Are most scientific results replicated?

"A small part of the solution, I believe, is to lower the barriers to publication of negative results so that more non-replications escape from the file drawer and see the light of day. It’s true that this could create an unmanageable burden of papers that need to be reviewed, but this can be avoided by moving some fraction of the scientific literature towards post-publication review. Another important step will be to make publishing one’s original data the norm. There are objections to these suggestions which I won’t go in to here, for now suffice it to say that I think that on balance, a more prolific science would lead us closer to truth."
