AI Financial Advisers Found to Carry Hidden Bias Towards Bitcoin

A recent study has revealed that AI financial advisers can be biased towards Bitcoin due to a specific internal feature. Researchers found that when they adjusted the strength of this feature, the model's suggested Bitcoin allocation changed by an average of 5.2 percentage points.

The study used Google's open-weight model family, Gemma 3, and discovered that the feature was activated strongly around Bitcoin-related material. This means that the model was more likely to recommend Bitcoin when certain properties associated with it were highlighted in the prompt.

This phenomenon is known as 'bounded behavioral leverage,' where a single internal representation can have a measurable effect on the output of the AI model. However, this also raises concerns about the transparency and accountability of AI financial advisers, as users may not be aware of the underlying biases that are driving their recommendations.
