May 14, 2019 at 10:13 comment added Richard Hardy $R^2_{adj.}$ is an unbiased estimator of the population $R^2$ under the null hypothesis that all the variables have zero slopes in population, which is not a very interesting case. $R^2_{adj.}$ is not necessarily unbiased in other, more interesting cases, and whether one should prefer $R^2_{adj.}$ to $R^2$ or not depends on the true slopes.
