It decreases with more complex models. A high variance means that the model depends highly on noise and so its solutions vary a lot depending on the particular choice of the data sets (overfitting).

Detailed analysis of Bias Variance Trade OFF WebHowever, if you train the model too much or add too many features to it, you may overfit your model, resulting in low bias but high variance (i.e. the bias-variance tradeoff). In this scenario, the statistical model fits too closely against its training data, rendering it unable to generalize well to new data points.
