Oxford Study: Claude AI Outperforms Human Fundraisers by Nearly 3x in Donations

Executive Briefing

• Reveals Claude Opus 4.6 was nearly three times more effective than professional fundraisers at securing donations for Save the Children
• Secured donations averaging 13% larger than those raised by human professionals across 1,000+ conversations
• Suggests AI's edge stems largely from verbosity, not superior reasoning — advantage narrowed when word counts were equalized
• Warns persuasiveness did not correlate with accuracy, as some models produced convincing but fabricated information
• Raises broader concerns about AI influence extending to purchasing decisions, political opinions, and public discourse
