The superstitious are an odd lot. They have fallen into post hoc ergo propter hoc in extremis and can't get up. For them, all things that precede are potentially causal to any thing that may follow. In fact, the selection of which cause on which they depend is more intensely valued for an absence of any degree on demonstrable causality. The nature of an epistemological truth bearing connection is a mystery to them but that mystery leaves them believing the least supportable.
If an intelligent person is one who can apply the information learned in the way which they were taught to apply it (in other words, a linear way) and an intellect is one who can validly connect information learned in ways not taught (a lateral way) then the superstitious, while they might be intelligent, are faux-intellects. They make unsupportable lateral connections. They claim causes and point to relationships for which there is no epistemological defense.
For the unbeliever in Christianity (who is "without hope or God in the world") and who is ignorant of where truth comes from, there is a desperate need to fill their world with explanatory notes. So superstition becomes a fake metaphysic and a fake intellection.
Within the Faith there is a similar camp ("who base their faith on visions and are puffed up without reason by their sensuous mind"). They are the "rocky ground" on whom the Word of God is sown and whose acceptance of the Gospel lacks root and depth. And just like the superstitious, they cast about for any proffered myth (as replacement filler) with Christian terms to also build a fake metaphysic and fake intellection.
II Timothy 3:6-7 For among them are those who make their way into households and capture weak women, burdened with sins and swayed by various impulses, who will listen to anybody and can never arrive at a knowledge of the truth.
If they ever hold the truth, it is only by accident. It is never because they need the truth but because they need to believe and since they lack the guidance of truth bearing commodities they "listen to anybody" and fill their devotional library with the ridiculous.
