Self employed

Re: Self Employment tax vs regular income tax, now I am unclear why she owes less with Self Employment. Should not Miscellaneous Income / Other Taxable Income be taxed at 10%, whereas Self Employment is 15.3%? Entering Miscellaneous Income / Other Taxable Income seems very straight forward, not much there that I could have entered incorrectly.
