I don't think this is possible. A show with consistent interactions between the same people needs either an external enemy or internal strife to keep it interesting. Shows like Always Sunny rely on the main character's biases, stupidities, and selifshness to generate strife within the group. A rationalist house would simply not be this way. Rationalists who hate each other would find some sort of system by which they can minimize interaction along dimensions they hate (maybe scheduling separate mealtimes if one is a vegan) or simply move away. As far as external enemies go, you're creating a very different kind of show.
I imagine the rest of the world outside the house to be and bearing in mind that no one is perfectly rational; and most people you find will be still on their journey of "getting better". I imagined my characters to only be "most of the way there".
They may appear to be incongruently on their way to rationality (aka - better in some areas than others). But such is the nature of the journey. For we are not all naturally born saints.
There is a lot of rationality to try to have it all there at once. It would have to be an imaginary &qu...
At the Australia online hangout; one of the topics we discussed (before I fell asleep on camera for a bunch of people) Was writing a rationality TV show as an outreach task. Of course there being more ways for this to go wrong than right I figured its worth mentioning the ideas and getting some comments.
The strategy is to have a set of regular characters who's rationality behaviour seems nuts. Effectively sometimes because it is; when taken out of context. Then to have one "blank" person who tries to join - "rationality house". and work things out. My aim was to have each episode straw man a rationality behaviour and then steelman it. Where by the end of the episode it saves the day; makes someone happy; achieves a goal - or some other <generic win-state>.
Here is a list of notes of characters from the hangout or potential topics to talk about.
