A simple experiment suggests a way to encourage truthfulness
一个简单的实验却为我们提供了一种鼓励诚实的途径

IS SIN original?
人性本恶？

That is the question addressed by Shaul Shalvi, a psychologist at the University of Amsterdam, in a paper just published in Psychological Science.
这是由阿姆斯特丹大学的一位心理学家-Shaul Shalvi，在《心理科学》杂志上发表的一篇论文中所提出的问题。

Dr Shalvi and his colleagues, Ori Eldar and Yoella Bereby-Meyer of Ben-Gurion University in Israel, wanted to know if the impulse to cheat is something that grows or diminishes when the potential cheater has time for reflection on his actions.
Shalvi博士和他的两位同事-以色列Ben-Gurion大学的Ori Eldar 和 Yoella Bereby-Meyer，希望知道如果那些潜在的骗子有时间对他们的行为作出充分考虑，他们撒谎的冲动会否因此增强或减弱呢？

Is cheating, in other words, instinctive or calculating?
换句话说，撒谎究竟是人的一种本能行为，还是经过仔细分析后所作出的选择呢？

Appropriately, the researchers apparatus for their experiment was that icon of sinful activity, the gambling die.
研究人员为他们的实验选择了一样合适的工具—骰子—罪恶活动的标志。

They wanted to find out whether people were more likely to lie about the result of a die roll when asked that result immediately, or when given time to think.
他们想查明的是：人们是在摇骰后立即被询问其结果时容易撒谎呢，还是在他们获得一定的思考余地的时候呢？

To carry out their experiment, Dr Shalvi, Dr Eldar and Dr Bereby-Meyer gave each of 76 volunteers a six-sided die and a cup.
实验前，Shalvi博士，Eldar博士和Bereby-Meyer博士给作为实验对象的76位志愿者每人发了一个摇盅和一粒骰子。

Participants were told that a number of them, chosen at random, would earn ten shekels for each pip of the numeral they rolled on the die.
参加者被告知他们中的一部分被随机抽选出来的，会依据其掷出的骰子点数而得到相应数目的奖励，每点10谢克尔。

They were then instructed to shake their cups, check the outcome of the rolled die and remember this roll.
接着他们便按照指示摇盅，开盅查看结果，记住点数。

Next, they were asked to roll the die two more times, to satisfy themselves that it was not loaded, and, that done, to enter the result of the first roll on a computer terminal.
然后他们被要求多摇两次，以让自己确信骰子中没有被灌铅。最后，让他们自己在电脑终端里输入第一次所掷出的点数。

Half of the participants were told to complete this procedure within 20 seconds while the others were given no time limit.
有一半参加者被要求在20秒内完成整个实验流程，而另一半则没有时间限制。

The researchers had no way of knowing what numbers participants actually rolled, of course.
研究人员当然无法知晓每个参加者实际掷出点数。

But they knew, statistically, that the average roll, if people reported honestly, should have been 3.5.
但他们知道，依照统计学规律，如果所有人都能做到如实上报点数，那么这次实验的平均掷出点数应为3.5。

This gave them a baseline from which to calculate participants honesty.
这就为研究人员提供了一个测量参加者诚实程度的依据。

Those forced to enter their results within 20 seconds, the researchers found, reported a mean roll of 4.6.
他们发现，那组被要求于20秒内输入结果的的参加者所上报的掷出点数平均值为4.6，

Those who were not under any time pressure reported a mean roll of 3.9.
而另外没有时间压力的参加者的为3.9。

Both groups lied, then.
显然这两组人都撒谎了，

But those who had had more time for reflection lied less.
不过在那些有充分时间进行考虑的参加者中撒谎的较少。

A second experiment confirmed this result.
第二次实验则验证了这一结果。

A different bunch of volunteers were asked to roll the die just once.
这次是另一群不同的志愿者被要求掷骰子，不过只掷一次。

Again, half were put under time pressure and, since there were no additional rolls to make, the restriction was changed from 20 seconds to eight.
同上次一样，他们中一半人被限制了时间，并且由于此次只需掷一次骰子，时间限制也从20s缩短为8s。

The others were allowed to consider the matter for as long as they wished.
其余一般则想考虑多久都行。

In this case the first half reported an average roll of 4.4.
在这次实验中，前面有时间限制的一半人所上报点数的平均值为4.4，

Those given no time limit reported an average of 3.4.
而没有时间限制的所上报的平均值为3.4。

The second lot, in other words, actually told the truth.
换言之，后者如实上报了数据。

The conclusion, therefore, at least in the matter of cheating at dice, is that sin is indeed original.
因此，得出的结论是-至少在此次摇骰作弊的案例中如此—人性本恶。

Without time for reflection, people will default to the mode labelled cheat.
在缺少时间进行考虑的情况下，人们会进入默认的撒谎模式。

Given such time, however, they will often do the right thing.
然而，如果他们获得了那样的考虑时间，一般会作出道德上正确的选择。

If you want someone to be honest, then, do not press him too hard for an immediate decision.
所以，如果你希望某人对你诚实，那么千万别逼迫他立即做出出决定啊。
