There’s actually a whole point about this in these Harry Potter analysis books I used to read obsessively. Two of their cardinal rules of HP foreshadowing are “Hermione is always right, except when she’s emotional” and “Ron is always wrong, except when he’s joking”. This actually plays out pretty frequently in the series if you look for it!
