual specificity, avoid excessive redundancy, and ensure that statements remained understandable, concise, and suitable for administration in a self-report format. This stage resulted in a broad preliminary item pool designed to provide adequate coverage of the multidimensional nature of anti-gender beliefs. In the fourth phase, the preliminary item pool was submitted to expert evaluation involving scholars with expertise in psychology, political science, and gender studies. The purpose of this review was to assess the conceptual clarity, representativeness, and theoretical consistency of each item, as well as to identify possible sources of ambiguity, overlap, or unintended bias. Experts were invited to provide qualitative feedback on the wording of the items, their correspondence with the intended dimensions, and their ability to capture ideologically meaningful content without introducing unnecessary complexity. On the basis of this feedback, several items were revised, re-worded, or discarded in order to improve precision and reduce redundancy. This iterative process led to a refined set of 24 items that were judged to be more clearly aligned with the theoretical framework and more suitable for subsequent psychometric testing.
