I was over at "my bloginality" lately and found it interesting that a lot of the ISTJs who posted comments agreed that they have a hard time saying "no" to people and can also be something of a push-over. I think there's some truth to this, even though they can be very stubborn, they also seem to let their sense of responsibility cause them to do things for people they don't really want to do. I also think it's true that ISTJ males like to wear mustaches. Most of the ISTJs that I know have mustaches. Makes me wonder which types like to wear beards. I know one old guy who I think is an ESFP and he has a thick beard.
