Right/Wrong selection decision matter a lot to the organisations.

Consider, for a moment that any selection decision can result in 4 possible outcomes. A decision is correct when an applicant was predicted to be successful and proved to be successful on the job, or when the applicant was predicted to be unsuccessful and would perform accordingly if hired. In the first case, we have successfully accepted; in the second case we have successfully rejected. Problems arise when errors are made in rejecting candidates who would have performed successfully on the job (reject errors) or accepting those who ultimately perform poorly (accept errors). Don't you think, these problems can be significant and can result in costly mistakes?
