Why Clear Writing Means Aiming for the Lowest Common Denominator - and then Some by Philip Yaffe

I asked the boy (he was 14 years old) what he really wanted to do while he was in my house. "I want to take a hot running shower," he replied. This, of course, was not just a luxury in his home village; it was not even a possibility. A shower there meant filling a jerry can with water, heating it on an open fire, then pouring it over your head.

We had some friends near by we wanted to visit. I took the boy into the bathroom and meticulously showed him how to regulate the butane tank (no central heating in my house), how to adjust the temperature and water flow, how to position the shower head, etc. "Now, when you are finished, I want you turn everything off and go to go to bed," I said. We then set off down the road.

About a half hour later, I thought it a good idea come back and check up on him. I went into the bathroom and I was pleased to see that he had correctly turned off both the water and the butane exactly as I had shown him. The light was still on in his room, so I went over to say goodnight. When I opened the door, I saw this poor kid lying on the bed with his hands over his eyes trying to sleep.

Then it hit me. I had shown everything to him except the most obvious - how to turn off the light!

He of course knew about electric lights, theoretically, but he had never actually seen one. His experience was with kerosene lanterns, which you turn off by blowing out the flame. If you have never actually used an electric light, there is no obvious connection between that button on the wall and that brilliant bulb on the ceiling.

The poor kid simply didn't have a clue. More importantly, I simply didn't have a clue either. As meticulous as I thought I had been, it just never occurred to me that I had failed to give him adequate instructions.

I had a number of such experiences in Tanzania, none of which had anything to do with lack of intelligence. Because of fierce competition to get into school in the first place (the country hardly had any schools), these students were not just intelligent, they were the cream of the crop.

Why Simplification Isn't "Dumbing-down"
 

Someone once said: "Nothing is so simple that it can't be misunderstood." I have always tried to live by this maxim, with my experiences in Tanzania as a constant reminder to simplify to the extreme. But the objection can be raised: "Isn't aiming at the lowest common denominator patronizing?" Yes it is, but mainly in the mind of the writer, not the reader. The fact is, no matter how hard you try, you can never know for certain what each individual reader knows and doesn't know about your topic. What you can know for certain is that if you say something they don't understand, you will lose some (if not all) of their attention.

It is of course necessary to make some assumptions about your readers' level of understanding. However, you should make as few as possible. Those readers who are already knowledgeable about what a particular section of text is saying will either skip it or appreciate the reminder. Those who are less knowledgeable will be grateful for your clear explanation.

Throughout my 40-year career as a professional writer, I have produced press releases, sales brochures, speeches, instruction manuals, training programs, etc. I can recall no occasion where someone complained that my text was "too simple". However, I distinctly recall several occasions where someone said, "I thought this subject would be extremely difficult, but I understood everything you wrote. How did you do it?"

Now you know; it was by aiming for the lowest common denominator - and then some.
