A detailed study by researchers from Bonn and Frankfurt shows a large difference between how much people actually cooperate and how much they believe others will cooperate.

波昂與法蘭克福研究人員的一項詳細研究顯示，人們實際合作的程度與他們認為他人會合作的程度之間存在巨大差異。

The researchers studied a global group of over 100,000 people from 125 different countries. In the experiment, participants had to choose between two options: they could take a guaranteed $100 by not cooperating, or they could accept a lower payment of $70 if everyone cooperated. If the group cooperated, a total of $400 would be donated to fight climate change.

研究人員研究了一個由 125 個不同國家、超過 10 萬人組成的全球群體。在實驗中，參與者必須在兩個選項之間做出選擇：他們可以選擇不合作以獲取保證的 100 美元，或者在所有人合作的情況下，接受較低 70 美元的報酬。如果該群體選擇合作，總計 400 美元將被捐出以對抗氣候變遷。

The results showed that the actual global cooperation rate was 69%. However, people estimated that only 47% of others would cooperate, which shows a clear misunderstanding of social behavior. This gap was found in 124 of the 125 countries, suggesting that people worldwide tend to be too pessimistic about others.

結果顯示，全球實際的合作率為 69%。然而，人們估計僅有 47% 的他人會合作，這顯示出對社會行為有明顯的誤解。這種差距出現在 125 個國家中的 124 個，表明全世界的人都傾向於對他人過於悲觀。

In Germany, this difference was even more extreme. While 86% of German participants actually cooperated, they expected only 47.6% of others to do the same. Armin Falk from the University of Bonn emphasized that this pessimistic view can reduce a group's ability to work together. Furthermore, the research team asserted that putting the common good above personal interest is essential for solving major global problems.

在德國，這種差異更加極端。儘管 86% 的德國參與者實際上選擇了合作，但他們預期僅有 47.6% 的他人會這樣做。波昂大學的 Armin Falk 強調，這種悲觀觀點會降低群體共同工作的能力。此外，研究團隊斷言，將公共利益置於個人利益之上，對於解決重大全球問題至關重要。

The study concludes that humans are more likely to cooperate than we think, but this potential is limited by a widespread lack of trust in others.

研究結論指出，人類合作的可能性比我們想像中更高，但這種潛力被普遍缺乏對他人信任的問題所限制。
