I hear that blind people excel in their other senses, which makes sense since the brain doesn't have to worry about processing ocular information and such. However, that's like saying that blind people are gifted with the basic mechanism, such as hearing but ten times better. And that doesn't make sense. So, it's no doubt that they're handicapped but that doesn't necessarily mean they're more or less susceptible to paranoia. It's a state of mind that is achieved through poor thinking, a guilty conscious, etc. I'm typing as I think too, perhaps you should type a little more?
