Back in law school, I did a lot of reading. We all had to. For my part, I would hunker down like a goblin in the law library and grind through text after text for as long as I could. But, after a while, it would get harder to think and harder to focus, and I would find myself re-reading the same sentence over and over, and then I knew it was time to take a break. I suspect a lot of people can relate to that.
Attention Limits Under Load
As it turns out, research shows that our capacity to apply our attention to a difficult task declines with sustained effort. How long we can go varies from person to person, and we can improve with practice, but we all have our limits.
A useful analogy is to think of attention and effort like carrying a bag of groceries. Some people can carry more, and others less, but for everyone, even a load that started out manageable becomes harder to carry over time. Likewise, when we ask people to apply their attention and effort to legal information for too long, their performance starts to deteriorate. They can miss steps, overlook details, or give up on a task altogether.
So when we design legal information, we should not assume that people apply consistent focus at the same rate over a long period of time. Instead, we should expect them to pause, take breaks, and come back later.
Re-entry Design
Re-entry Design means structuring information so people can pause, lose focus, and return without having to start over mentally. Contrast this with Linear Design, which presumes a person will begin at the start of a process and continue uninterrupted through the end.
There are many ways to design for Re-entry, but the most important principle is to group related information together. Information might be related because it is associated in real life, like grouping property categories in a divorce matter. But it might also be related because a person must rely on that information to complete a later task.
In that same divorce matter, if we explain the difference between community and separate property in the middle of early instructions, but a user needs to apply that concept in their petition ten pages later, that related information is not really grouped together. Because of our Working Memory Limits, we cannot expect users to carry that information forward, especially if they are interrupted. From a Re-entry Design standpoint, we might want to reconsider our organization.
Re-entry Design applies both to concepts and to visual cues that help a person find their place when they step away and come back. Clear section headers and a predictable visual structure also help people find, recognize, and reorient to that information quickly.
Legal Information Rarely Stands Alone
How much we need to focus on Re-entry Design depends on how long we need a person to focus their attention. However, even short documents rarely stand alone. Often, they are part of larger legal processes that unfolds over days, weeks, or months. Something that appears simple enough for Linear Design might really be part of a broader process that also requires some Re-entry thinking.
