major forms of reliability are internal consistency‚ test-retest‚ inter-rater‚ and intra-rater. These four types of reliability offer some sort of way to achieve standardization of scores of data. In staffing a company you may want to look at the test-retest model. The weakness of this method is obvious as depending on the time it takes to test the second time the variable being measured may have actually changed. This would be related to an informal interview including questions about the job and

The reliability of human memory‚ though typically seen as quite accurate and trust-worthy‚ has been questioned by researchers in recent decades. In particular‚ one area of memory that has raised questioning is emotional memories that are extraordinarily vivid and detailed‚ which were first referred to as ‘flashbulb memories’ in 1977 by Roger Brown and James Kulik‚ which occur due to powerful events such as the death of Princess Diana‚ and the terrorist attacks on 9/11. These memories are not as reliable
