The correct solution is forty-seven days. Subjects were first asked if the tallest redwood tree in the world was more than X feet, with X ranging from eighty-five to a thousand feet. Then the students were asked to estimate the height of the tallest redwood tree in the world. Given an anchor of a thousand feet, their estimates increased seven-fold.
Rather, they wanted to understand how these biases correlated with human intelligence. As a result, they interspersed their tests of bias with various cognitive measurements, including the S. The results were quite disturbing. What explains this result? One provocative hypothesis is that the bias blind spot arises because of a mismatch between how we evaluate others and how we evaluate ourselves.

So, if you're not too sure about your own intellect, it actually might be an indication that you're pretty intelligent — thoughtful enough to realize your limitations, at least.
Here are some subtle signs that you are considerably smarter than you think. Evolutionary psychologist Satoshi Kanazawa and colleagues found that , among Brits as well as Americans, adults who had scored higher on IQ tests when they were kids or teens drank more alcohol more often in adulthood than those who had scored lower.
Some other studies support that finding as well, including a paper published in the journal Intelligence that found nations with a higher average IQ score also tend to drink more beer and wine.
Interestingly, a study of young Swiss men found that moderate alcohol consumption was most strongly linked to high IQ. For a study, researchers looked at nearly 2, pairs of identical twins in the UK and found that the sibling who had learned to read earlier tended to score higher on tests of cognitive ability.
The study authors suggested that reading from an early age would increase both verbal and nonverbal i. However, a paper argued that the report didn't fully account for environmental and genetic factors that may have been driving the differences in intelligence. A growing body of research suggests that anxious individuals may be smarter than others in certain ways, according to Slate's coverage of several different studies on anxiety. In one study published in the journal Personality and Individual Differences , for example, researchers asked undergrads to fill out questionnaires in which they indicated how often they experienced worry.
They also indicated how often they engaged in rumination , or thinking continuously about the aspects of situations that upset them. Results showed that people who tended to worry and ruminate a lot scored higher on measures of verbal intelligence, while people who didn't do much worrying or ruminating scored higher on tests of nonverbal intelligence. Tomas Chamorro-Premuzic, business psychology professor at University of London, wrote an article for Harvard Business Review in which he discussed how the curiosity quotient and having a hungry mind makes one more inquisitive.
First, smarter people are generally more tolerant of ambiguity. Second, CQ leads to higher levels of "intellectual investment" and learning more over time. A Goldsmiths University of London study found that intellectual investment, or "how people invest their time and effort in their intellect," plays a major part in cognitive growth.
A study published in Psychological Science by the University of Minnesota Carlson School of Management's Kathleen Vohs revealed that working in an untidy room actually fuels creativity. In the study, 48 participants were asked to come up with unusual uses for a ping-pong ball. The 24 individuals working in neat rooms came up with substantially less creative responses than the individuals working in cluttered rooms.
And a study from the University of Groningen in the Netherlands found that disordered environments prompt people to be more goal-oriented. The findings suggest that we're hardwired to seek order in our lives whenever possible.
