UnverifiedIn the ReAct framework, if the first reasoning step is biased, all subsequent steps will stack upon the erroneous premise, forming a "cognitive avalanche" effect — i.e., the risk of error accumulation.77% similarUnverifiedThe Plan-Act-Observe architecture inherently lacks pause points for human intervention, and once the initial instruction is imprecise, errors are progressively amplified through the loop.76% similarVerifiedWhen an autoregressive model produces an erroneous intermediate conclusion early in the reasoning chain, it causes subsequent steps to accumulate errors, forming an error accumulation effect.75% similarUnverifiedIn multi-step agent scenarios, a parameter error in an early step may only manifest as an erroneous outcome many steps later, and the cost of remediation is often far greater than the cost of prevention.73% similar
