QBists look at the future as a web of interlaced personal, numerical probability estimates, with no certainties anchored in REAL mechanisms. The probability that CERN will blow up the world is small enough to be negligible for most people, but not for all. The thing QBists reject as in principle unattainable is ABSOLUTE certainty, which many lay people and some physicists (Einstein was among them) continue to long for.<br clear="none"><br clear="none">Hans Christian von Baeyer<br clear="none"></div><br><div class="yqt1266781976" id="yqtfd06750">_______________________________________________<br clear="none">Fis mailing list<br clear="none"><a shape="rect" ymailto="mailto:Fis@listas.unizar.es" href="mailto:Fis@listas.unizar.es">Fis@listas.unizar.es</a><br clear="none"><a shape="rect" href="http://listas.unizar.es/cgi-bin/mailman/listinfo/fis" target="_blank">http://listas.unizar.es/cgi-bin/mailman/listinfo/fis</a><br clear="none"></div><br><br></div> </div> </div> </div></div></body></html>
