the publisher of "Skeptic" magazine.

懷疑論者雜誌的發行人。

We investigate claims of the paranormal, pseudo-science,

我們調查聲稱超自然偽科學的現象，

and fringe groups and cults and claims of all kinds between --

邊緣科學、邪教和種種主張 -

science and pseudo-science and non-science and junk science,

科學和偽科學和非科學和垃圾科學，

voodoo science, pathological science, bad science, non-science

巫毒科學、病態科學、壞科學、非科學，

and plain old nonsense.

以及無稽之談。

And unless you've been on Mars recently,

除非你最近去過火星，

you know there's a lot of that out there.

你知道世上有許多這些東西，

Some people call us debunkers, which is kind of a negative term.

所以，人人稱我們為拆穿者 雖然這稱呼有點負面。

But let's face it -- there's a lot of bunk,

但是，承認吧！確實有太多胡說八道了。

and we are like the bunko squads of the police departments out there, flushing out.

我們就像是警察局的詐騙小組進行掃除工作，

Well, we're sort of like the Ralph Naders of bad ideas

我們就像是偵辦壞主意的拉爾夫納德檢察官。

(Laughter)

(笑聲)

-- trying to replace bad ideas with good ideas.

嘗試將壞主意換成好的。

I'll show you an example of a bad idea.

讓我給你們看看壞主意長什麼樣子

I brought this with me.

我帶來了這個

This was given to us by NBC Dateline to test.

NBC晨間節目把這個給我們做測試

It's the -- it's produced by the Quadro Corporation of West Virginia.

由西維吉尼亞州的Quadro公司所製造，

It's called the Quadro 2000 Dowser Rod.

稱為Quadro2000探測棒。

(Laughter)

(笑聲)

This was being sold to high school administrators for 900 dollars a piece.

賣給高中職員 一個900塊美金

It's a piece of plastic with a Radio Shack antenna attached to it.

由一片塑膠連接RadioShack牌天線所組成。

You could dowse for all sorts of things, but this particular one

你可以用它探測任何東西 但是這一款，是特別為

was built to dowse for marijuana in students' lockers.

探測學生置物櫃裡的大麻所設計的。

(Laughter)

(笑聲)

So the way it works is, you go down the hallway and you see if

使用方法是你走進走廊一路偵測，看天線是否

it tilts toward a particular locker, and then you open the locker.

會指向某個置物櫃，然後，你就可以打開來檢查。

So it looks something like this.

所以，看起來就像這樣。

I'll show you.

我秀給你們看。

(Laughter)

(笑聲)

No, it -- well, it has kind of a right-leaning bias.

不，噢！它似乎會偏右邊。

So, I'll show -- well, this is science, so we'll do a controlled experiment.

所以，嗯！這是科學，所以我們來做個核對實驗。

It'll go this way for sure.

從這邊走應該就會朝向這邊了。

(Laughter)

(笑聲)

Sir, you want to empty your pockets. Please, sir?

先生，可以請您掏出您的口袋嗎？先生。

(Laughter)

(笑聲)

So the question was, can it actually find marijuana in students' lockers?

所以，問題是，這真的能找出學生置物櫃裡藏的大麻嗎？

And the answer is, if you open enough of them, yes.

答案是，如果你開得夠多，就找得出來。

(Laughter)

(笑聲)

(Applause)

(掌聲)

But in science, we have to keep track of the misses, not just the hits.

但是，在科學上我們必須記錄那些不準的，不能只記準的。

And that's probably the key lesson to my short talk here, is that

這也許就是我這簡短演講的重點，那就是

this is how psychics work, astrologers, and tarot card readers and so on.

這就是通靈者占星家、塔羅牌師等等的運作原理。

People remember the hits; they forget the misses.

人們會記住準的，忘記不準的。

In science we have to keep the whole database,

在科學上，我們必須保存完整的資料。

and look to see if the number of hits somehow stands out

檢視準確的數據是否會明顯地

from the total number that you would expect by chance.

從全部可預測的機率數字當中突顯出來。

In this case, we tested it.

在這個例子中，我們測試了這儀器。

We had two opaque boxes:

我們準備兩個不透光的箱子，

one with government-approved THC marijuana, and one with nothing.

一個藏有政府認證含有四氫大麻酚的大麻，另一個是空的，

And it got it 50 percent of the time --

準確度是一半一半，

which is exactly what you'd expect with a coin flip model.

跟你可預測的丟銅板的機率法則完全一樣。

So that's just a fun little example here of the sorts of things we do.

所以，這只是個有趣的小例子告訴你我們，工作的性質。

"Skeptic" is the quarterly publication.

懷疑論者雜誌是個季刊，

Each one has a particular theme, like this one is on the future of intelligence.

每季都有個主題，例如這一個是關於未來智慧的，

Are people getting smarter or dumber?

人是愈來愈聰明？還是愈來愈笨？

I have an opinion of this myself because of the business I'm in,

因為工作的關係，我自己對這有個人的見解。

but, in fact, people, it turns out, are getting smarter.

但事實上，結果顯示，人是愈來愈聰明的。

Three IQ points per 10 years, going up.

每十年提升3個IQ數值。

Sort of an interesting thing.

這點蠻有趣的。

With science, don't think of skepticism as a thing or even science as a thing.

講科學不能把懷疑論或甚至是科學當作一樣東西。

Are science and religion compatible?

像是在問科學和宗教可並立嗎？

It's like, are science and plumbing compatible?

像是在問科學與水電並立嗎？

These -- they're just two different things.

這些它們其實就是兩種不同的東西。

Science is not a thing. It's a verb.

科學不是東西，而是動詞，

It's a way of thinking about things.

是思考事物的方式。

It's a way of looking for natural explanations for all phenomena.

是為所有現象尋找自然的解釋的方法。

I mean, what's more likely:

我的意思是，

that extraterrestrial intelligences or multi-dimensional beings travel across

外星生物和多重次元的生靈橫跨

the vast distances of interstellar space to leave a crop circle

星際空間浩瀚的距離，留下麥田圈，

in Farmer Bob's field in Puckerbrush, Kansas to promote skeptic.com, our webpage?

在堪薩斯州帕克布萊西的鮑伯農場上，宣傳我們的網站skeptic.com的可能性較大，

Or is it more likely that a reader of "Skeptic" did this with Photoshop?

還是某懷疑論者雜誌的讀者利用Photoshop製作出來的可能性大呢？

And in all cases we have to ask

在所有這些案例裡頭，我們都必須問，

(Laughter)

(笑聲)

-- what's the more likely explanation?

最有可能的解釋是什麼？

And before we say something is out of this world,

在我們說有些東西來自外世界之前，

we should first make sure that it's not in this world.

我們首先應該查明它並不存在於這個世界。

What's more likely --

哪個可能性較高，

that Arnold had a little extraterrestrial help in his run for the governorship?

阿諾史瓦辛格有外星人幫忙競選州長呢？

Or that the "World Weekly News" makes stuff up?

或是世界新聞周刊捏造的呢？

(Laughter)

(笑聲)

And part of that -- the same theme is expressed nicely

其中同樣的主題，卻在辛尼海羅斯的卡通中，

here in this Sidney Harris cartoon.

被詮釋得很不錯。

For those of you in the back, it says here: "Then a miracle occurs.

給坐在後排的觀眾，這上面說，"然後奇蹟發生，

I think you need to be more explicit here in step two."

我覺得你應該把第二步驟說得更詳細一點。"

This single slide completely dismantles the intelligent design arguments.

這一張投影片完全拆散了智慧設計論證。

There's nothing more to it than that.

再清楚也不過了。

(Applause)

(掌聲)

You can say a miracle occurs.

你可以說奇蹟發生。

It's just that it doesn't explain anything.

只是這不能解釋任何事情。

It doesn't offer anything. There's nothing to test.

不能提供什麼。沒有東西可以測試。

It's the end of the conversation for intelligent design creationists.

這是智慧設計創意工作者的談話終點。

Whereas -- and it's true, scientists sometimes throw terms out as

反之，確實科學家有時會丟出一些名詞當作

linguistic place fillers -- dark energy or dark matter or something like that --

語言學的填空詞--黑暗能量或黑暗物質或其他類似的等等。

until we figure out what it is, we'll just call it this --

直到我們明白這是什麼之前，我們就暫時稱它為這個，

it's the beginning of the causal chain for science.

對科學而言這是因果連結鏈的開始。

For intelligent design creationists, it's the end of the chain.

對智慧設計創意工作者而言，則是因果連結鏈的末端。

So again, we can ask this: what's more likely?

我們可以再次詢問，哪個可能性較高，

Are UFOs alien spaceships or perceptual cognitive mistakes -- or even fakes?

幽浮比較可能是外星人的太空船或是感官認知的錯誤或甚至是假的。

This is a UFO shot from my house in Altadena, California,

這是我從加州猶它旦市家中拍到的幽浮照片，

looking down over Pasadena.

向下俯瞰帕薩迪納市。

And if it looks a lot like a Buick hubcap, it's because it is.

如果這看起來像別克汽車的輪蓋，那是因為它根本就是。

You don't even need Photoshop; you don't need high-tech equipment;

你甚至不需要Photoshop，不需要高科技器材，

you don't need computers.

你不需要電腦，

This was shot with a throwaway Kodak Instamatic camera.

這是用柯達Instamatic拋棄型相機拍的。

You just have somebody off on the side with a hubcap ready to go.

你只需要有人在旁邊準備擲出輪蓋就可以了。

Camera's ready -- that's it.

相機準備好--就這麼簡單。

(Laughter)

(笑聲)

So, although it's possible that most of these things are fake

雖然，大部份這些東西都有可能是假的，

or illusions or so on and that some of them are real,

或是幻象等等，但有些是真的。

it's more likely that all of them are fake, like the crop circles.

更有可能全部都是假的，就像麥田圈一樣。

On a more serious note, in all of science we're looking for a balance

說正經的，在所有科學裡，我們都在尋找一種平衡，

between data and theory.

介於數據與理論之間。

In the case of Galileo, he had two problems

以伽利略來說，他有兩個困難，

when he turned his telescope to Saturn.

當他用望遠鏡觀察土星時，

First of all, there was no theory of planetary rings.

首先，那時沒有行星環的理論，

And second of all, his data was grainy and fuzzy,

第二，他的數據是粗糙模糊的，

and he couldn't quite make out what it was he was looking at.

而且，他並不太了解自己正在看的是什麼，

So he wrote that he had seen --

所以他就寫下他看到了。

"I have observed that the furthest planet has three bodies."

"我觀察到最遠的星球有三個形體"。

And this is what he ended up concluding that he saw.

而這是他最後對自己的觀察所做的結論。

So without a theory of planetary rings and with only grainy data,

沒有行星環的理論且憑靠粗糙的資料，

you can't have a good theory.

你不可能建構很好的理論。

And it wasn't solved until 1655.

一直到1655年才得到解答，

This is Christiaan Huygens's book in which he cataloged all the mistakes

惠更斯的書中記載了所有人在嘗試了解，

that people made in trying to figure out what was going on with Saturn.

土星時所犯的錯誤。

It wasn't till -- Huygens had two things.

但是一直到惠更斯有了兩樣東西，

He had a good theory of planetary rings and how the solar system operated.

好的行星環理論和了解太陽系如何運轉。

And then, he had better telescopic, more fine-grain data

而且，當時他有更好的望遠鏡及更細微的數據，

in which he could figure out that as the Earth is going around faster --

從中他了解到當地球轉得比土星更快速，

according to Kepler's Laws -- than Saturn, then we catch up with it.

根據克卜勒三大定律，然後我們會追上它。

And we see the angles of the rings at different angles, there.

我們從不同的角度，看見行星環不同的角度。

And that, in fact, turns out to be true.

而事實上，結果真是如此。

The problems with having a theory

有理論的問題是，

is that your theory may be loaded with cognitive biases.

你的理論可能會充滿認知偏見。

So one of the problems of explaining why people believe weird things

所以，要解釋人為何會相信奇異現象的困難之一，

is that we have things on a simple level.

就是我們會簡化事物。

And then I'll go to more serious ones.

然後，我之後會再說比較多的例子。

Like, we have a tendency to see faces.

例如，我們會傾向看見臉孔，

This is the face on Mars, which was --

這些是在火星上的臉，

in 1976, where there was a whole movement to get NASA

1976年有很多運動要求美國太空總署

to photograph that area because people thought

為這些地區拍攝照片，因為人們認為

this was monumental architecture made by Martians.

這些是火星人蓋的紀念建築。

Well, it turns out -- here's the close-up of it from 2001.

後來發現這是2001年所拍攝的近照。

If you squint, you can still see the face.

如果你斜視仍可以看見臉，

And when you're squinting, what you're doing is

當你斜視時，你就是在

you're turning that from fine-grain to coarse-grain.

將影像從微粒變成粗粒的。

And so, you're reducing the quality of your data.

也就是說你在降低資料的品質。

And if I didn't tell you what to look for, you'd still see the face,

如果我不告訴你，該看什麼，你還是會看見臉孔，

because we're programmed by evolution to see faces.

因為進化將我們設計成，會看見臉孔的生物。

Faces are important for us socially.

在社交上，臉孔對我們很重要，

And, of course, happy faces.

當然還有笑臉，

Faces of all kinds are easy to see.

各種臉孔都很容易被看見。

(Laughter)

(笑聲)

You can see the happy face on Mars, there.

你可以看見火星上的笑臉在上面。

If astronomers were frogs perhaps they'd see Kermit the Frog.

如果天文學家是青蛙的話，那麼他們可能就會看見芝麻街的青蛙柯密特。

Do you see him there?

看見了嗎？

Little froggy legs.

小小的青蛙腳。

Or if geologists were elephants?

或是如果考古學家是大象呢？

Religious iconography.

宗教肖像。

(Laughter)

(笑聲)

Discovered by a Tennessee baker in 1996.

1996年由田納西的一位麵包師傅所發現，

He charged five bucks a head to come see the nun bun

他收一個人頭五塊錢來讓人看這塊修女麵包，

till he got a cease-and-desist from Mother Teresa's lawyer.

直到他收到特瑞莎修女的律師寄來的禁止通知函為止。

Here's Our Lady of Guadalupe and Our Lady of Watsonville, just down the street,

這是在下一條街的瓜達露珮聖母和華森維爾聖母。

or is it up the street from here?

或是從這裡過去的上一條街？

Tree bark is particularly good because it's nice and grainy, branchy,

樹皮的效果特別好，因為粗糙且枝繁，

black-and-white splotchy and you can get the pattern-seeking --

黑白有汙點，然後你就可以尋找圖樣，

humans are pattern-seeking animals.

人類是圖樣找尋的動物。

Here's the Virgin Mary on the side of a glass window in Sao Paulo.

這是在聖保羅一個玻璃窗邊上的聖母瑪利亞。

Now, here's the Virgin Mary made her appearance on a cheese sandwich --

而這是聖母瑪利亞顯靈在起司三明治上，

which I got to actually hold in a Las Vegas casino,

實際上我在拉斯維加斯賭場親手拿過。

of course, this being America.

當然因為這裡是美國。

(Laughter)

(笑聲)

This casino paid 28,500 dollars on eBay for the cheese sandwich.

這間賭場在eBay上花了28500美金買下這起司三明治。

(Laughter)

(笑聲)

But who does it really look like, the Virgin Mary?

但是這到底看起來像誰呢？聖母瑪利亞嗎？

(Laughter)

(笑聲)

It has that sort of puckered lips, 1940s-era look.

有那種40年代噘嘴的樣子，

Virgin Mary in Clearwater, Florida.

聖母瑪利亞在佛羅里達州的清水市。

I actually went to see this one.

我實際去看過這個。

There was a lot of people there -- the faithful come to be in their --

那裡聚集了許多人--虔誠的信徒來到這裡，

wheelchairs and crutches, and so on.

有坐輪椅的、有撐拐的等等，

And we went down, investigated.

我們到那裡去做了調查。

Just to give you a size -- that's Dawkins, me and The Amazing Randi,

順便讓你知道，我們的人力，那是道金斯、我和令人驚奇的瑞迪。

next to this two, two and a half story size image.

在兩個兩個半層樓高的影像旁邊，

All these candles, so many thousands of candles people had lit in tribute to this.

所有的蠟燭人們，點燃成千上萬的蠟燭來讚頌這景象。

So we walked around the backside, just to see what was going on here,

所以我們就繞到背後去看看，這到底是怎麼回事。

where -- it turns out wherever there's a sprinkler head and a palm tree,

結果發現只要有灑水噴頭和棕櫚樹的地方，

you get the effect.

你就會看到這樣的效果。

Here's the Virgin Mary on the backside, which they started to wipe off.

這就是在後面，他們已經開始在擦拭的聖母瑪利亞。

I guess you can only have one miracle per building.

我想一棟建築物頂多只能有一個奇蹟吧！

(Laughter)

(笑聲)

So is it really a miracle of Mary, or is it a miracle of Marge?

這到底是聖母瑪利亞的奇蹟？還是瑪姬的奇蹟？

(Laughter)

(笑聲)

And then I'm going to finish up with another example of this

接下來我想要以另一個類似的例子來作為結束，

with audio -- auditory illusions.

用聽--聽覺幻象。

There is this film, "White Noise,"

有部電影叫鬼訊號，

with Michael Keaton about the dead talking back to us.

由麥可基頓主演，關於亡者回應我們的話。

By the way, this whole business of talking to the dead, it's not that big a deal.

順便說一下，跟亡者說話並沒有什麼了不起，

Anybody can do it, turns out.

結論是任何人都做得到。

It's getting the dead to talk back that's the really hard part.

叫亡者回應我們的話，才是真正難的地方。

(Laughter)

(笑聲)

In this case, supposedly, these messages are hidden in electronic phenomena.

這個例子，在電子現象當中藏有一些訊息，

There's a ReverseSpeech.com web page from which I downloaded this stuff.

我從ReverseSpeech.com的網站上下載了這個，

Here is the forward -- this is the most famous one of all of these.

這是向前轉的，也是最有名的一段。

Here's the forward version of the very famous song. (Music)

這是這首非常有名的歌曲的正常版本。

Boy, couldn't you just listen to that all day?

天啊！這音樂可以讓人聽一整天。

(Laughter)

(笑聲)

All right, here it is backwards,

好的，接下來是倒轉的版本。

and see if you can hear the hidden messages that are supposedly in there. (Music)

看看你是否聽得出裡面應該藏有的訊息。

What did you get?

你聽到了什麼？

Audience: "Satan."

(聽眾：撒旦)

Michael Shermer: "Satan?" OK, well, at least we got "Satan."

麥可‧薛莫：撒旦，好，至少我們聽出了撒旦。

Now, I'll prime your auditory part of your brain

現在我將先替你頭腦的聽力部分做準備，

to tell you what you're supposed to hear, and then hear it again. (Music)

告訴你，應該聽見的內容然後再聽一遍。

(Laughter)

(笑聲)

(Applause)

(掌聲)

You can't miss it when I tell you what's there.

我告訴你那裡有什麼之後，你就不可能會錯過。

(Laughter)

(笑聲)

All right, I'm going to just end with a positive, nice, little story

好，最後我將以一個正面溫馨的小故事做為結束。

about -- the Skeptics is a nonprofit educational organization.

關於懷疑論者協會是非營利的教育組織。

We're always looking for little, good things that people do.

我們總是在尋找人們所做的小小的好事。

And in England, there's a pop singer.

在英國有個流行歌手，

Very -- one of the top popular singers in England today, Katie Melua.

是當下英國最頂尖的流行歌手凱特瑪露。

And she wrote a beautiful song.

她寫了一首很美的歌。

It was in the top five in 2005, called, "Nine Million Bicycles in Beijing."

2005年排名前五名歌名，叫做"北京有九百萬輛腳踏車"。

It's a love story -- she's sort of the Norah Jones of the U.K. --

描寫一個愛情故事--她就像是英國的諾拉瓊絲。

about how she much loves her guy,

關於她有多愛她的男人，

and compared to nine million bicycles, and so forth.

與九百萬輛腳踏車做比較等等。

And she has this one passage here.

其中有一段歌詞
