Using a stringent alpha level and designing the experiment for high power ensures that we have a low probability of making a Type I error (incorrectly rejecting a true null hypothesis) and a high probability of detecting a true effect (Type II error). This maximizes the probability of correctly concluding regardless of whether the alternative hypothesis (H₀) is true or false.
