Question 1

How can we still run effective mobile qual studies with small budgets?

Accepted Answer

Effective mobile qualitative studies are possible even on small budgets by leveraging participants' own smartphones and zeroing in on high-value activities. For example, instead of costly in-person visits, you can ask respondents to use their phones to capture experiences--such as sending short video or photo diaries from their daily routines. Many low-cost research platforms offer mobile diary or chat tools that let a single moderator manage a study remotely with dozens of participants. To maximize insights per dollar, keep tasks concise (reducing participant burden and incentive costs) and recruit a focused sample so you don't overspend on excessive participants. By embracing everyday tech and streamlining the research design, you can gather rich qualitative insights with minimal expense--just a bit of extra creativity and planning upfront.

Question 2

How should we capture total cost, not price, in choice tasks?

Accepted Answer

In choice-based exercises, present the total cost of each option--not just the sticker price--to ensure respondents weigh realistic trade-offs. This means incorporating all relevant expenses into the choice scenario, such as maintenance, subscription fees, or usage costs over time, rather than a single upfront price. For example, if comparing service plans, you might display the full annual cost of each plan (monthly fee times twelve, plus any extras) so participants consider what they'll actually spend. Emphasizing cumulative cost avoids a common pitfall: options that look cheap initially but end up more expensive in the long run. By capturing total cost of ownership in the task design, you get more accurate insights into true price sensitivity and value perceptions.

Question 3

How can we get topic models to recognize minority or emergent themes?

Accepted Answer

To get topic models to recognize minority or emergent themes, adjust your modeling approach to amplify those rare signals and incorporate some guidance. Standard topic models like LDA can overlook infrequent themes because the most common topics dominate, so one solution is to tweak parameters (for instance, using a higher number of topics or adjusting the priors) to give smaller clusters a chance to surface. You can also seed the model with keywords related to the minority theme or use a semi-supervised approach, where you provide a few examples of the emergent topic to guide the algorithm. Another tactic is to run an initial topic analysis to capture the obvious themes, then remove or downweight those dominant topics and re-run the model on the residual data to reveal subtler ones. Iterative human-in-the-loop modeling — where an analyst reviews interim results and nudges the model (by adjusting settings or adding domain knowledge) — is often effective to ensure niche but important themes are detected by the topic model.

Question 4

When is face-to-face interviewing most effective?

Accepted Answer

Face-to-face interviewing is most effective when research requires deep personal engagement, trust-building, or direct observation that other modes cannot easily provide. In-person interviews excel for sensitive topics where a trusted rapport helps participants open up, and they allow researchers to pick up on non-verbal cues like body language or facial expressions that enrich the data. This method is ideal when the environment or context is important — for example, conducting interviews in a shopper's home or at a store can reveal unspoken behaviors and reactions that might be missed remotely. Face-to-face is also valuable for reaching audiences with limited internet access or for complex tasks that benefit from on-site guidance. While in-person fieldwork can be more costly and time-intensive, it often yields richer insights and more nuanced understanding when these conditions make it the best fit.

Question 5

What challenges arise when scaling adaptive survey platforms globally?

Accepted Answer

Scaling an adaptive survey platform globally brings challenges in language, culture, and data infrastructure - a dynamic survey logic that works in one country may falter when questions are translated or when facing different cultural norms and privacy laws elsewhere. For example, an algorithm that adjusts questions on the fly might struggle with local nuances: a question tree or NLP model trained on responses in English could misinterpret answers in Japanese or Spanish, so careful localization and re-training is needed for each language and culture. Adaptive surveys also rely on machine learning and historical data, which means you need sufficient local data to train the models and must comply with varied data regulations (like GDPR in Europe) governing respondent information; you also have to ensure the platform performs well across different devices and internet speeds in each region. In short, successfully scaling requires tailoring the adaptive logic and content to each locale and shoring up infrastructure and compliance to provide a smooth, trustworthy experience worldwide.
