There’s NO WAY to improve “Common Sense” (such a silly and uninformed concept) but there are REAL strategies one can implement to improve “Common Knowledge!”
Share a story! Do a hazard assessment with someone. Tell a story about when you’ve failed to see a hazard and you paid the price or ALMOST paid the price. Ask questions of others! “How do you do….(fill in the blanks).”
These things are activities we can all do to increase our common knowledge.
