THE EYE DETECTOR
This is not a trick or a gimmick. It is a valuable tool that can be of great assistance in your everyday life. You can use it for entertainment purposes however.
Researchers have discovered that if you show people photographs of normal everyday items, the pupils of their eyes remain pretty much the same. When shown sexually oriented photos of the opposite sex, their pupils would dilate dramatically. Further research showed that whenever a volunteer was shown something that they wanted very much, the pupils would again dilate. Con-versely, when people are telling a blatant lie, the same thing happens.
You have to be watching very closely to see this happen, but a suddenly dilated pupil can tell you a lot.
How can you use this information? I hope explanation is not necessary as far as detecting lies go. You can of course use this for negotiations, making purchases, forming partnerships etc. While it can make you more careful and is valuable, nevertheless, this is not foolproof. You should not accuse anyone of lying unless you are positive. This is just a tool. It is not 100%. Use it as an indicator only.
It can also be handy in relationships. The next time you are flirting with someone, you might make mildly suggestive comments and study the eyes, watching for a sudden flare of the pupils. Again, be careful and tactful. You don't want to be sued for harassment.
For entertainment purposes, you might use something like the following. Pick a volunteer and seat them in front of you. Take four blank pieces of paper or cards and draw a big dollar sign on one of them and leave the other three blank, or write something benign on them like "pen," "pencil" and "paper clip." Tell your subject that the dollar sign represents one million dollars that you have just given them. Tell them to visualize the one thing in their life that they want more than anything. Something that they would be able to purchase with that million dollars. Make sure that they have something real in mind. Tell them to visualize the color, to really see it in their mind's eye. Picture it clearly.
Then you instruct them to pretend that the dollar sign represents the million and it will be theirs to buy their dream, unless. . . you can tell which card the dollar sign is written on.
Have someone else shuffle the cards or paper, mixing them up. When they are handed back to your subject, they should be concealed from you. If you are sitting at a table, your volunteer may simply hold them under the table out of your line of sight. If you are not at a table, use a towel or tray to obstruct your vision, hiding the cards from your sight. You MUST still be able to see your subject's eyes. Tell them to look at the cards one at a time and to then look at you before going on to the next one. You may have to ask them to look at one or two cards again. When they look up, you are of course studying their pupils. When they look up and you notice that their pupils are dilated, you know which card the dollar sign is on. You then amaze your audience by telling them that the dollar sign is on the third card they looked at (or whichever).
If there is light behind you or the room is somewhat bright, their pupils might become somewhat smaller. This is a telltale because it tells you that the pupils were larger. They will dilate again as the eyes adjust.
When they are looking at the blank or benign cards, there will be little or no change in the eyes. The card with the dollar sign will produce a much more noticeable response.
If you think that your subject is going to try and trick you, you might appoint a member of your audience to act as a sort of watchdog to see that your instructions are carried out. Or to watch for any cheating on either of your parts.
Practice this a few times with friends or family before trying it with an audience. People will think that you can read minds if this is done correctly.
I am not going to attempt to tell you all of the possibilities that this concept has. Law enforcement agencies, customs officers, lawyers, personnel officers etc. all have their own uses for this principle. If you just remember it and use it a few times, you will be amazed at the information this will give you. It can also give you quite a reputation.
Imagine the possibilities.
