Magical Thinking

17 September 2016

How do you simultaneously cut taxes, increase spending, and balance the budget? All it takes is a little magical thinking – our topic for this week. Magical thinking happens when you have, say, firmly held beliefs based on scanty or even non-existent evidence or when you make plans in which ends and means are radically out of synch. Think of the belief that doing a certain dance can cause it to rain or that wearing a baseball cap inside out can lead to a rally. But, of course, magical thinking doesn’t show up just in outmoded superstitions or harmless rituals at sporting events. It is actually all around us. And it’s all around us despite the fact that we live in the most scientific age in all of human history. Science is the very antithesis of magical thinking. Indeed, you might think it’s the antidote to magical thinking. But for reasons not entirely obvious science has not stopped the spread of magical thinking. Magical thinking is everywhere. It infects politics, religion, the media, even the economy. And “infects” is, I think, the right word. We suffer from an epidemic of magical thinking. Just as opiate drugs ravage far too many families, so magical thinking ravages far too many minds. Magical thinking makes us ripe fro the picking by scam artists and demagogues. Witness our fascination with Trump’s wall, or countless fad diets, or the latest bargain basement gizmo that will do some supposedly amazing thing for three low cost payments of 19.99!

The question immediately arises of how there could possibly be such an epidemic of magical thinking in such a scientific age as ours. The easy answer is just that science is hard, while magical thinking is easy. And one should never be optimistic about the prospect of human beings pursuing the hard path rather than the easy path. Now you might think that pursuing the easy path is often a recipe for disaster. And no doubt it often is. But I suspect that our propensity for magical thinking may not be a matter of choice. It may be a matter of design. Our minds may have been designed by natural selection to engage in magical thinking.

想想大草原上的生命,我们物种最初进化的地方。潜在的掠食者到处潜伏,食物并不充足。我们的祖先没有时间研究科学。你听到草丛里有沙沙声,快决定,兔子还是狮子?现在你可能会认为最重要的是把它做好。如果有兔子,你应该相信有兔子。如果有狮子,你应该相信有狮子。毕竟,如果它是一只狮子,而你得出的结论是一只兔子,你可能会处于一个受伤的世界。

但这太简单了。相信真相通常是件好事——这一点毋庸置疑。但弄清真相需要时间和资源。如果这是一个确保你不被吃掉的问题,你可能没有时间或资源。此外,某些犯错的方式显然比其他方式更糟糕。如果它是一只兔子,而你直接得出结论,它是一只狮子,没什么大不了的。当然,你不能吃兔子,但至少你还活着。换句话说,当它是一只兔子的时候,错误地相信它是一只狮子可能是不好的——这会让你损失一顿饭——但当它是一只狮子的时候,相信它是一只兔子就更糟糕了。那会让你付出生命的代价。底线是,最好假设它是狮子,除非证明不是这样。 Truth be damned! Of course, you don’t want to starve to death. But hopefully sometimes you see the rabbit up close and personal. And then it’s alright to believe that it’s a rabbit. Sure, you’ll have lots of false beliefs. Sure, you’ll miss a few meals. But you’re very unlikely to become a meal yourself.

Now it seems to me that this kind of cognitive tendency is the very essence of magical thinking. Magical thinking isn’t about finding the truth. It’s about forming useful and firmly held beliefs -- even on the basis of scanty evidence. Science is about the opposite. It makes you slow down. It says consider all reasonable hypotheses and ferret out as much evidence as possible, before finally reaching a conclusion. The slow and laborious process of science wouldn’t have been much use to our forbears on the savannah. They faced the pressure of the moment. They needed quick and dirty ways of deciding what to believe and what to do.

And thus, I submit, was our propensity for magical thinking first born!

Of course, while magical thinking may have been useful on the Savannah, we’re not on the Savannah anymore. Away from the Savanah magical thinking can lead to disaster -- especially in environments filled with shysters, hucksters and demagogues, out to exploit our cognitive foibles for their own gain. Unfortunately, magical thinking is with us still. It has definitely not been driven out by science. Look no further than the media and our political debates. Indeed, our country’s leaders have themselves engaged in a quite a lot of magical thinking of their own over the years.

But of course, you, kind listener, are perhaps not taken in by the lure of magical thinking. So why not tune in this week and help us in our quest to combat its lure.

Another evolutionary

人类的另一种进化解释?美国人的魔幻思维就是所谓的自欺欺人的好处。在像我们这样的群居物种中,个体有时会利用欺骗来获得优势。然而,人们也进化出了辨别别人说谎的方法。因此,那些真正相信谎言的人?重讲可能比单纯的撒谎更成功。(显然,这里有很多空间来推测这对当前的总统候选人有什么影响!)如果富人,以及那些由富人资助的人,比如一些政客和那些所谓的智库人士,真的相信对富人征收尽可能低的税收可以带来尽可能高的经济增长这一神奇的想法,他们就会更成功地哄骗公众跟着他们走,从而以牺牲其他人的利益为代价让自己变得富有。
As I?m sure Ken Taylor knows, these evolutionary explanations are inherently speculative ? they have been justly stigmatized as ?evolutionary just-so stories,? like the Rudyard Kipling fables. We can?t go back and see directly how any of this supposedly evolved. However, if there is an inherited tendency for people to behave in these ways, there must evolutionary explanations for it, so why not go ahead and speculate!

Sorry to pop anyone's balloon

Sorry to pop anyone's balloon, but science is itself rife with 'magical' presumption and prejudice. The bias towards patterns inevitably leads to seeing them where they are not. Many abiding myths are sustained by this bias. Just try to explain to a gambling addict there is no such thing as a winning streak! But much of "science" is precisely seeing such patterns where there are none. But how then do we grasp the anomalous or random? Or even recognize them as such? Simply, by rigorously pursuing the "science" of the 'pattern' until there can be no doubt it does not exist. But what then? Have we learned anything? Absolutely! We have filled in the language of describing the otherwise indescribable. And language in this sense is more magical than science can ever explain or contribute to.

The above comment would be

如果上面的评论具体说明了一些所谓的假设和偏见,就会更有说服力。如果科学上充斥着这些假设和偏见,这应该很容易做到。也许一个人?S的偏见是另一个人吗?S价值观:科学当然是建立在假设和价值观的基础上的,比如节俭和预测,这些都是公开承认的。至于模式,是吗?这是一个很好的观点,人们可以认为他们?我们发现了一种根本不存在的模式,认识到这一点是科学方法的核心。对于理科生的方法论或统计学课程,有时一开始会给学生一页数字数据,并要求他们找出其中的规律。学生是吗?T最初告诉我们? are actually a page of numbers from a random number table. They quickly find patterns: ?Look, here are four 6?s in a row ? the probably of that happening by chance is only 1 in 10,000, so it?s obviously a significant pattern.? When they?re told that these are random numbers, they understand the issue: in scanning the page of numbers we?re unconsciously, or barely consciously, testing for thousands of possible patterns, so it isn?t surprising to find one that happened by chance. In science it?s fine to do an exploratory study to identify possible patterns, but then one needs to collect completely new data and specify in advance what is being tested for, e.g. finding an unusual number of 6?s at that exact point in the data. If that follow-up ?hypothesis testing? study finds it, then it?s likely a real pattern.
Of course science is done by people, and sometimes enthusiasm or ambition get in the way of best practice. Science is pretty good at dealing with this, through peer review and the replication of studies by different labs.

"Empirical" follies: Multiple

"Empirical" follies: Multiple universes, string theory.
"Formal" follies: The "law" of the excluded middle, the presumption of the "law" of contradiction that is formally valid only in reference to the quantifier. The use of the concept of infinity in the rationale for the calculus.
Photons get up to all sorts of bizarre antics. The description makes sense, but the explanation makes no damn sense at all. The behavior of a photon between air and glass, very weirdly, implies agency on its part, as if it were trying to stay within the law and break it too.

I'm not sure this is totally

我不确定这是否完全正确,但我还是要分享一下。On Saturday, September 17, 2016, I read the following in my local news rag, The Columbus Dispatch:

华盛顿——奥巴马政府已经同意向去年在巴基斯坦中央情报局无人机袭击中丧生的一名意大利援助人员的家人支付近300万美元,但还没有与一名在袭击中丧生的美国人达成和解官员说。”(emphasis mine)
那么,要多久才能与被杀的美国人达成和解呢?
(to give the Dispatch due respect, this story was authored by two reporters for The Washington Post.)
Magical thinking or simply wishful thinking?

A negotiation is not,

A negotiation is not, strictly speaking, a judicial process. And justice in America is not so swift as promised, in keeping with its contrary promise of due process. Italian law may make it easier to dicker, or maybe the litigants were simply more agreeable. But if anyone can find any reliable pattern in negotiation the knowledge would be valuable, and probably kept proprietary. I suppose, if we get really magical in our thinking, we could refer to The Art of the Deal.
Another common fallacy: "Once we have eliminated the impossible, whatever is left, however improbable, must be the truth." This is only valid where there is a comprehensive list of possibilities, each determinate in its characteristics and truth conditions. That is highly improbable!

Responding to the post about

回复那篇关于科学“愚蠢”的文章:是吗?对量子现象和解释(比如光子的作用)以及多重宇宙的想法持怀疑态度是合理的,如果它意味着“多重世界”?量子力学的解释。这些在科学上都没有定论。弦理论也是如此,即使在理论物理学家之间也存在争议。然而,是从什么地方发布的呢?不清楚到底是什么,假设和偏见?应该是在工作。一种不合理的假设或偏见是假设在质量和尺寸上比人类可以直接观察到的小20个数量级的现象一定会像我们这样宏观的物体?熟悉。量子力学课程开始时,教授会对学生说:“现在我?”我是这里唯一不知道的人吗?t understand quantum mechanics. By the end of the course, everyone here won?t understand it.? Hardly a situation where presumptions and prejudices are being imposed.
The rules of logic cited are in common use in everyday thinking and in other fields of human endeavor, although I realize more clarity is needed to specify under what conditions the rules should apply. (Thanks, philosophers, for working on this!). What ?the quantifier? means I?m not sure ? I know it can mean a part of speech in English grammar, but probably something different is intended here.
The complaint about ?the concept of infinity? in calculus seems very wide of the mark. In this context infinity is used in a situation where something has no definite upper limit. If we ask, ?is it bigger than X?? the answer is ?yes? no matter what definite number X is brought up. Math in general, not just calculus, would be very impoverished without this concept, and I can?t tell what the perceived problem with it could possibly be.

Magic and superstition are

魔法和迷信是近亲。然而,当人们坚定地相信其中一种或两种信仰时,奇怪的事情就会发生——比如医学上的安慰剂效应,或者东方苦行僧看似神奇的成就。有太多的事情是理性无法解释的——也永远无法解释。
