Lowering the probability of making a Type II error (failing to reject a false null hypothesis) often involves increasing the sample size or the effect size, which can lead to a higher probability of making a Type I error (rejecting a true null hypothesis). This is because the measures to reduce Type II errors typically increase the sensitivity of the test, which can also make it more prone to falsely detecting an effect that is not there.
