Document Summary
The fact that some bad outcomes can be caused by different factors is called: equifinality. The fact that any given risk factor (e. g. , early life trauma) can increase the risk for multiple bad outcomes is called: multifinality. Below are two statements about genetic risk for psychopathology: risk for psychopathology is significantly heritable for many psychological disorders, the effect of individual genetic variants in terms of increasing risk is very small, they are both true. The missing heritability problem: heritability by twin studies vs. common variants. Using twin studies design gold standard to see how heritable a disorder is monozygotic vs. dizygotic. There are a number of snv that are more likely to show up in individuals with a specific disorder. Overall heritability is a lot lower when you are only looking at common variants. The missing heritability problem snp"s only account for a portion of the heritability (at least 1% or more of the population)
