@reasoning logic,
I took a quick look at the thread. An interesting subject for sure. About all I can say is that I agree with what is now heard fairly often, that common sense is not very common anymore.
Having grown up on a farm in Oklahoma, I think farmers learn common sense or they do not survive, either physically or financially or both, so they know what it is. For example, if you drive your tractor into a mudhole and spend a half tank of fuel and half a day getting out, it is common sense not to repeat the mistake on the next round around the field. Yet there are people that will repeat that same mistake. Another example, my granddad, who was born in 1868 and never finished grade school I don't think, he called cigarettes "coffin nails" way back in the early teens and twenties and taught my mother that. He considered it common sense, but I guess millions of people never figured it out and waited for the government to print the warning on the cigarette packages about them being hazardous to their health. Some people have common sense and others do not, and I cannot explain why some do and some don't, reasoning logic.
