COSTA RICA EXTRA – Typos suck. They are saboteurs, undermining your intent. Frustratingly, they are usually words you know how to spell, but somehow skimmed over in your rounds of editing. If we are our own harshest critics, why do we miss those annoying little details?
The reason typos get through isn’t because we’re stupid or careless, it’s because what we’re doing is actually very smart, explains psychologist Tom Stafford, who studies typos of the University of Sheffield in the UK. “When you’re writing, you’re trying to convey meaning. It’s a very high level task,” he said.
As with all high level tasks, your brain generalizes simple, component parts (like turning letters into words and words into sentences) so it can focus on more complex tasks (like combining sentences into complex ideas). “We don’t catch every detail, we’re not like computers or NSA databases,” said Stafford. “Rather, we take in sensory information and combine it with what we expect, and we extract meaning.” When we’re reading other peoples’ work, this helps us arrive at meaning faster by using less brain power. When we’re proof reading our own work, we know the meaning we want to convey. Because we expect that meaning to be there, it’s easier for us to miss when parts (or all) of it are absent. The reason we don’t see our own typos is because what we see on the screen is competing with the version that exists in our heads.
Try this experiment, bet you will be surprised as well that you can actually read and understand the message despite the letters being rearranged.

Intended message
“I couldn’t believe that I could actually understand what I was reading: the phenomenal power of the human mind. According to a research team at Cambridge University, it doesn’t matter in what order the letters in a word are, the only important thing is that the first and last letter be in the right place. The rest can be a total mess and you can still read it without a problem. This is because the human mind does not read every letter by itself, but the word as a whole. Such a condition is appropriately called Typoglycemia.
“Amazing, huh? Yeah and you always thought spelling was important.”
In this study at Cambridge University researchers found that as long as the first and last letter in the word are in the right place, your mind rearranged the letters for you to read the words.
Back to typos and editing. This can be something as trivial as transposing the letters in “the” to “hte,” or something as significant as omitting the core explanation of your article. In fact, I made both of these mistakes when I wrote this story. The first was a misspelling in a sentence that my editor had to read aloud for me before I saw it for myself. The second mistake was leaving out the entire preceding paragraph that explains why we miss our own typos.
Generalization is the hallmark of all higher-level brain functions. It’s similar to how our brains build maps of familiar places, compiling the sights, smells, and feel of a route. That mental map frees your brain up to think about other things. Sometimes this works against you, like when you accidentally drive to work on your way to a barbecue, because the route to your friend’s house includes a section of your daily commute. We can become blind to details because our brain is operating on instinct. By the time you proof read your own work, your brain already knows the destination.
This explains why your readers are more likely to pick up on your errors. Even if you are using words and concepts that they are also familiar with, their brains are on this journey for the first time, so they are paying more attention to the details along the way and not anticipating the final destination.
As any typist knows, hitting keys happens too fast to divert a finger when it’s in the process of making a mistake. But, Stafford says this evolved from the same mental mechanism that helped our ancestors’ brains make micro adjustments when they were throwing spears.
Unfortunately, that kind of instinctual feedback doesn’t exist in the editing process. When you’re proof reading, you are trying to trick your brain into pretending that it’s reading the thing for the first time. Stafford suggests that if you want to catch your own errors, you should try to make your work as unfamiliar as possible. Change the font or background color, or print it out and edit by hand. “Once you’ve learned something in a particular way, it’s hard to see the details without changing the visual form,” he said.
