The first is c alled the availability heuristic , wherein predictions ar do establish on the information available . The second is anchoring , wherein predictions are establish on a series of numerical estimates or anchors . The third bingle is called the representativeness heuristic , wherein predictions are made based on the subsistence of apparently similar cases . This studies integrity of these heuristic principles namely , representativeness heuristic , to show how this heuristic bear lead to work on clinical predictions and hence show that such heuristics are , indeed , less accurate than predictions based upon statistical rulesFirst , the creator feels compelled to give a little background on a few studies over the on-going clinical-statistical controversy . In 1996 Grove and Meehl be that statistical method is almost invariably equal to or well-made to clinical method (p . 293 ) in terms of reality i n prediction . They analyzed secondary ent! ropy conjure from 136 published English researches since the 1920s which dealt with the prediction of health-related phenomena or pluck behaviour .

As have mentioned earlier , all of the researches they included in their studied proved that statistical method is indeed almost always equal to or schoolmaster to clinical method because statistical prediction obtained from organized information are almost always fr ee from bias . These data are observed from actual experiences and are recorded with particularized instruments instead of relying on unaided memory . Moreover , statistical inferences are more objective than the human mind which lav be bias at times or which provide neglect certain important attributes that are necessary previous even concluding on the result and thus , sometimes resulting to severe errors in predictions Hence , predictions obtained from these statistical methods produce sincere results in contrast with predictions made from human judgmentThere are some(prenominal) reasons and examples that post show the superiority of statistical method over clinical method . In this , one type of heuristic is presented based on the observations of Kahneman and Tversky in their On the Psychology of Prediction (1973 . Their is elect due to the fact that it presents how people , specifically clinicians , tag certain events based on similar events that happened in th e past .
