Not that I know of... the closest might be the Broken Window Fallacy (http://www.investopedia.com/ask/answers/08/broken-window-fal...), where only the effect of "seen" outcomes are front of mind and considered, but "unseen" outcomes are ignored even if they are more impactful to reality.

While I agree with the others calling this a type of sampling bias, I've seen this type of error frequently enough that I think it deserves a more specific name.
