The Claim
Polygenic risk scores for suicidal behavior explain up to 1.16% of the variance in suicidal behavior and are associated with a 1.43-fold higher odds of suicidal behavior in individuals in the top quintile of the polygenic risk score compared to those in the middle quintile, indicating modest but statistically significant population-level predictive utility.
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.
A genetic score that adds up many small risks can slightly predict who might be more likely to experience suicidal behavior — people with the highest scores are about 1.4 times more likely than average to be affected, though it only explains a tiny part of the overall risk.
See the scientific wording
Polygenic risk scores for suicidal behavior explain up to 1.16% of variance in suicidal behavior and are associated with a 1.43-fold higher odds in the top PRS quintile compared to the middle, indicating modest but statistically significant predictive utility at the population level.
What the research says
1 studyThe study found many genes linked to suicidal thoughts and actions, which means genetic scores can help predict risk—just like the claim says, though it doesn’t check the exact numbers.
