I write a bunch of form labels on the whiteboard, in a nonsensical order, along with a bunch of randomly sized input boxes. I include first name, last name, address, gender, city, state, email address, etc. Then I tell the interviewee that we’re designing a form to sign up for an email newsletter and to arrange them in the right order. Only people who ask me why I need the users’ gender, or physical address, or really, anything but their email address get a second interview.
