Understanding Why People Behave the Way They Do

Executive Summary • Traditional approaches to learning, culture and organisational change often overestimate the role of conscious reasoning in shaping behaviour.

• Gaps between awareness, intent and action persist because behaviour is influenced by forces operating largely beyond conscious awareness .

• Decisions are often made in seconds or milliseconds, and behaviour responds more strongly to context, cues and environmental design than to information alone.

• Motivation is shaped less by rewards and more by anticipation , reinforcement and the experiences embedded into organisational life.

• As AI transforms the workplace, organisational performance will hinge on systems that align with human behaviour rather than attempting to override them .

. In a world where organisations are constantly adapting to change, understanding how the human brain works has never been more critical. Breakthroughs in neuroscience are offering powerful new insights into why people think, decide and behave the way they do – insights that can redefine how leaders inspire, influence and drive transformation. Businesses would be better placed with a grounding of the science that underlies why people behave the way they do, and why many organisational interventions fail to produce the outcomes they intend.

A good analogy from the history of the telescope, he observed that while Hans Lippershey is credited with inventing the instrument, Galileo transformed its usefulness by pointing it towards the sky rather than distant ships. In a similar uncertain environment, organisations need to examine familiar challenges from a different angle. He argued that most organisational problems are ultimately rooted in human behaviour, yet continue to be approached through models that assume information directly shapes action, even though behaviour is often driven by forces operating beyond conscious awareness.

Why Information Rarely Changes Behaviour Learning interventions, leadership communication, values campaigns and engagement initiatives are all designed on the assumption that information influences behaviour in a predictable manner. The persistence of behavioural challenges, however, suggests a structural gap between knowledge and action. Across contexts, individuals often understand what is expected of them and recognise the consequences of ignoring it, but their behaviour may diverge from what those expectations imply. Employees may understand organisational priorities, leadership expectations or cultural values, yet continue to behave differently. The challenge, therefore, is often not a lack of awareness, but the mechanisms through which behaviour is translated into action.

Awareness, Intent and the Execution Gap These gaps persist because approaches to behaviour in management, training and policy remain rooted in classical economic and psychological models, which treat individuals as rational and consciously deliberative. Training programs, communication campaigns and research instruments are all designed on this premise. The consistently-high (~75-90%) failure rates of change initiatives suggest that these models systematically overestimate the role of conscious reasoning in shaping behaviour. Antibiotics, for instance, represent some of the most significant breakthroughs in modern medicine, but non-adherence and self-medication demonstrate that the constraint lies in how behaviour is governed in practice, and not in some sort of ‘knowledge deficit’.

Biological Constraints of Decision Making Human decision-making is constrained by biology in ways that organisational models rarely factor in. The brain continuously processes vast amounts of information, while conscious decision-making operates within a narrow bandwidth. Of the millions of bits of information processed each second, only a tiny fraction reaches conscious awareness. Decisions are often made before conscious reasoning enters the frame. In fast-moving contexts such as driving, sports or everyday consumer choice, decisions get made in a matter of milliseconds. Even decisions perceived as complex are often resolved within seconds, usually unfolding outside of any conscious ‘control’. These biological constraints become visible in everyday risk behaviour. Large, fast-moving objects such as trains were invented only recently in relation to eons of human evolution. The human brain has not (yet) adapted to accurately process such threats – which helps explain continued risk-taking at railway crossings or in accident-prone road segments.

Context, Cues and the Moment of Action If behaviour is shaped largely outside conscious awareness, influence must operate where the action occurs rather than where intentions are formed . Communication or training delivered far from the moment of decision therefore has only limited impact. Office layouts, canteen design, workflows, signages and physical movement patterns often exert greater influence over behaviour than formal policies. The organisational culture may consequently be shaped less by values articulated during leadership forums and more by the environments employees repeatedly encounter. Informal interactions, workplace design, team routines and everyday experiences reinforce behaviours in ways that formal communication cannot. The implication is that culture-change efforts may need to focus as much on redesigning contexts as on communicating intentions. The flipside is that modest contextual changes can result in profound behavioural shifts without requiring conscious engagement. Some examples of how the environment becomes the intervention include:

Railway visual markers that align with motion-detection systems dramatically reduce fatalities.

Highway line-spacing that compresses visually creates an illusion of speed and triggers braking.

Motivation, Anticipation and Reinforcement Neurologically, engagement is driven less by the reward itself and more by the anticipation of what might happen. Dopamine surges most strongly under conditions of uncertainty and variable outcomes, which helps explain compulsive smartphone checking and responsiveness to intermittent digital cues. Repeated rituals, recognition practices and organisational narratives can shape expectations and reinforce behavioural norms over time. Culture, in this sense, is often sustained not by formal statements, but through the stories organisations celebrate, the behaviours they recognise and the experiences employees repeatedly encounter. Motivation emerges from the anticipation, reinforcement and emotional associations embedded into organisational life. This implies that:

Predictable annual appraisals dull engagement rather than strengthen it

Variable and intermittent reinforcement sustains behavioural momentum

Curiosity-driven learning outperforms linear content delivery

Immediate recognition outperforms distant promises

Implications for HR Leadership in an AI Age As organisations increasingly deploy AI, behavioural constraints will become even more consequential. Machines process information at extraordinary scale, often with significant energy and environmental costs. The human brain, by contrast, has solved complex problems efficiently for hundreds of millions of years. Influence, in this context, depends on aligning technology with how behaviour actually functions rather than attempting to override it. For CHROs, the challenge extends beyond talent processes and communication programmes towards shaping the conditions under which behaviour occurs. As routine and repetitive tasks become increasingly automated, the ability to understand, influence and reinforce human behaviour may become a more important source of competitive advantage.
