AI personas in shared context yield diminishing returns, study finds

By PulseAugur Editorial · [1 sources] ·

A new analysis suggests that using multiple AI personas within a shared context window offers diminishing returns, as their reasoning becomes correlated. The study proposes that at 60% shared context, five expert personas are only as effective as 1.47 independent ones, and this benefit plateaus significantly as more personas are added. The research highlights that correlated biases do not average out, meaning a thousand flawed personas will still produce a flawed result, and the choice of aggregation method (mean vs. median) impacts how confidently wrong answers are handled.
