Do you edit text messages carefully before sending them? If so, you may be the kind of person who takes pride in crafting even the simplest message.A new book Writing For Busy Readers makes the argument for being the careful kind of writer, even in informal messages. It lays out the data for sharp, simple writing.Todd Rogers and Jessica Lasky-Fink are behavioural scientists, both at Harvard. Their “Writing For Busy Readers” is cleverly titled: all readers are busy nowadays. People are filled constantly with messages, from the mailbox to the inbox to the text-message reminder. What to read, what to skim and what to ignore are decisions that nearly everyone has to make dozens, or even hundreds of times a day.The authors present well-established principles that have long been prized in guide s to writing including The Economist’s style book: cut unnecessary words, choose words everyone knows and keep sentences simple.Take “less is more”. Most books on writing well suggest cutting off needless words. However, in Writing for Busy People, the authors have tested the principles. For example, in an email to thousands of school-board members asking them to take a survey, cutting the length from 127 to 49 words almost doubled the response rate (from 2.7% to 4.8%).The researchers found that a longer message makes recipients (收件人) think the task (such as filling out a survey) will take longer, too. Writers must sometimes choose to be informal but effective instead of sympathetic but ignored. From Facebook posts to online-travel reviews, even brief, informal pieces of writing that follow these rules get more likes, shares and so on. From essays to text messages organizing dinner plans, devoting time to the needs of readers has evident benefits. If you are so busy that you write a badly-organized message that readers scan, ignore and delete, then you might as well have not written it at all.1.
