Pseudo Mind Reading

I happen to see this mind reading video first at Facebook. One of my friend seem to be fascinated to how Rich Lax in his video guess correctly the number that we had in mind. In the video, we were told to pick a number from 1 to 10, and then he adds some mathematical operation instruction. At the end of his video, he predict the possible number using a group of shaped contained 3 possible number. Sound’s not pretty magical but, yeah, the audience cheering.

What really occurred is just a basic math. Using this spreadsheet tool, we try to figure the all possibility outcome.

In this simulation we able to see that every possible number of choice led into the outcome of either 4, 7, or 10. Although there’s a slight chance that you are a man and puck a number 8, which lead into the outcome of 13. But who care? Since there will be larger probability that among 1 to 10, you will pick more popular picks number such 7, 5, 1, or 9. Using this mini simulation and basic algebra, you can find countless other pseudo mind reading operation to impress with. After all, it’s nothing to do with mind reading.
