First, as a scientist, your study must be reviewed by your peers. The study is sent out to independent reviewers before it reaches that the next stage--a review by the state or national academy of science. The paper is then published in the appropriate journals. That opens the door for someone attempt replication of your research. Errors are not helpful to one's career. Fraud is doom when caught. Remember cold fusion? it was killed by failure of subsequent efforts to replicate the results, thus ending the careers of those who published the first results.
