A Bruce Schneier describes a series of experiments in logical thinking, some of our security blind spots on the light come through the essay of IEEE Security & Privacy:

consider the Wason selection task. Topics are presented with four cards side by side on a table. Each card represents a person, with each side listing some statement about this person. The theme is then typically given and asked which cards turn around, to ensure that this rule meets the four people he had. "For example may be the general rule, If a person travels to Boston, then he or she a plane takes.", the four cards can match travelers and have a target on the one hand and a means of transport to another. On the page related to the topic, read: "went to Boston," "Moved to New York," "took a plane", and "a car." Formal logic says that the rule is violated when someone comes to Boston, without an aircraft. Translation in Propositional calculus, it is the general rule: If P and Q. The four cards are "P", "not P," "Q" and "not Q." To ensure that "If P, then Q" is a valid rule out, verify mode of Ponens by turn over the card "P" and make sure that the opposite says "Q." If mode Tollens want to check, select the "not Q" card and make sure that the opposite will not say, "p".

Move back, for example, you must have the "show went to Boston" to ensure that the person took a level, and you must have that "took a car" card to ensure that this person is not going to Boston enable enable. Non-need to denken-how many people - you then "took on a plane" show to see, whether it says "moved to Boston", because you do not care. The person might use to Boston, New York, San Francisco and London. The rule says only that people who fly to Boston; it break the rule, if someone somewhere else flies.
