I'm aware construction workers don't get PhDs. Some people are exposed to certain things from early childhood and others aren't. Some people have a rich ecosystem of pertinent experiences and are surrounded by knowledgeable people and others don't have those assets. People who have no friends or relatives who know anything about X real world physical skill and are googling up info online are often poorly positioned to judge the quality of the info in question. To me, it seems to be a simple and obvious point. I don't know why it seems to be failing to click with you. Ironically, that's perhaps an example of the kind of disconnect I am trying to describe, though that fact seems unlikely to help me make my case.
