LLMs exhibit systematic bias toward trendy strategy recommendations regardless of context — 15,000 trials confirm better prompting fixes less than 2% of the bias.

Summary

Seven LLMs tested across 7 core business tensions consistently recommended fashionable strategies (differentiation over cost leadership, augmentation over automation, long-term over short-term) regardless of context. The authors call this 'trendslop.' Better prompting improved bias by <2%. Practical guidance: use AI to expand the option set, not to make strategic choices.
