Introduction: What is qualitative research

Qualitative research is a non numerical approach to understanding human behaviour, attitudes, motivations, and experiences. Rather than measuring “how much” or “how many,” it seeks to uncover the deeper “why” and “how” behind perceptions, decisions and actions. It is typically exploratory in nature and uses smaller, more focused samples to generate rich, contextual insights.

In contrast, quantitative research relies on structured data from surveys, analytics and experiments to produce statistically robust findings that can be generalised across populations. While quantitative research provides scale and measurement, qualitative research provides depth, nuance, and meaning.

Together, they are complementary. Qualitative research often helps frame hypotheses and interpret results, while quantitative research validates and sizes those insights. The decision on which to use first in a research project often depends on what is currently known about the subject matter and the goal of each stage of research. When there are a lot of unknowns use qualitative research first as a scoping stage to help inform the design of the quantitative stage. When more is known it may be more beneficial to use qualitative research after the quantitative stage to deepdive into specific subject areas or to bring audiences to life.

The decision on which methodology to use will also be guided by your objectives, but may also be a function of budget and the amount of time available to complete your study. In this article we will explore a number of different qualitative methodologies, outlining the pros and cons of each, and when it is appropriate to use them.

Focus Groups: group discussion sessions

Approach:

Focus groups involve moderated discussions with small groups (typically 6–8 participants). Participants are guided through topics or stimuli (e.g. concepts, advertising, products) to explore perceptions, attitudes, and group dynamics.

Groups can be held face-to-face, typically hosted in specialist venues called viewing facilities that allow clients to observe from behind a one way mirror, or online using specialist platforms or standard online meeting platforms such as Teams or Zoom

When to use it:

Focus groups are an appropriate methodology for:

Exploring broad perceptions or attitudes toward a topic
Testing early stage ideas, concepts, or messaging
Understanding social norms, peer influence, or shared language
Generating initial hypotheses or creative directions

Benefits:

✅ Encourages interaction and builds on shared ideas

✅ Efficient way to gather multiple perspectives quickly

✅ Useful for observing group dynamics and consensus formation

✅ Can stimulate ideas participants may not generate individually

Limitations:

❌ Risk of dominant participants influencing the discussion

❌ Social desirability bias may affect responses

❌ Less suitable for sensitive or deeply personal topics

❌ Findings are not generalisable

In depth interviews: one on one sessions

Approach:

One-on-one, unstructured or semi structured interviews that allow for deep exploration of an individual’s experiences, beliefs, and decision-making processes. Interviews are typically guided by a flexible discussion guide.

Interviews can be held face-to-face, either in specialist viewing facilities, in the home of the participant or in another place that has meaning for them in the context of the study e.g. at their place of work or in the environment where they shop. By placing the interview in situ it can help support the interview process by making the participant either more relaxed or by contextualising the subject matter being researched. Interviews can also be carried out online using specialist research platforms e.g. in the case of UX research, or more standard platforms like Teams and Zoom.

Your choice of where to interview the participant and on what platform will be guided by the objectives of the study and the practicalities of running the research project. Whilst it might be optimal to interview a business leader at their place of work, this may not be practical or feasible for either the researcher or the participant so an online approach may end up being the best solution.

When to use it:

IDIs are an appropriate methodology for:

Exploring complex, personal, or sensitive topics
Understanding decision journeys (e.g. healthcare, financial choices)
Interviewing experts, stakeholders, or niche audiences
When individual context and depth are critical

Benefits:

✅ Rich, detailed insight at the individual level
✅ Greater confidentiality encourages openness
✅ Allows for probing and tailored follow-up questions
✅ Minimises peer influence bias

Limitations:

❌ Time-intensive and relatively costly per respondent
❌ Smaller sample sizes limit breadth
❌ Quality heavily depends on interviewer skill
❌ Harder to observe social dynamics

Semiotics: signs & symbols that convey cultural meaning

Semiotics is the study of signs, symbols, and cultural codes. It analyses how meaning is created and communicated through imagery, language, and cultural references

Semiotics unlocks cultural and psychological meanings in consumer behaviour. In commercial contexts, it decodes how brands, products, and communications can be perceived through the signs and symbols they use. This allows businesses to align strategies with cultural trends and consumer values.

Semiotic analysis can be conducted either via desk research or fieldwork. The main approaches are:

Desk Analysis of Stimulus: Evaluate consumer responses, product, packaging or communication for cultural meaning.
Desk Analysis of Cultural Trends: Culture includes beliefs, practices, rituals, norms, institutions, arts amongst others. Culture can be recessive, dominant, emergent and dormant and understanding these trends helps a brand stay relevant. This can be found in category and/or adjacent category products and communications, or cultural expressions in media (films, TV shows, magazines).
Cultural fundamentals: Identify enduring cultural myths—such as the American work ethic or Asian collectivism—and uncover emerging cultural codes relevant to brands. This often involves leveraging deep cultural expertise and local insights.

When to use it:

Understanding brand positioning and category conventions
Analysing visual and cultural communication
Identifying emerging trends and shifts in meaning
Informing creative strategy and messaging

Benefits:

✅ Reveals deep cultural insights and hidden meanings
✅ Identifies category codes (e.g. what signals “premium” or “trust”)
✅ Helps brands differentiate within crowded markets
✅ Provides strategic input beyond stated consumer opinions

Limitations:

❌ Requires specialist expertise
❌ Can be interpretive and subjective
❌ Not based on direct consumer feedback
❌ May need validation through primary research

Ethnography: observation and immersion

Ethnography involves immersing researchers in the participant’s natural environment (e.g. home, workplace, store) to observe behaviours, routines, and contexts in real life. This can be conducted in-person, via digital diaries or through specialy designed digital ethnography apps and platforms

In-person ethnography involves visiting participants in their homes or workplaces to explore routines, environments, and product usage. Observational approaches focus on watching behaviour in natural settings (e.g. retail or healthcare) to identify unmet needs and friction points. Digital ethnography uses tools such as video diaries, mobile apps, or online communities to capture behaviours remotely over time.

Choice of approach or platform will be guided by the objectives of the study and the practicalities of running the project. In person approaches typically take longer and are more expensive to run, but can yield richer insights as they offer the researcher the opportunity to observe participant behaviors first hand. Digital approaches are faster and more scalable, supporting larger numbers of participants, greater geographical dispersion and increased efficiency.

When to Use It:

Building a deep understanding of audiences, their behaviours and motivations
Exploring usage of products or services in context
Understanding real-world behaviours vs. stated behaviours
Identifying unmet needs or pain points
Designing user centric products or experiences

Benefits:

✅ Provides highly contextual, real-life insights
✅ Captures unconscious behaviours and habits
✅ Uncovers gaps between what people say and do
✅ Strong foundation for innovation and design

Limitations:

❌ Time intensive and resource heavy
❌ Smaller samples reduce scalability
❌ Observer presence may influence behaviour
❌ Requires careful interpretation and analysis

Conclusion

Qualitative methodologies are essential tools for uncovering the rich, human stories behind data. Each approach offers a different lens, whether it’s the collective perspective of focus groups, the depth of interviews, the cultural decoding of semiotics, or the real world understanding gained through ethnography and observation.

In practice, the most effective research programmes often combine multiple methods leveraging their complementary strengths to build a holistic, insight driven understanding of audiences.
