Man and alien encounter

Wake up alien believers, Seth D. Baum et. al. wrote a paper [ "Would Contact with Extraterrestrials Benefit or Harm Humanity? A Scenario Analysis" ] discussing the possible scenarios of man and alien contact.

Abstract

While humanity has not yet observed any extraterrestrial intelligence (ETI), contact with ETI remains possible. Contact could occur through a broad range of scenarios that have varying consequences for humanity. However, many discussions of this question assume that contact will follow a particular scenario that derives from the hopes and fears of the author. In this paper, we analyze a broad range of contact scenarios in terms of whether contact with ETI would benefit or harm humanity. This type of broad analysis can help us prepare for actual.
