A fallacy is an argument that uses poor reasoning. An argument can be fallacious whether or not its conclusion is true
Faulty Causality/Post Hoc
Faulty causality (sometimes called Post Hoc) is a rhetorical fallacy in which the underlying assumption is that if one event happened before another, the first actually caused the second. This clearly isn't always the case.

Character: Giles Corey
Quote: “Last night—mark this—I tried and tried and could not say my prayers. And then she close her book and walks out of the house, and suddenly—mark this—I could pray again!” –Act 1

Explanation: In the frenzy of witchcraft accusations, Giles Corey states that he believes his wife is guilty, saying that he couldn’t pray when she had her books out. Just because A happened (she read her books) doesn’t mean that it caused B (Giles couldn’t pray). Could also be seen as since she stopped reading, he could pray.

Character: Mrs. Putnam
Quote: “I knew it! Goody Osburn were mid-wife to me three times. I begged you Thomas, did I not? I begged him not to call Osburn because I feared her. My babies always shriveled in her hands!” –Act 1
