Dr. Peter M. Sandman Introduction to Risk Communication and Orientation to this Website This page has two purposes. The most important fact about risk communication is the incredibly low correlation between a risk’s “hazard” (how much harm it’s likely to do) and its “outrage” (how upset it’s likely to make people). If you know a risk is dangerous, that tells you almost nothing about whether it’s upsetting. If you know it’s upsetting, that tells you almost nothing about whether it’s dangerous.
