People who are different are considered ineffective. People who can’t hide their shortcomings are not considered a threat. A lot of spies rely on being unobtrusive, but we flat out flaunt the fact that we’re different, and those we try to get information from put us on an even lower level than the ones they don’t notice. They don’t believe we’re even capable of being a threat, and they misstep more than they might with someone they simply don’t know.
