This is a great question. I feel like alcohol impairs my judgment, while tiredness impairs my thinking. In general most day-to-day technical tasks require thinking rather than judgment. Then again, this might just be selection bias because I've never been drunk during business hours (but have been called after hours while drunk) but am frequently asked to weigh in on something right after I sign in but before I've had coffee.

I wonder how the context by which these enter the production environment affect the relevant harm caused by either. For example, drunkenness happens via escallations to those not on call, while tiredness comes into play routinely and at all levels.

As a result drunk individuals usually are facing narrow technical problems where thinking is required, and judgments already made, while tired people are facing the whole situation.
