Separating the two helps a team decide what the account should change. Article on Research strategy, 4 min read Reviewed by [Anne Lacey, Founding Partner](https://antedote.com/why-antedote/#partners) on October 28, 2026. Published October 28, 2026. Consider a hypothetical company that makes smart thermostats. In one interview, a nurse on rotating shifts shows how she enters her shift schedule into the thermostat’s app every Sunday night, because its heating schedule repeats week by week and hers doesn’t. The clip is played at the next three product meetings, and soon everyone is talking about “the nurse problem.” One customer’s story is good evidence of what can happen and how, and poor evidence of how often it does. Treating the account as everyone’s experience and dismissing it as one person’s both skip the more useful question: what has it established, and what decision is it being asked to support? ## Why one account can outweigh a table A story has a person in it. It is easier to remember than a percentage, and easier to retell to a colleague who missed the meeting. Psychologists have long documented that pull. In a [classic experiment](https://doi.org/10.1111/j.1559-1816.1977.tb00750.x), students choosing courses were given average ratings from students who had taken them, and those ratings “had little impact on course choices.” Brief, face-to-face comments about the courses “had a substantial impact.” Course choices are far from a product roadmap, and the pattern is familiar all the same. The clip gets replayed and the survey table doesn’t. Over time, one account can come to stand for the market without anyone deciding that it should. The opposite reflex is no better. “It’s only one person” sounds rigorous, and it can throw away the most useful thing an interview produces. ## Three things a story might show Evidence can show that something is possible, explain how it happens or estimate how often. A single account can do the first two well. It cannot do the third. The nurse’s account shows that the thermostat’s schedule can fail someone whose week doesn’t repeat. It also shows what the workaround costs her: an evening chore each week, and a schedule that is wrong whenever her shifts change at short notice. Someone less patient might switch the schedule off, and lose the feature meant to save energy. In this sense one account can be decisive. Writing in [Qualitative Inquiry](https://doi.org/10.1177/1077800405284363) about what a single case can establish, Bent Flyvbjerg described falsification this way: “if just one observation does not fit with the proposition it is considered not valid generally.” The product’s unspoken assumption, that a household’s week repeats, does not survive her schedule. What the account cannot show is how many customers live like her. People on rotating shifts may be a large share of the company’s customers or a handful, and the vividness of the clip says nothing about which. ## What makes it worth acting on Frequency is one consideration among several, and often not the deciding one. Severity matters. A customer who loses a product’s main benefit is in a different position from one who finds a menu awkward. If the company’s promise rests on the schedule saving energy, a failure there matters even when it is uncommon. So does who is affected. Nurses, factory workers and emergency staff may be a small part of today’s customers and a larger part of the households the company hopes to reach. A problem confined to an audience the strategy ignores is a different matter. The response matters too. If a schedule that repeats on any cycle is a modest software change, a severe problem for a few customers may be worth fixing on the strength of one account and a little confirmation. If it means rebuilding the scheduling system, the team needs a firmer sense of how many people it would serve. ## Evidence that could change the recommendation Other evidence can move the recommendation in either direction, and it needn’t arrive in a fixed order. A few more conversations with people on rotating shifts, or time spent watching how they use the app, would show whether her workaround is typical among them or particular to her. The company’s own usage data might show how often schedules are switched off after the first weeks. A survey could estimate how many customers and prospects work irregular patterns. Each answers a different part of the question. The interview explains a mechanism, and the data says where it applies and how widely. Once the question becomes whether a measured gap is [big enough to act on](https://antedote.com/thinking/when-a-research-difference-matters/), a different judgment begins. Sometimes the extra evidence would change nothing. If the fix is cheap and the failure severe, counting the affected customers first may only delay a sensible change. ## Giving the story its proper weight A report that serves the decision says what the account establishes, what it can’t, and what would change the recommendation. That is the interpretive work of [qualitative research](https://antedote.com/what-we-do/qualitative-research/): connecting one person’s experience to the choice in front of the business, without inflating it or explaining it away. The story everyone remembers can be the most valuable thing a project produces, because it can show a team an assumption it didn’t know it was making. Its weight in the meeting should depend on what it shows and on the decision it is asked to support. ## Read next - *Article* · 4 min read ### [When is a research difference big enough to act on?](https://antedote.com/thinking/when-a-research-difference-matters/) A higher score is a starting point. - *Article* · 3 min read ### [The innovation brief that starts with pleasure](https://antedote.com/thinking/innovation-brief-pleasure/) Enjoyment, anticipation and self-expression can shape an innovation brief from the start.
