Design to Boost Conversion vs. Design That Puts Users First—Which Is Better?

Why Read This from an HCI Perspective

This article helps you rethink UX not as ‘making pretty screens,’ but as how interfaces support users’ judgments and actions. It’s true that focusing only on conversion can look good, but it can also erode user trust and increase drop-off. For HCI practitioners and researchers, it’s a useful piece that clarifies why it’s necessary to view both business metrics and usability metrics together.

CIT's Commentary

The core message here isn’t that conversion rates are inherently bad—it’s that when conversion becomes the only compass, the interface can shift from being a tool that helps users to a mechanism that pressures them. Patterns like pop-ups, scarcity messages, and hidden costs may generate short-term gains, but trust collapses the moment users feel ‘tricked.’ Especially in systems where safety matters, users must understand what’s happening right now and be able to leave at any time. In this context, measuring ‘how easily users can make the right decisions’ is more sustainable than measuring ‘how many times they clicked.’ And when applying these principles to real products, you have to handle the trade-off honestly: lower conversions and reduced short-term revenue.

• Q.How far should conversion-effective patterns—like scarcity messages or pop-ups—be allowed before they cross into unethical design?
• Q.In Korea’s Naver, Kakao, and startup ecosystems, where would global UX principles need to be applied differently?
