Always wise to be ready to adjust first impressions. But more often than not they are in fact accurate.

But it's more complicated than that, because there is more than one way to adjust. I remember an interview on the radio once about Irish music sessions, where the man being interviewed said more or less 'When I first heard it I thought - "This is all the same tune, I don't like it. And then I got to hear more of it, and I thought "No, it's all different tunes". And then I got to hear it more and play it and I decided "Yes - it is really all the same tune - I love it." '

I can think of relationships like that. The adjustment that makes the difference isn't always in our understanding of what other people are like, it can be in how we estimate that way of being.

Jane Austen's Price and Prejudice was of course originally called "First Impressions".
