Pause on the specific assertion
Ask what the post wants you to believe about the image's date, place or subject. If the claim is consequential, a matching thumbnail is not enough to verify it.
Use a quick evidence check
- Open the linked source rather than only the preview.
- Search the image if the origin is unclear.
- Compare captions on credible publications.
- Leave uncertain claims unshared or clearly qualified.
An old photograph may circulate during a new event because it is visually dramatic. Finding the older source helps prevent an accidental miscaptioned repost.
Avoid adding new claims
Do not identify private people, infer motives or supply a location from vague visual clues. If you share a correction, link to the evidence and explain the specific mismatch. A careful correction should reduce uncertainty rather than replace one unsupported story with another.
Continue with responsible source checking.
