During the game, when you unlock an Ideological Trait, and you exit the Ideology screen, the game always opens the Research screen.
This buggy behavior is there for a very long time and is extremely annoying.

Go to the Ideology Screen.
Choose "Slavemasters" (Greed IV) and unlock it.
Then "Research Complete" screen is displayed, click on "Next" and "Choose New Tech" buttons.
The Research screen is opened and you can also see the tech are gray in color.
This is another bug reported in this post.
