想知道政坛人士什么时候是在隐瞒坏消息吗？这里有个小窍门。

　　A study of body language has found leaders tend to signal good news by pointing with their dominant hand – but gesture gloomy tidings with their weaker hand.

　　一项有关身体语言的研究发现，政治领袖在传达好消息时往往喜欢用惯用手来做手势——但在传达不好的讯息时则往往喜欢用那只不常用的手。

　　It means a right-handed politician， such as Nick Clegg， will wave his right hand when passing on positive news， while a left-hander – such as David Cameron – will gesture with his left.

　　这说明爱用右手的政客，比如尼克·克莱格，在传达好消息时会用右手，而和大卫·卡梅隆一样的“左撇子”在这种情况下则会用左手。

　　The Dutch researchers say the discovery does not just help voters tell if their politicians are trying to disguise their meaning.

　　开展该研究的荷兰研究人员称，这一发现不仅仅能帮助选民判断他们的领袖是否在试图掩饰自己的真实本意。

　　They say the difference in the way left and right-handed leaders gesture could also explain the unlikely number of left-handers in office.

　　惯用左手和惯用右手的领袖在手势习惯方面的差别还能解释为什么现任的很多领袖都是“左撇子”。

　　Five out of six of the most recent presidents of America have been southpaws， far exceeding chance， they said.

　　在美国最近六届总统中，有五位是左撇子，远超过了正常概率。

　　Dr Daniel Casasanto of the Max Planck Institute for Psycholinguistics said： ‘Since the dawn of the television era， we have had many， many more left-handers in presidential office than we should expect according to their prevalence in the population.

　　马克斯 普兰克语言心理研究院的丹尼尔 克萨恩托博士说：“自从人类进入电视时代后，出现了很多‘左撇子’领袖，其概率远远超过左撇子在人口中的比率。”
