It seems like the terminology in game isn't as clear as it should be.  I'm currently trying out the Yor in Beta 5 and got the powerful drug colonization event, since morale doesn't really do much at the moment I ignored it and chose the malevolent +30% to production.  It turns out that's only to manufacturing.  While that is nice, its not as good as a production bonus like from the economic starbase which does seem to add to base production not just manufacturing.  I haven't systematically looked for where else this issue pops up, I thought it worth pointing out and suggesting a look through the bonuses and descriptions to make sure they match up and are accurately describing the bonus you will receive.
