In the case of predicting personality from smartphone behavior, according to a priori estimation by the formula, the expected out-of-sample R² of OLS is insufficient to exceed the sample mean baseline (i.e., it is less than or equal to 0), whereas the expected performance of ridge regression can surpass that baseline.
