Why misinformation spreads in emergencies, how to apply the SIFT method, identify trusted sources, and protect your mental health from news overload.
When disaster strikes, information itself becomes a casualty. In the hours and days following a major earthquake, hurricane, terror attack, or public health emergency, false information spreads through social networks far faster than accurate information — and the consequences can be lethal.
During the COVID-19 pandemic, people died from consuming disinfectants promoted as cures in viral social media posts. During wildfires, false rumours about blocked evacuation routes have caused people to delay evacuation or take dangerous alternative routes. In conflict zones, deliberate disinformation campaigns have directed civilians toward danger rather than away from it. After Hurricane Katrina, false rumours about widespread violence deterred rescue operations.
Knowing how to evaluate information under stress — when your instinct is to act immediately on anything that sounds alarming — is a skill that takes deliberate practice.
Several psychological and social mechanisms drive crisis misinformation:
Information vacuum: In the immediate aftermath of a disaster, official information is slow. Journalists, emergency managers, and officials need time to gather accurate facts. The vacuum is filled immediately by unverified rumour, speculation, and sometimes deliberate falsehood.
Emotional amplification: Frightening, outrageous, or emotionally charged content spreads faster than neutral content on social media platforms. Our brains are wired to pay attention to threat-related information — a feature useful in direct physical danger, but exploited by misinformation.
Source collapse: Normal source hierarchies break down. You may receive the same piece of false information from five different contacts simultaneously — making it feel confirmed even though all five got it from the same original post.
Confirmation bias: We are more likely to believe and share information that confirms our existing fears or expectations. A rumour that "the dam is definitely breaking" will be believed more readily by people who were already worried about the dam.
Speed vs accuracy trade-off: Being first feels more urgent than being right during a crisis. People share to help, not to mislead — but speed produces errors.
SIFT is a four-step information verification method developed by digital literacy researcher Mike Caulfield. It is designed to be usable in seconds and does not require specialist knowledge.
S — Stop Before sharing or acting on any information, pause. The automatic impulse to forward, share, or act immediately is the mechanism that spreads misinformation. One conscious pause before each share breaks that automatic chain.
Ask yourself: Am I emotionally reactive to this? Emotional reaction is often a sign of manipulative content. The stronger the urge to share immediately, the more important it is to pause first.
I — Investigate the Source Before reading the content, check the source. Who published this? Is it a credible institution, a personal account, an unfamiliar website?
F — Find Better Coverage Lateral reading: open new tabs and search for the same information from multiple independent sources. If a claim is accurate and significant, credible news organisations will be covering it.
If you can only find a claim on obscure websites or anonymous social media accounts, treat it as unverified regardless of how many people are sharing it.
T — Trace Claims to Origins Find the original source of a claim. Many pieces of misinformation go through multiple mutations — a photo from a different disaster, a quote from a different person, a statistic from a different context.
Use reverse image search (Google Images, TinEye) to trace photos and videos to their origin. Search the verbatim text of a claim to find its earliest appearance.
During a crisis, not all sources are equally reliable. Use this hierarchy:
| Source Tier | Type | Examples | Reliability |
|---|---|---|---|
| Tier 1 — Primary | Official government and emergency management | FEMA, National Weather Service, CDC, WHO, your state/county emergency management | Highest |
| Tier 2 — Primary | Emergency services official accounts | Police department official Twitter/Facebook, fire department official statements | High |
| Tier 3 — Secondary | Major verified news organisations | AP, Reuters, BBC, NPR, established local newspapers and TV stations | High — but they sometimes publish preliminary unverified reports |
| Tier 4 — Secondary | National broadcast networks | NBC, ABC, CBS, CNN, Fox | Moderate — may contain errors in breaking news |
| Tier 5 — Caution | Social media | Twitter/X, Facebook, TikTok, Nextdoor | Low — verify before acting |
| Tier 6 — Avoid | Anonymous or unverified accounts | WhatsApp forwards, anonymous Reddit posts, unknown websites | Very low |
⚠️ Even Tier 1 sources can issue incorrect information during rapidly evolving emergencies. Officials sometimes contradict each other, issue corrections, or revise guidance. The key is to prefer official sources and update your understanding as official guidance evolves — not to treat any single statement as permanently definitive.
A majority of disinformation involves images or videos misrepresenting the location, date, or context of an event. A wildfire photo from 2018 presented as being today's event. Flood footage from another country. Military activity from a different conflict.
To reverse-image-search a photo:
On desktop:
On mobile:
TinEye (tineye.com) is a dedicated reverse image search tool that shows the earliest known appearance of an image online — extremely useful for identifying repurposed old photos.
For video: The InVID/WeVerify browser plugin (invid-project.eu) allows frame-by-frame reverse image searching of videos and metadata analysis.
Videos are harder to verify than photographs but follow the same principles:
The temptation during an emergency is to share anything that might help — to feel like you're contributing to a solution. But sharing unverified information:
The practical rule: Share only from Tier 1 or Tier 2 sources (official government and emergency services). When in doubt, share nothing and direct people to official sources instead.
Continuous news consumption during a crisis is not the same as staying informed. After the first few hours, the incremental value of each additional news update is small — but the psychological cost accumulates.
Evidence-based practices:
| Domain | Trusted Sources |
|---|---|
| Weather emergencies | National Weather Service (weather.gov), NOAA, local NWS office |
| Public health | CDC (cdc.gov), WHO (who.int), state health department |
| Evacuation and shelters | FEMA (fema.gov), county emergency management |
| Infrastructure (power, water) | Your utility company's official site or social media |
| Natural disasters | USGS (earthquakes), USGS (volcanoes), NHC (hurricanes) |
| Wildfires | NIFC (nifc.gov), InciWeb (inciweb.org) |
| General emergency | Ready.gov, your county/city emergency management office |
| Situation | Action |
|---|---|
| Alarming information received — want to share | STOP: pause before sharing; apply SIFT |
| Unrecognised source spreading urgent news | Investigate source first; search source name + "credibility" |
| Photo or video — is it real? | Right-click → reverse image search on Google or TinEye |
| Need authoritative information | Go directly to official government and emergency management sites |
| Conflicting information from multiple sources | Prioritise highest Tier source; wait for official confirmation |
| Tempted to share "just in case" | Don't — unverified sharing is harmful; direct to official sources instead |
| Overwhelmed by news | Scheduled check-ins twice daily; turn off social media between checks |
| Correcting false information you shared | Post a correction publicly on the same channel; tag the original post |
