What is the four-digit number in which the first digit is one-fifth the last, and the second and third digits are the last digit multiplied by 3? Hint: The sum of all digits is 12 2. Jane went to visit Jill. Jill is Jane's only husband's mother-in-law's only husband's only daughter's only daughter.

What relation is Jill to Jane? Which of the words below is least like the others? The difference has nothing to do with vowels, consonants or syllables. Who were the smartest presidents?

She likes mutton but not lamb, and she likes okra but not squash.

Following the same rule, will she like cherries or pears? What is the number that is one more than one-tenth of one-fifth of one-half of 4,? In a foot race, Jerry was neither first nor last. Janet beat Jerry, Jerry beat Pat. Charlie was neither first nor last. Charlie beat Rachel. Pat beat Charlie. Who came last? Jane's daughter Jane's mother's husband is Jane's father, his daughter is Jane, and Jill is her daughter 3.

Zipper the others can be anagrammed into the names of cities: Rome, Paris, Chester 4. Indeed, IQ scores have long been criticised as poor indicators of an individual's all-round intelligence, as well as for their inability to predict how good a person will be in a particular profession. The palaeontologist Stephen Jay Gould claimed in The Mismeasure of Man in that general intelligence was simply a mathematical artefact and that its use was unscientific and culturally and socially discriminatory.

Howard Gardner at the Harvard Graduate School of Education has been arguing - controversially - for more than 25 years that cognitive capacity is best understood in terms of multiple intelligences, covering mathematical, verbal, visual-spatial, physiological, naturalistic, self-reflective, social and musical aptitudes.

Yet unlike many critics of IQ testing, Stanovich and other researchers into rational thinking are not trying to redefine intelligence, which they are happy to characterise as those mental abilities that can be measured by IQ tests.

Rather, they are trying to focus attention on cognitive faculties that go beyond intelligence - what they describe as the essential tools of rational thinking. These, they claim, are just as important as intelligence to judgement and decision-making. As an illustration of how rational-thinking ability differs from intelligence, consider this puzzle: if it takes five machines 5 minutes to make five widgets, how long would it take machines to make widgets?

Most people instinctively jump to the wrong answer that "feels" right - - even if they later amend it. When Shane Frederick at the Yale School of Management in New Haven, Connecticut, put this and two similarly counter-intuitive questions to about students at various colleges and universities in the US - Harvard and Princeton among them - only 17 per cent got all three right see "Test your thinking".

A third of the students failed to give any correct answers Journal of Economic Perspectives, vol 19, p We encounter problems like these in various guises every day. Without careful reasoning we often get them wrong, probably because our brains use two different systems to process information see New Scientist, 30 August , p One is intuitive and spontaneous; the other is deliberative and reasoned. Intuitive processing can serve us well in some areas - choosing a potential partner, for example, or in situations where you've had a lot of experience.

It can trip us up in others, though, such as when we overvalue our own egocentric perspective. Deliberative processing, on the other hand, is key to conscious problem-solving and can help us override our intuitive tendencies if they look like leading us astray. The problem with IQ tests is that while they are effective at assessing our deliberative skills, which involve reason and the use of working memory, they are unable to assess our inclination to use them when the situation demands.

This is a crucial distinction: as Daniel Kahneman at Princeton University puts it, intelligence is about brain power whereas rational thinking is about control. Bush incongruity of people who are supposedly smart acting foolishly. The idea that Bush is just one foolish smart person among many, and that intelligence is a poor predictor of "good thinking", comes from a series of recent experiments that compared the performances of people of a range of intellectual abilities on rational-thinking tasks.

In a study published last year, Stanovich and Richard West of James Madison University in Harrisonburg, Virginia, found there was no correlation between intelligence and a person's ability to avoid some common traps of intuitive-thinking Journal of Personality and Social Psychology, vol 94, p On certain types of thinking tasks, such as those involving number ratios, probabilities, deductive reasoning and the use of hindsight, intelligent people do perform better, Stanovich and others have found.

This is particularly true when any intuitive pitfalls are obvious, especially if a correct answer depends on logic or abstract reasoning - abilities that IQ tests measure well. But most researchers agree that, overall, the correlation between intelligence and successful decision-making is weak.

The exception is when people are warned that they might be vulnerable to a thinking bias, in which case those with high IQs tend to do better. This, says Evans, is because while smart people don't always reason more than others, "when they do reason, they reason better". For example, consider the following problem. Is a married person looking at an unmarried person? If asked to choose between yes, no, or cannot be determined, the vast majority of people go for the third option - incorrectly.

If told to reason through all the options, though, those of high IQ are more likely to arrive at the right answer which is "yes": we don't know Anne's marital status, but either way a married person would be looking at an unmarried one. What this means, says Stanovich, is that "intelligent people perform better only when you tell them what to do". Perkins explains this as follows: "IQ indicates a greater capacity for complex cognition for problems new to you.

But what we apply that capability to is another question. Think of our minds as searchlights. IQ measures the brightness of the searchlight, but where we point it also matters.

Some people don't point their searchlights at the other side of the case much, for many reasons - entrenched ideas, avoidance of what might be disturbing, simple haste.

A higher wattage searchlight in itself is no protection against such follies. A survey of members of Mensa the High IQ Society in Canada in the mids found that 44 per cent of them believed in astrology, 51 per cent believed in biorhythms and 56 per cent believed in aliens Skeptical Inquirer, vol 13, p The idea that IQ is a poor measure of rationality is not without its critics, though. In a study of Pittsburgh residents aged between 18 and 88, her team found that, regardless of differences in intelligence, those who displayed better rational-thinking skills suffered significantly fewer negative events in their lives, such as being in serious credit card debt, having an unplanned pregnancy or being suspended from school Journal of Personality and Social Psychology, vol 92, p
