People develop their identity continuously. Intuitively, we assume that identity is static—that who we are remains constant. However, research shows that identity is fluid and develops in stages. Brands that ignore this development lose customers at critical transitions. The question is: How do people progress through identity formation stages, what needs do they have at each stage—and what evidence supports this?
Studies
# Identity Status Interview
James Marcia developed a groundbreaking interview procedure for measuring identity development at the University of British Columbia in 1966. He extensively interviewed 86 male college students about their beliefs in areas such as occupation, religion, and politics. Based on two dimensions—exploration (whether they had considered alternatives) and commitment (whether they had made firm decisions)—he identified four distinct identity statuses: Diffusion (no exploration, no commitment), Moratorium (active exploration, no commitment), Foreclosure (commitment without exploration), and Achievement (commitment after exploration). The striking finding: students in different statuses exhibited measurably different behaviors—Achievement status correlated with higher stress resilience and more mature coping strategies, while Diffusion was associated with disorientation and low self-efficacy.
Longitudinal Identity Development Study
Jane Kroger conducted one of the most comprehensive longitudinal studies on identity development at Victoria University of Wellington between 1983 and 2007. She followed 113 New Zealanders over 24 years—from adolescence to middle adulthood—interviewing them every four years using Marcia's Identity Status Interview. The results challenged the assumption of linear development: only 36% moved continuously forward to Achievement, 25% showed regression, 21% remained stable in one status, and 18% oscillated between statuses. The surprising finding: identity development is not a one-way street. Even at age 36, only 40% had reached Achievement status. Life transitions such as divorce or job loss often triggered renewed exploration phases—people can switch between statuses multiple times.
Principle
Which principle for Customer Experience Design can be derived from this? The central principle is: Accompany identity development rather than assuming static personas. Successful customer experience emerges when brands avoid categorizing customers into fixed segments and instead understand them as evolving individuals, actively supporting their growth phases. This approach proves particularly effective in long-term customer relationships and life domains with high personal relevance, such as career, family, or health. However, this strategy requires continuous observation and adaptation of offerings, making it less practical for short-term transactions or standardized products. The following guidelines demonstrate how to implement this principle in practice.
Guidelines
Segment onboarding by development phase
Identify which identity phase new customers are in and tailor the onboarding accordingly. Explorers need orientation and opportunities to experiment. People in the commitment phase need confirmation and deeper engagement. During onboarding, don't just collect demographic data—ask about goals, uncertainties, and previous experiences. For example, a fintech company could ask: "Where are you right now? (a) I'm exploring different investment strategies (b) I've found my strategy and want to implement it (c) I'm optimizing my established strategy." The answer determines the subsequent onboarding flow.
Proactively support transitions between phases
Identify signals indicating phase transitions and proactively offer support. When an explorer shows signs of commitment—such as repeated interest in specific features or more consistent usage patterns—provide resources for the next phase: in-depth masterclasses, peer groups with experienced users, and tools for optimization rather than exploration. For example, a fitness app could prompt after three months of consistent usage: "You seem to have found your rhythm. Ready for the next step? Let's define your long-term goals together." The transition becomes a shared milestone rather than a breaking point.
Making development progress visible
Make personal development journeys visible and celebrate milestones reached. Showcase not merely product usage, but identity evolution. A language learning tool might visualize: 'You've evolved from curiosity (explored 100 words) through commitment (15 minutes daily for 3 months) to competence (completed your first conversation).' This meta-reflection deepens attachment by positioning the brand as a witness to personal transformation. Critical point: The phases must be individually distinctive, not generic progress bars.
Frame setbacks as development
Recognize that identity development is nonlinear and frame setbacks as a natural part of the process. When established users return to exploration (following a crisis or major change), create space for this rather than pushing them forward. For example, a career platform could respond to prolonged inactivity not with admonishment but with an invitation: "Are you reconsidering your path? Many successful people have adjusted their direction multiple times. How can we support you during this phase?" The underlying message: revision is a sign of maturity, not failure. This approach creates psychological safety that enables lifelong engagement.
