概要
Apply cognitive science principles (Miller's Law, progressive disclosure, chunking) to UX design, reducing decision fatigue and improving task completion rates.
Cognitive Load Reductionとは
Cognitive load reduction is the application of cognitive science principles to interface design, minimizing mental effort users need to complete tasks. High cognitive load = frustration, abandonment, error. Techniques include chunking information, progressive disclosure, eliminating jargon, and simplifying decisions. Core principles:

❓ よくある質問
What's cognitive load?
Mental effort required to understand and interact with interface. High load = users abandon. Reduce load → higher completion rates, conversion, retention.
How do I measure it?
User testing + task completion time. Shorter time = lower load (usually). Eye-tracking shows where users struggle. Qualitative feedback: 'This is confusing'.
Design system connection?
Design systems = consistent patterns. Consistency reduces cognitive load (users learn once, apply everywhere). System + load-reduction = synergistic.
Job market?
~2k roles (US). UX designers, product managers, interaction designers. Growing trend toward 'cognitive UX specialist'.
Can I apply this to forms?
Yes. Multi-step form (cognitive break) easier than 20-field form (cognitive overload). Progressive disclosure, placeholders, clear labels reduce load.
ROI of optimization?
Form reduction (10→5 fields) = 20–30% higher completion. Decision simplification = 15% conversion improvement. Measurable.
Salary impact?
UX designer $80–140k + cognitive load expertise = $110–180k. Product manager $120–200k + this = $150–260k.
