Why AI Chatbots Can't Process Persian Social Etiquette

3 weeks 3 days ago
An anonymous reader quotes a report from Ars Technica: If an Iranian taxi driver waves away your payment, saying, "Be my guest this time," accepting their offer would be a cultural disaster. They expect you to insist on paying -- probably three times -- before they'll take your money. This dance of refusal and counter-refusal, called taarof, governs countless daily interactions in Persian culture. And AI models are terrible at it. New research released earlier this month titled "We Politely Insist: Your LLM Must Learn the Persian Art of Taarof" shows that mainstream AI language models from OpenAI, Anthropic, and Meta fail to absorb these Persian social rituals, correctly navigating taarof situations only 34 to 42 percent of the time. Native Persian speakers, by contrast, get it right 82 percent of the time. This performance gap persists across large language models such as GPT-4o, Claude 3.5 Haiku, Llama 3, DeepSeek V3, and Dorna, a Persian-tuned variant of Llama 3. A study led by Nikta Gohari Sadr of Brock University, along with researchers from Emory University and other institutions, introduces "TAAROFBENCH," the first benchmark for measuring how well AI systems reproduce this intricate cultural practice. The researchers' findings show how recent AI models default to Western-style directness, completely missing the cultural cues that govern everyday interactions for millions of Persian speakers worldwide. "Cultural missteps in high-consequence settings can derail negotiations, damage relationships, and reinforce stereotypes," the researchers write. "Taarof, a core element of Persian etiquette, is a system of ritual politeness where what is said often differs from what is meant," the researchers write. "It takes the form of ritualized exchanges: offering repeatedly despite initial refusals, declining gifts while the giver insists, and deflecting compliments while the other party reaffirms them. This 'polite verbal wrestling' (Rafiee, 1991) involves a delicate dance of offer and refusal, insistence and resistance, which shapes everyday interactions in Iranian culture, creating implicit rules for how generosity, gratitude, and requests are expressed."

Vietnam Shuts Down Millions of Bank Accounts Over Biometric Rules

3 weeks 3 days ago
Longtime Slashdot reader schwit1 shares a report from ICO Bench: As of September 1, 2025, banks across Vietnam are closing accounts deemed inactive or non-compliant with new biometric rules. Authorities estimate that more than 86 million accounts out of roughly 200 million are at risk if users fail to update their identity verification. The State Bank of Vietnam has also introduced stricter thresholds for transactions: - Facial authentication is mandatory for online transfers above 10 million VND (about $379). - Cumulative daily transfers over 20 million VND ($758) also require biometric approval. The policy is part of the central bank's broader "cashless" strategy, aimed at combating fraud, identity theft, and deepfake-enabled scams. [...] While many Vietnamese citizens have updated their biometric data without issue, the measure has disproportionately affected foreign residents and expatriates who cannot easily return to local branches and dormant accounts that had been left inactive for years. schwit1 highlights a post on X from Bitcoin expert and TFTC.io founder Marty Bent: "If users don't comply by the 30th they'll lose their money. This is why we bitcoin."
