Human Forces in Engineering
About This Book
This book aims to provide engineers with an overview knowledge of disciplines such as sociopolitics, psychology, economics, and leadership.
Engineers are disproportionately represented in senior management and in leadership roles, and many work outside typical engineering roles. Vital to their success are technical skills, but also, crucially, an understanding of the societal setting within which engineering takes place. Engineers that leverage their technical and analytical abilities with an understanding of the social context are enormously successful, both professionally and in terms of broader impact.
This book originated from a recognition that this capacity of engineers can be enhanced with an understanding of the 'human forces', the phenomena that underpin and govern human interactions. The key ideas were assembled with domain experts from each field, to provide the key critical insights and how these might be practically applied by engineers. The authors provide the basis for the learning necessary to guide high-level strategic decisions, manage teams of diverse skillsets in complex environments, communicate in the context of management and decision-making, and to excel at the interface between a technical discipline and non-scientific fields.
Prof. Andrej Atrens is Professor of Materials Engineering at The University of Queensland (UQ). He has experience in Universities and Research Institutes in Switzerland, Thailand, Canada, France, Germany, Sweden, China, USA, Fiji and Australia.
Dr. Aleks Atrens is an Honorary Research Fellow at The University of Queensland (UQ). He earned his BE (Hons) in Chemical Engineering in 2007, and his PhD in 2011, both at UQ, where he has subsequently been a lecturer and researcher.

Information
Psychology
- A useful model for human cognition is that judgements involve two modes of thinking: a fast, effortless, reflexive or intuitive mode of thinking (System 1), and a slower, effortful, and deliberative mode of thinking (System 2).
- System 1 thinking relies on learned associations (heuristics) to make fast decisions from limited information. It is very powerful, but is also prone to a range of errors (biases). As a consequence, human judgement in general is prone to characteristic errors.
- Expertise is the capacity to make accurate and useful judgements in a specific domain. An expert can integrate their experience and situational cues to quickly envisage a likely answer, or a path forward to make progress on a solution.
- Expertise can be developed only in an environment with regular and valid cues, and is based on extensive experience using these cues for rapid and accurate feedback. Expertise may be difficult or even impossible to develop in chaotic environments with low-quality feedback (high noise to signal ratio), or long delays between action and feedback.
- Expertise is domain-specific. Application of expertise across domains can be misleading, as confidence in oneâs judgement is a poor indicator of accuracy and it can be difficult to distinguish between useful and useless intuitive judgements.
- Social identity theory states that people define themselves not only in terms of âIâ (as individuals), but also in terms of âweâ (as members of social groups). Every individual has many group memberships and thus many social identities. When team members endorse and work for the benefit of a shared social identity, they will better coordinate their actions and are more likely achieve shared success.
- A strong shared social identity can be a double-edged sword. We care about a social identity like we care about our personal identities. We will seek to uphold, protect, or enhance our groupâs beliefs and values. Upholding a groupâs values and distinctiveness may be positive in that it promotes coordination and good behaviours within a group. But it can also be negative in that protecting your groupâs values and distinctiveness may mean conflicts with other groups.
- The psychological view of leadership is determined by the context of the group, including the groupâs shared social identity and purpose, its internal structure, and the environment within which the group operates (e.g., other competing or cooperating groups, availability of resources). This view differs from the traditional concept of leadership as arising from traits or behaviours such as power or charisma.
- A leader in the psychological sense represents the groupâs interests to other groups, makes decisions on behalf of the group regarding its purpose/goals, actions to attain the goal, and persuades group members to contribute to achieving the groupâs goals.
- Leadership is conferred by followers and is maintained by successfully leading the group. Leadership is likely to be lost by acting against the interests of the group, deviating from group norms, or not advocating for the groupâs goals to those outside the group.
- Humans are embedded in every engineering system. A system may appear technically reliable but be vulnerable to unexpected external hazards beyond the scope of its design.
- Existing safety approaches tend to design ever more complex engineering controls to remove or restrict human âerrorâ in a system. It may also be vulnerable to unexpected internal hazards if its design does not account for the bounded rationality, and group dynamics of its operators.
- A human factors approach seeks to incorporate a psychological understanding of how humans interact with designed systems to improve performance and safety.
- Resilience engineering recognises that the human operator exists to provide resilience and adaptability and seeks to empower them to act appropriately in a system.
