All of us believe what we see. W e say to ourselves，“I know，I was there; I saw it happened”and that seems to settle the matter. Or does it? Can we really trust the evidence of our eyes?
　　Take competitive sports for example. Fans who see the same game will not agree with each other and will the disagree with the referee（裁判）.“He was out of bounds when he caught the pass，”says one fan. Says another，“You are crazy. I saw it with my own eyes. He was five feet in bounds. You must be blind.” The referee rules that the receiver did step out of bounds. But thousands of fans are still disagreed —because they were there!

　　It s the same story in the courtroom. Trial procedure depends on witnesses giving sworn testimony（证词）.But just how reliable is the testimony of a person who reports what he has seen? In a recent study，ten thousand witnesses were asked to describe the thief they saw commit a crime. The study reveals that，on the average，the witnesses overestimated the man’s height by five inches，his age by eight years，and gave the wrong hair color in 83 percent of the cases. These witnesses didn’t play tricks on them!

　　What can we do to keep error to the least? First of all，don t let your emotions interfere with your vision. Don t see something because you want to see it. Secondly，try to stay relaxed. If you are tense，you are likely to see red when the color is blue. And finally，it helps to make notes of what you see. Don t rely on your memory alone. Take pictures，make recordings，and use any other aid to reduce distortion（歪曲）.

　　我们每个人都相信自己的眼睛。我们对自己说：“我知道的，我就在那里，我看到事情的发生”，而这似乎就解决问题了。真的解决了吗？我们真能信赖眼睛提供的证据吗？

　　以竞技体育为例，看同一场比赛的（球）迷们，各自意见相左，而且与裁判也会意见不一致。“他接到传球时，人已经出界了。”一个球迷说。另一个则说：“你疯了！我亲眼看见，他离边线还有五英尺。你一定眼睛瞎了。”裁判判定接球者的确已经踏出界，但仍有数千名球迷不服气——因为他们就在现场（亲眼看见了）！

　　在法庭上也是如此，审判的进程依程于目击者宣誓后所作的证词。但一个人报告他的亲眼所见时，其证词究竟有多可靠？在最近的一次研究中，一万名目击者被要求描述他们看见行窃的一个小偷。研究显示，目击者们平均高估了小偷的身高达五英寸，高估了小偷的年龄达八岁，83%的人说错了小偷的头发颜色。这些目击者并非故竟撒谎！

　　我们怎样做才能将误差降至最低？首先，不要让感情因素影响到你的观察力。不要因为你想要看到某物，才去看到某物。其次，尽量保持放松。如果你非常紧张，就可能把蓝色看成红色。最后，对你看到的事物做些笔记会有帮助，不要仅仅依赖自己的记忆。（你可以）拍些照片，进行录音，或使用其他方式，减少（对真实情况的）曲解。
