Intelligent Men Look Different – Says Science

By Anupum Pant

Background

I know, I’m not a very big fan of intelligence scores or IQ points measured using the standard IQ tests available today. And even if this study does rely on those scores, I still find it pretty interesting. You will too…

Judging a book by its cover isn’t unwise after all. A recent study published by researchers from the Czech Republic proves that all of us humans have a natural ability to estimate how intelligent a man really is, by just looking at his facial features. That said, the study also mentions that you can’t judge a woman’s intelligence by observing her facial features. It works for only men. However, both men and women have this ability to estimate the intelligence of a man by looking at his face.

The study finds no solid correlation between the features of a woman’s face and their intelligence. That means, to find out about how intelligent a woman is, you’ll have to dig deeper than just the facial features.

People can accurately judge intelligence by looking at faces of men, but not women.

The study did not use a very huge sample – Still pictures of 40 men and 40 women were used. Nevertheless even 80 pictures contribute a significant amount to science. No experiment is a bad one. We’ll probably see more such studies and know more about the phenomenon in the near future.

They also measured the intelligence of these 80 people using standard IQ tests and asked people to rate their intelligence. It was found that people were able to almost accurately tell the IQ of a man by looking at his picture!

How do we do it?

We have an inbuilt ability to spot the shape and features of intelligent men. This could be a pretty logical evolutionary trait.

Faces of intelligent men: According to the researchers, longer faces with greater distance between the eyes, pointy chins, larger noses, slightly smiley lips are the features of highly intelligent men.

Faces of not so intelligent men: Whereas broader and rounded faces with eyes closer to each other, shorter faces, sad lips and bigger chins are the signs which tell us that a man is not so intelligent.

Here see the difference yourself. What do you think? Could you spot it? Which one of these faces is the closest to your face? Tell me in the comments below. Tell me about mine too.

Flynn Effect – IQ Test Scores say We Are Getting Smarter Every Year

By Anupum Pant

My Opinion of the IQ tests

I don’t like IQ tests (WAIS, WISC, etc). Why?

Well, IQ tests are designed with an assumed definition of the word “intelligence”. They assume that “intelligence” can be estimated by measuring how closely a person thinks like the other “intelligent” people (probably the ones who design the test). IQ tests measure general Intelligence, not “intelligence”. However, today general intelligence and intelligence are used interchangeably by most of us.

IQ tests are standardised tests that give you standardized test scores which merely indicate how well you would perform at other standardized tests (academic performance). Also, these tests are not an indicator of how well a person would do in his/her life.

IQ tests assume that General intelligence and Intelligence are the same things, or this is what the society has come to believe. To them, the other sub-intelligence types like interpersonal intelligence, intra-personal intelligence, musical intelligence, creativity, memory etc. mean nothing.

I think, intelligence is a much more complex quality than what IQ tests assume it to be. Quantifying intelligence is hard and presently no test does it properly; probably no test ever will…

For instance, the Megasavant, Kim Peek (Rainman) scored a below average (87 points) on general IQ tests. Agreed, he couldn’t button up his shirt, but he could speed read a book in about an hour and remember almost everything he had read. Besides, he could accurately recall the contents of at least 12,000 books which he had read in his life. And yet, this incredible ability meant nothing to the IQ tests. IQ tests looked at him as a guy with just a below-average IQ.

However, I’m not here to debate on IQ tests today. Let’s take it to the comments section. Tell me what do you think about these tests.

I like it or not, I can’t deny the fact that it is a world standard. And there is definitely a solid reason for that. So let’s just learn something about these tests…

The Flynn effect

Did you know, the IQ test scores are not absolute. The score you get is adjusted in a way that keeps the average IQ at 100 and also ensures that 2/3 people lie in an IQ band of 85-115 points.

But that is what IQ tests and scores are based on, so many people probably know that. There is one other thing you almost certainly did not know…

The WISC test: One of the widely used IQ test is called WISC (Wechsler Intelligence Scale for Children). It started in the year 1947, and to ensure that the average IQ remains 100, it has been recalibrated 3 times in the 70s, 80s and the 2000s decade. Today WISC IV is used.

Had our grandparents taken the present WISC IV test about a century back, they would have probably scored 70 points on an average. That would have classified them as mentally retarded! Clearly, we have become smarter. Or what?

Yes, in fact the constant increase in this average IQ test scores has been observed for a long time by scientists. They have measured a gradual rise of 3 points every decade and this effect is called Flynn effect. And that is the reason the test has to be recalibrated regularly – to keep the average at 100 points. Is this evolution doing its work?

Why does it happen

Frankly, no one knows for sure. Like the theories that offer explanation on what sleep exactly does to our brains, even Flynn effect has a couple of possible explanations. Three of the most plausible ones are these:

  1. “Better” schooling or in other words better training  at schools which makes students get familiar with the IQ test pattern, is one explanation. Our schools have evolved to impart education in a form that helps a kid do better at IQ tests. This is pretty clear from the way our present education system doesn’t give much importance to creativity, just like IQ tests don’t…although it beats me, why memory is given a substantial weight-age at schools.
  2. Improved nutrition is another explanation. Most certainly, excluding fast foods and other such foods, we eat better things than what our grand-parents used to. The inclusion of iodine in common salt is one such example. Also, parents these days ensure that the children in their formative years get the best nutrition – exactly at the time when the brain forms most connections. That could have clearly helped us get smarter.
  3. Some researchers have a different take on how better education and nutrition has helped us get smarter. They suggest that the better lifestyle, education and nutrition has had an effect on our IQs by reducing the intensity of infectious diseases.

What do you think? Do you agree with the IQ test system. Do you think it isn’t just a social phenomena? What else could be the reason that we are getting smarter? Tell me in the comments.
