An engineer, a physician, and a historian may appear to represent distinct fields across the divide between science, technology, engineering and mathematics (STEM) and the humanities, but all three share foundational skills such as critical thinking, problem framing, evidence evaluation, and collaborative communication. In a joint essay, three Singaporean experts—Janil Puthucheary, Senior Minister of State for Education and Sustainability and the Environment; Ho Teck Hua, president of Nanyang Technological University; and Tan Tai Yong, president of Singapore University of Social Sciences—argue that contemporary challenges require bridging this traditional divide through multidisciplinary approaches enhanced by artificial intelligence (AI).
The authors highlight that while formal education and professional identities often segment individuals into technical or verbal, quantitative or creative categories, the realities of the modern world demand fluency across disciplines. Complex societal issues—ranging from climate adaptation and urban planning to digital regulation—cannot be adequately addressed within the confines of a single field. For example, climate resilience depends not only on engineering models but also on economic, behavioural, and ethical considerations, while digital policy requires an understanding of both software systems and market dynamics.
The essay does not suggest erasing the distinctions or depth of disciplinary expertise. Instead, it advocates for a “second bilingualism”—akin to Singapore’s long-standing bilingual language policy—where individuals maintain mastery of their primary domain while acquiring working knowledge in complementary fields, particularly AI. The authors contend that AI presents an opportunity to dissolve rigid disciplinary boundaries because understanding and applying AI draws upon mathematics, computer science, linguistics, philosophy, ethics, law, and domain-specific knowledge all at once.
To cultivate this integrative mindset, tertiary education institutions are encouraged to reform curricula and assessment methods. Students should be evaluated not just on knowledge within a subject area but on their ability to frame problems using evidence from multiple disciplines, recognize the limits of different methods, and synthesize diverse perspectives into sound judgments. The authors emphasize that this does not require creating new omnibus subjects or expecting students to become experts in all fields; rather, it calls for structured opportunities to work across disciplinary lines through coordinated teaching efforts.
The essay underscores that developing multidisciplinary fluency is a gradual process, involving repeated engagement near the edge of current competencies to build judgment over time. By embedding such learning experiences within higher education, Singapore can build a workforce and leadership capable of collaborative problem-solving that preserves disciplinary depth while enhancing cross-field synergy.
Ultimately, the authors argue that the future requires professionals—whether engineers, historians, or physicians—who can confidently engage with other fields, ask informed questions, and make collective decisions that address the complex, interconnected challenges of the 21st century.
