Cryptic labels waste cognition. Human labels return it. “Group A” is fog. “Early-season cohort” is a map. Same data, different friction. Communication is part of the method, not an afterthought. If you want people to reason well, lower the decoding cost. Name variables so a beginner can argue with them. Because argument is learning. And learning is the product. Ask yourself: would a smart outsider understand this table in 30 seconds? If not… rename it.
