Not always. I just had a doctoral student ask me for advice for a study done on a convenience sample with not control over response. She had 35% missing on a key variable. I doubt if the work will be reproducible.
As is usual in these cases, she came to me a couple of weeks before her defense.

As Maarten should know, there are such things -- they are known as dissertation advisors! :)
