On the log\-odds line, credences range from to with the infinite extremes corresponding to probability and which can thereby be seen as "infinite credences"\. That's not to say that and probabilities should never be used\. For an ideal reasoner, the probability should be 1 \(where is the logical negation of \)\.3 Nevertheless, these infinite credences of 0 and 1 behave like 'special objects' with a qualitatively different behavior from the ordinary credence spectrum\. Statements like "After seeing a piece of strong evidence, my belief should never be exactly what it was previously" are false for extreme credences, just as statements like "subtracting 1 from a number produces a lower number" are false if you insist on regarding infinity as a number\.
"Extreme credences" here should likely be "infinite credences".
Even so, previous page made the exact counterpoint:
While strong evidence may not change your view of things, things, extreme evidence absolutely should make you revisit your estimate of even an infinite credence level.
