I question its value because it tends to rely on assumptions and personal observations vs what I consider to be more objective forms of data gathering and synthesis, such as science. What is your opinion?
Common sense (to me) seems to serve a more important role when science, data gathering and logic aren't possible or present.
Logic and common sense, however, sometimes are quite related - and maybe even dependent on each other. If you are without common-sense, your logic suffers. If you are without logic, your common sense suffers.
Like: Yesterday I told my son the other day to get some lunch meat from the fridge so I could lure a dog out from under the deck. An adult - or other child (like my daughter) would have looked for the lunch meat and, if there was none, would have considered dog-edible suitable options: hot-dog, cheese. . .
My son, because of his underdeveloped common sense due to their developmental disorder, brought me a frozen package of bologna from the freezer instead of something I could actually feed to the dog. he didn't see lunch meat in the fridge, so naturally, the freezer seemed to be the next best choice.
Logic, without common sense, is vapid
My oldest son has a more extreme issue when it comes to his lack. He, also, functions without common sense - but is very heavy on logic. Thus, his actions are to the extreme opposite of his brother's - purely lacking common sense but still functioning within a logical reason.
If I asked him to bring me lunch meat from the fridge, if he didn't see it, he would have brought me something akin to it - his reasoning is: "I see no lunch meat, I do see meat, I do see lunch condiments." Since the dogs don't eat a "lunch" the only logical conclusion to him would have been to get something related to "human lunch." So bread, mayonnaise or jelly would have been his likely choice.
It really depends on who you're talking about, the situation they're in, and if they have a fully developed 'common sense' 'logic' or a balance of both.
