Marilyn vos Savant's Pen

Origin
Marilyn vos Savant is an author presumed to have the highest ever recorded IQ according to Guinness World Records. Since 1986, she has written "Ask Marilyn," a ‘’Parade’’ magazine Sunday column where she solves puzzles and answers questions on various subjects. However, many have been skeptical due her use of some outdated intelligence measuring tests and errors she has published in her column over the years.

Effects
Anyone who writes with the pen will have their IQ raised drastically for several hours, or as long as the pen is still in their possession. The downside is that the longer you hold the pen, the more people will begin to doubt your 'new intelligence'.
