That's certainly a challenge to navigate, but not an excuse to completely throw your intelligence away. If a road sign clearly pointing off a cliff, don't drive off the cliff!
If your town is on fire in a sign, possibly outdated, points You Into The Inferno, don't follow it!
If there is a safe spot that you have personal knowledge of, go there despite the directions.
The problem is that every single one of us is an idiot at <many subjects>, and in a large number of them, we don't even know that we are idiots.
