A credence is more resilient the less it is expected to change given new evidence.

Suppose a person has two coins in front of them: coin A and coin B. They have flipped coin A thousands of times to confirm that it is unbiased, so it seems reasonable for the person to have a credence of 0.5 that if they flip coin A again, it will land heads. Coin B, on the other hand, might be biased or unbiased. However even if it is biased, the person has no evidence about which way it is biased, and so has no reason to think that the bias will favor either heads or tails. In these circumstances, it also seems reasonable for them to have a credence of 0.5 that if they flip coin B, it will land heads.

A person can have the same credence in two different propositions, and yet think that one of those credences is more likely to move given new evidence. For example, suppose that coin B lands on heads each of the first four times they test it. Based on these observations, their credence that coin B will land on heads on the next toss will be higher than 0.5, because they now have evidence that the coin is biased. However, if they saw coin A land heads four times in a row, their credence that the next toss will be a head will still be close to 0.5, because they already have considerable evidence that the coin is fair.

In choice situations where we have low-resilience credences, the value of information will usually be higher, because new evidence is more likely to change our credences.
