"They need to reveal what they know to use it to thier advantage."

your too optimist, isnt about the knowledge you have, lets say, that they reveal some kind of ETs, but dont know how they talk, how is their tech, etc..., then a psico-nut comes and say "i know", haha that will be great, the worls isnt filled by "educated" ppl, the world is more made by desperate ones

if the world would be made mostly by boring rational people...the religions shouldnt exist
