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 .
A Disney-like educational show for grown ups? I'm under the impression that this kind of plot works well for children shows, but isn't exactly interesting to an adult audience. Relevant TVTropes links: Anvilicious, Author Tract, Eigen Plot, Asspull, and of course Mary Sue.
Moreover, even if the show turns out to be entertaining, there is a very real chance to screw it up into a freak show and tar the word "rationality" much like Ayn Rand tarred the word "objective".
Steelmanning the weird "rationalist" habits you listed in a convincing way would quite difficult, given that most of them are indeed questionable practices.
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.
