Quick answer
Social media posts, photos and surveillance video are frequently used in injury claims to argue that a person is less limited than they say. In federal lawsuits, discovery extends to “any nonprivileged matter that is relevant to any party’s claim or defense and proportional to the needs of the case,” and information “need not be admissible in evidence to be discoverable.”[1] Content that is relevant to a claimed injury can therefore be requested.
The scope of discovery
Fed. R. Civ. P. 26(b)(1)
Parties may obtain discovery regarding any nonprivileged matter that is relevant to any party’s claim or defense and proportional to the needs of the case, considering the importance of the issues at stake in the action, the amount in controversy, the parties’ relative access to relevant information, the parties’ resources, the importance of the discovery in resolving the issues, and whether the burden or expense of the proposed discovery outweighs its likely benefit. Information within this scope of discovery need not be admissible in evidence to be discoverable.

Why head injury claims draw scrutiny
Head injury symptoms vary from day to day; HEADS UP notes they “may change during recovery.”[2] A single photo or video from a good day may be presented as evidence that the person is not limited. Most cognitive symptoms, such as trouble concentrating or memory problems,[3] are not visible in photos at all.
Social media
Posts and photos
Activities, travel and events after the injury.
Check-ins and tags
Location data and photos posted by others.
Messages
Private messages describing the injury or the person’s activities.
Pre-injury content
Posts showing what the person did before the injury.
Deleting relevant content can create separate legal problems. In federal court, Rule 37(e) applies when electronically stored information “that should have been preserved in the anticipation or conduct of litigation is lost because a party failed to take reasonable steps to preserve it.” A court may order measures to cure the prejudice, and if the party “acted with the intent to deprive another party of the information’s use in the litigation,” it may presume the information was unfavorable, instruct the jury accordingly, or dismiss the action.[4]
Surveillance
Surveillance video records what a person does in public, such as driving, shopping or yard work. Many concussion symptoms, such as trouble concentrating, irritability and sleep changes, are cognitive or emotional rather than physical,[3] so video of physical activity does not directly show them.
Consistency across sources
The other side typically compares social media, surveillance, medical records, testimony and exam results for inconsistencies. Records that accurately describe both good and bad days are harder to contradict. See everyday evidence.

Frequently asked questions
Can private social media posts be requested in a lawsuit?
Privacy settings do not determine whether content is discoverable. The federal rule covers any nonprivileged matter relevant to a claim or defense and proportional to the needs of the case.[1]
Does surveillance show cognitive symptoms?
Generally no. Surveillance captures physical activity, while many concussion symptoms are cognitive or emotional.[3]
