Once again, I recently found myself in a consulting meeting, needing to explain the difference between check boxes and radio buttons. Those that follow my blog might ask, “Ben, why do you gripe about this so much?” So let me clarify why it’s important to think through this issue.
My issue is NOT about
1. expecting others to be able to describe computer technology correctly. (After all, the functionality of check boxes and radio buttons is retroactively obvious. Once you see the function of both explained side by side, it’s readily apparent what the differences are and why.) It has never been my desire to turn the general population into computer engineers, developers, or designers.
It’s only partially about
2. others being able to design appropriately — describing the appropriate interface element for the application — though this is crucially important. I have increasingly seen check boxes and radio buttons used interchangeably and the functionality behind them intentionally coded incorrectly, resulting in a radio button interface behaving like a set of check boxes and check boxes being leveraged like radio buttons. In fact, just a handful of weeks ago I was auditing some on-line training from a standard provider for that particular industry. All the exams were multiple-choice questions. The questions did not indicate if one response or multiple responses were required. Check boxes were used, yet most often, only one response was correct. But not always. Perhaps this was an intentional design choice. But having also just consulted with individuals designing a new website (who clearly did not know the difference and selected the wrong interface element), I can’t guarantee the choice was an informed one. In this case, had I not thought through the interface, applied my technology background, and then assessed the questions again, I might have failed the exam.
