A rational belief isn’t necessarily correct or true. Rational beliefs are justified, in that they logically follow from premises that are accepted as true. In the case of probabilistic statements, a rational strategy is one that maximizes the chance of being correct or otherwise reaching a defined goal state. It doesn’t have to work or be correct in any ultimate sense to be rational.
If I play the lottery and win, playing the lottery turned out to be a way to get lots of money. It doesn’t mean that playing the lottery was a rational strategy. If I make a reasonable investment and improbable misfortune strikes, losing the money, that doesn’t mean that the investment wasn’t rational.
This has no bearing on the point above. In essence you’re just rephrasing Robin’s definition, “better believing what is true, given one’s limited info and analysis resources.” The disposition best-calculated to lead to true beliefs will not produce true beliefs in every instance, because true beliefs will not always be justified by available evidence.
