Inside the secret reason an iPhone may refuse to autocomplete certain political words

A hidden keyboard list

Independent researcher Derik Kauffman says he found a concealed collection of words and phrases in Apple’s iOS keyboard. The keyboard usually avoids suggesting listed terms through autocomplete or swipe-typing, though users can still enter them manually.

Kauffman estimates the collection at roughly 100,000 entries, excluding Chinese characters. Apple has not confirmed its size or composition, and another researcher, Matt Suiche, said he independently recovered the list and found a near-perfect match with Kauffman’s findings.

Political terms across languages

Kauffman says most flagged entries involve vulgarity, drugs, sex or violence, but some are politically sensitive. Examples include “dictator Trump,” “sleepy Joe,” “Tibetan independence” and “United Ireland.” The list varies by language, according to Kauffman. He said Hindi swipe-typing blocks phrases aimed at Narendra Modi and Rahul Gandhi, while French and Hebrew examples include “immigration too high” and “occupied territories.”

Testing shows uneven results

Reuters tested a small sample of the phrases and found them difficult to swipe-type or absent from autocomplete. “United Ireland” sometimes became “United Iceland,” while “Sleepy Joe” could produce “Sleepy hope.” The filtering does not appear consistent in every case. Kauffman said “read smut” worked, but “read gay smut” did not; he described the system as “a very light-touch form of censorship.”

Apple and critics respond

Apple did not address the list’s reported size, contents or political terms. It said the keyboard is designed to avoid inappropriate or offensive suggestions, and users can type specific words and override predictive text.

David Greene of the Electronic Frontier Foundation said he could see value in limiting unwanted suggestions, but argued users should be informed and offered customization. Kauffman said Apple’s choices matter because hundreds of millions of people use iPhones.
