Today, the International Organization for Standardization (ISO) released Part 3 of its plain language standard, which is focused on science writing. By making science information clearer for all readers, the standard benefits those who create science information and the public who reads it. 

• For science authors, the standard will help them transfer their knowledge to wider audiences. It will help comprehension and accessibility of scientific information without sacrificing scientific accuracy.
• For the public, the standard will make it easier to find, understand and use scientific information. Research shows that communicating science in plain language helps people make better decisions based on evidence. In addition, accurate, clear scientific information can help combat misinformation.

Gael Spivak, who chairs an International Plain Language Federation committee that supports implementing, adopting and localizing the ISO plain language standards, explains, “When you’re communicating science to the public, it’s essential to recognize that readers will have a wide range of backgrounds in science. Because of this, science authors need to adapt scientific language and knowledge so that they provide their intended readers with relevant information they can easily find, understand, and use.”

Stephen Bernhardt, who chaired the drafting committee, elaborates that “This emphasis on clarity will help increase science literacy among the broader public. As a result, the standard will help science authors enhance people’s engagement with science-based information. This will also help build the public’s trust in science information through transparency.”

 This plain science language standard is referred to as Part 3 because it builds on Part 1, which sets out general principles and guidelines. Part 3 adds content specifically relevant for authors creating science information. Other parts being developed include one on document design and one that organizations can use to get ISO certified.

You can buy a copy of the standard through your country’s standard-setting body, or directly from the ISO store.
