Designing for speed and hacking users perception
summary
Argues that perception beats raw load time: Financial Times sees engagement rise when pages are one second faster, 30% of users still call four‑second loads “slow,” and interfaces feel instant at ~200 ms while attention is lost by eight seconds. Recommends removing the ~300 ms mobile tap delay, adding responsive touch feedback (ripples), using skeleton screens and staggered content to show important bits first, animating progress to accelerate perception, and surfacing core actions (bottom nav vs hamburger) — Google+ and other product tests show these changes increase engagement.
