Question
dr. haun developed a test that measures the amount of extrasensory perception (esp) individuals exhibit. the test is found to be reliable, which means that: this test is not measuring esp. this would be a good test to identify people with esp. despite what critics say, esp exists. this test measures something consistently but it may not be esp.
Reliability in testing refers to the consistency of a measure. A reliable test produces consistent results when administered repeatedly under the same conditions. However, reliability does not guarantee validity (that it measures what it is supposed to measure, in this case ESP). So a reliable test measures something consistently but that something may not be the intended construct (ESP here).
