Cognitive Load and Willpower

Kathy Sierra is back. Her article Your App Makes Me Fat is an interesting look at the science, and applying it to what we’re asking our users to cope with:

‘If your UX asks the user to make choices, for example, even if those choices are both clear and useful, the act of deciding is a cognitive drain. And not just while they’re deciding… even after we choose, an unconscious cognitive background thread is slowly consuming/leaking resources, “Was that the right choice?”’

Do our UIs deplete a user’s resources?
