stock IQ tests are problematic on many levels — not least , because they do very little to tell us about the caliber of our thinking . depend to get the better of this oversight , psychologist Keith Stanovich has set about to work out on the first - ever Rationality Quotient test . We spoke to him to learn more .
Keith E. Stanovich is Professor of Human Development and Applied Psychology at the University of Toronto . The writer of over 200 scientific articles and seven record book , he , along with Richard West , was late given a grant by theJohn Templeton Foundationto create the first comprehensive assessment of intellectual mentation — a test that will ultimately determine a individual ’s ‘ rationality quotient ’ .
And indeed , the value ofrationalityand “ good thinking ” lean to be diminished by the grandness we pose onintelligence . But as we learn from Stanovich , the two often have very trivial to do with each other .

Do n’t stock IQ tests already measure for rationalness — and does n’t intelligence correlate with reason ?
intelligence quotient [ tests ] do not at all now measure processes of intellectual cerebration , as they are defined by cognitive scientists .
This is why a freestanding mental test is needed to assess RQ . We — my colleague Richard West and I — were precede many years ago to through our longstanding interest in the heuristic rule and biases enquiry programme inaugurated by Daniel Kahneman and Amos Tversky several decades ago .
This all got started back in 2002 when Kahneman won the Nobel Prize in Economics ( Tversky go in 1996 ) . Thepress releasefor the award from the Royal Swedish Academy of Sciences draw attention to the roots of the honour - winning workplace in “ the analysis of human sagaciousness and conclusion - making by cognitive psychologist . ”
Kahneman was exalt for discovering “ how human judgment may take heuristic cutoff that systematically depart from basic principles of probability . His work has inspire a young propagation of researchers in economics and finance to enrich economical theory using insight from cognitive psychology into intrinsical human motivation . ”
One reasonableness that the Kahneman and Tversky body of work was so influential was that it address deep issues concerning human reasonableness . Their work , along with that of many others , has shown how the basic architecture of human cognition make all of us prone to these frightful fault of judgment and decision making .
But being prone to these error does not mean that we always make them . Every mortal , on some function , override the tendency to make these logical thinking errors and rather makes the rational response . It is not that we make error all the clip . Even more importantly , our research group has shown that there are systematic difference among individuals in the tendency to make errors of discernment and conclusion making .
And the fact that there are taxonomic individual differences in the discernment and decision pee situations studied by Kahneman and Tversky means that there are mutation in important property of human cognition related to rationality — how effective we are in achieving our goal .
This fact is rummy because most laypeople are prostrate to think that IQ tests are mental test of , to put it conversationally , good mentation . Scientists and laypeople likewise would tend to agree that “ good thinking ” encompass safe judgment and conclusion qualification — the character of thinking that helps us attain our goals . In fact , the type of “ good thinking ” that Kahneman and Tversky studied was hold so important that enquiry on it was awarded the Nobel Prize . Yet assessments of such secure thinking are nowhere to be found on IQ psychometric test .
Are you concerned in how cognitive bias affect reason ? Which I should we be most aware of ?
Absolutely . Cognitive biasesare an all important part of the modern definition of rationalness in cognitive science .

To think rationally intend accept the appropriate natural process given one ’s goals and beliefs — what we call instrumental rationality — and holding opinion that are in synch with usable evidence , or epistemic reasonableness . Collectively , the many tasks of the heuristics and biases program — and the even wider lit in decision scientific discipline — be the operational definition of rationality in forward-looking cognitive science ( see my bookRationality and the Reflective Mind , 2011 ) .
have me give you some object lesson of subservient rationalness and irrationality :
The power to display disjunctive abstract thought in determination making [ for instance Either the Sun orbit the Earth , or the Earth orbits the Sun . The Sun does not orbit the Earth . Therefore , the Earth orbit the Sun . ]
The propensity to show inconsistent preferences because of frame effects [ for example saying a ‘ glass is half empty ’ can often be more persuasive than suggesting the inverse ; this is somewhat related to to the negativity bias ]
The tendency to show a default preconception [ a.k.a . the status quo preconception in which we bear a preference for the way things presently are ]
The tendency to replace affect for unmanageable evaluation [ sometimes when we have to answer a difficult doubtfulness we actually answer a related to but unlike enquiry without see a substitution has taken place ]
The tendency to over - weight short - terminus rewards at the disbursement of foresighted - term well - being [ which is also mention to as the current moment bias ]
The propensity to have choices strike by vivid stimulus [ e.g.men have been shown to make poor decisions in the mien of an attractive female ]
The disposition for decisions to be affected by irrelevant context
Likewise , they have analyze aspects of epistemic reason and irrationality , such as :
The disposition to show incoherent probability assessments
The inclination toward certitude in knowledge judgments
The leaning to neglect substructure - pace [ a.k.a . the base rate fallacy;sometimes we do n’t take new information into history when make chance assessments ]
The tendency not to attempt to fake hypotheses
The tendency to seek to explain fortune events
The inclination toward self - serving personal judgments
The inclination to evaluate grounds with a myside prejudice [ where we only assay out perspectives that are openhearted to our own ]
The tendency to push aside the alternative hypothesis
You just begin a 3 - class task to make the first comprehensive assessment of rational thinking . Why do we postulate such a thing ?
All of the biases and processes listed above will be on our prototype bill of rational thinking that will be the outcome of our Duncan Grant from the John Templeton Foundation . It is necessary to appraise them forthwith on such a exam because none of them are directly assessed on IQ exam .
However , there is an important caveat here . Although the tests fail to assess intellectual thinking directly , it could be argued that the processes that are tapped by IQ tests largely overlap with variance in rational intellection ability .
Perhaps intelligence is highly link with rationality even though task tapping the latter are not assessed directly on the tests . Here is where empiric research comes in — some of which has been generated by our own research chemical group . We have found that many rational mentation tasks show surprising degrees of dissociation from cognitive power in university sample . Many Greco-Roman effects from the heuristic program and biases literature — base - rate neglect , set up core , continuative effects , ground biases , and termination preconception — are only modestly related to intelligence if run in between - field of study designs .
Most rational thinking undertaking correlate to some degree with intelligence , but the correlation is almost always restrained enough ( .60 or so at the very highest ) to still create many case where intelligence and reason are out of synch . Hence my coining of the term dysrationalia in the early 1990s .
And what do you intend by “ dysrationalia ” ?
I coined the term dysrationalia — an analog of the Holy Writ dyslexia — in the early-1990 ’s so as to draw aid to what is miss in IQ tests . I delineate dysrationalia as the inability to think and behave rationally despite having tolerable tidings . Many people display the systematic inability to think or bear rationally despite the fact that they have more than adequate IQs .
One of the reasons that many of us are dysrationalic to some extent is that , for a variety of reason , we have come to overvalue the kinds of thought process skills that intelligence quotient test measure and undervalue other critically crucial cognitive skills , such as the power to think rationally .
What are some examples of a person exhibiting grim reasonableness ? What are some unexpected or lesser live “ risks ” of not think completely rationally ?
In my bookWhat Intelligence Tests Miss(2009 ) , I start with a discussion of David Denby ( NY Times writer ) and John Paulos ( maths professor ) induce disastrous someone investment funds decisions . I also discuss how many sense that George W. Bush was dysrationalic .
But in term of specific , here are some irrational thinking tendencies to consider :
Physicians choose less effective medical treatments
hoi polloi fail to accurately value risks in their environment
data is misused in legal transactions
Millions of dollars are drop on unnecessary task by government and private manufacture
Parents break to inoculate their children
Unnecessary surgery is performed
beast are hunt to quenching
Billions of dollars are wasted on quack medical curative
high-priced fiscal misjudgments are made
Is rationality something that ’s innate ? Or is there hope for people with low RQ ?
Rationality is not entirely innate . It is as malleable as intelligence and perhaps much more so . more or less one half of rationality as we define it is not cognitive process but knowledge — noesis that could be acquired by perhaps 70 % or more of the population .
Here ’s what I mean : The theoretical account of individual difference in rational thought that West and I have put together sectionalisation rationality into fluent and crystallized component part by doctrine of analogy to the Gf and Gc of the Cattell / Horn / Carroll fluid - crystallized theory of news .
Fluid rationality encompasses the unconscious process part of rational thought — the thinking disposition of the contemplative mind that moderate to rational thought and action . Crystallized rationality comprehend all of the knowledge complex body part that interrelate to noetic intellection .
These knowledge social organisation are the tools of reason ( probabilistic thinking , logic , scientific reasoning ) and they represent declaratory noesis that is often incompletely acquire or not acquired at all . But they can be acquire by most and in this sense rationality is teachable .
Rational thought process errors due to such noesis gaps can occur in a potentially big set of logical cognition bases in the world of probabilistic logical thinking , causal reasoning , knowledge of risks , logic , practical numeracy , fiscal literacy , and scientific thought process ( the importance of alternate hypotheses , etc . ) .
