I didn't find this info anywhere, so I'm asking.
I've read about the bonuses/penalties for the diplomatic relations with other races being dependant on your ethical standings, on your military superiority etc.. That's IMO a great system.
The question is whether a newly met alien race automatically gets these bonuses and penalties at the moment you've met them or are first contacts not burdened with this and the standing change accordingly to your knowledge on their race and vice versa?
Also is it possible to find an alien race (spy ship?) without their knowledge? So that you would be able to know more about them before making contact - perhaps even greeting them with an invasion if you think the race is totally incompatible to yours?
