Two-tailed tests are more conservative than one-tailed tests because by using a two-tailed test, you are determining the possibility of a causality between variables in both directions, unlike a one-tailed test where y</span>ou are determining the possibility of a causality between variables in one direction only<span>.

Additionally, t</span>wo-tailed tests are less powerful than one-tailed tests because a two -tailed test has its alpha value set at half the value of a one-tailed test (.10 for a two-tailed test and .05 for a one-tailed test).
