How strong is the science, really?
Meridian Evidence & Causation is an independent practice that assesses the behavioral and neurocognitive science behind social-media platform-harm claims—graded honestly, vector by vector—for the funders, insurers, and counsel who carry the risk of getting it wrong.
The Independent Read
Most evidence you can buy is bought to support a side. This isn't. The assessment maps where the science holds and where it's contestable—including where the plaintiffs' case is weak—because a read you can stake capital on has to survive a coordinated defense, not flatter whoever paid for it. Strictly non-testifying. One side per matter.
What It Covers
A graded assessment of the underlying psychiatric epidemiology and neurocognitive evidence across the harm vectors at issue—depression, anxiety, sleep, attention and working memory, body image, self-harm—each rated for how much confidence the evidence actually deserves. Delivered as a sourced PDF with a one-page executive summary.
On the Method
Every grade uses GRADE—the standard framework in evidence-based medicine for rating how much confidence a body of evidence warrants, from high to very low, based on study design, consistency, and directness. Every study is read in primary form, and the grade reported is the grade the source assigns. Nothing is inflated. In this market, one overstated citation is disqualifying, so the discipline is the product.
Who Does the Work
A clinical-psychology researcher with 500+ citations, a published meta-analysis, and years running large-scale research operations across 3,000+ participants. Evidence synthesis and certainty-grading are the core discipline of the practice—and a discipline I've already done in print.
