About two weeks ago I was looking around the blog for IxDA Waterloo – a local group which holds monthly meetings to talk about various topics in user experience/interaction design – and I discovered something. I have developed a new mental model for red links.

It happened when I was looking at an older post on the site, one with links I had already visited, but forgot that I had seen. For whatever reason, the theme used at the blog styles visited links a red colour. Not really a big deal right? Red’s a nice enough colour.

When I considered hitting the link, I noticed it was red. Immediately I changed my mind and kept browsing. Moments later, I found another red link, and was a little irritated. It took me a few seconds to realize why, but thanks to Wikipedia‘s styling, I have apparently started associating red links with missing content.

For those readers who aren’t familiar with Wikipedia, it hosts a bunch of information on basically everything. Each page on the site is full of links to other pages within the site, but sometimes those pages get removed, or links to pages that don’t exist are added to remind someone to make that page later. To help out their users, Wikipedia has styled these links in a red colour, so that readers know that there’s no page at the other end of that link.

Realizing this, I went ahead and clicked the links to find that I’d already seen the content. So what does this mean? For starters, the blog’s operators should probably fix this problem, being as it is a blog for a user experience group and shouldn’t go around messing with people’s mental models. It also means that the next time I design a web-based system I’ll have a new mental model in mind to optimize how my users will interact with it.

I’d like to point out that IxDA Waterloo is an awesome group. If you’re in the Waterloo region and interested in user experience or interaction design, I’d highly recommend joining the User Experience Peer Group at Communitech’s website, joining the local IxDA group, and coming out to their monthly meetings. March’s meeting was on table-top computing, and in April we did a UX Show and Tell where I recently gave a short presentation on Project MORIS. Its definitely worth your time.

Has anyone else noticed they’ve started to treat red links in the same manner? Questions/remarks about mental models or something else I mentioned in this post? Let me know in the comments.
