It definitely makes a lot of sense. Just try speaking with someone about politics or religion. Even if you conclusively prove that the other persons views are not based in fact or reason they will refuse to acknowledge you are right and then usually get mad and stop talking to you. Humans are most certainly not 'rational beings'. Our thinking is constantly biased by our formative experiences and our environment.
It goes far deeper than that, too. Our raw pattern matching sensitivity is cranked to the max at a very low level, and this hypersensitivity to perceived order ricochets throughout the entire system of data processing that our brain engages in.
We see patterns everywhere, whether they're real or not, and we have trouble unseeing them even once we know for a fact that the data is random, or that the pattern fails. Statistically speaking, we're a freaking mess, we're constantly pulled towards the wrong answers, we never have good estimates about how reliable our inferences are, it's just an all around bad scene.
And yet the combination of all of these seriously flawed pattern inferences leads to a creature that, all said and done, makes pretty damn useful predictions about a lot of things, even if the details of how those predictions get made are all wrong. This is surprising, since typically in statistics when we use algorithms that are too optimistic or sensitive we end up with pure garbage. If I had to guess, humans end up implementing something like the reverse of a typical boosting algorithm, in that we take a bunch of too-strong pattern recognizing subunits, and then put them together into something that pits them against each other to become more robust against mis-prediction, but I don't have any data to back up that assumption, or any clear idea how it might work - which is, I guess, a perfect example of exactly this kind of mental stupidity that we're so commonly driven by.
