The first thing is to realize that you don’t have even the irrational belief, because if the map is wrong, it’s worse than useless.
This isn’t always the case. It is fairly easy to find anecdotes of explorers (and especially those in war) that have gotten lost and found their way to safety using the “wrong map”. Sometimes having a map (even the wrong one) can provide just the amount of hope needed to press onwards.
There are far fewer available anecdotes of explorers who persisted in using an incorrect map, became even more lost, and were never heard from again. I suspect this is a matter of selection bias.

Sounds probable.
