99.99999% of problems in a game come from not blowing the whistle. the "default" that most new officials have (which carries over to their later years) is to not blow the whistle.

Followed very quickly by calling every little piece of contact a foul. This stage lasts longer, IMO, so I consider it more common at lower levels.
