DEEP BACKGROUND 05 OF 13 . FANATICS Why do the most committed fans take a brand's decisions personally? Because they are not consuming the thing, they are using it to hold their own self-image together. Students displayed their university's colours more after a win than a loss, and the effect was strongest among those who had just personally failed. WHY THIS IS WORTH MONEY Every organisation with committed fans eventually does something those fans read as betrayal, and is surprised by the size of the reaction. A price change, a format change, a partnership. If the mechanism is preference, the reaction is disproportionate and you manage it as a communications problem. If the mechanism is identity, the reaction is exactly proportionate and communications will not touch it. Getting that wrong is expensive twice over. Once in the reaction, and again in what you conclude from it. WHAT THE RECORD SHOWS The apparel study, and it is the durable one Cialdini and colleagues (Journal of Personality and Social Psychology, 1976) covertly monitored what students wore to Monday classes at seven large universities across a football season, counting school-identifying clothing. Colour alone did not count. Notebooks did not count. The index was scaled against each school's own highest Monday. Mean after wins: .63. Mean after nonwins: .44. Mean rank 3.2 for victories against 4.9 for nonvictories, Wilcoxon T = 2, p < .05. In their words, "students chose to display more apparel indicators of their academic affiliation after their university's varsity football team had recently been successful." The pronoun study, and what happened to it in 2016 The famous number from the same paper comes from a second study. One hundred and seventy three students were telephoned, given false feedback that they had scored five out of six or one out of six on a campus quiz, and then asked to describe one of their team's games. Overall, 32 per cent said "we" about a victory against 18 per cent about a defeat. Among those who had just been told they personally failed, the gap widened to 40 per cent against 14. Among those told they had succeeded it almost vanished, 24 against 22. Read on its own that is the whole argument of this page. Identification with the thing gets stronger when the person's own self-image is under threat. And it did not reproduce. Jensen and colleagues (Journal of Sport Management, 2016) re-ran both studies forty years on. Study 1, the apparel study, reproduced: participants were "more than twice as likely to wear school-affiliated apparel after wins and 55% less likely after losses". Study 2 did not. So the honest position is this. The behaviour is well established. The specific experiment that produced the personal-failure figures failed a replication, and anybody building on 40 against 14 should say so on the same page. We do. What the commercial consequence looks like Kwon, Pyun and Lim (Frontiers in Psychology, 2022) meta-analysed the link between team identification and consumption. Identification to attendance intention across thirteen studies: r = 0.39. Identification to intention to buy licensed merchandise across nine studies: r = 0.42. Both are medium to large. Both are intentions rather than observed spend, and the authors ran a publication bias check, which tells you bias was a live concern in that literature. Take the direction, and treat the size as the top of the range. THE STRONGEST OBJECTION, AND THE ANSWER TO IT Fournier and Avery (Business Horizons, 2011) is the sharpest thing written against brands strategising on fan identity, and it is not the objection people expect. Their argument is not that fan identity is unreal. It is that the brand does not own it. "The Web was created not to sell branded products, but to link people together in collective conversational webs." And: "Brands are uninvited crashers of the Web 2.0 party." Then the sentence that should be pinned above any fan strategy: "Marketers lost control of their content and the reach, frequency, and timing of the distribution of their messages." Their name for the condition is open source branding, "when a brand is embedded in a cultural conversation such that consumers gain an equal, if not greater, say than marketers in what the brand looks like and how it behaves." The trade they identify is exact: "in gaining resonance, the brand relinquishes control." That is not a rebuttal of this page. It is the price of it, and it strengthens the mechanism rather than weakening it. The more the domain matters to a person, the less any brand decision is received as a brand decision. There is a second objection worth naming. Avis, Aitken and Ferguson (Marketing Theory, 2012) argue that brand relationship and brand personality theory rest on two incompatible foundations, one holding that consumers really do perceive brands as humanlike, the other treating the relationship language as a metaphor researchers imported, and that the field has never resolved which it means. We do not need it resolved. Nothing on this page requires a person to relate to a brand as though it were a person. It requires them to use a domain to say something about themselves, which is what Cialdini measured. WHERE THE EVIDENCE STOPS The pronoun figures come from an experiment that failed a forty year replication. Do not build a client argument on them alone. The apparel finding reproduced, and it is about university sport. Transfer to a commercial category is an argument, not a measurement. The identification meta-analysis measures stated intention, not money that moved. We could find no study linking fan identification to observed revenue or churn. None of this establishes how large the Fanatic position is in any domain, and no proportion should ever be quoted as a rule. WHERE THE CONE SITS Fanatics are a position inside one domain, not a personality type and not a heavy user segment. They have followed the logic of the category all the way to its end, and the end is usually somewhere the business cannot go. Which makes them the truest signal you will get and the worst brief you will receive, both at once. They tell you the direction of travel and the moral centre of the category. They do not tell you what to launch. And it explains why selling out is not a marketing disagreement to them. If the thing is part of how somebody holds themselves together, a change to it is done to them. WHAT TO DO ON MONDAY Find six people at the top of your domain and ask them the purest version of your question, the one you are slightly afraid of. Write the answer down exactly as given. Do not soften it, do not brief against it, and do not build it. File it as your direction of travel and check every idea for the next year against it. Next is the position that actually carries you outward, and the published finding that should worry anybody selling influence. SOURCES Cialdini, R. B., Borden, R. J., Thorne, A., Walker, M.
