The Silent Witness Blog
Writing for the people who work the file. Adjusters, SIU investigators, plaintiff and defense attorneys, biomechanical consultants. Every post explains a specific piece of the claim, the collision, or the litigation, grounded in physics and the medical record.
Most writing about crash reconstruction and biomechanics sits in one of two places. On one side, the peer-reviewed journals that speak in terms only reconstructionists read. On the other, the marketing copy that tells you a tool is "intelligent" and moves on. Neither helps the person who has to evaluate a $75,000 demand on a rear-end file before lunch.
This blog tries to fill the gap. We write for claims professionals and attorneys who are sharp, busy, and want to understand what the physics actually says about the file in front of them. When we talk about Delta-V, we explain how it's calculated, where the numbers come from, and what a 9 mph range means for the injury probability you're being asked to accept or deny. When we talk about deposition-ready documentation, we show what holds up and what doesn't.
Every post is written by, or reviewed by, someone with direct experience in biomechanics, crash reconstruction, or claims operations. We cite NHTSA and IIHS data where it matters, disclose our assumptions, and try not to tell you anything we can't defend at trial. If you're new to the field, start with the primers on Delta-V and AIS scoring. If you've been in claims for twenty years, skip to the pieces on how AI-generated evidence is being challenged under Daubert.

Six areas we write about most. Each category has its own archive with the full history of posts in that space.
Crash Reconstruction
Delta-V, PDOF, crash pulse, EDR data, and photo-based reconstruction methods. Written for claims professionals and attorneys who need to know how the numbers get produced, not just what they say.
Injury Analysis
Biomechanical injury causation, occupant kinematics, whiplash and soft tissue probability, MIST claims, and AIS scoring. The science that connects crash forces to the injuries adjusters see on the medical bill.
Insurance Claims
Severity triage, fraud detection, damage-versus-injury mismatch, bodily injury evaluation, SIU workflows, and how AI is changing day-to-day claims operations.
Legal Technology
Daubert and Frye standards for AI-generated evidence, deposition preparation, admissibility trends, expert witness economics, and what litigation looks like when physics analysis is produced by software.
Product Updates
Platform releases, capability additions, and changes to how Silent Witness handles crash and injury analysis for claims and legal teams.
Industry Research
Original data analysis, trend commentary, and longer-form research on the intersection of accident reconstruction, biomechanics, insurance claims, and personal injury litigation.
About this blog
Silent Witness is an AI-powered platform for crash reconstruction and biomechanical injury analysis, used by personal injury attorneys, insurance carriers, SIU investigators, and TPAs. This blog is our writing practice. We publish one to two new pieces a week, and every post is grounded in either the physics, the medical literature, or the operational reality of running a claim.
We're based in Santa Monica, California. Our analysis has been cited on CNN, ABC, The Wall Street Journal, Fox Business, and Discovery Channel. The writing here tries to be practical first. If you've got a request for a topic, or a file you'd like to see worked through in a post, send it over.
