In 1989, a remarkable interview took place on CBS’s 60 Minutes. Before 40 million viewers, the acting administrator of the Environmental Protection Agency, Dr. Jack Moore, sat in the hot seat as reporter Ed Bradley grilled him about the possible harmful effects of a chemical (Alar) used to treat apples.

At the time, Dr. Vincent Covello had a keen interest in the interview. The year before, Dr. Covello had published an EFA policy document titled “The Seven Cardinal Rules of Risk Communication.”

The situation had everything: heroes (60 Minutes), villains (the EFA), and victims (the children subjected to a possibly cancer-causing additive). As the interview played out, Dr. Covello watched in near disbelief as his recommendations for risk communication went largely unheeded.

This is the case study that opens chapter seven of Dr. Covello’s most recent release, Communicating in Risk, Crisis, and High Stress Situations: Evidence-Based Strategies and Practice.

As readers will learn, the case study shines a bright light on public perceptions of risk and the ways these perceptions play out in the media.

Our previous post previewed the sixth chapter of Dr. Covello’s must-have resource for risk communicators. Below, we’ll look into the seventh chapter, “Foundational Principles: Perceptions, Biases, and Information Filters.”
