Click OK to Cancel
Here’s a devious twist on trained behavior. In the normal confirmation dialog, you click Cancel to back out of some action you don’t want to do:
Out of curiosity, I clicked a sales-pitch link from a Google search I normally wouldn’t. When I clicked my browser’s Back button, the following confirmation dialog appeared:
This is devious in several ways:
- I clicked my browser’s Back button. I didn’t click the Oh Please Show Me An Annoying Pop-up button. I just want to see the previous page, nothing else. Now I’m unhappy.
- Cancel/OK buttons are confusing enough on their own. To receive a discount I click Cancel? I thought clicking Cancel would stop what I didn’t want to happen. Will clicking OK infect my laptop with leeches?
- Cancel and OK are in most cases bad names for buttons. Use descriptive verbs, such as “Yes, leave this page” and “No, stay here” (of course, you’d have to fake a confirmation dialog to control the button labels).
- Don’t make the selection I most likely don’t want the default action. And don’t give the buttons equal visual weight.
