New research unveils the "dark side" of social media influencers and their impact on marketing and consumer behaviour

Social media influencers (SMIs) pose psychological, health and security risks and need tighter regulation, a new study finds.

SMIs have revolutionised marketing, shaping consumer behaviour, brand strategies, and even societal norms. However, new research exposes a lesser-known side of influencer culture, one that raises ethical, psychological, and regulatory concerns.

A recent study by the University of Portsmouth systematically examines the negative impacts of SMIs, highlighting issues such as misinformation, endorsement of dangerous products, unrealistic beauty standards, the fostering of a comparison culture, deceptive consumption, and privacy risks.

With influencer marketing projected to reach an estimated $480 billion by 2027, companies increasingly rely on SMIs to promote products and foster consumer trust.

A Digital Marketing Institute (2024) survey found that 60 per cent of consumers trust influencer recommendations, with nearly half of all purchasing decisions being influenced by these endorsements. However, as influencer culture grows, so do concerns about its unintended consequences. 

Many SMIs act as opinion leaders or experts within their respective areas, frequently reviewing products and leveraging their authority, expertise, or relationships with followers to influence purchasing decisions. Some inspire and entertain; others deceive and upset. The deception and damage, and their impact on consumption, need to be carefully regulated.

The paper, published in Psychology and Marketing, warns power of SMIs is creating a worrying consumer landscape. Unlike traditional celebrities, whose fame is typically rooted in institutional settings - such as acting, music, or sports - SMIs gain recognition through social media platforms, often relying on personal branding and consistent engagement with their audiences.

Yuksel Ekinci, Professor of Marketing and Sales at the University of Portsmouth, said: "Many SMIs act as opinion leaders or experts within their respective areas, frequently reviewing products and leveraging their authority, expertise, or relationships with followers to influence purchasing decisions. Some inspire and entertain; others deceive and upset. The deception and damage, and their impact on consumption, need to be carefully regulated."

This study organises the negative aspects of influencer marketing into six key themes:

1. Promotion of harmful products − SMIs often endorse unhealthy or dangerous products such as diet pills, detox teas, and alcohol without full disclosure, influencing consumption habits, particularly among younger audiences.

2. Dissemination of misinformation − many influencers, despite lacking expertise, spread false information about health, politics, and social issues, leading to widespread disinformation.

3. Reinforcement of unrealistic beauty standards − by presenting filtered and curated images, influencers contribute to body dissatisfaction, low self-esteem, and harmful beauty practices.

4. Fostering of comparison culture − influencer-driven content fuels lifestyle envy and social anxiety, leading to negative self-comparison and diminished wellbeing.

5. Deceptive consumption practices − some influencers engage in unethical behaviours such as undisclosed sponsorships, promotion of counterfeit goods, and misleading advertisements, undermining consumer trust.

6. Privacy concerns − the extensive data collection and sharing by influencers raise significant security and regulatory issues, posing risks for both influencers and followers.

Social media influencers hold immense power over consumer decisions and cultural norms. While they provide entertainment, inspiration, and brand engagement, the unchecked influence of some SMIs can lead to serious ethical and psychological consequences. Our study highlights the urgency for both academic and industry stakeholders to address these challenges proactively.

The study calls for more stringent oversight, increased transparency, and ethical marketing strategies to mitigate these risks. Researchers suggest the following strategies for policymakers and marketeers:

Transparency and ethical compliance: brands must enforce clear disclosure policies to ensure responsible influencer partnerships. 

• Regulation and consumer protection: governments should strengthen policies on influencer marketing to prevent deceptive practices and misinformation. 

• Mental health awareness: companies and influencers must prioritize authentic content that promotes well-being rather than unattainable ideals. 

• Data privacy protections: stronger safeguards and awareness campaigns are needed to protect users from privacy breaches and data exploitation.

Dr Georgia Buckle, Research Fellow in the School of Accounting, Economics and Finance at the University of Portsmouth, said: "Social media influencers hold immense power over consumer decisions and cultural norms. While they provide entertainment, inspiration, and brand engagement, the unchecked influence of some SMIs can lead to serious ethical and psychological consequences. Our study highlights the urgency for both academic and industry stakeholders to address these challenges proactively."

This research offers a critical framework for analysing influencer culture beyond its commercial benefits, emphasising the need for ethical marketing practices and a healthier digital ecosystem.

Gabarito: A

Fundamento decisivo: O enunciado já indica que o artigo combina precisão científica com acessibilidade midiática. O ponto decisivo é reconhecer que essa persuasão se apoia na alternância entre vozes autorizadas e evidências factuais, o que sustenta a alternativa A.

Tema central: autoridade retórica híbrida
Análise das alternativas
A
Certa
A alternativa A descreve o mecanismo persuasivo central: citações de especialistas, referências institucionais e dados/fatos objetivos. Isso produz credibilidade da fonte e sustentação factual do argumento, ao mesmo tempo em que mantém a acessibilidade do texto para o público amplo.
B
Errada
Está errada porque o texto não se apoia em ambiguidade semântica para convencer. Ao contrário, ele delimita os problemas de modo explícito, com categorias enumeradas e formulações diretas, reduzindo incerteza em vez de provocá-la.
C
Errada
Está errada porque, embora existam termos avaliativos pontuais como dark side e worrying, isso não constitui o mecanismo central de persuasão. A força argumentativa principal vem da credibilidade construída por especialistas, instituições e dados, não de dramatização lexical predominante.
D
Errada
Está errada porque o texto não se estrutura por metáforas nem por identificação emocional com o estilo de vida dos influenciadores. Sua base é expositiva-argumentativa, sustentada por referências acadêmicas, enumeração de riscos e explicitação analítica.
Pegadinha da questão
A confusão real era tomar a presença pontual de adjetivos avaliativos como se o texto fosse sensacionalista, quando o enunciado já sinaliza que a autoridade vem da combinação entre precisão científica, fontes especializadas e acessibilidade.
Dica para questões semelhantes
  • Quando a questão perguntar sobre autoridade do texto, procure primeiro quem fala, com qual vínculo institucional e com qual tipo de evidência.
  • Se o enunciado destacar discurso híbrido, verifique se a persuasão nasce da combinação entre credibilidade técnica e linguagem acessível, não de emoção ou ornamentação.
  • Diferencie recurso secundário de mecanismo central: adjetivos avaliativos podem aparecer, mas só decidem a questão se estruturarem a persuasão.
  • Enumeração, dados, estudo citado e fala de especialista costumam sinalizar articulação de logos com ethos.
