A few things.

First, I have actually been through a process of diagnosis that I submitted myself to for this very purpose -- to uncover whatever underlying neurological issue I had. They found nothing out of the ordinary, and I function perfectly well. I am well adjusted, not on medication, and otherwise "normal."

Second, comments like Eli's about the lottery aren't fair, because I never claimed to be omniscient, only to have some sort of extra perception.

Imagine a scenario in which the world is filled with deaf people. Human beings have never had a sense of hearing. I, through some genetic quirk, am born with a sense of hearing, however faint it may be, and I am faced with convincing the people around me that I can "hear." My first obstacle is to explain what hearing even means to someone who has no basis for understanding it.

Even if they were able to form a mental image of what a sound might be like (I'm not sure how they would, but for the sake of argument...), they wouldn't have a sense of the boundaries. Why can I hear air planes that are very far away from me but not hear what's going on in the next room very well?

I cannot see lotto numbers, I'm afraid... however, and this brings me to the next point, I can "see" people's superficial thoughts and one great way to demonstrate it is paper rock scissors.

I have done an experiment in which I played 100 games in a row with my wife, and wrote down the results. I can see which she'll throw, and I'll throw the opposite. I won 90% of the time (91 I think, but I didn't keep the paper I wrote it on). That's not really possible statistically.

You might wonder why I don't submit myself to public scrutiny if my results are so consistent. Frankly, I'm terrified of it. Anyone who cared to test me would be doing so in the spirit of "outing" me, with the attitude that I was a crackpot... I don't generally enjoy such circumstances.

If I did go forward in the interest of research, despite my personal reservations, then I know any mistake on my part would be magnified by the researchers and public to debunk me thanks to confirmation bias. In addition, I would expect to be faced with experiments devised in ignorance and so I'd be asked questions like "what are tomorrow's lotto numbers?"

Frankly, under those conditions, I will fail. I am not that good. It's a weaker sense that's easily overwhelmed by the normal senses and by emotions, and I'm not that good. I couldn't perform under pressure.

Even if I could, there would be very little upside: if I perform less than optimally, I'd be chided as an idiot or charlatan, and if I performed perfectly the experiments would be disregarded as flawed, and the subject matter silly. That's all without mentioning the possible damage to my reputation... there's not a lot of incentive.
