Thou shalt not assume a therapy administered before an improvement was the cause of that improvement (post hoc ergo propter hoc).
Thou shalt not suppose, because you do not understand an issue, it cannot be true (appeal to ignorance).
Thou shalt not misrepresent your opponent’s position in order to make it easier for you to defeat it (straw man fallacy).
