Judea Pearl: what Wikipedia removed
Judea Pearl is the computer scientist whose son, journalist Daniel Pearl, was kidnapped and murdered in Pakistan in 2002. The 2010 opening said he ‘is the father of journalist Daniel Pearl, who was kidnapped and murdered by militants in Pakistan in 2002.’ Today’s opening omits his son’s murder entirely, describing him only through his computer science career. A reader arriving today does not learn that Judea Pearl is the father of a journalist murdered by militants in Pakistan.
The word “militant” appeared 1 times in this article’s opening at its peak, in 2010. Today it appears nowhere in the article at all, references included. Checked against the full current article on 2026-08-01.

Counts are of the opening paragraph only, the part most readers, search engines and AI training sets ever quote.
What was taken out
Section titled “What was taken out”- The original opening line identifying him as a computer scientist and philosopher was rewritten into the current longer infobox-style introduction.

Computer scientist (born 1936) Judea Pearl ( Hebrew : יהודה פרל ; born September 4, 1936) is an Israeli-American computer scientist and philosopher , best known for championing the probabilistic approach to artificial intelligence and the development of Bayesian networks (see the article on belief propagation ). He is also credited for developing a theory of causal and counterfactual inference based on structural models (see article on causality ). In 2011, the Association for Computing Machinery (ACM) awarded Pearl with the Turing Award , the highest distinction in computer science, “for fundamental contributions to artificial intelligence through the development of a calculus for probabili…
