Running Head : PSYCHOLOGY OF soothsayingPSYCHOLOGY OF PREDICTIONIntuitive prognosticationAndJudgmental Heuristic-Representation[Author][Professor][University][Class]PSYCHOLOGY OF PREDICTION : INTUITIVE PREDICTION AND JUDGMENTAL HEURISTIC-REPRESENTATIONOver the decades , there has been much contr oversy on the potence of clinical predictions which argon mostly establish on experts erudition Researches from the aside decades have proven that statistical methods are more accurate than clinical predictions and other researches examined heuristic program rule principles used in predicting and judging outcomes during times when there is uncertainty or s undersurfacet(predicate) information Although relying upon these heuristics simplifies judgment to a certain degree , this whitethorn lead to severe errorsBasic all toldy , there are three heuristic principles proposed by Kahneman and Tversky (1974 . The first is called the availability heuristic , wherein predictions are make based on the information available . The second is anchoring , wherein predictions are based on a series of numerical estimates or anchors . The third matchless is called the representativeness heuristic , wherein predictions are made based on the subsistence of apparently similar cases . This studies one of these heuristic principles that is to say , representativeness heuristic , to show how this heuristic seat lead to stroke on clinical predictions and hence show that such heuristics are , indeed , less accurate than predictions based upon statistical methodsFirst , the pen feels compelled to give a little background on a few studies over the on-going clinical-statistical controversy . In 1996 Grove and Meehl proven that statistical method is almost invariably equal to or premium to clinical method (p . 293 ) in terms of truth in prediction . They analyzed secondary info glide slope from 136 published English researches since the 1920s which dealt with the prediction of health-related phenomena or valet de chambre behaviour . These researches should also contain at least one of each prediction - that is , at least one clinical prediction or one based on mankind judgment and at least one mechanical or statistical prediction .

As have mentioned earlier , all of the researches they included in their studied proved that statistical method is indeed almost always equal to or superior to clinical method because statistical prediction obtained from organized entropy are almost always free from bias . These data are observed from actual experiences and are recorded with hairsplitting instruments instead of relying on unaided memory . Moreover , statistical inferences are more objective than the human mind which can be bias at times or which can neglect certain important attributes that are necessary in front even concluding on the result and thus , sometimes resulting to severe errors in predictions Hence , predictions obtained from these statistical methods produce aboveboard results in contrast with predictions made from human judgmentThere are umteen reasons and examples that can 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 chosen due to the fact that it presents how people , specifically clinicians , taste certain events based on similar events that happened in the past . In the end , this shows...If you want to get a lavish essay, order it on our website: Orderessay
