AI Bias in Marketing: Everything You Need To Know

AI Bias in Marketing: Everything You Need To Know

  • On : October 23, 2023

Artificial Intelligence (AI) has revolutionised marketing. The integration of AI tools has ushered in a new era of efficiency, personalisation, and data-driven decision-making. From chatbots to predictive analytics, AI has become an indispensable tool for marketing executives seeking to stay ahead of the curve. However, lurking beneath the surface of these cutting-edge technologies is a critical concern that demands our attention: AI bias.

In this blog post, we’ll delve into the intricacies of AI bias, explore its significance for marketers, and uncover essential insights to navigate AI ethically.

Understanding AI Bias

AI, in the context of marketing, encompasses a wide array of technologies, with one of its most prevalent forms being machine learning. Machine learning models are trained to process vast volumes of data, discern patterns, and make predictions or decisions based on these patterns. This data-driven approach has enabled marketers to create highly targeted strategies, but it also introduces a fundamental challenge: the potential for bias.

The Significance of AI Bias for Marketers

AI bias refers to the systemic errors and prejudices embedded within machine learning algorithms that influence their outputs. These biases can stem from the data used to train AI models, introducing a significant challenge for marketers who rely on these models to inform decisions, predict consumer behaviour, and optimise advertising strategies.

AI bias has the potential to perpetuate stereotypes, alienate target audiences, and, in the worst cases, damage a brand’s reputation. This can have an impact on:

  1. Preserving Brand Trust: If an AI system inadvertently perpetuates discriminatory outcomes or fails to resonate with diverse audiences, it risks damaging the trust carefully built with consumers.
  2. Decision-Making: AI plays a pivotal role in shaping marketing strategies. From segmenting audiences to recommending content, biased algorithms can lead to flawed decision-making. For instance, biased data might cause an AI system to allocate marketing budgets disproportionately, missing out on valuable segments.
  3. Legal Implications: The legal landscape surrounding AI is evolving, and companies face legal consequences if their AI systems are found to be discriminatory.
  4. Customer Experience: In the era of hyper-personalisation, AI helps tailor customer experiences. However, biased algorithms may result in exclusionary or irrelevant content for certain demographics, negatively impacting the customer experience.

What Marketers Need To Know About AI Bias

The foundation of any AI model is the data it is trained on. If this data is skewed or incomplete, the model will inherit and amplify these biases. Biases can also originate from the design of algorithms. For instance, if certain features are given more weight than others, it may lead to skewed predictions. Cognitive bias can also result from assumptions and subjective decisions made during the development process.

Types of Bias:

  • Algorithmic Bias: Bias introduced during the design and implementation of algorithms.
  • Dataset Bias: Bias originating from the training data used to teach the AI system.
  • Cognitive Bias: Bias resulting from assumptions and subjective decisions made during

Impact on Marketing Practice

  • Target Audience Segmentation: Biased data can lead to inaccurate segmentation, causing marketers to miss out on potential markets.
  • Ad Content Personalisation: Personalisation efforts may backfire if AI systems perpetuate stereotypes or fail to understand the diverse preferences of the audience.
  • Performance Metrics: Marketers relying on biased algorithms may receive inaccurate performance metrics, leading to misguided strategies.

AI Bias Reflects Society’s Bias

It’s important to recognise that AI bias is a reflection of society’s biases. AI learns from the data it is fed, and if that data contains societal prejudices, AI models will inherit and reproduce those biases. For example, an image generator may produce images of CEOs that primarily feature white males because historical employment data has shown such a bias.

The fear is that AI has the potential to magnify existing societal biases that are harmful to various groups. Marketers must be aware of this as they work to create inclusive and ethical marketing campaigns.

Examples of AI Bias in Marketing

To truly understand the impact of AI bias in marketing, let’s explore some real-world examples:

  1. Mortgage Approval Rates: AI-driven algorithms in financial institutions are 40-80% more likely to deny borrowers of colour. This bias is rooted in historical lending data that disproportionately denied loans to marginalised groups. Consequently, AI models perpetuate these biases in future applications, leading to discriminatory outcomes.
  2. Amazon’s Recruitment Algorithm: Amazon once developed a recruitment algorithm that was trained on ten years of employment history data. This data, however, reflected a male-dominated workforce. The algorithm was biased against applications from women or any resumes containing the word “women.”
  3. Twitter Image Cropping: In 2020, Twitter’s image cropping algorithm favoured white faces over black ones in picture previews. This bias was starkly evident in how the algorithm consistently cropped images to display white faces.
  4. Robot’s Racist Facial Recognition: A study had robots categorise people based on characteristics, such as doctors, criminals, or homemakers. The robot was biased in its classifications, disproportionately labelling women as homemakers, black men as criminals, and Latino men as janitors.
  5. Intel and Classroom Technology’s Monitoring Software: Intel and Classroom Technology’s Class software have features that monitor students’ emotions while learning. However, these features are fraught with potential for mislabeling emotions due to cultural norms. This could inadvertently penalise students over emotions they’re not actually displaying.

These examples underscore the real-world consequences of AI bias in marketing and highlight the urgent need for marketers to address and rectify such biases in their strategies.

Investing in Ethical AI

AI bias is not a mere technical glitch or abstract concept; it carries significant weight in the marketing realm.  Marketers must take proactive steps to address and mitigate bias in our AI-driven marketing initiatives. Here are some strategies:

  1. Human Oversight: Incorporate human oversight into AI processes. Regularly monitor and analyse outputs, make corrections when biases are detected. Marketers can play a crucial role in scrutinising generative AI outputs before incorporating them into marketing materials.
  2. Assess Potential for Bias: Some use cases for AI in marketing inherently carry a higher potential for bias. Marketers should critically assess the likelihood of their AI systems producing biased results, especially when using historically prejudiced data.
  3. Invest in AI Ethics: Allocate resources for continued investment in AI research and ethics. This investment is essential for developing concrete strategies to reduce and eliminate bias in AI models.
  4. Diversifying AI Teams: Embrace diversity in AI development teams. Different perspectives bring unique insights, helping to identify and rectify biases before they cause harm. A diverse and representative field fosters unbiased practices.
  5. Acknowledge Human Bias: Recognise that all humans have the potential for bias, whether from a difference in lived experience or confirmation bias during research. Marketers utilising AI can acknowledge their own biases to ensure that AI systems remain unbiased.
  6. Transparency: Foster transparency in AI-driven marketing initiatives. Building trust with consumers is paramount, and transparency about the use of AI, such as adding a note below AI-generated content, can go a long way in achieving this.


As marketers, the integration of AI into our strategies presents unprecedented opportunities. However, with great power comes great responsibility. Understanding, identifying, and mitigating AI bias are not just ethical imperatives but essential steps for ensuring the long-term success and sustainability of our marketing efforts. By championing fairness, transparency, and diversity in our AI practices, we can not only navigate the challenges posed by bias but also lead the way in building a marketing landscape that is inclusive, innovative, and ethical.
