People add by default even when subtraction makes more sense
People default to addition when solving puzzles and problems, even when subtraction works better. That could underlie some modern-day excesses.

Muon magnetism could hint at a breakdown of physics’ standard model
After two decades, a new measurement of the muon magnetic anomaly reinforces earlier hints that its value disagrees with standard physics.
