“It’s very important to consider your content from your user’s perspective. Is it written so that your target audience will understand and relate to it?”

Content Strategy for the Web, p. 56

In Kristina Halvorson’s book, she reminds us to consider our target audience when writing content for them. Who that audience is will, of course, depend on your particular site and its goals. But if your target audience includes the general public, you may want to consider that nearly half of them may have low literacy skills.

That’s right. Half.

Don’t believe me? I don’t blame you, it’s a shocking number. But for proof, just check out the results of the National Adult Literacy Survey. It found that 21-23% of U.S. adults had highly deficient literacy skills while another 25-28% had very limited literacy skills.[1] Those two are the groups it defines as having low literacy. The Organization for Economic Co-Operation and Development found similar levels of low literacy in North America, Australia, and most of Europe.[2]

What is low literacy?

The National Literacy Act of 1991 defines literacy as “the ability to read, write and speak English; compute and solve problems at levels of proficiency necessary to function on the job and in society; to achieve one’s goals; and to develop one’s knowledge and potential.” The basic skills needed for literacy include things like recognizing words fluently, understanding the structure of sentences and how they relate to each other, drawing appropriate inferences, applying information, and solving quantitative problems.

A person with low literacy skills will have a harder time doing things like filling out a job application, interpreting a bus schedule, or understanding when to take medications.

Low literacy does not mean illiteracy. But it used to. As recently as 1979, the U.S. Census Bureau defined as illiterate anyone who hadn’t finished the fifth grade.[3] In the 1800s you only had to be able to sign your name to be considered literate. We now view literacy as something that exists in gradations, not as something you either have or don’t have.

Who are these people?

There are many misconceptions about low literacy, what it means, and whom it affects. While you might assume that only those who didn’t finish high school or speak English as a second language have low literacy skills, you’d be wrong. Although minority groups are disproportionately affected by low literacy, most of those with low literacy skills in the United States are white and native-born.[4] Completing high school doesn’t get you out of the woods either: a person’s literacy skills tend to be three to five grade levels lower than the last school year completed.[5] The elderly tend to have much worse rates of low literacy skills, with nearly 35% of US residents aged 60-65 considered not functionally literate.[6]

Its important to note that low literacy doesn’t indicate a lack of intelligence, but a lack of skills. Reading, writing, and comprehension skills are underdeveloped in people who have low literacy, but that doesn’t mean they can’t be developed.[7] Think of it this way: I may not be the best typist, what with my 20-word-per-minute rate, but just because I’m not good at typing doesn’t necessarily mean there’s anything wrong with me or that I’m dumb—it simply means I haven’t developed that skill.

Think you can tell who has low literacy skills by simply looking at or talking to them? You might not be as successful as you’d expect. Practitioners in the medical profession frequently deal with patients who have low literacy skills. Yet when physicians at one women’s health clinic were asked to identify which of their patients were very low-literacy (defined in this study as reading below a third-grade level) they only did so successfully 20% of time.[8]

It’s so difficult to tell when someone has low literacy skills for two main reasons:

  • They’ve developed coping mechanisms that hide their condition.
  • They don’t think of themselves as being poor readers.

In one study, two-thirds of those who admitted having reading difficulties had never told their spouse; 19% had never told anyone.[9] Because of the stigma associated with poor reading skills, most people won’t. Instead they’ll come up with strategies to avoid reading, like saying they’ve left their glasses at home or that they usually leave the work of filling out forms to a family member.

Most poor readers also view their own reading skills as adequate. In the National Adult Literacy Survey, 66 to 75% of adults in the very lowest skill level described themselves as being able to read or write English “well” or “very well.” Of those in the next lowest skill level, 93-97% described themselves this way.[10]

We’re all low-literacy (at times)

Ever screw up a recipe because you were rushing to finish before the guests arrived and mistook “t” for “T”? Ever been confused while in a foreign country trying to figure out how to use public transportation to get to the Flughafen (airport)? Then you’ve experienced some of the same situations and exhibited some of the same behaviors as people with low literacy skills. When people are tired, under stress, or just plain busy, they may have fewer cognitive resources to bring to the task at hand. And that affects word recognition, inference, problem solving—all the skills you use for reading and understanding. Let me tell you a story from my own experience.

When my son was four years old, he had his tonsils removed. In about 1-2% of cases, patients experience post-surgical bleeding. And that is exactly what happened after my son woke from his nap about a week after the surgery, his mouth full of blood, stains on his sheets and clothes. I called the surgeon’s office, and they sent me to the emergency room at St. Christopher’s Hospital in Philadelphia, where his surgeon would stop the bleeding.

In my panic, I forgot to ask for the hospital’s address, so I looked it up on Google, wrote down the first result I saw, got in the car, and started driving. When I arrived at that address half an hour later, there was no hospital. The address I had written down was for the St. Christopher’s Hospital for Children Foundation, in west Philadelphia. The hospital, my intended destination, was nearly 45 minutes away in north Philadelphia.

The story has a happy ending—I turned out to be a short drive from a closer children’s hospital—but my frustration levels at myself, Google, and whoever wrote the foundation’s home page were through the roof. It was also, as evidenced by the hospital bill, a rather expensive mistake.

This is classic low-literacy behavior: picking the first plausible answer without confirming that it’s the correct or best answer. I don’t have low literacy skills, but for that afternoon, because of the high-stress situation, I behaved like I did.

It’s tempting to think that audiences are coming to our content with the basic skills needed to comprehend and interpret it. That may simply not be the case. Part of “consider[ing] your content from your user’s perspective” is understanding what reading skills the user brings to the equation and writing to accommodate them.

Strategies of low-lit readers

There’s a lot of stuff going on in your brain when you read. First you have to recognize the words in front of you by associating the printed word with the spoken word it represents, a process called decoding. Beginning readers start by recognizing letters. More proficient readers can move past letter-by-letter reading to recognizing individual words. The second part of the process is comprehension—interpreting the meaning of all those sentences and paragraphs.

People with low literacy skills have difficulty understanding what they read because they’re spending so much effort on decoding—word and letter recognition—that they have few cognitive resources left to interpret meaning. They may read every word put in front of them, but because they don’t have much left to attend to comprehension, they take little meaning from what they read.

When you observe someone who has low literacy skills reading, you’ll likely see some of the following behaviors:

  • Reading one word at a time: Observe an eye tracking test and you’ll see that most people fixate on one word out of every three or four. But low-lit readers may fixate on every single word. By spending all their cognitive resources on word recognition, low-lit readers may have little left over to interpret what they’ve read.
  • Taking things literally: Being able to apply what you’ve read to your situation is one of the literacy skill sets. Unskilled readers don’t do this very well, particularly with abstract concepts based on written text. They tend to think in concrete terms.[11] Because they take things so literally, they may not realize that stories or examples used in written text to illustrate a point actually apply to them.
  • Avoiding reading altogether: Low-literacy readers will judge whether it’s even worth their time to attempt to read. They may skip difficult words or entire chunks of text and miss the information they were looking for in the first place.
  • Satisficing: A combination of the words “satisfy” and “suffice,” this refers to the tendency of unskilled readers to stop reading as soon as they’ve found the first plausible answer to what they were looking for, even if it isn’t the best answer or even the correct answer.
  • Retaining little: People with low literacy skills may not be able to store as much information in their short-term memory. Adults with adequate literacy skills can store around seven independent chunks of information at a time in short-term memory.[12] The number for poor readers may be closer to five or fewer.[13] That becomes a problem when you include lots of information (more than five to seven chunks) and expect readers to remember it. When working memory is full but more stuff is coming our way, our brains don’t just discard some of what’s in there, it all gets dumped. So it’s not a good idea to include lots of information in text and hope that some of it will stick; it probably won’t.

Accommodating low-literacy readers

You might be feeling like there is little you can do to accommodate unskilled readers. But take heart: there are plenty of ways to present information that make it easier (if not exactly easy) for low-literacy adults to understand and use it.

  • Make it easy to read: Writing text at an appropriate level can help to ensure that the reader has a better chance of understanding and being able to use the information. Plain language guidelines like using common words and shorter sentences will help.
  • Make it look easy to read: As important as making information easy to read is making it look easy to read. Designing a simple layout with lots of white space, type that is large enough to be easily read, and headings that provide visual cues about the content will make the interface less intimidating.
  • Include only what’s important: Given that it takes so much effort required by low-lit readers to decode text, much less interpret and apply it, you should only cover information they need to know, not what’s nice to know. Focus first on actions the user should do, not the theory behind why it should be done.
  • Be consistent: Using synonyms (for example, alternating between using “dairy” and “milk” at different points in text to describe dietary restrictions for a medication) requires additional cognitive resources. What is often obvious to skilled readers—like using two different words to mean the same thing—requires more work for poor readers to decipher.
  • Provide feedback: Let users know there are a certain number of steps to achieve a desired result and where they are in the process; in other words, provide a light at the end of the tunnel. Provide validation whenever possible. Otherwise, low-lit users may opt out.

Why it matters

Crafting information so that it meets the needs of your audience is hard. Audiences can be inconvenient and unwieldy. They’re rarely homogenous. They probably don’t know what we know. If they did, they wouldn’t need us to fill in the gaps, would they? Writing to accommodate people with low literacy skills may feel like introducing a new set of requirements, but it isn’t really, because we’ve always had a large population with low literacy skills. Those results from the NALS? They don’t really change much from decade to decade.

People with low literacy skills have always been part of our audience. They’ve always needed their information presented clearly, plainly, and simply so they can succeed in understanding and using it. Most of us just didn’t know it. But now we do.

Another common question, “Won’t dumbing down the content make it unpleasant for everyone else?” First, let’s get one thing straight. You’re not “dumbing down” anything, you’re simplifying it. Second, accommodating low-literate adults does not come at the expense of more adept readers. In fact, crafting your content to accommodate this audience has the added benefit of making information easier for everyone to read, understand, and use. Everybody appreciates clarity. So I say the answer to this is a resounding “no.” (For a quantitative comparison of task success, time-on-task and satisfaction for low- vs. average-lit participants using a site designed for low-lit users, read about the study described in Jakob Nielsen’s Alertbox article on low literacy.[14])

And, of course, there’s the self-serving reason revealed by my experience driving to the hospital: one day, that “low-literacy” reader may be you.
