Consider the argument:
Prisoners that have been kept in solitary confinement consistently have higher recidivism rates (they recommit crimes upon release from prison). So solitary confinement (is bad for society since it) leads to recidivism.
This argument is best characterized as:
a. A sampling argument (or inductive generalization)
b. A circumstantial ad hominem
c. An appeal to ignorance
d. A Post Hoc argument
