MR uses genetic variants as "natural experiments" to determine if an exposure (like high blood pressure) truly causes a disease (like stroke), rather than just being associated with it. ⚖️ The Three Pillars of MR Validity
: When a gene affects multiple traits independently, potentially biasing the causal estimate.
