characters Judgment under Uncertainty Heuristics and Biases ↠ eBook, PDF or Kindle ePUB Ging covariation and control overconfidence multistage inference social perception medical diagnosis risk perception and methods for correcting and improving judgments under uncertainty About half of the chapters are edited versions of classic articles; the remaining chapters are newly written for. We usually think of bias in the context of underlying motivations or interests particularly in the political realm The underlying premise of this book is that there are much fundamental biases in human judgments Humans aren t perfectly logical creatures Even when we have perfectly good information and we are free from motivational biases we still make poor decisionsI picked up this book after there was a few passing references to it in Harry Potter and the Methods of Rationality In this alternate world Harry Potter is supposed to represent the paragon of Baconian rationalism and he uses the fact that he has read Kahnemann s work as evidence of his rationalityThe book itself isn t for the faint of heart it is a collection of scientific articles published by psychologists with research interests in the science of judgment The topic matter itself is interesting If you were interested in the material I would recommend reading the introductions and conclusions of each essay and if it captured your interest enough you could read further into the experimental sections I got less thorough in my reading as I got through the book because I was anxious to be done I already read enough scientific papers as a graduate student I don t want to read The material itself is fascinating I believe the editor Kahneman has written another book directed towards a lay audience Thinking Fast and Slow I will look into reading that too but I m sure a lot of the material in it is drawn from these scientific studiesI think the material itself would be good for most readers to be aware to recognize the limitations and tendencies of human thought Here are a few examplesHumans tend to be uncharitable in making judgments of others when seeking explanations of others behavior we tend to attribute to characteristics of the individual and not the situation in which they find themselves For instance if a student is doing bad in school we are likely to think they are lazy rather than to consider the circumstances going on in their homeHumans tend to be very bad predictors of outcomes that have multiple steps For instance when trying to predict how long a project will take to complete we very easily underestimate the time reuired Why Each step of the process reuires successful completion and so a single fudge factor doesn t account for all the delayHumans rarely take into account base case statistics For instance if an editor is very confident a manuscript will get published because of the excellent writing he rarely takes into account the success rates of similar books The integration of book base case data AND intuitive judgments is referred to as regression and leads to better estimatesDefinitely a good read but I just wasn t in the mood for scientific papersHere s a list of the essays contained in the book and a brief description of eachJudgment under uncertainty heuristics and biasesMore of a summary of the entire book with introductory concepts including representativeness eg what is the probability that object A belongs to class B misconceptions of chance truly random events don t seem random to humans and sample size humans are bad at taking into account the effects of sample size when making decisionsBelief in the law of small numbersThe believer in the law of small numbers gambles his hypotheses on small sample sizes without realizing that the odds against him are unreasonably high Bad for scientists who only do 5 6 replicates in a studySubjective probability A judgment of representativenessHuman evaluate the representativeness of a sample by looking for similarities to the population of interest and the apparent randomness of the sampleOn the psychology of predictionPredictions have three sources of information 1 prior general knowledge eg base rates 2 information specific to the case at hand and 3 information on the reliability of the information you have been given Humans generally ignore 3 entirely and generally rely entirely on 2Studies of representativenessWhen seeking to attribute causes to effects the lay person has three sources of information distinctiveness information how does this situation differ from others consistency information does this happen in repeated experiments and consensus information does everyone respond this way Humans generally ignore consensus informationJudgments of and by representativenessPopular induction Information is not necessarily informativeCausal schemas in judgments under uncertaintyIt is a psychological commonplace that people strive to achieve a coherent interpretation of the events that surround them and that the organization of events by schemas of cause effect relations serve to achieve this goalShortcomings in the attribution process On the originsThis chapter examines non motivational attribution biases biases that aren t due to self serving motives For example the fundamental attribution error in which we infer broad personal dispositions and expect consistency in behavior or outcomes across widely disparate situations and contextsEvidential impact of base ratesEven when given base rate data humans rarely take it into account using their initial intuitions rather than the hard numbers provided by scientific studiesAvailability A heuristic for judging freuency and probabilityIntroduce a new heuristic availability Humans estimate probabilities by how easily information is retrieved from memory For instance if I asked you to compare the word count of words that start with r and words that have r in the third position you would have an easier time recalling words that being with r and likely overestimate the word count compared to the latterEgocentric biases in availability and attributionThis looks at how the ego plays a role in availability For instance I tend to focus on my inputs into the project rather than my teammates and am likely to overestimate my contribution This can result in tensions such as who gets authorship on a paperThe availability bias in social perception and interactionThe simulation heuristicThere are two kinds of judgments where availability can play a role how easily past information is recalled and how easily new situations are created using the imagination The latter is called the simulation heuristic For instance if I asked to to think up all the ways you could kill someone with a paper clip you would start to get an idea of availabilityInformal covariation assessment Data based versus theory based judgmentsHumans are really bad at evaluating covariation because they look at a limited selection of the data For instance when evaluating the uestion does God answer prayers you have to take into account a the time you prayed and your prayer was answered b the times you prayed and the prayer wasn t answered c the times you didn t pray and you still got positive results and d the times you didn t pray and you got negative results Hard to evaluate rightThe illusion of controlIn situations where the actor has absolutely no control eg rolling dice doesn t stop the actor from behaving as if he has some control over the situation resulting in all sorts of odd behaviorsTest results are what you think they areThis was one of my favorites and is basically what it says In many instances psychologists interpret what they want to see The authors look at the example of how Rorschach blot tests were used to evaluate whether patients were homosexual or notProbabilistic reasoning in clinical medicine Problems and opportunitiesOftentimes physicians don t have proper training in probability and aren t using diagnostic tests appropriately False positives and false negatives should be taken seriously and understanding what diagnostic results is vital for recommendations on the physicians partLearning from experience and suboptimal rules in decision makingOverconfidence in case study judgmentsThe information decision makers have the confident they are in their decisions But this isn t reflective of the actual accuracy of their predictionsA progress report on the training of probability assessorsCalibration of probabilities The state of the art to 1980How do you tell how good someone is at making predictions If a person assesses the probability of a proposition being true as7 and later finds that the proposition is false that in itself does not invalidate the assessment However if a judge assigns7 to 10000 independent propositions only of 25 of which subseuently are found to be true there is something wrong with these assessments For those condemned to study the past Heuristics and biases in hindsightThe idea that we can learn from the past is in some aspects overrated We tend to focus on salient details rather than the ordinary ones and string them together in causal diagrams We also tend to view the past with the foreknowledge of how it will end In real decisions in the present we do not have that luxury Inevitably we are all captives of our present personal perspective We know things that those living in the past did not Historians do play new tricks on the dead in every generation Evaluation of compound probabilities in seuential choiceHumans are really bad at compound probabilities probabilities based on seuential events Conservatism in human information processingBaye s theorem gives the user updated probabilities based on new information But the probabilities predicted by Baye s theorem are much higher than those that humans make Humans are much conservative Probably partly because we don t like getting into 90% That s why using odds instead of probabilities is probably easier to interpretThe best guess hypothesis in multi stage inferenceWhen making multi stage inferences humans tend to use the best guess hypothesis make your best guess and pretend it s actually 100% true when taking action rather than taking into account other possibilities that still might existInferences of personal characteristics on the basis of information retrieved from one s memoryWhen making decisions based on memory the user should take into account 1 diagnostic value of the information available and 2 the reliability of the information available Humans tend to ignore the latterThe robust beauty of improper linear models in decision makingThis was an interesting topic Let s say we re evaluating student applications for graduate school You could use a regression model that takes into account GRE scores GPA etc Or you could use human evaluators Or even if you had an imperfect model improperly weighted these models will still do better than humans Humans are still useful though because their intuition into what factors are actually important is usually pretty goodThe vitality of mythical numbersAnother good one it looks at how humans can be overconfident in uick calculations The author looks at one uick calculation of how much stolen property in NYC is attributable to heroin addicts The numbers sound good perhaps to a newspaper reporter but they are terrible and can be countered by starting with different sets of data to arrive at different conclusionsIntuitive prediction Biases and corrective proceduresDebiasingImproving inductive inferenceFacts versus fears Understanding perceived riskOn the study of statistical intuitionsVariants of uncertainty
