The portion after the second semicolon is widely paraphrased or misquoted. Two examples are "For every complex problem there is an answer that is clear, simple, and wrong" and "There is always an easy solution to every human problem -- neat, plausible, and wrong."

In some published transcripts or quotations of this speech a variant of this statement appears immediately before the quote by Churchill below, but was not said during Reagan's televised address on (27 October 1964). Though he did make variations of the speech elsewhere it is unclear exactly when and where he may have said used these precise words:
: They say the world has become too complex for simple answers. They are wrong. There are no easy answers, but there are simple answers. We must have the courage to do what we know is morally right.
Later variant: For many years now, you and I have been shushed like children and told there are no simple answers to the complex problems which are beyond our comprehension. Well, the truth is, there are simple answers, they just are not easy ones.
