The experimenters use GPS, little orange flags, and a specified destination as the three ways of telling how good they are at walking in a straight line while blindfolded.

I thought with all your survival training, youd love this storyHello? Jamie? .Oh, hes gone.”Its a deceptively simple concept that has puzzled serious s
14、cientists for 100 years. Supposedly, when blindfolded, its impossible for humans to travel, whether on foot, in water, or by road, in a straight line. Its a challenge Adam and Jamie just cant resist.,Transcript,Part I Communicative Practice II. Gap-filling,Adam: “Come on. Come on back in here. Did y
15、ou even hear a word that I said?” Jamie:“Yeah. Humans cant move in a straight line while blindfolded.” Adam: “Thats the story. How do you want to test it?” Jamie: “Well, when I think about moving in a straight line, I think about walking.” Adam: “I think you might be right. Is that where you want to
16、 begin?” Jamie: “Yeah. All we need is a couple blindfolds and a big wide-open field.” Adam: “Lets do it.”,Transcript,Part I Communicative Practice II. Gap-filling,A big field you say?

21、in 3, 2, 1, go!” All he has to do is walk in a straight line with his eyes closed. How hard can it be?,Transcript,Part I Communicative Practice II. Gap-filling,Adam: “It is a very weird thing to be walking without any visual or auditory stimulus.” Whats really weird is, apparently, how surprisingly
22、difficult it is. Adam: “Youre holding a picture of it in your head, and in your minds eye, youre walking a nice straight trajectory across that landscape. Tickling at the back of your mind, youre thinking something might be wrong, but try as you might, you feel like youre walking straight.,Transcrip

Nothing to
24、ld me that I was possibly walking in a 200-foot-diameter circle. I am totally amazed by that result.”A result nailed by the GPS trail. The astonishing disparity between Adams perception and his actual route is there for all to see.,Transcript,Part I Communicative Practice II. Gap-filling,Adam: “That
25、 is hilarious.” Its a result that begs several questions. The first of which is, will Jamie do any better? Adam: “Jamies blind-man walking in 3, 2, 1, go!” With all the confidence and certainty youd expect from the Hyneman (Jamies family name), he strides off towards the target tree.before veering o
26、ff course like hes got a short right leg. And any doubt that subtle topographical features were the reason Adam went left are dispelled as Jamie leans so far to the right, he turns back on himself in a corkscrew pattern.

Gap-filling,Adam: “Test two, I didnt walk straight, and I didnt even walk straight in the
29、 same way I didnt walk straight the first time. I went in a circle in the other direction.” Yeah, two things are clear from Adams second test. His route is far from straight, and theres no discernible pattern to his meandering.Jamie: “Bye.”Adam: “Bye.”A theory compounded on Jamies second test becaus
30、e once again, he immediately heads off in the wrong direction.,Transcript,Part I Communicative Practice II. Gap-filling,Jamie: “Im lost. Trying to walk in a straight line while being blindfolded is an exercise in futility because without any cues like vision or sounds and so on, youre relying on pur

Gap-filling,Jamie: “But youre fluid. Youre not like a machine. You can kind of meander and wander, and, in fact, thats kind of what these
32、 GPS paths are showing, is this looks like a meandering stream.”And that meandering corkscrewing leads Jamie and Adam straight to a firm conclusion.Adam: “Stop. We came here to look at the myth that a person who is blindfolded cannot walk in a straight line, and we have definitely proven that with t
