Superstition is a comfort reaction a thing to blame or thank and also relieves people of pressure when necessary. Religion is also similar to superstition it is based around reassuring people when they are doubtful and helps them to relax. It also gives them "somebody" to talk to in moments of pain or suffering. An example of religion being a reassurance is when a loved one dies. People say he is in a better place now. That is merely a way of letting them put their minds at rest about the future of the deceased as well as their own.
Many people who are superstitious won't admit to it - until you ask them to walk under a ladder, or break a mirror. There's no logic behind it, no matter how many times we try to explain superstitions by saying things like "Well, walking under a ladder could get something dropped on you". At the end of the day, human beings hold onto superstition not because we believe its logical, but because it lets us believe, or pretend to believe, that we have control over the uncontrollable - our fate.
Superstitions are beliefs people have about the causes of events. They often arise because two things happen at the same time; for example, a person might win a bingo game while wearing a particular hat, which then becomes the "lucky" hat. Or a student passes an exam while using a certain pencil. There are no logical causal relationships between the hat/pencil and the "result."
Superstition is a belief that is not grounded in reality and defies logic, thus any superstition lacks logic. Otherwise it wouldn't be a superstition. Superstitions are usually based around a lucky object, lucky numbers, or unlucky days of the year like Friday the 13th. There are never any factual arguments to back up said belief.
Claiming it logical to refute something without proof, is illogical. Sure, there are some crazy ideas swimming around, but we barely know anything about anything. It was once unreasonable to fly. They were very sure about that 'fact', which was not a fact. It's in fact important to remember that we don't know anything, a closed mind can't realize the unimaginable.
Superstition does not at all lack that of logic. Somebody can easily have a feeling of something that happened or what they think may happen in the near future. They may be basing this on logical events of some sort thus making it indeed logical for somebody to have a superstitious feeling.
If we think about the concept of superstition, we get a causality link between an act and a fact apparently totally unrelated. In this sense, there is a logic thought by the person, even if the relation between premises and conclusion can not be understood as accurate or plausible. Therefore, one can say it is a faulty logic.
