Challenging times come and go and sometimes we can only laugh it off, even if it means getting a little dark. It's fine to laugh at them alone or with a group of like-minded friends. Dark jokes aren't everyone's cup of black coffee, but laughing at them could indicate a genius mind, says Reader's Digest. A new study published in the journal Cognitive Processing suggests that your reaction to dark humor could reveal your intelligence. A group of psychologists concludes in the paper that people who enjoy dark humor or "humor that treats sinister subjects like death, disease, deformity, handicap or warfare with bitter amusement" may have higher IQs, lower aggression and resist negative feelings more effectively than those who dislike it. Regardless of whether you're a genius, there's no harm in letting off steam with some dark humor on bad days. Here are some dark jokes shared by Reader's Digest that you'll apparently only laugh at if you're a genius with a morbid sense of humor.
