Depends on how you look at it. I believe this "perfect" species would be quite moronic. You can never think entirely rational as that would be quite horrible. At least until you come to the the point where you cannot find a rational reason to continue your existence/eat chocolate/drink alcohol/..., because you likely will not find one. And different people have different ideas what they deem important or not and that is completely fine. That said, it is important to deliver rational explanations to the largest degree possible. The recent trend to "curate" free information is quite destructive. Even if that information is just nonsense. We also have some form of "endorsed" nonsense authorities would like us to believe and you probably should not. The panic about "those other people might believe something wrong and that is a problem" is a disease that should be overcome and you should adapt accordingly.
