The questions suck. It's an interesting idea, but basically a worse execution of Cicada 3301.

I'd suggest using questions that are nothing to do with politics, and also actually falsifiable. Estimation questions could be a good proxy. How many grains of sand on the earth, you gotta be right to two orders of magnitude or the like

Logic questions aren't bad, but don't use ones like in your example because they're badly posed questions. (Of course, many people claim this about any kind of logic question etc)

But ultimately the questions don't matter. It's the existence of any barrier at all, to set a required standard of effort, and to set the tone. Do you want yours to be 'smart person'? Or 'agrees with me ideologically'? Right now it's leaning more ideological than perhaps intended
