The Claim

Suicidal behavior, including suicide attempts and death, has a SNP-based heritability of 6.7% on the liability scale, indicating a measurable but modest polygenic contribution to the population-level risk of suicidal behavior.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Genes play a small but real role in why some people might be at higher risk for suicide attempts or death by suicide, with about 6.7% of that risk linked to common genetic differences.

Suicidal behavior (suicide attempt or death) shows a SNP-based heritability of 6.7% on the liability scale, indicating a measurable but modest polygenic contribution to population-level risk.

What the research says

1 study

  1. Study: Genome-wide association studies identify 77 loci for suicidality and provide novel biological insights

    The study looked at genes linked to suicidal behavior and found that genetics can explain up to 6.7% of the risk, which matches what the claim says.
