Toxic Truth: How Wikipedia Poisons Global Knowledge

How the world’s most trusted encyclopedia became a vector for bias, erasure, and AI misinformation and disinformation

Today, Wikipedia celebrates its 25th anniversary. What began as a promising vision for shared knowledge and a free internet encyclopedia has devolved into a battlefield. Today, interest groups orchestrate disinformation and chaos, erasing narratives, deleting documented historical evidence, and even distorting facts in the exact sciences.

Why does this matter in 2026? Beyond its average of 3.5–4 billion monthly visits (according to SimilarWeb) and its dominance as the top Google result for countless terms, Wikipedia is a primary training source for LLMs like ChatGPT, Gemini, and others.

In practice, this means that when fake news is injected by anonymous users who have accumulated enough permissions, it flows directly into AI engines. This cycle perpetuates lies until they effectively erase reality.

Israel and the Jewish people are primary targets of this phenomenon, as extensive disinformation surrounding the Gaza war and the systematic deletion of documented Jewish history have been orchestrated by organized interest groups within Wikipedia (follow Wiki Bias for more info) but they are not alone. Women, Hindus, the people of Iran protesting against their regime, and many other groups are deeply affected by this systemic bias.

For those who have been following me over the past year and a half, you know my team and I, along with other individuals and organizations, have been extremely active on this front, while also raising public awareness.

Recently, Jimmy Wales, the founder of Wikipedia, who isn’t identified as pro-Israel at all, stated that the entry titled “Gaza genocide” was locked due to an immense bias against Israel and failure to meet Wikipedia’s standards. Moreover, editors who attempt to provide a more balanced perspective are sometimes subjected to votes to revoke their editing privileges.

But it doesn’t end there - The city of Jerusalem, the capital of the State of Israel and where all residents hold Israeli residency or citizenship, is not defined as being located in any specific country on Wikipedia.

Instead, it is categorized under “Southern Levant.”

Despite efforts to correct its location to Israel, including a personal intervention by Wikipedia co-founder Jimmy Wales (!), the definition was reverted to its former state.

Another example, from this past week alone, is Nas Daily.

He is a content creator with billions of views, a successful tech company, and over 70 million followers. Because he is an Arab Muslim and an Israeli citizen who promotes coexistence rather than anti-Israel sentiment, his Wikipedia entry has been completely distorted. References to his Arab identity were erased to undermine him, and his entire body of work is framed as “pro-Israel activity”, a gross misrepresentation that ignores the vast majority of his non-political, technology-driven business.

Furthermore, Israel is the only country in the world with a dedicated entry comparing its national institutions to those of the Third Reich, alongside extensive content comparing the Zionist movement to the Nazi movement.

Zionism is the movement supporting the Jewish people’s right to live as a free and self-determining nation in their ancestral homeland, the Land of Israel, where they have maintained a continuous presence for over 3,000 years. For many years now, there have been ongoing efforts to distort its true meaning by falsely portraying it as a form of racism or colonialism. Wikipedia takes that to the next level.

Any attempt to rectify these distortions is almost futile; the entries are reverted instantly by a faction of hostile editors with permissions.

Moreover, editors who try to balance the picture are sometimes subjected to a vote to revoke their editing privileges. Therefore, the solution lies in a fundamental policy shift, a change in public perception to recognize Wikipedia as an unreliable source that must be overhauled, and pressure on AI companies to train their models and source their content from alternative platforms, such as Grokpedia (I have zero interest in promoting it, and if it will turn out to be like Wikipedia in the future, I’ll call them out too).

Your support on social media is vital. Also stopping your donations to Wikipedia helps in promoting change as they are more urged to make it a better place.

Furthermore, my team and I have built an AI engine that does not rely on poisoned sources like Wikipedia or Reddit. It is currently in Beta, and we would love your feedback, kindly visit BrightMind AI.

If you’d like, you can support my work here, (thank you for that).
