Chapter 14 - Visual Representation of Risks
The chapter argues that visuals help audiences understand and recall the content of risk better. Information can be forgotten, but people have stronger visual memories and tend to remember things they have seen in picture form better. This reminded me of something that I had experienced when I was ten and still impresses me when I think about it.


Visuals are helpful in clarifying abstract concepts. For example a gas leak is abstract if you have not lived through one. No matter how much you read about it, seeing pictures of what to do step-by-step may be easier to recall during the event. Visuals can be powerful tools to explain various aspects of risks and they enhance understanding about the risks.
When you designing a certain visual for a specific use, you need to consider the audience’s information needs. Most of the time, you want to cover what people want to know in a certain risk situation, but you will also need to carefully determine and place information about what people may need to know.
Another important factor you need to keep in mind when designing visuals is where and how they will be used. If you are designing something for elementary school children, you need to determine what will be attractive and interesting to them, and what will they remember easily. Mental models might be important at the design point of visual risk communication materials since how people perceive something will also be a result of what they have in their minds. If you can incorporate what people already have in mind with what they need to know, that visual will be attractive, easy to understand and also easy to recall.
A major point emphasized towards the end of the chapter is the need to pretest your visuals with people you plan to use them for. Feedback might be important for you to determine what else you can include to make it more understandable, or even address some misconceptions or missing information they will benefit from learning.
