Psychology/biology:
“Morphometricity as a measure of the neuroanatomical signature of a trait”, Sabuncu et al 2016 (Heritability/variance component estimation generalized to brain volume/thickness: demonstrates that total brain structure—as opposed to just the predictors estimated using underpowered samples, which can only predict like r = 0.3—can predict a large fraction of variance among Alzheimers & aging (~1), IQ (0.95), etc., and so those traits have causal relationships (of some sort) with brain volume/thickness. A common mistake in interpreting brain imaging studies is to argue that, since the state-of-the-art study can predict only a relatively small amount of a trait from their brain imaging data, neuroanatomy is not important; the fallacy here is to treat an extremely loose lower bound as being close to the true total value. By using variance components, however, the total can be directly estimated, and the true total turns out to be far larger. While the causal relationships may not turn out to be interesting (we already knew brain volumes and thicknesses are catastrophically affected by aging and Alzheimer’s), it does at least imply that as brain imaging datasets get larger, they will get ever better at predicting whether a subject has Alzheimers or how intelligent a person is. Hopefully we’ll see variance components taken seriously outside of genetics. If power analysis tells you whether you have enough light to find the needles in the haystack, variance components can tell you whether there are even any needles to look for.
