Nudging Through Cognitive Design: Scaling Behavioural Science Across Product Architecture
The Challenge
- The Friction: Internal performance data showed that application completion rates were low. A disproportionate number of users abandoned the digital registration funnel usually around page four before completing the form.
- The Root Cause: User testing revealed severe cognitive friction. The legacy interface relied on an intimidating wall of copy that triggered choice overload (too many plan variables) and loss aversion (fear of choosing the wrong coverage), making the registration feel complex and exhausting.
- The Corporate Constraint: Operating within a highly regulated enterprise ecosystem meant every structural iteration had to pass strict legal and compliance audits, leaving zero room for deceptive UX patterns.
- The Goal: Redesign the registration workflow to simplify complex choices, reduce cognitive load, and measurably increase end-to-end conversions.
My Scientific Process & Leadership Role
As the Content & Behavioural Strategy Lead, I didn’t just rewrite copy, I established a strategic upskilling framework to integrate behavioural economics directly into Sun Life’s UX workflow. I mapped the problem space using a strict diagnostic audit and executed two targeted behavioral design strategies:
Solution 1: Copy Minimization & Cognitive Progression
- The Science: The volume of text visually dictates how complex a process feels to a user before they even read it.
- The Execution: I audited the informational hierarchy and aggressively stripped away non-essential copy from the main screen layout. I re-architected the layout to place optional, secondary explanation copy inside interactive tooltips.
- The Design Flow: I restructured the remaining text into a clean cognitive progression:
Solution 2: The Affect Heuristic via Conversational UI
- The Science: Emotion directly guides decision-making. If content feels warm, plain-spoken, and empathetic, the user’s micro-stress level drops, which correlates with an increase in task completion.
- The Execution: I coached writers and visual designers to move away from rigid, transactional form fields. We redesigned the form inputs into an empathetic, conversational dialogue where questions were fully spelled out to feel like a supportive, human-led guide.
Stakeholder Collaboration
- The Architectural Bridge: I worked side-by-side with the Principal Business Architect to ensure these optimized behavioural content frameworks perfectly aligned with the underlying data mapping capabilities of the backend tech stack.
- The Compliance Shield: Acted as the core interface between UX design and the legal team. I successfully defended the behavioural framing mechanics by providing clear empirical evidence that psychological framing improved product transparency and reduced user confusion, satisfying compliance requirements while keeping the UX vision completely intact.
The Measurable Impact
- The Core Metric: The redesigned conversational and minimized copy structure achieved a 12% increase in digital conversions, allowing applicants to confidently navigate the registration process without dropping out.
- Long-Term Enterprise Asset: Beyond the immediate lift, the tools and workshops created during this 2022 initiative provided a foundational playbook for visual designers and writers to scale behavioural metrics across Sun Life’s global direct-to-consumer digital portfolio.
