Sub-shift
“WHOSE IDEA WAS THAT?”
Consumer preferences can form inside a helpful conversation.
Someone asks for help thinking through a change in their life. The conversation gradually acquires a direction: a different routine, a new interest, perhaps something to buy. By the end, the recommendation can feel like the natural conclusion of their own reasoning.
Advice has always influenced what people want. Conversational AI can make that influence unusually personal and continuous. It can respond to hesitation, return to an aspiration mentioned earlier and explain why an option seems right for this particular person.
Over the next one to three years, we expect more consumer decisions to take shape this way. “WHOSE IDEA WAS THAT?” examines the point where a system moves from helping someone express a preference to helping form it. That can expand a person's choices. It can also make the commercial purpose behind an exchange harder to recognize.
The conversation has a purpose
In an April 2026 preprint, Francesco Salvi and colleagues studied conversational book selection. Models instructed to promote randomly designated sponsored titles shifted choices more effectively than placement alone; disclosure did not eliminate the effect. The study concerned a single incentivized book selection, not ordinary high-stakes purchases or repeated use. [68]
The mechanism is commercially significant even within those limits. A recommendation can be explained through the person's stated tastes and concerns, rather than simply displayed nearby. The service helps construct the reasons for choosing it.
A different study shows how agreement can shape judgment. Myra Cheng and colleagues found that affirming advice made participants more convinced of their position in a conflict and less willing to repair it, even while they preferred the agreeable AI. Extending that finding to lasting values or buying behaviour would go beyond the evidence. It does suggest that a pleased user is not necessarily a better-informed one. [64]
Help customers examine the reasons
For businesses developing advice-led services, the opportunity is a relationship in which customers can work out what matters to them. That might lead to a purchase, a different choice or a decision to wait. A service that only counts conversion will miss those distinctions.
Make its purpose clear where it matters. If a commercial arrangement shapes the options, the customer should be able to understand how. Give them room to ask for another interpretation or compare a different route. A label alone may not explain the role sponsorship played in an apparently personal recommendation.
Persuasion is not inherently unwelcome. People seek advice because they are willing to reconsider something. The question is whether they can recognize and endorse the reasons for the change. You could learn more by asking customers to explain their decision afterwards, including the alternatives they rejected, than by measuring how agreeable the exchange felt.
An assistant may become influential before a customer has settled on a product category at all. That makes the quality and purpose of the advice part of the offer, not merely a route to selling it.

A digital wardrobe starts trying on beauty, too
Beauty brand e.l.f. Cosmetics and AI styling app Alta
Brand recommendations enter personal styling; influence on preferences is plausible but not measured here.
Why this example is here
This is a commercial styling integration, not evidence that using an avatar changes someone’s identity. The issuer says Alta will recommend e.l.f. products; it is not a neutral comparison across all beauty brands.

Sources and further reading
These sources inform the article. A product announcement describes an offer, not how widely people use it. Arguments and imagined futures are kept separate from observed results.
2,012 active US eBook readers, single-session incentivized choice. Not broad purchasing telemetry; long-term and high-stakes generalization unresolved.
Conflict-related judgments and repair intentions changed after interaction. Does not establish permanent personality change or effects from every assistant.
About this research edition
This article draws on selected sources and our interpretation of their implications for consumers. The wider collection contains 50 articles and original illustrations. We have not read everything by everyone on the reading list, calculated the probability of each future or established worldwide adoption. The collection is not exhaustive.
The illustrations are AI-generated, with a visual approach informed by TrendWatching’s 2024 and 2025 reports. They depict ideas rather than observed events. If an article’s central idea changes, its image needs another look. Small edits need not mean a new illustration; automatic replacement is not active.
Each innovation has a source, a review date and an explanation of its relevance and limits. Some are early signs of the change; others offer a useful comparison. None proves the forecast. Monthly monitoring and automatic selection of new examples are not running.
