I Can Read Your Mind. I know what you are thinking before you even know

Way to ruin it for everyone jerk.

Nah, I learned this trick in my Differential Equations class. I love that class, boring at times but you learn alot of cool stuff in it.

I didn't even apply real math to it until I figured it out.

I suppose if I wanted to get more mathematical without jumping around:

You are really being asked to pick two one-digit numbers, x and y. to take those numbers to get the two digit number of that, take 10x + y = z

then they want you to subtract x and y from z, z-x-y=w. substitute 10x + y for z and you get 10x + y - x - y = w. y cancels and you're left with 9x = w. hooray, I solved it without any non-algebraic means.

Had a friend tell me that when he was in college, some class (psychology?) sent their students out to conduct a survey.

To take the survey, they showed the subject a card which read "Pick a number between 1 and 4".

After waiting a while, they'd turn the card over, and the other side read "Why did you pick 3"?

The significance of the experiment is that when you ask a sample of people to pick a number between 1 and 4, people will tend to avoid the extremes (thus tending not to pick 1 or 4), and will tend to pick a number that's "above average". Supposedly, if you ask a large sample to pick a number between 1 and 4, somewhat over 3/4th of them will pick 3.

That's why C was for a long time the multiple choice answer that had the greatest statistical chance of being correct. Testing companies have been aware of that trend for a while now, and I'm not sure it's still true.

And hence, one of the things "psychics" and "fortune-tellers" use to trick...er, read your mind! Yeah, that's it!
