Social bonus is fixed as of 1.0X
PQ bonus does not work correctly - it will only affect your homeworld and not any subsequent colonies
Research bonus operates in a very odd way that ends up with it being half as effective as advertised. E.g. +50 research becomes +25
Pop growth is useless because of the way the current system works. You'll hit the cap on growth very easily without bonuses.
As far as I can tell, creativity does nothing. I could be wrong on this one.
Soldiering bonuses are pretty useless in my opinion - the bonus you get for being the attacker is large enough to make soldiering a luxury at best. Also once you research planetary invasion, the rest of the soldiering techs are easy to get.
