Aim

Complexity science studies how a large collection of components – locally interacting with each other at small scales – can spontaneously self-organize to exhibit non-trivial, unpredictable global structures and behaviors at larger scales, often without external intervention, central authorities, or leaders. Characteristics of these systems, such as having non-linear emerging dynamics and being adaptive, pose unique ethical challenges, as traditional normative ethical approaches often struggle to account for such dynamic and intricate interactions. At the same time, complexity science methodologies are widely used in many applications with daily life impacts, e.g., climate change, financial markets, healthcare, polarization, and technological networks. However, ethical considerations often lag, leaving critical gaps in understanding the broader research implications in this area.
This one-day interdisciplinary workshop aimed at bridging the gap between researchers in complexity science and ethics. This will feature sessions led by complexity researchers presenting their work, emphasizing why ethical considerations are necessary in their research. In parallel, ethicists will introduce various ethical theories and methods that can be adapted to tackle the unique challenges of complex systems. The workshop aims to develop a shared language and possibly new frameworks that integrate ethics into studying and managing complex systems by facilitating discussions between these communities.

Too complex to be good? On the nature and moral significance of complexity

What is complexity and why is it morally relevant?

Technological innovations such as new AI tools, but also political proposals to address broader challenges for society tend to be increasingly complex, and this seems to constitute a challenge of its own. However, what exactly do we mean when we talk about complex solutions, and why is complexity a problem? This lecture aims to answer these questions. It first draws on recent accounts of complex systems to explicate the complexity of technological solutions. I then discuss arguments that purport to show why complexity is pro tanto bad and propose to systematize them. The arguments have it that complex systems are more costly, lack transparency, render the ethics too complex, and contribute to a loss of human autonomy. I argue that not all of these arguments are persuasive and that the moral status of complexity depends on the kind of complexity and the level on which it unfolds.

Responsible computing with societal data: how methodological choices shape our understanding of complex systems

The modeling choices we make when analyzing and predicting complex socio-technical systems shape our knowledge and theories about the functioning and behavior of societies. For example, many of the social science theories that we use to explain empirical findings were identified decades ago based on observing small- to medium-sized groups over long periods of time. More recent findings about societal systems are based on analyzing large-scale data that cover shorter time spans. Such differences in research design have led to the development of culturally contextualized algorithms that impact knowledge discovery and theory development. I discuss implications of research design on the validity of our understanding of society and strategies for the detection and mitigation of error propagation.

Machine Learning for Social Good: Algorithmic & Data Challenges when working with Vulnerable Populations

The scale, reach, and real-time nature of the Internet is opening new frontiers for better serving humanity, and particularly for a deeper understanding of the vulnerabilities in our societies, including inequalities and fragility in the face of a changing world. Vulnerable populations including children, elderly, racial or ethnic minorities, socioeconomically disadvantaged, underinsured, or those with certain medical conditions, are often absent in commonly used data sources. The aim of this talk will be to shed light on data and algorithmic biases, as well as methodological particulars when addressing vulnerable populations, drawing insights from case studies in response to real humanitarian crises.

On the ethics of disaster impacts: data collection, analysis and modelling

For millennia, the term ‘natural disasters’ has been used by monarchies and governing bodies around the world to shed responsibility for impacts of hazards such as earthquakes and floods. Such disasters continue to produce a large number of deaths, infrastructural and agricultural damage as well as significant population displacement every year. Although the hazard itself may be considered natural, with good governance, planning and preparation, the impacts of such hazards can be significantly reduced. However, we must integrate social equity into all approaches taken to reduce impact. Do we collect data on how disasters have differentiated impacts depending on gender, class, ethnicity and other factors? Do disaster alert systems take into account the needs of different population groups in the hazard-exposed area such as language or income? Have governments stopped using disasters as a political tool? No. This presentation will explore the ethics of disaster impact data collection, analysis and modelling, based on working within United Nations and International Non-Government Organisations over the past few years.
