現代人智商一代不如一代？

Young people really ARE getting more stupid: IQs have started to fall by seven points per generation in pretty worrying trend, scientists discover

青年人的腦瓜越來越不好使了：科學家發現，他們的智商一代不如一代，每代人的智商都會下降7分，讓人們不得不警惕這其中的原因。

Young peoples IQ scores have started to deteriorate after climbing steadily since Wold War Two, a new study has found.

一份新的研究發現，在第二次世界大戰期間，人們智商一度呈穩定上升趨勢，而現今青年人的智商卻開始大幅下降。

The fall, which equates to about seven points per generation, is believed to have begun with those born in 1975, according to the first authoritative study of the phenomenon.

首份研究該現象的權威性報告稱，人們認為下滑趨勢最先出現在1975年出生的人身上，平均每個年代的智商減少約7分。

The drop in scores marks the end of a trend – known as the Flynn effect – which has seen average IQs rise for the past 60 to 70 years by roughly three points a decade.

智商分數的下滑現象讓弗林效應不復存在。在上世紀60-70年代，人們的智商每十年增加3分。

Scientists have described the results as impressive but pretty worrying, according to the Times.

科學家稱，這個結果十分可觀，而且發人深省。

The decline is do with a difference in technique in the way languages and maths are taught in schools, scientists have suggested.

科學家指出，這個下滑趨勢可能跟學校里教授語言和數學的技巧變化有關。

However, it could also be down to people spending more time on technological devices instead of reading books.

然後，這也有可能跟人們使用科技設備太多有關，因為他們閱讀的頻率大幅降低。

Stuart Ritchie, a psychologist at the University of Edinburgh who did not take part in the research, told the newspaper: This is the most convincing evidence yet of a reversal of the Flynn Effect.If you assume their model is correct, the results are impressive, and pretty worrying.

愛丁堡大學的心理學家斯圖爾特.里奇（Stuart Ritchie）並沒有參與這項研究，他在報紙上說：「這是證明弗林現象逆轉的有力證據。如果你也認為智商下滑的速度相當快，那麼這非常令人擔憂。」

However IQ scores might have fallen since the turn of the millennium, according to previous studies.

一份之前的研究指出，但是人們的智商是從千禧一代開始走下坡路的。

Two British studies suggested that the fall was between 2.5 and 4.3 points every ten years.

兩份英國研究指出，每隔十年人們的智商就會下降2.5-4.3分。

But due to limited research, their results were not widely accepted.

但是由於研究不夠充分，人們並不接受這些觀點。

In the latest study Ole Rogeburg and Bernt Bratsberg, of the Ragnar Frisch Centre for Economic Research in Oslo, found that Norwegian mens IQs are lower than the scores of their fathers when they were the same age.

奧斯陸Ragnar Frisch經濟研究中心的Ole Rogeburg和Bernt Bratsberg發現，挪威男人的智商比其父親同年的智商更低。

The pair analysed the scores from a standard IQ test of over 730,000 men – who reported for national service between 1970 and 2009.

他們還使用標準智商測試分析了73萬男人的智商，這次測試的時間是在受訪者1970-2009年服兵役期間。

The research has been published in the Proceedings of the National Academy of Sciences of the United States of America Journal (PNAS).

這次的研究被發表於《美國國家科學院院刊》。

The findings come after scientists revealed in December 2017 that regularly eating fish improves childrens intelligence as well as helping them to sleep better.

科學家曾在2017年12月透漏，經常攝入魚類食品能增進孩子的智力，同時能促進他們的睡眠。

They found that nine to 11-year-olds who eat it at least once a week scored almost 5 points higher in IQ tests to those who seldom do.

他們發現，每星期至少吃一次魚9-11歲的學齡兒童的智商高於不怎麼吃魚的兒童。

In this study by US researchers, more than 500 children were asked about how often they had consumed fish in the past month - with options ranging from never to at least once per week.

在美國研究學家的研究中，他們調查了500名兒童，他們讓受訪者根據無到每周一次的頻率就吃魚頻率給予評分。

They then took part in an IQ test which also considered such as verbal and written communication skills.

隨後受訪者參與了智商測試，這個測試考察的是他們的口頭和書面溝通等技巧。

After taking into consideration factors such as their parental education, occupation and marital status, it found children who eat fish least once a week score 4.8 points higher than those who never do.

家長的受教育水平，職業和婚姻狀況也成為了考察的對象，這個研究發現，那些每周吃魚一次的兒童比不吃魚的兒童要高4.8分。

Even those whose meals sometimes include fish scored 3.3 points higher.

那些吃魚兒童的智商都要明星高出三分。
