Alpha is typically set at either .05 or .01 in behavioral research. These levels have become the standard because they strike a balance between reducing the likelihood of making a type I error (rejecting a true null hypothesis) and increasing the power of the study to detect a true effect. Setting alpha too high (such as .10) increases the risk of type I errors, while setting alpha too low (such as .001) reduces power and increases the risk of type II errors (failing to detect a true effect).
