and of course for IsMatch there is no difference in which direction you go, you can just stop at the first match and return true. in fact lookarounds aren’t necessary for IsMatch at all, they are indistinguishable from concatenation. a(?=b) is just ab for the purposes of IsMatch and a(?=.*b)(?=.*c) is just a(.*b_*&.*c_*) - the lookarounds only come into play when you want to know the position of the match, and what is around it. if you happen to use lookarounds in an IsMatch pattern today, consider RE# intersections a faster drop-in replacement with identical semantics.
We propose sycophancy leads to less discovery and overconfidence through a simple mechanism: When AI systems generate responses that tend toward agreement, they sample examples that coincide with users’ stated hypotheses rather than from the true distribution of possibilities. If users treat this biased sample as new evidence, each subsequent example increases confidence, even though the examples provide no new information about reality. Critically, this account requires no confirmation bias or motivated reasoning on the user’s part. A rational Bayesian reasoner will be misled if they assume the AI is sampling from the true distribution when it is not. This insight distinguishes our mechanism from the existing literature on humans’ tendency to seek confirming evidence; sycophantic AI can distort belief through its sampling strategy, independent of users’ bias. We formalize this mechanism and test it experimentally using a rule discovery task.
