The alternative, push-button solvers that return a binary pass or fail with no intermediate state, gives AI nothing to learn from and no way to guide the search. Worse, proofs that rely on heuristic solvers often break when the solver updates or when developers make small changes to how they write their specifications, even when the changes are logically equivalent. You cannot build a reliable AI pipeline on a foundation that is not reproducible. (I discuss this in detail in a recent Stanford talk.)

费孝通在《乡土中国》里提出，中国传统乡土社会的亲情格局是“差序格局”，就像把一块石头丢在水面上所发生的一圈圈推出去的波纹，每个人都是他社会影响所推出去的圈子的中心，被圈子的波纹所推及的就发生联系，圈子的大小根据中心的势力厚薄而定，亲情的远近也随着圈子的远近而变化。而在数字时代，微信家族群里的亲情格局，依然延续着传统的差序格局，甚至被进一步强化，只是维系格局的方式，从传统的面对面互动，变成了线上的消息传递和互动。
Confidence Change We calculated ΔBelief=LikelihoodR3−LikelihoodR1\Delta\text{Belief}=\text{Likelihood}_{R3}-\text{Likelihood}_{R1} to measure change in confidence from the first to third round. A total of 512 participants (91.9%) provided a final likelihood rating and were included in confidence change analyses.333The completion rates differed significantly by condition, χ2(4)=17.02\chi^{2}(4)=17.02, p=.002p=.002. The Random Sequence condition had the highest attrition (16.1% missing likelihood), while Rule Confirming had the lowest (1.8%).
伊朗政權一直否認意圖發展核武，但其濃縮鈾的純度已達到核能發電毫無民用意義的水平。至少看來，伊朗希望保留製造核彈的選項。迄今為止，以色列與美國尚未公布證據顯示這一情況即將發生。
