5 Psychology-Backed Principles for More Effective Personalization

Personalization has become a baseline expectation across industries. Deloitte has found that nearly three quarters of consumers are more likely to buy from brands that personalize, and McKinsey has shown that companies that excel at personalization generate up to 40% more revenue than their peers. The economic upside is clear, and AI is quickly scaling these capabilities. In this landscape, a new category I call “confessional commerce” is emerging: products deliberately designed to rely on users’ disclosure of deeply personal, contextual information to create value. Examples include health apps that surface embarrassing symptoms, learning platforms that invite users to admit skills gaps, and beauty tools that expose appearance insecurities. In each case, products improve as users open up and share more information. Core to confessional commerce is a simple value exchange: The more candid a customer is in the moment, the more a product can be personalized to meet their needs. A fitness app is useless unless it understands how you spend your time. A financial plan is only successful if it accounts for real spending habits. A mental health app can’t help unless it knows your struggles. Gen AI tools excel at eliciting this kind of disclosure, routinely drawing out deeper unfiltered accounts by reducing the psychological barriers that suppress honesty. Millions confess to an algorithm what they will not tell a human. They might up a conversation with ChatGPT, for example, by saying, “I’m 34 and don’t know what a Roth IRA is,” whereas in the same situation with a human advisor they might only say, “I’m interested in retirement planning.” Greater honesty enables more precise responses, which builds trust and creates value. Despite the upside, most teams still design for speed over depth. Early product interactions are often shortened and streamlined, because teams assume increasingly sophisticated models can infer what matters for customization from past behavior. When the model is expected to do this work, probing for further understanding feels unnecessary. Confessional commerce takes a different approach. It combines what systems can predict with what people will share in the moment—what they’re worried about, excited by, or trying to solve right now. This mirrors how professional therapists work: They let patterns and history inform their expectations, but what drives their work is what people reveal in session. Decades of research in clinical psychology have established what reliably draws out deeper disclosure. In my work building and marketing personalization products, I’ve found that five principles drawn from this research are especially relevant for teams engaging in confessional commerce. 1) Lead with “Why now?” Most companies offering personalized products start by asking about goals. It seems efficient: If you know someone’s goals, you can narrow their menu of choices and quickly get them on the right path to success. Unfortunately, goals don’t tell you why your customer is here right now. In cognitive behavioral therapy (CBT), therapists don’t begin their client encounters with talk of goals. Instead, they ask some form of the question “What brings you here today?” This allows them to get at something more important and immediate: the “precipitating event” that caused their clients to seek help. Psychologists have learned that when you engage someone in their immediate lived experience in that way, you can quickly develop trust. Similar dynamics are at play in confessional commerce. Consider the case of a fitness tool. If it asks you for goals, it’s likely to learn something generic (“I want to get in shape”). However, if it asks what prompted you to sign up today, it can elicit your why (“I get out of breath just carrying my daughter”). By first understanding the precipitating event, it can develop a much fuller sense of your goals: the context, the stakes, the urgency, the personal meaning. Personalization moves beyond categorization into attunement. 2) Normalize reactions to reduce shame. Even when people know what brought them to a product, they don’t always want to say it. Diana Fosha’s work in accelerated experiential dynamic psychotherapy (AEDP), shows that difficult emotions are harder to articulate when they’re held alone. Shame, in particular, blocks honesty when people believe their experience is unique or abnormal. Fosha calls the antidote “undoing aloneness”: helping clients feel accompanied rather than left to manage those emotions in isolation. In CBT this same effect is achieved through normalization. When you signal that a reaction is understandable and shared, you can reliably reduce shame and encourage more accurate disclosure. That applies in confessional commerce too. When people are asked for sensitive information without any acknowledgement that how they feel is common, they tend to give safe, surface level answers. Normalizing the reaction, however, lowers the cost of honesty by demonstrating that the product understands the context behind the question. But this isn’t about making users comfortable. It’s about helping them feel safe in being uncomfortable. Without that sense of safety, trust cannot be formed and products may collect data, but they will miss the insight needed for competitive personalization. 3) Invite follow-up. Most companies treat disclosure as a single-step interaction: Ask a question, capture an answer, move on. That works for functional data but not for the kind of information that reveals the problems people are actually trying to solve. In his work, the psychologist James Bugental observed that people rarely arrive at the full truth in their first attempt to describe a challenge to a therapist. Their initial response is usually protective, safe, and vague. It’s only when they feel a sense of being accurately understood, Bugental argued, that they become willing to offer deeper insights into how they think and feel. That’s why therapists often repeat what their clients say: not to echo them but to signal attunement and invite depth. Confessional commerce can make use of these ideas. In informational exchanges, when asked what they want, customers will initially say what they believe is acceptable (“I want to save more money”). But encouraged to go deeper with follow-up questions that focus on the why and normalize their feelings, they will often provide a richer, more expressive articulation (“I’m worried, last month’s bills wiped out my savings”). As Bugental puts it, the first articulation identifies the topic, the second adds emotional texture, and the third often reveals the true need. Designing for this doesn’t require that you ask users to complete long forms or put up with additional friction. It requires designing for iteration rather than extraction. Depth only slows users down if it feels extractive. When customers feel emotionally understood, they stay with you, because what you’re asking feels relevant, and the deeper truths they then reveal can positively impact conversion, completion, and more. 4) Focus on the how, not just the what. Product teams often focus on what customers say. But as the psychiatrist Irvin Yalom has shown, how someone speaks often reveals more than what they say. Yalom trained therapists to focus on “process”: nuances such as tone, hesitation, pacing, and repeated revisions. When a client says “I’m fine” in a flat voice or after a pause, their manner of speaking suggests the opposite: They’re not fine. This focus on the how can also be useful in confessional commerce. A customer fills out an income field, deletes it, re-enters it, deletes it again, then finally submits a number. A system that focuses only on the final number is losing access to valuable information, because in deliberating about what number to use, the customer was probably disclosing fear, uncertainty, or discomfort. A process-aware product can respond to that kind of situation with attunement in the moment that will help generate a feeling of safety and trust (“This question can be tricky for many. An estimate will do.”). Bugental emphasized in his work that therapists can become more sensitive with practice. The key, he argued, is to notice a cue, name it, and learn from how the person responds. In confessional commerce, you can build similar feedback loops by tracking not only what consumers input but how they input it: time spent on a question, revision patterns, sudden brevity, abandonment points. What’s important is to treat what customers say and how they say it as complementary layers of data that together reveal what people aren’t ready or able to articulate. 5) Build value loops. Disclosure is not a one-off moment. It unfolds over time, and with each disclosure people will observe how you respond, all the while asking themselves, consciously or unconsciously, “Is this safe? Did you understand me? Did I gain anything from sharing?” When your responses are attuned and useful to them, people will disclose a little more. But when an insight falls flat, or a message feels canned, or a moment of honesty produces no value, they will retreat. This loop is the psychological engine of confessional commerce: Disclosure drives value, and value drives further disclosure. One grounded response creates the first turn of the flywheel and repetition builds depth through richer data. The key to sustaining this loop is to build it on a system that behaves stable and authentic in presence. Fosha’s work has shown that people open up when the other party is experienced as steady, responsive, and non-judgmental, creating a sense of secure attachment. This is where modern organizations face the greatest risk. An AI assistant might normalize a consumer’s fear, invite deeper articulation, and deliver clear value, allowing trust to develop. But then a support agent, a sales email or a marketing message might provide only generic information or forget context. Suddenly trust disappears, and the value loop is broken. To sustain the loop, teams have to adopt the same psychological stance across every touchpoint: AI assistants, human supports, sales, success and marketing. To do this companies must create disclosure protocols, train customer-facing teams to align with their digital products, and audit handoffs. Trust and value only compound when experiences feel stable, responsive, and consistent across every interaction. . . . These principles rest on a common foundation: genuine care for the people you serve. Not as a value statement but as a design commitment that governs how information is handled, how context is preserved, and how responses are shaped over time. Confessional commerce doesn’t make sense for every product. Low-stakes, transactional categories won’t benefit from deeper disclosure and shouldn’t ask for it. But in domains where context, sensitive information, and lived experience shape outcomes, depth becomes a competitive advantage. And depth is only possible when psychological insight and technological capability are designed to reinforce each other.
