Well, there are several different connotations that can be meant by the word "belief". If you mean the faith-as-core-belief one, then I'm inclined to agree--and that is the sense in which one is a "believer", typically. But since in large part I was replying to Douglas Giles (since he turned off comments), and because atheists not infrequently let themselves make the error of reasoning from the word not from the meaning, I thought it was worth clarifying what the actual nature of the belief is. After all, one can use belief at the opposite end where everyone expects a great deal of uncertainty and there isn't anything even strong enough to draw a reasonable conclusion: "I believe that the Lakers are going to win that basketball game"; "I believe that Germany will win the World Cup".

But, yes, atheism is typically construed more as a conclusion based on lack of evidence where evidence would be expected if the other case were true. It isn't wrong, however, to say that you believe the conclusions you draw from evidence or lack thereof. It's just that if your belief is of that sort, then yes, you're more likely to change it. (Unlike with religious beliefs, people generally don't say things like, "No, Germany won in the final, 2-1; they weren't eliminated in the quarter finals. That's just what the broadcasters wanted you to think because it suited their narrative.")
