Oh, I hadn't heard of lojban before. Cool project!
Anecdotally, I think language effects the way you think more than most people realise, which is why I think a logical language is a great idea: it might "trick" people into thinking more logically!
Now to get someone to actually speak it with!
If you’ve not heard of Lojban you may not have heard of Sapir-Whorf. Or you’re indirectly referring to it.

I had not! Cool to see that there's a established theory about linguistic determinism(great term btw!)
I was only speaking from personal experience, I moved from Sweden to Brazil in my early twenties and after a while I began thinking and dreaming in Portuguese. I noticed then that my thought process changed(actually, I noticed it upon moving back to Sweden, as my thoughts and dreams shifted back to my mother's tongue. The shift the way back was much faster since I already spoke Swedish whereas in Brazil I had to learn the language before beginning thinking in it)
Anyway, I noticed then that I would interpret the world differently depending on which language I used for my internal monologue. Like way different. It was a curious experience!
