Entitled to be irrational/illogical?

[snowden719]

what about a situation in which you a burglar breaks into your house telling you that he will kill your family if you don't give him the combination to your safe. in this case it seems obviously preferable to be irrational because if the burglar knows you are completely irrational there is nothing he can do to get you to open the safe where if you were rational he could use the threat of harm to your family to get you to open the safe. If you are irrational there is nothing the burglar can do,and would then leave the house as there is no way for him to get you to open the safe. I'm not sure if this is exactly what you are talki.ng about but this and other instances in which being irrational makes you immune from coercion are obvious situations where it would be best to be irrational
