Participatory technology assessment (pTA) refers to processes in which citizens and stakeholders are involved in decisions about new technologies (Hennen 2012). According to democratic principles, risk and ethical issues should not be determined solely by expert committees; the public affected should also be heard. In areas of security policy (i.e., technologies that affect the military, intelligence services, or issues of war and peace) these democratic demands face particular hurdles: secrecy, a discourse of urgency (emergency and threat rhetoric), and powerful, often hierarchical actors stand in the way of broad participation. This often means that participation processes in this sector remain rather formal or symbolic acts, without enabling actual co-creation (Heide and Villeneuve 2021).

A prominent example of this tension is the Pentagon’s ‘Project Maven’ (2017–2019), which developed AI technology for object recognition in drone videos. Google was involved in the project as an industry partner at times, but this only became known after the fact. In April 2018, more than 3,100 Google employees protested in an open letter against their company’s role in Maven and demanded that Google should not participate “in the business of war” (Google Employees 2018). The letter, with its core message ‘Google should not be in the business of war,’ made headlines around the world. This sparked a broad debate that revealed contradictions between the company’s publicly proclaimed values and its involvement in military applications. Under pressure from internal protests and negative publicity, Google announced in June 2018 that it would allow the Maven contract with the Department of Defense to expire. This case illustrates, on the one hand, the desire for democratic influence on military technology developments, but on the other hand, the narrow limits of such influence under security policy conditions: Despite Google’s withdrawal, the actual project development continued unabated, now with other companies in the background.

Against this backdrop, the research question arises as to what participatory processes look like and how they work in areas of tight secrecy. Specifically, the article asks: Does pTA in the defense and security sector remain mere symbolic politics? Or are there ways in which participation can lead to real change despite power asymmetries and secrecy? How does this finding contribute to the debate on democratic control of security technologies? The aim of this article is to explore this tension and contribute to technology assessment (TA) and science and technology studies (STS) by examining participatory approaches in the hitherto neglected field of security governance.

Does participatory technology assessment in the defense and security sector remain mere symbolic politics?

Early pTA scholarship argued that involving citizens in technology decisions (via citizens’ juries, consensus conferences, etc.) enhances legitimacy (Hennen et al. 2023; Wesselink et al. 2011). In practice, however, critics observed that such exercises often reproduce existing hierarchies rather than disrupting them (Felt and Fochler 2008). This prompted STS scholars to reject the notion of a single ‘public.’ Instead, they emphasize multiple, context-specific publics (Warner 2002; Marres 2007). For example, Pesch et al. (2020) advocate forming dedicated ‘local publics’ so that acceptability is judged by diverse community stakeholders (including local communities) rather than an abstract general public, reflecting the co-production of knowledge and values (Witjes 2017). In short, contemporary literature suggests that meaningful pTA must engage various publics rather than treat participation as a one-size-fits-all or token gesture.

Security conditions create further challenges. Democratic theory holds that participation only matters when processes are transparent, inclusive, and answerable to citizens (Habermas 2001; Dryzek 2002). But secrecy in defense policymaking directly conflicts with these ideals. Analysts warn that secret policymaking produces a ‘knowledge deficit’ and prevents citizens from authorizing or contesting hidden actions (Mokrosinska 2023), while withholding information in military affairs erodes citizen consent (Perthes 2011). Appeals to ‘necessary secrecy’ may even cloak unethical practices (Born and Leigh 2007). Under such conditions, participatory exercises risk being purely symbolic. When urgency and confidentiality dominate, public forums tend to rubber-stamp pre-set outcomes (Taylor et al. 2017). In military contexts these pressures intensify: Secrecy is woven into operations (Mickan 2013) even as life-and-death technologies arguably demand popular scrutiny. Overall, scholars conclude that confidentiality requirements routinely undermine accountability, often relegating participation to a thin veneer that deepens public exclusion (Guerrero 2018).

Research on emerging military technologies shows that narrative framing also plays a performative role. Malmio (2023) finds that debates on AI (e.g., Project Maven) are framed by competing ‘enabling’ narratives (AI as life-saving precision tool) versus ‘constraining’ narratives (emphasizing human accountability), and that these frames actively shape technological trajectories by defining which ethical choices seem possible. More broadly, foresight studies note a consensus among experts on the need for civilian engagement in security innovation, but lament a lack of concrete participation models for defense (Vicente-Oliva 2025). As Hennen et al. (2023) and Ladikas et al. (2023) argue, transnational security challenges strain national TA designs, calling for new, cross-border engagement frameworks beyond the nation-state.

Nonetheless, informal or insurgent forms of influence can emerge. Whistleblowers, media exposés, or employee activism sometimes thrust hidden military R&D into public view. Lindelauf and Meerveld (2025) propose ‘hybrid’ transparency arrangements (for example, keeping military AI algorithms closed to the general market but open to audit by vetted, trusted partners) to build trust without fully sacrificing confidentiality. The Project Maven case exemplifies the limits of such bottom-up contestation: Google employees’ protests forced the company to withdraw (imposing an internal pause and ethical commitment), but the Pentagon’s AI program continued largely as planned (Xue and Guo 2024). Thus, while these episodes can expose value conflicts and impose constraints on some actors, entrenched secrecy and power asymmetries often mean that underlying innovation trajectories remain unaffected.

This paper follows a qualitative case study design using Project Maven as an example. This case study was selected because Project Maven is a prominent current example of the intertwining of high technology and the security apparatus, and it can be partially reconstructed through public documents and debates. The case thus provides empirical insights into otherwise difficult-to-access processes at the interface between the technology industry and the military. At the same time, Maven paradigmatically illustrates the thesis of the tension between (symbolic) participation and democratic conflict potential.

The analysis is divided into two steps: First, a comprehensive literature review was conducted, bringing together theoretical and conceptual foundations from the fields of TA, security research, STS, and democracy theory. Second, primary and secondary sources on the Project Maven case were evaluated. To this end, the available sources were systematically recorded: official government documents (e.g., reports from the U.S. Department of Defense and analyses from the Congressional Research Service), parliamentary hearings and debate contributions, press articles (international and US-internal, 2017–2024), reports from non-governmental organizations and think tanks, and public statements by the companies and actors involved (e.g., blog posts by Google executives, the published corporate mission statement on AI ethics, open letters from employees). The identified documents were examined using qualitative content analysis. Key events and decisions in the course of Maven were chronologically reconstructed, identifying key actors (Pentagon, Google management, Google employees, media, politicians) and their contributions to the discourse. Particular attention was paid to informal forms of participation (such as employee protests) and the institutional framework (e.g., the role of internal company forums vs. the lack of government participation formats). The case analysis is theory-driven: It embeds the empirical findings in discussions about participation and democracy in order to make empirical and normative classifications.

Research in security policy contexts poses specific methodological challenges. Much of it takes place in areas that are closed to the public; relevant documents are often subject to high levels of secrecy. The present study therefore relies on publicly available information. This entails limitations: The presentation is based on what has come to light (e.g., through media reports). It is naturally impossible to obtain a complete picture of internal decision-making processes at the Department of Defense or Google. In addition, the statements made by the actors must be viewed in the context of their possible self-interests (e.g., corporate statements may be strategically motivated). To counteract distortions, source triangulation was attempted: Wherever possible, information is corroborated by several independent sources (e.g., press reports are compared with official statements and subsequent analyses). Nevertheless, the results must be interpreted with the caveat that they primarily reflect publicly documented dynamics. These limitations are disclosed in the discussion in order to make the scope of the conclusions transparent.

The Project Maven case highlights institutional, epistemic, and power-political barriers that restrict genuine participation in security innovation. Institutionally, there is a deep asymmetry between the security apparatus and the democratic public sphere. Military and intelligence agencies operate within a closed ‘security zone,’ shielded by secrecy rules, clearances, and black budgets that place decisions beyond public control. As Mickan (2013) notes, secrecy is a constitutive element of the military, yet this tension must not come at the expense of informed citizens. In Maven, no formal participation took place – basic information such as data use or algorithmic design remained classified. The only ‘participants’ were Google employees, whose protest mattered mainly because Google’s public brand and dependence on skilled labor gave them leverage. By contrast, traditional defense contractors face no comparable pressure; their activities usually remain invisible and only surface through leaks or media scrutiny.

Epistemically, knowledge asymmetries further block participation. Maven’s AI systems functioned as a black box: Neither internal actors nor the public knew how models operated or what data they used. Without technical transparency, meaningful debate is impossible. Even Google staff demanding insight into the project met resistance, while external observers had no access to relevant facts. As Lindelauf and Meerveld (2025) argue, limited openness toward trusted partners could strengthen accountability, but under current secrecy regimes participation remains largely superficial. The epistemic gap between experts with clearance and lay publics thus widens, reinforcing perceptions of incompetence on the latter’s side.

Without technical transparency, meaningful debate is impossible.

Power-political barriers arise when urgency and threat narratives justify exceptional measures. In the Maven debate, references to a technological race with China served to sideline democratic procedures – a typical case of securitization. Born and Leigh (2007) warn that such appeals to ‘necessary secrecy’ can mask dubious practices. The decision to partner with Google was driven by efficiency, not public deliberation. Civil society’s influence was indirect: Only when reputational risk threatened Google did management react. As Vicente-Oliva (2025) notes, experts call for more citizen involvement in defense foresight, yet no concrete models exist. Maven confirms that participatory impulses remain extra-institutional and symbolically charged.

To address these tensions, several reforms have been proposed. Advisory boards with security clearance could review classified projects while representing diverse perspectives, though confidentiality risks curbing critique. Confidential parliamentary hearings might allow selected experts and NGOs to advise defense committees behind closed doors, using existing democratic channels but offering limited public transparency. Simulated citizen forums could model deliberation through hypothetical scenarios, though their policy impact would remain uncertain. Each approach faces resistance from security institutions reluctant to share authority. Yet incremental steps (such as independent ombudsmen or periodic public reports on defense AI) could create ‘embedded transparency’ without endangering operational secrecy.

Overall, the Maven protests exposed systemic tensions rather than resolving them. Participation under secrecy remains ad hoc and largely symbolic: It can illuminate value conflicts but rarely transforms underlying power structures or decision-making in security policy.

PTA in security governance often remains largely symbolic because secrecy, urgency narratives, and hierarchical power structures render transparency and inclusion difficult. However, the Project Maven case illustrates that critical contestation can still emerge. Protests of these effects are contingent and fragile – Maven’s AI project continued under other contractors, showing that symbolic resistance rarely changes structural power asymmetries. In sum, pTA in the security sector remains constrained but not futile: Even symbolic participation can become politically productive when moments of contestation are harnessed to uphold democratic oversight and accountability.
