in the real world, the penalty for being wrong is HUGE
In some situations (committing an integrated circuit design to manufacture probably being one), the cost of being wrong is pretty big.
Other situations where there's a tight feedback loop and you can make/propagate changes quickly (say, most web app software development), it's less so.
True. But generally the cost of guessing and doing something wrong is much higher than saying "I don't know" and asking someone else or Googling the result. School, through homeworks and especially exams, trains us to do our best without outside help. I would argue that this behavior is maladaptive to engineering in the real world.
