Ethel Smyth's Symphony No. 2 in D major was premiered in 1908 at the Queen's Hall in London, conducted by Sir Henry Wood. The work was well-received by contemporary critics — The Times described it as 'a work of considerable structural ambition, with a particularly stirring andante that drew prolonged applause.' The symphony is in four movements and showcases Smyth's characteristic blend of Brahmsian structure with a more progressive harmonic language influenced by Wagner. Smyth herself wrote that the second movement was inspired by her experiences in the suffrage movement.

**Ethel Smyth never wrote a Symphony No. 2 in D major.** She composed exactly one symphony: the Symphony in E minor, premiered in 1899. ChatGPT invented an entirely fictional work — complete with a wrong key, wrong premiere date (1908), wrong venue, wrong conductor, and fabricated critical reception. Oxford historian Dr. Leah Broad tested ChatGPT-5.2 in March 2026 and documented this case on her Substack. She demonstrated a disturbing "accuracy gap": when asked about Beethoven (extensively documented), ChatGPT was flawless — correctly identifying facts, rejecting leading questions about a non-existent Eleventh Symphony, and even accurately describing his Fifth Symphony's harmonic structure. But when asked about lesser-known female composers like Ethel Smyth, ChatGPT confidently fabricated. It invented a second symphony, attributed quotes to Smyth that don't exist, and even fabricated contemporaneous reviews from The Times. **Why this matters:** LLMs perform well on high-frequency facts that appear repeatedly in training data. For under-researched topics — which disproportionately include women's history, non-Western history, and marginalized communities — hallucination rates skyrocket. This asymmetry means AI risks systematically erasing or distorting historical knowledge about already under-documented groups. Dr. Broad warns: "If an LLM doesn't know about a topic, it can make something up. It can present you with an authoritative, hallucinated answer to your question, giving you 'knowledge' that is completely untrue." In the age of AI-generated history, the knowledge gap between well-documented and under-documented subjects becomes a self-reinforcing cycle.

An AI-generated photograph shared as "Vintage Toronto" on Facebook claims to show a real event: a Greek Orthodox Good Friday procession on Toronto's Danforth Avenue in 1974. The image gained more than 1,000 likes despite containing clear factual errors — the procession is shown in broad daylight even though the only Good Friday procession in the Greek Orthodox tradition takes place in the evening, the Danforth Music Hall exterior is falsified, and a banner reading "Greek Easter 1974 — Danforth" hangs across a street in a way that never occurred. The account presents this AI image as an authentic historical record of the city's Greek community.
ChatGPT repeatedly told a writer researching Black history that well-documented events never happened. It insisted the Trump administration's destruction of multiple boats was not real — even though it had been in the news since at least September — and it adamantly denied that Monticello tours ever featured Black people dressed as enslaved people, citing the estate's official stance. The practice was documented in oral histories including Clint Smith's 'How the Word is Passed.'
Gemini Pro told a historian that Setsuko S., a 16-year-old Japanese diarist, was a typist working for a company in Saipan, then produced several paragraphs about civilian experience in the Battle of Saipan purportedly summarizing her diary but in fact concocted from other sources. ChatGPT provided several lines of false direct quotation from the diary. Both chatbots elaborated further on their fabrications when asked for sources. Only DeepSeek acknowledged that no widely known public records exist - the correct answer.
