The core finding is that social features, when designed with a nuanced understanding of human psychology, can be powerful catalysts for positive and sustained behaviour change. However, a naive,"one-size-fits-all" approach is not only ineffective but carries significant psychological risks.

The analysis reveals a critical distinction between competitive and collaborative social mechanics. Competitive features, such as leaderboards, are most effective at driving short-term performance and personal growth. In contrast, collaborative features, like team-based challenges, excel at fostering long-term user engagement and increasing life satisfaction.³The effects of these features are highly heterogeneous; leaderboards, for instance, can be remarkably motivating for sedentary users but can paradoxically decrease the activity levels of already highly active individuals.⁴

‍

This heterogeneity underscores the potential harms of poorly implemented social comparison. Constant exposure to idealizsd performance and body images can fuel anxiety, body dissatisfaction, and disordered eating behaviours, particularly among vulnerable users.⁵ Therefore, an ethical, user-centric design philosophy is not merely a best practice but a critical necessity.

The strategic recommendations presented in this report advocate for a shift away from simplistic, universal social features toward a personalized and collaborative model. The most effective platforms will empower users with control over their social experience, prioritise team-based, positive-sum interactions, and carefully design "safer" competitive elements that mitigate negative psychological outcomes.

By understanding that the true power of peer influence lies in normalising average, achievable behaviours rather than showcasing elite performance, health platforms can build supportive communities that help all members become healthier, more engaged versions of themselves.

The Psychological Foundations of Peer Influence

1.1 The Drive to Compare: Festinger's Social Comparison Theory

The theoretical bedrock for understanding peer influence isSocial Comparison Theory, first proposed by social psychologist Leon Festingerin 1954. The theory posits that humans have an innate and fundamental drive to gain accurate evaluations of their own opinions and abilities.¹ When objective, non-social standards are unavailable, individuals turn to others asa benchmark to reduce uncertainty and define the self.¹ This processis not a passive observation but an active form of measurement and self-assessment that helps individuals understand where they stand relative toa reference group.¹

Core Motivations and Directions of Comparison

While Festinger's initial work focused on the drive for accurate self-evaluation, subsequent research has expanded the motivations for social comparison to include three primary drives ⁷:

1. Self-Evaluation: The need to understand one's own capabilities and the correctness of one's  opinions. For this purpose, individuals tend to seek out comparison targets who are similar to themselves, as this provides the most realistic  and salutary information.¹
2. Self-Enhancement: The desire to feel better about oneself and protect self-esteem. This  often involves strategic comparisons designed to produce a favourable  outcome for the self.¹
3. Self-Improvement: The motivation to grow, achieve, and become better. This drive often leads  individuals to look toward those who are more accomplished for inspiration.⁷

These motivations manifest through two primary directions of comparison: upward and downward.

• Upward   Social Comparison: This occurs when an individual compares themselves  to someone perceived to be superior or performing better. The   psychological outcome of upward comparison is highly dependent on the   individual's mindset and context. It can be a powerful catalyst for positive     change, leading to inspiration, optimism, and motivation to work harder.⁷   However, it can also have profoundly negative effects, eliciting feelings     of envy, resentment, shame, depression, and inadequacy, particularly if  the superior standard feels unattainable.²
• Downward  Social Comparison: This involves comparing oneself to someone   perceived to be less fortunate or performing worse. The most common   outcome is a boost in self-esteem and feelings of pride or gratitude for one's own situation.⁷ The potential negative consequence is the     development of arrogance, scorn, or a sense of complacency that stifles   motivation for further improvement.

The complex emotional landscape of these comparisons is critical for designers of social systems to understand, as any feature that facilitates comparison will inevitably trigger this spectrum of responses.

The Critical Role of Similarity and Group Dynamics

‍

Festinger's theory emphasizes that the choice of a comparison target is not random. One of his core hypotheses states that the tendency to compare oneself to another person decreases as the difference between their opinions and abilities becomes more divergent.¹ In other words, individuals are less likely to compare themselves to someone they perceive as fundamentally different. This "similarity principle" is a cornerstone of effective social influence. When a comparison target is deemed too different, the information they provide is dismissed as irrelevant, and themotivational force of the comparison is lost.

Furthermore, Festinger hypothesizsed that an individual's tendency to change their behaviour is influenced by their distance from the group's mode, or average. Those who are closer to the group's average have a higher tendency to conform, while those who are outliers are less likely to change.¹

This suggests that the power of a peer group lies in its ability to establish a "normal" range of behaviour, creating implicit pressure on members near that norm to align with it. The combination of these principles—the preference for similar comparison targets and the pressure to conform to a group average—forms the psychological basis for designing effective peer groups in any social system, including health and wellbeing platforms.

A platform that groups users randomly or creates leaderboards with vastly different performance levels will fail because the comparisons will be perceived as irrelevant. To be effective, social features must be built around carefully constructed peer groups based on factors like initial fitness level, age, or stated goals to maximise the perceived similarity and, consequently, the motivational impact of the comparison.

1.2 From Envy to Emulation: The "Keeping Up with theJoneses" Effect

The most culturally resonant manifestation of social comparison theory is the phenomenon known as "keeping up with theJoneses." This concept connects the abstract psychological drive to compare with tangible, real-world behaviours, particularly in the realm of consumption. Its intellectual roots can be traced to sociologist ThorsteinVeblen's 1899 theory of "conspicuous consumption," which described the acquisition of goods and services primarily for the purpose of displaying wealth and social status.¹⁰

While Veblen's work focused on the visible display of luxury items, modern economic research has refined this understanding, suggesting a more subtle but pervasive mechanism is at play. James Duesenberry's"relative income hypothesis," proposed in 1948, argued that the strength of an individual's desire to increase their consumption is a function of the ratio of their expenditure to a weighted average of the expenditures of others in their reference group.¹⁰

Recent empirical studies have tested these competing models and found robust support for Duesenberry's formulation. The primary driver of the "keeping up with the Joneses" effect is not the desire to purchase conspicuous, luxury goods, but rather the impulse to match the average consumption of one's peers.¹⁰

^‍ This distinction is critical. The effect is not about status-seeking through visible luxury but about conforming to the perceived norm of a reference group. This pressure to keep up leads to a significant inter-temporal distortion of spending profiles, causing individuals to under-save or over-borrow to maintain a lifestyle consistent with their peers.¹⁰ The phenomenon is particularly potent when the peer group is tightly defined by shared characteristics like education, age, and occupation.¹⁰

In the digital age, this effect has been amplified. Socialmedia platforms create a vastly expanded and curated peer group, where individuals compare their own lives to the "highlight reels" of others, leading to skewed perceptions and increased pressure to consume.¹³Furthermore, the nature of what is being compared has evolved. Research indicates a shift from purely material possessions to experiences, with activities like travel becoming the new markers of status and success among certain cohorts.¹¹

This body of research provides a powerful lesson for the design of health platforms. The logic that drives consumption patterns can be directly translated to health behaviours. The most potent form of social influence is not showcasing elite performance—the health equivalent of a luxurycar—which is unrelatable and often demotivating for the average person

.Instead, the real power lies in making the average, consistent behaviours  of a user's similar peer group visible. This shifts the user's internal calculus from an intimidating upward comparison ("I can never be like that super-athlete") to a process of normalisation ("This level of activity is the achievable standard for people like me"). By focusing on he "average" rather than the "conspicuous," platforms can leverage the deep-seated human need to conform to group norms to foster sustainable, positive health habits.¹⁵
