Read. Understand. Apply.
The Warn Room blogs apply 70 years of research to the practice of alerts and warnings. We show how evidence-based changes to message content, style, and structure can create more effective warnings.

It's time to apply evidence-based guidance to MEP alerts.
An EBONY alert Recent research on effective Missing and Endangered Person (MEP) alerts has identified how to name the incident and how to structure a message to be most effective at helping message receivers to understand and respond to messages. When we consider MEP messages in relation to more general alerts and warnings, they follow the same structure as those warnings that are issued for all hazards. They should always contain the following CONTENTS: The name of the m

A little TEST message can go a long way...
Required Weekly Test IPAWS users are required to regularly test their user proficiency by sending an alert that is issued to users who have opted in to receive them. This is also a great opportunity to demonstrate the type of test message that could be issued during a live test in a community - one that is announced ahead of time, organized with community members, and publicized by the media. These live tests have the added benefit, if done correctly, of growing system awar

Missing person alert types: 40+ and Counting
There are now more than 40 named alerts for missing and endangered persons across the United States. These messages are specific to individual states, and are commonly accompanied by state legislation to identify a vulnerable population that was not previously highlighted in missing persons messages. For instance, Arizona recently initiated the "Turquoise Alert" described this way : A Turquoise Alert program establishes a notification system that provides immediate informat

90-Character messages lead to milling...we've studied it, we've seen it, so why do it?
When we first began to study public responses to Wireless Emergency Alerts in 2012, we immediately saw significant issues with alerts that were limited to 90-characters. Study participants indicated that these messages could not contain enough information to act upon, so instead of leading them to protect themselves, it led to them to search for more information ( see Bean et al. 2016 ). Information search to confirm the message is trustworthy and requires action is commonl

Self-reflections on testifying before congress

Flood Warnings and Technical Language
Much of the time that I have written about language inconsistency and the use of jargon in messages, it has been focused on WILDFIRE. Many previous posts to the Warning Gallery have pointed to the use of operational and technical language (Level 1, Level 2, and Level 3 or Ready status, Set status, Go status) that has more meaning to responders and commanders than to the public. In fact, we’ve published about the use of inconsistent language in the National Fire Protection A

Over-Alerting: Episode 6
CONTENT! Over-alerting is not just about frequency and relevancy. It's also about what you include in the message. Over the past few weeks, I've been writing about the dimensions of over-alerting that Michele M Wood and I defined in our recently published paper Opting Out: Over Alerting in the Era of Wireless Emergency Alerts . The one final dimension is CONTENT. Our study participants explained that messages that are incomplete, incomprehensible, and not actionable,

Over-Alerting: Episode 5
FALSE ALERTS So far, relevance has focused on alerts that require action 🏃♀️➡️ (they are urgent, severe, and certain), alerts that you can actually do something about 😴 (as in, not told to shelter inside when it's the middle of the night), and alerts that are geographically specific 🌎 (you're in the area of the threat and the threat is near you). Today, we'll be talking about that one historical event that is seared into the minds around the world. THE FALSE ALERT. Fals

Over-Alerting: Episode 4
GEOGRAPHY In our research on over-alerting , we found scholars who wrote about the issues of mis-located alerts, polygons, and how geography affects public perceptions of message relevance. In the paper by Sara McBride, Ann Bostrom, et al on earthquake early warnings , they pointed to mis-located alerts as a risk related to technology - that is, when technological issues result in alerts going to places where people don't feel shaking. They can be perceived as over-alert

Over-Alerting: Episode 3
RELEVANCY Earlier this week, in Episode 2, I wrote about the first part of over-alerting, where our research participants described the problem with alert frequency. In Episode 3, I'm going to write about RELEVANCE. This one has a lot of dimensions, and I won't cover them all right now. If you want to read the open access article, click here Sutton J. & Wood, M. (2025) Opting Out. Relevancy was defined broadly by our research participants as "things that affect them."

Over-Alerting: Episode 2
The first dimension of over-alerting: FREQUENCY In our recently published article on Over-Alerting , Michele Wood and I found three primary dimensions to describe over-alerting: 1. frequency 2. relevance 3. content Beginning with FREQUENCY, we found it was described in multiple ways. 1️⃣ To start, we need to consider how frequently a person's phone lights up, vibrates, or emits a noise to get your attention in general. We live in an "attention economy" and one study we

Over-Alerting Series: Episode 1
An Introduction. Just over a year ago, the RAND Corporation published their report assessing public reach of Wireless Emergency Alerts. What stood out to me was not who emergency managers ARE reaching but who they are NOT. In many cases, this can be attributed to OPTING OUT. (25-30% in Texas alone). How do we make sense of this? My colleague, Michele M Wood and I received funding from the US Geological Survey to investigate why people opt out of emergency alerts (if yo
