Frostpunk 2

Sceptical is the level immediately below neutral. If the relations bar becomes red ever, you've failed the achievement. Probably not doable in story mode due to the civil war being scripted. In a way, this is the almost the exact opposite of Consistency because you will need to almost immediately build or pass a law of the opposite affinity after every building or law to keep your relations balanced. Focus a little more on the communities as you cannot promote or use secret police on them to increase relations the way you can with factions. If you can, try to spawn the Bohemians (adaptation, equality, reason) as their devoted passive is to raise relations with a random community. Don't be too fanatical with the cornerstone not represented by your communities though, as the opposing faction can immediately spawn with negative relations. In almost every game I played, raising funds and then passing a law against them at the beginning turned them to sceptical, so I would avoid using that or at least hold off until they're at least favorable. If possible, try to finish the game early, as the more down the zeitgeists you go, the stronger their opinions of the direction become. It's not impossible to manage, but much more difficult.
