Smarter people more prone to cognitive bias

Source:
Journal of Personality and Social Psychology
Cognitive Sophistication Does Not Attenuate the Bias Blind Spot.
West RF, Meserve RJ, Stanovich KE

Abstract
+ Show Spoiler +

Apologies for the title, but I had to be limited by character limit. The title should have been:
The Smarter People Get, The More Prone They Are to Cognitive Bias


Anyway...

We have always assumed that homo sapiens are rational. Logically, the more people know (READ: the more degrees are attached to their names), the easier and moer efficient people should get around with problems.

But a recent scientific research published at Journal of Personality and Social Psychology proves this notion on human intelligence is the opposite of it really is. The scientific study suggests that, in many instances, smarter people are more vulnerable to these thinking errors. Although we assume that intelligence is a buffer against bias—that’s why those with higher S.A.T. scores think they are less prone to these universal thinking mistakes—it can actually be a subtle curse.

West and his colleagues began by giving four hundred and eighty-two undergraduates a questionnaire featuring a variety of classic bias problems. Here’s a example:


In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?


Your first response is probably to take a shortcut, and to divide the final answer by half. That leads you to twenty-four days. But that’s wrong. The correct solution is forty-seven days.

The results were quite disturbing. For one thing, self-awareness was not particularly useful: as the scientists note, “people who were aware of their own biases were not better able to overcome them.” This finding wouldn’t surprise Kahneman, who admits in “Thinking, Fast and Slow” that his decades of groundbreaking research have failed to significantly improve his own mental performance. “My intuitive thinking is just as prone to overconfidence, extreme predictions, and the planning fallacy”—a tendency to underestimate how long it will take to complete a task—“as it was before I made a study of these issues,” he writes.

And here’s the upsetting punch line: intelligence seems to make things worse. The scientists gave the students four measures of “cognitive sophistication.” As they report in the paper, all four of the measures showed positive correlations, “indicating that more cognitively sophisticated participants showed larger bias blind spots.” This trend held for many of the specific biases, indicating that smarter people and those more likely to engage in deliberation were slightly more vulnerable to common mental mistakes. Education also isn’t a savior; as Kahneman and Shane Frederick first noted many years ago, more than fifty per cent of students at Harvard, Princeton, and M.I.T. gave the incorrect answer to the bat-and-ball question. (See question below.)

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. When considering the irrational choices of a stranger, for instance, we are forced to rely on behavioral information; we see their biases from the outside, which allows us to glimpse their systematic thinking errors. However, when assessing our own bad choices, we tend to engage in elaborate introspection. We scrutinize our motivations and search for relevant reasons; we lament our mistakes to therapists and ruminate on the beliefs that led us astray.

The problem with this introspective approach is that the driving forces behind biases—the root causes of our irrationality—are largely unconscious, which means they remain invisible to self-analysis and impermeable to intelligence. In fact, introspection can actually compound the error, blinding us to those primal processes responsible for many of our everyday failings. We spin eloquent stories, but these stories miss the point. The more we attempt to know ourselves, the less we actually understand. What do you think guys?


BAT AND BALL QUESTION
(Please reply with your answer, and please answer as spontaneously as possible.)
A bat and ball cost a dollar and ten cents. The bat costs a dollar more than the ball. How much does the ball cost?

yep 5 cents... although it took me a disheartening amount of time to come up with that.

Asking ambiguous questions with poor punctuation doesn't make intelligent people unintelligent.

Lets go with ego. Let me explain: Smart people know they are smart. They also want to answer the question in the least amount of time, and get on with doing things they deem more important. Some might even be lazy, and assume their intuition is powerful enough to get the right answer right away. Therefore, the hop to a reasonably justifiable conclusion using bits and pieces of data to support what they think the answer should be.

The punctuation in the Bat and ball question is fine...
All I can say is that maybe I am really smart because I am so bad with questions like that... However, I am probably just extra stupid.
EDIT: Thanks for the title change.

Bat + Ball = 1.1
Bat = Ball + 1
=> (Ball +1) + Ball = 1.1
Ball + Ball = .1
2Ball = .1
Ball = .05

Ohhh hmm yet my brain initially screamed "TEN CENTS! But I it's a trap! Better use algebra..."

x + x + 1 = 1.1
2x + 1 = 1.1
2x=.1
x=.05
x= ball = 5 cents
x +1 = bat = 1 dollar 5 cents

But that aside. Cognitive biases have been known for a while. In the end people generally will not be persuaded by logic alone but will fish for rationales that conform to their own positions. Being smart has nothing to do with getting past this problem. Dumb or smart, you'll be biased. It's really about having the ability to be open to all positions more than anything else.

This is actually one of the reasons I read Fox news and the National Review every now and then. I don't want to unknowingly become pigeon-holed with a blind liberal bias.

The punctuation is perfectly fine. They are short sentences, but that doesn't make them incorrect.

5 cents , and the bat cost 1 dollar 5 cents (makes more sense if you think of both of them together )

Well clearly none of the degrees attached to their names were math degrees. Some people go their entire lives without advancing far beyond a middle school understanding of math, even if their other areas are exceptionally strong.

Now watch this cleverness:
A bat and ball cost a dollar and ten cents. The bat costs a dollar, more than the ball. How much does the ball cost?
Suddenly the ball costs 10 cents instead of 5 cents. ****ing commas man. How do they work.
There is but one truth.
