(ISNS) -- Scientists analyzing how magicians

Penn & Teller perform one of the oldest

known illusions now reveal that some

aspects of the magic trick are even more

effective at manipulating audiences than the

magicians predicted.

These findings not only shed light on basic

In recent years, neuroscientists have

increasingly been analyzing magicians' performances to gain insights on the human

Macknik, director of the laboratory of behavioral neurobiology at the Barrow

Neurological Institute in Phoenix, Ariz. "So we've been poaching their techniques,

bringing them back to the labs to increase our rate of discovery."

The latest magic trick Macknik and his colleagues investigated is the classic cups and

Magicians can make the balls seemingly jump from cup to cup, disappear from one cup

and appear in another, turn into other items and so on. (The modern swindler's

version is the shell game.)

To learn more about this illusion, the researchers enlisted the aid of the famous duo

Penn & Teller. Seven volunteers watched 10-12-second-long video clips of Teller

performing the illusion in front of a NOVA scienceNOW TV crew at the duo's theater

in Las Vegas.

The balls in the illusion are typically brightly colored, while the cups are usually

opaque. Penn & Teller practice a version with three opaque and then three

transparent cups.

"It's a great act, and the trick still works even with transparent cups, because they're

just that good — people still can't follow all the movements and see how the trick is

done," Macknik said.

"I've seen them do this trick for more than 20 years," said vision scientist Flip Phillips

at Skidmore College, in Saratoga Springs, N.Y. "The best part of the whole routine is

that, despite the fact that they are telling you what they are doing — they're showing

you what they're doing — you're still amazed because you just can't fight the

deception."

Teller devised this variation while fiddling with an empty water glass and wadded-up

paper napkins for balls at a Midwestern diner. He turned the glass upside down and

put a paper ball on top, then tilted the glass so that the ball fell into his other hand.

The falling ball was so compelling that it drew his own attention away from his other

hand, which was deftly and secretly loading a second ball under the glass. Teller found

that the sleight happened so quickly he himself did not realize he had loaded the cup.

He surmised he missed it because the falling ball captured his attention.

In the experiments, the volunteers reported when they saw balls get removed from,

or placed under, cups by pressing buttons. The researchers also used cameras pointed

at the eyes of the volunteers to track their gazes.

The researchers found that while the falling ball did draw audience attention, other

aspects of the trick were actually stronger at making the illusion work. For instance,

audiences were fooled more often when the magician attempted to drop a ball that

was stuck to a cup.

"A lot of times the intuitions we have about the way things work aren't the way things

work," said Phillips, who did not take part in this research. "This isn't to put down

Teller — Teller's intuition is good. There is research we did on a famous sleight of hand

known as the French drop where Teller's intuition on how to sell the trick is perfectly

correct."

I don't find anything surprising about this article. Social cues

are a tool but they essentially are a subset of misdirection.

I'm also unsurprised by the commentor who immediately used

this article to push their personal political agenda, as if any

other political party is different. Talk about classic

misdirection.

No, the real magic is how people who are clearly brain dead

give the illusion of speech.

It would indeed be interesting to study con artists, and

whether politicians have learned from their tricks. So I'm with

littleredtop; and commenters yammering "troll" are just part

of the illusion.

Sorry, no, this is about physical manipulation of objects to

entertain a willing audience. Seizing the comment section and

twisting the thesis of the article to justify preaching and

hyperbole is trolling.

It would be nice if these words were linked to this clip having

been posted somewhere, such as YouTube.
