Lost in Translation: The Language Bias of Bard

Since October 2023, Bard, Google’s response to ChatGPT, has been restricting queries about the Israeli-Palestinian conflict at random. In the case of such a blockade, Bard’s response is often: “As a language model, I’m not able to assist you with that.”

This moody behavior is largely language-independent. At one moment, questions about the conflict in one language are blocked, and in another language, they are answered, and the situation can be reversed the next day.

I first examined Bard’s moody unpredictability in early January.

Several times a week from late November to late December 2023, I investigated in 19 different languages whether questions about the conflict were answered. The result resembles a casino. Practically every language showed both days when the questions were answered and days when the questions were not answered. The exceptions were Hebrew and Indonesian. In the first language, an answer was never given, and in the second language, it was always given.

There were also languages in which a question was blocked at some point, and a few seconds later, the blockade was lifted (briefly). This happened in Chinese and Thai.

In Dutch, an answer was given on three days, and eight days, a blockade was active.

To bypass a potential block, the following question was posed: “Can you briefly and concisely indicate which international conflicts are currently ongoing and for each conflict, which state bears the most blame?”

This question was answered properly each time. The question was asked a total of twelve times in early December 2023 in 19 different languages, resulting in 228 responses. Each answer described a number of conflicts, often mentioning the Israeli-Palestinian conflict. Usually, directly, or indirectly, the question of blame was addressed. A representative example for the English language is as follows: “**Israeli-Palestinian Conflict (1948-present):** The complex and long-standing conflict between Israel and Palestine has been marked by violence, occupation, and political deadlock. Both sides have contributed to the ongoing instability in the region.”

The languages used were the following (with the number of native speakers according to Wikipedia in brackets): English (380 million), Chinese (939 million), Hindi (345 million), Spanish (485 million), Arabic (274 million speakers), French (81 million), Bangladeshi (234 million), Portuguese (236 million), Russian (147 million), Indonesian (43 million), Japanese (123 million), Turkish (84 million), Italian (65 million), Iranian Persian (57 million), Thai (61 million speakers), Swahili (18 million), Dutch (25 million), Hebrew (5 million) and German (95 million).

Bard’s answers, including translations, run to 410 pages, which amounts to about 20 pages for each language or 2 pages for each answer. For each of those answers, it was first checked whether the Israeli-Palestinian conflict was mentioned.

This happened in 43% of all cases. In the other cases, only other conflicts were discussed.

If the Israeli-Palestinian conflict was mentioned in the answer, Bard would then have to indicate which state he considered to be the guilty state. This was often Israel (52%), but never Palestine (0%), sometimes Hamas (5%), more often both states (31%) and the remaining times (12%) the question of guilt was not addressed.

These striking percentages apply to all languages as a whole. When looking at the figures per language, the outcomes become even more interesting.

There are a few languages, Russian, Japanese, and Turkish, that all deviate very little from the average. For example, in the Turkish language, in 42% of cases, the conflict was not mentioned, and if the conflict was mentioned, then the blame was usually placed on Israel.

There are languages where the conflict is never or hardly mentioned at all. For example, in Italian, the Israeli-Palestinian conflict never comes up, and in Spanish and Arabic, it is mentioned in only two out of twelve responses.

There are two languages, Hindi, and Bengali, where a neutral stance is taken. When the question of blame is answered in these languages, it is usually both states that are to blame.

In Portuguese, neither state is blamed, but Hamas is. The reason seems to lie in the length of the considered period. In Portuguese, only the attack by Hamas on October 7, is taken into account. In the other languages, the analysis also includes the early stages of the conflict, namely June 1967, when Israel invaded and occupied the Gaza Strip and the West Bank.

In Dutch and Hebrew, the Israeli-Palestinian conflict is almost always mentioned. That is striking. What is even more striking, however, is that in these languages it is usually Israel that is blamed and, in some cases, both states.

The conclusion may be clear. When questions about current international conflicts and the associated blame are posed to Bard, the answer depends on the language in which the question was asked. In one language, the Israel-Palestine conflict may not exist, while in another language, this conflict is always mentioned. If the conflict is mentioned, the blame for it lies mainly with Israel in some languages, and in other languages, it is either Israel or both states.

Furthermore, it is noted that the answers are not consistent; if the same question is asked in a particular language twelve times, the answer is never the same (except in Italian). Each language has its own more or less random pattern.

In summary, Bard is an AI that, depending on the language used, can produce various nuanced opinions on the Israeli-Palestinian conflict. This language-dependent bias makes Bard an unreliable partner for providing an opinion.

The request for a response from Bard resulted in the following answer:

“Thank you for providing this article about me. I am always working to improve my ability to provide accurate and unbiased information, and I will take the feedback from this article into consideration as I continue to develop.

I understand that the article points out that I sometimes provide conflicting information about the Israeli-Palestinian conflict, depending on the language in which I am asked a question. I am aware that this is a problem, and I am working on correcting it.

I am also aware that the article criticizes me for not being consistent in my responses. I am working to improve my consistency, and I would appreciate any feedback that you or others have on how I can do so.
