“Would Contact with Extraterrestrials Benefit or Harm Humanity? A Scenario Analysis” was written by Penn State student Seth D. Baum and post-doc Jacob D. Haqq-Misra and Shawn D. Domagal-Goldman a post-doc in NASA’s Planetary Science Division. The report looks at the possible types of extraterrestrial intelligence humans might encounter.
Its important to note that this was not a "NASA report." It's not work funded by NASA, nor is it work supported by NASA in other ways. It was just a fun paper written by a few friends, one of whom happens to have a NASA affiliation.
