Many of you may recall the early stages of the Covid pandemic, when people began panic buying, emptying the shelves of even the largest supermarkets on the island. While fear and uncertainty were the main drivers for such behaviour, herd mentality led many to suspend judgement and follow the crowd despite the consequences, including creating scarcity for vulnerable members of society such as the elderly or less privileged.

Herd mentality, also known as group mentality or groupthink, describes the tendency of individuals to adopt the beliefs, emotions, or actions of a larger group, often without questioning them. From viral social media trends and consumer fads to financial bubbles, the herd mentality shapes decisions in ways that can be both useful and dangerous. Understanding herd mentality helps us see how belonging, fear, uncertainty, and social pressure can influence human behaviour, and why independent thinking is so crucial for the wellbeing of individuals and society.

So, why do people sometimes ignore their own judgment and follow the crowd?

• Human need to belong - Being part of a group once meant greater chances of survival, so belonging has evolutionary roots. Although modern life no longer presents the same threats our predecessors faced, feeling part of a community still provides emotional and physical safety. Groups naturally develop shared norms, beliefs, and values through stories, traditions, and repeated experiences. Over time, these become accepted as truths. This process occurs in organisations, schools, communities, and any setting where people come together. Within these groups, standards of acceptable behaviour are established, with those who align with them welcomed, and those who do not, often finding themselves excluded. Not conforming, therefore, may lead to exclusion and/or rejection.
• Conflict avoidance - It takes courage to resist the pull of the majority or to voice an opinion you know is held by only a few. Consider group polls or feedback sessions, where everyone must express their opinion/decision to the group. Even when someone disagrees with the majority choice, they may begin to doubt their own judgement or align their vote/feedback with the majority simply to avoid the internal discomfort, or the external tension that can come from standing apart from the herd.
• Social influence - As inherently social beings, we tend to look to others for direction and reassurance, especially when our own knowledge or experience is limited. The problem arises when we assume that others are acting on accurate information. This can prompt us to follow their lead uncritically, allowing beliefs or behaviours to spread quickly, even when they are misguided or harmful.
• Tendency to take mental shortcuts - It's easier to rely on the views of others rather than taking the time and energy to carry out research on a topic and then think critically once you've done the necessary research.

The herd mentality does offer advantages, especially when individual knowledge or expertise is limited. A group's collective experience can be far more reliable than what any one person knows alone. This becomes particularly valuable when prompt action is required or when maintaining group cohesion is essential for achieving a shared objective. However, the herd mentality also poses a number of drawbacks, including:

• Loss of critical thinking - When people follow the group, they often suspend independent judgement, resulting in decisions which are reactive rather than reflective. Keep in mind also that critical thinking is a skill which develops and improves through practice. Therefore, when we simply accept group norms and beliefs without questioning or challenging them, we slowly erode our ability to ask the right questions, evaluate, analyse and make a judgement which is fair, ethical and reflective.
• Inaccurate risk perception - Individuals may underestimate danger because "everyone else is doing it", leading to risky behaviours that would normally be avoided. One example involved the housing bubble which occurred between 2006-2012 in the US, whereby people invested simply because "everyone else was". The collective enthusiasm inflated prices far beyond reality, and when the bubble burst, millions suffered financial loss.

• Loss of individuality - People may disregard their own views, values, or instincts to avoid standing out. Over time, this can erode confidence and personal agency, as individuals become more concerned with fitting in than with forming or expressing their own opinions. This is especially predominant in online spaces, where trends, opinions, and behaviours can spread rapidly. Someone may adopt a style, belief, or attitude not because it genuinely reflects who they are, but because it is what the group appears to approve of. When this happens repeatedly, people may lose touch with their own values, beliefs and preferences in favour of conforming.
• Rapid spread of misinformation - When assumptions are made based on others' actions rather than verified facts, inaccurate beliefs can spread incredibly quickly. Take, for instance, if an individual posts a short video clip showing a person behaving in a way that appears harmful or unethical. The clip would most likely lack context, yet commenters assume wrongdoing and express anger and disapproval regardless. Repetitive sharing without fact-checking can be very harmful for the person/s implicated in the online clip.

• Pressure to conform - Fear of judgement, exclusion, or conflict can lead individuals to follow the majority even when it contradicts their own knowledge or values. A clear example is online bullying. Bystanders may witness the abuse yet remain silent, not because they agree with it, but because they fear becoming targets themselves.
• Reduced accountability - When everyone is doing the same thing, responsibility becomes diffused, resulting in individuals feeling less personally accountable for harmful actions.
• Stagnation and resistance to change - Herd mentality favours the familiar. Innovation, dissent, and new perspectives are often discouraged, limiting growth and adaptation.

Reflecting on the concept of herd mentality reminds us of our inherent need to belong and be accepted. By being aware of the risks associated with blindly following the herd, however, we can start pausing, questioning, and choosing responses or actions which align with our own values rather than the pull of the crowd.
