COMMONSENSE BELIEFS -

Most Aussies are fighters. John is an Aussie. So we believe that he is a fighter. John and Jack are friends. Friends know what they are doing in their lives (like studentship, job or business or whatever). So we believe that John and Jack know what the other is doing in his life. This works because knowing what the other does is BECAUSE OF the fact that they are friends. However, at the same time, that doesn't mean that all friends will know about each other. Note : this belief system works, it doesn't mean it's necessarily always true. But if I say this road is accident-prone (because there have been many accidents on this road), then it is wrong to be scared of the “road” per se because the cause might be a building on the road from whose terrace some miscreants who live in that building throw stones at cars. So the road is not per se the cause of the accidents. However, at the same time, the generic fact remains the same that you should be scared of that road till you don't figure this out since from the human mind’s perspective, correlations are the precursors to arriving at / detecting causes. If most parents love their children we say parents love their children. Commonsense fact/belief : A --- B most of the time. If a is a sample of a, then a---B. This is true only if ‘A’ness is the cause of A----B. That is, the link A----B should be true causally because of A. So if I say (most) Aussies are fighters. Then believing that a given Aussie is a fighter is right only if “being an Aussie” is the cause of the fighting spirit of the Aussies.
