I just took this screenshot this morning. Here’s the situation: I’d just installed new trackpad drivers on one of my Windows laptops. This laptop’s trackpad is a bit hinky, so I knew I wanted to get into the trackpad’s control panel and make some settings changes.
So I clicked the trackpad’s system tray icon to open up the control panel. And was presented with this screen.
Of course my first question was “What does clicking Yes do?” Look at that screen for a moment and put yourself in my shoes. I’ve just fired up software I’ve never seen before, I haven’t selected anything from the icon navigation at left, but it’s offering me an enabled Yes button.
I’ve been conducting usability tests for almost 14 years. During that time I’ve noticed that people are usually afraid to press a button or perform an action when they’re uncertain what will happen. I took to calling this phenomenon being “click shy.”
This is a great example of what causes a user to be click shy. It’s a shame, really. Sloppy programming – that is, failing to set the button’s state to disabled when no relevant selection is made – can have a raft of unintended consequences.
