Poisoning the well can sometimes be used with the association fallacy, in which an unfavorable attribute is connected with future opponents so that anyone who tries to dispute a claim risks associating themselves with that attribute.
Poisoned-well arguments are sometimes used with preemptive invocations of the association fallacy. In this pattern, an unfavorable attribute is ascribed to any future opponents, in an attempt to discourage debate. (For example, "That's my stance on funding the public education system, and anyone who disagrees with me hates children.") Any person who steps forward to dispute the claim will then risk applying the tag to him or herself in the process.
