DAY 1

1

New article on The Unoptimised Human. Dentsu published strong research on consumer behaviour in 2026. Value-switching, community discovery, transparency demands, optimism under pressure. All real. All important. All attributed to “Gen Z.” But dentsu’s own closing paragraph admits these behaviours “rarely stay contained to one generation.” If they’re not generational, why is the entire article framed around a generation? The data is real. The label is wrong.

2

Dentsu found 48% of Gen Z are more likely to switch brands after the Budget. Generational reading: “young people are less loyal.” Mindset reading: that’s an Adventurer. Adventurers of any age switch when the value equation shifts. The reason it shows up in younger consumers isn’t age. It’s less accumulated brand inertia. The psychology is the same at 25 and 55. The constraint is circumstantial.

3

61% of Gen Z say social media is better than traditional retail for discovering products. Dentsu calls this a generational shift. But my mum gets product recommendations from her WhatsApp group. My neighbour asks Facebook which plumber to use. Community-led discovery isn’t new. The channel changed. The psychology didn’t. That’s a Socialiser, not a generation.

4

A Socialiser at 20 discovers through TikTok creators. A Socialiser at 50 discovers through Facebook groups. A Socialiser at 70 discovers through the church coffee morning. Same drive (relatedness, peer validation, social proof). Different channel. If your strategy optimises for the channel instead of the psychology, it breaks the moment the platform changes.

5

Dentsu reports Gen Z are “more sceptical” and demand transparency from brands. They quote a creator saying “what makes me fall in love with a brand is transparency.” That’s not a Gen Z trait. That’s a Thinker. Thinkers of any age audit before trust. They read the specs. They check the ingredients. They watch the unboxing video. The format of verification changes. The drive is identical.

6

32% of Gen Z say explainer-style content directly influences their purchase decision. Dentsu presents this as a generational insight. But explainer content works for every Thinker, regardless of age. Thinkers want to understand before they commit. They’re watching the review on their phone at 25 and on their desktop at 55. Same content. Same motivation. Different birth year.

7

35% of Gen Z feel more confident about spending despite financial pressure. Dentsu calls this a “distinctive economic mindset.” It’s distinctive, but not generational. It’s the Adventurer mindset: promotion-focused, oriented toward growth and opportunity. Under stress, Adventurers lean forward. A 45-year-old Adventurer with disposable income shows exactly the same pattern.

8

Why does Adventurer-optimism cluster in younger consumers? Not because Adventurers are young. Because young Adventurers have fewer financial anchors. No mortgage to protect. No pension to preserve. Less switching cost. More room to experiment. The optimism isn’t naive. It’s structural. And it exists at every age.

DAY 2

Regulatory Focus Theory, one of STAR’s seven pillars, explains the value-switching data perfectly. Promotion-focused people (Adventurers) seek gains and switch when a better option appears. Prevention-focused people (Realists) avoid losses and stay with the known. This split exists in every generation. Dentsu’s data captures the split. The generational label obscures it.

10

Cognitive Bias Theory explains why the marketing industry keeps using generational frames. Once we believe “Gen Z values X,” confirmation bias kicks in. We notice every data point that confirms it and ignore everything that contradicts it. Dentsu’s own data contradicts their frame. But the frame holds because “Gen Z strategy” sells. Commercial convenience beats accuracy.

11

Dentsu’s recommendations are sound: clear pricing, community presence, useful content, transparent partnerships. Here’s the thing. None of them require a “Gen Z” label. Clear pricing works for every Realist. Community presence works for every Socialiser. Useful content works for every Thinker. Authentic partnerships work for every Adventurer. You don’t need a generational strategy. You need a mindset strategy.

12

“Build a Gen Z discovery strategy around social media” is optimising for the channel, not the psychology. TikTok will change. Algorithms will shift. The drive that makes Socialisers discover through peers is permanent. Build for the drive. The channel is just where it happens to live right now.

13

Self-Determination Theory identifies four fundamental needs: relatedness, competence, autonomy, and security. These are the same four drives that power STAR’s Socialiser, Thinker, Adventurer, and Realist. They exist in a 19-year-old and a 59-year-old. Dentsu’s research describes what happens when these drives meet 2026 market conditions. The drives are human. The conditions are temporal. Conflating the two is the error.

14

Social Identity Theory tells us people form identity around chosen groups, not assigned labels. When you call someone “Gen Z,” you’re giving them a demographic identity that explains nothing about how they think. A Socialiser identifies with their community. A Thinker identifies with their expertise. An Adventurer identifies with their mission. A Realist identifies with their institution. These are real identities. “Born between 1997 and 2012” is a filing system.

15

The most honest paragraph in dentsu’s article is the last one: “Gen Z behaviours rarely stay contained to one generation… behaviour is harder to predict through age alone.” If your own data tells you age is a poor predictor, the frame should change. The fact that it doesn’t tells you something about the incentives of the marketing industry, not the quality of the research.

16

Imagine the brief. “We need to reach people who discover through community, switch when value shifts, demand transparency, and stay optimistic under pressure.” That’s not a generational audience. That’s a combination of mindsets. And it’s significantly larger than Gen Z. Build for that instead.

DAY 3

17

Dentsu calls Gen Z “a leading indicator for the wider market.” They’re right, but not for the reason they think. The indicator isn’t “what young people do.” It’s “what people do when the old structures (brand loyalty, broadcast discovery, institutional trust) fall away.” Remove the scaffolding from anyone, at any age, and the same human operating system emerges.

18

Dual Process Theory, another of STAR’s seven pillars, distinguishes fast intuitive thinking (System 1) from slow analytical thinking (System 2). When a Socialiser sees a TikTok recommendation and clicks buy, that’s System 1 driven by social proof. When a Thinker reads three comparison articles before choosing, that’s System 2 driven by competence. Both systems operate in every generation. The balance varies by mindset, not by birth year.

19

Every generational marketing article has the same structure: here’s what Gen Z does, here’s why it’s different, here’s what brands should do. The first part (the data) is usually solid. The second part (the attribution to generation) is usually unsupported. The third part (the recommendations) would work better if aimed at mindsets instead. The middle section is the problem. Remove it and the strategy improves.

20

Appraisal Theory of Emotion explains why “optimism under pressure” isn’t generational. People don’t respond to financial strain. They respond to what financial strain means to them. To a Realist, it means “cut costs, build savings, stay safe.” To an Adventurer, it means “find new opportunities, experiment, stay free.” Same pressure. Two completely different appraisals. Both exist in every generation.

21

The Big Five personality model shows that traits like Openness, Conscientiousness, and Agreeableness are distributed across the entire population. They don’t cluster by birth year. A highly open 22-year-old and a highly open 52-year-old will both try new brands, both value novelty, both switch when something better appears. Demographics sees the age gap. Psychographics sees the shared trait.

22

If you’re a brand spending six figures on a “Gen Z strategy,” ask yourself: are you reaching everyone who thinks this way, or only the ones born after 1997? Because the 47-year-old Adventurer who’d switch to your product tomorrow isn’t in your targeting. And the 21-year-old Realist who won’t switch regardless is. Demographic targeting misses both. Mindset targeting catches both.

23

Dentsu’s research is worth reading. The data on switching behaviour, discovery patterns, and transparency expectations is genuinely valuable. But read it as a map of how humans behave in 2026 market conditions, not as a map of how young people behave. The conditions (economic pressure, platform shifts, trust erosion) are shared. The people responding to them are psychologically diverse. The mindsets, not the birth years, are what matter.

24

Gen Z didn’t invent community-led discovery. Or value-switching. Or transparency demands. Or optimism under pressure. They’re the first generation to express these behaviours without the scaffolding that suppressed them in previous generations (institutional loyalty, limited information, broadcast-only media). When you remove the scaffolding, the human operating system is what’s left. That’s what STAR maps. And it doesn’t have a birth year.
