I'm finding lately that I have a really hard time trusting people. This isn't just asking someone to do a simple task, and isn't always as serious as trust in a relationship. I have a very difficult time putting my faith in other people. I've been let down too many times. I know people have lives, blah blah blah. It's caused me to live by the philosophy that people are guilty until proven innocent.
Do other SJ's have this problem? ISTJs?
