這個(gè)片子最大缺點(diǎn)就是太散，總共有6個(gè)導(dǎo)演，5個(gè)制作團(tuán)隊(duì)來完成:
1. Intro & Transitional Segments (including Real Estate, Parenting, Cheating, Cause & Effect, Incentives) 1 director
2. A Roshanda by Any Other Name 1 director
3. Pure Corruption 1 director
4. It’s Not Always A Wonderful Life 1 director
5. Can you bribe a 9th grader to succeed? 2 directors

下面為主要內(nèi)容及觀感，有興趣的可以挑相應(yīng)電影片段來看：
0. Real Estate
Does real estate agent really represent your interest?
Incentives matter!!! If you can figure out what people’s incentives are, you have a good chance of guessing how they are going to behave.

1. Parenting (4’26’’-)
Levitt explains what he does in research: to figure out tricky ways to get a causality. There’s a difference between causality and correlation.

2. A Roshanda by Any Other Name
（莎翁名句：A rose by any other name would smell as sweet.）
（出自原書第六章）
Does name matter? Does name define your destiny?

Resume experiment: African American names vs. White names
View point: Name may not define your destiny but it can dictate the ways other ppl perceive you.

3. Cheating
(3&4出自原書第一章：教師和相撲運(yùn)動(dòng)員有何相似之處？)
Teachers could cheat.

4. Pure Corruption (24’20’’-47’48’’)
Corruption in the Sumo World with reference to Bernie Madoff (corruption in the realm of high finances)
        *誤譯：S.E.C (not S.C.C)
        很像犯罪紀(jì)實(shí)片，有點(diǎn)故弄玄虛之感。本可以獨(dú)立成片的題材，過短而語嫣不詳。日本文化對于西方觀眾/讀者本身具有神秘吸引力。也提到了日本和美國媒體的self-censorship，有一定自我批判的意味。

        Levitt: The only way to combat corruption is to change rules and undo corruption incentives, unleash more investigative reporters and to develop strong protections for whistle blowers.

5. Cause & Effect （47’49’’-49’10’’）
Does ice cream cause polio?

6. It’s Not Always a Wonderful Life (出自原書第四章)
Reasons why crime rates drop considerably in the 1990s?
觀感： 全片最有意思和最令人驚奇的發(fā)現(xiàn)。

6 most popular explanations (with authors’ verdict): More innovative policing (0%), harsher criminal policing (30%), changes in the crack market (15%), increase gun control, a strong economy, more police on the street (the last three about 10% in total).
(具體怎么得到這些數(shù)字的沒有解釋，這也許是有經(jīng)濟(jì)學(xué)家批評兩位作者是在描述計(jì)量經(jīng)濟(jì)學(xué)的原因，原書中是不是也沒有解釋？)

Almost half of the drop left unexplained. Levitt’s answer: Roe vs. Wade (the legalized abortion in 1970s)
Unwanted children were not born…
“Unintended consequence of legalized abortion”

關(guān)于這個(gè)結(jié)論的爭論（譯自維基百科）：
書出版之后Boston Fed的經(jīng)濟(jì)學(xué)家指出Levitt原論文中的統(tǒng)計(jì)錯(cuò)誤，改正這些錯(cuò)誤后不能得到墮胎合法化是犯罪率降低原因的結(jié)論。Levitt回應(yīng)，Boston Fed經(jīng)濟(jì)學(xué)家的改正由于存在嚴(yán)重的衰減偏誤（attenuation bias）也是有缺陷的，改正自己原文的錯(cuò)誤后，流產(chǎn)和犯罪之間的聯(lián)系較弱，但仍然統(tǒng)計(jì)顯著。Boston Fed的那兩位經(jīng)濟(jì)學(xué)家很快提供了反駁：即使使用Levitt建議的方法來分析數(shù)據(jù)，該數(shù)據(jù)不顯示流產(chǎn)率和犯罪率呈正相關(guān)關(guān)系。他們很快指出，這并不否定Levitt的論文，并強(qiáng)調(diào)由于該數(shù)據(jù)是如此混亂和不完整，很可能甚至是無法證明或反駁Levitt他們的結(jié)論。

7. Incentives
How Levitt failed to potty-train his daughter with her favorite M&M chocolates within three days.

8. Can a 9th grader be bribed to succeed?
Interesting (but costly) experiment again!

觀感：This is the most touching part of the movie and it sort of resonates with the segment on Parenting. But again the authors’ view on parents’ role in a child’s growth is ambiguous.
