Where Do They Get It Right? :: Intelligent Design

Welcome to part two of an infinite part series of entries on Evolution, Intelligent Design, Neo-Darwinism, Academic Freedom, Creationism, and Teaching The Strengths and Weaknesses of Scientific Theories.

As before, I will try my best to point out where a group actually has some validity and give them credit.  I want to be as balanced as I can in this series, but I realize that I have my biases.  Therefore I need YOU to point out where I'm wrong.  Let's work together on this, Team.

Today's Topic: Intelligent Design!

Intelligent Design (ID) is the belief that we can scientifically detect intelligence in nature.  

ID proponents often make analogies to illustrate their point.  Mount Rushmore is an example of an analogy that is commonly used.  

The claim is that if you look at Mount Rushmore, you know that there is a lot more going on than just a mountain.  Even if you were an alien from outer space that landed on this planet, you could tell that it was not something that just happened naturally.

Another major claim that ID proponents push is Irreducible Complexity (IC).  IC is more scientific and breaks the anatomy of life down to the cellular level.  According to IC there is a limit to what is capable of evolving.  Highly coordinated biological systems like the endocrine system are too complex to have evolved through natural selection, non-random mating, gene flow, genetic drift, and mutation.

ID proponents claim that life requires a designer to have evolved.  They use the previously mentioned analogies and IC, in addition criticizing the current science of evolution, the big bang theory, chemical evolution, biogenesis, and geology to make their point.  ID proponents believe that life at the molecular level is too complex to have arisen through natural causes.

Most of my information on ID will come from The Discovery Institute's web site and podcast.  The Discovery Institute is an organization devoted to developing and promoting ID as a scientific theory.  Unlike other web sites or movies like Expelled, The Discovery Institute often uses real and current science to try to prove their point, making their arguments more valid and credible.

Intelligent Design:  Where Do They Get It Right?
Despite what skeptics and atheists say, Intelligent Design is not creationism.  It attempts to be a legitimate scientific theory, and is more broad than creationism.  Intelligent Design proponents can be members of any religion including agnostic and atheist, whereas creationists are primarily Jewish, Muslim, and Christian.

ID only attempts to find intelligence in the design of nature.  The interpretation is then up to the student to decipher for themselves.  For theists, the original designer may be their god.  For non-theists, the designer could be extra terrestrial.  Since ID can have natural explanations, it's difficult to argue that ID = religion. 

The Discovery Institute does not endorse the teaching of ID in the classroom.  According to the Casey Luskin of the ID The Future podcast, the Discovery Institute advised the Dover school board against teaching ID in the classroom during the famous Kitzmiller v. Dover trial in 2005.  The Discovery Institute's stance is that ID needs to be developed as a strong theory first.  Once enough sufficient evidence has been gathered, the theory will be too strong to be rejected by school boards.

There are also some misconceptions about the Dover trial that atheists and skeptics frequently get wrong.  The book titled Of Pandas And People is a biology text book that teaches ID.


During the trial, it was shown that previous copies 
of this text book contained the words "Creator" 
and "Creation." Later drafts had those words 
replaced with "Designer" and "Design." The 
interpretation was that the book was a creationist 
text that had been converted to an Intelligent 
Design text, and therefore 
Intelligent Design = Creationism, and teaching 
Creationism is unconstitutional. However, if we 
look at the content of the book, there is no 
mention of Adam and Eve, religion, talking snakes, 
Towers of Babel, or anything else remotely biblical 
in the original texts. The word "creator" is not 
necessarily synonymous with God, but this was 
how it is interpreted by anti-ID groups.

Intelligent Design:  Where Do They Get It Wrong?
Irreducible Complexity (IC) is the most compelling argument that ID proponents have.  The biochemistry of the human body is amazingly coordinated.  It's easy to see how someone can conclude that certain biological systems and processes are too complex to have originated from natural selection, non-random mating, gene flow, genetic drift, and mutation.  There is a famous animation made by Harvard University that shows the processes that happen on the inside of a cell.  This video actually appears in the movie Expelled and is used as an illustration of how complex our body really is.



I can't begin to explain how all of this activity evolved 
from single celled organisms that existed 3 billion 
years ago.

We have some idea, but we may never fully understand.

The problem is that IC takes the lack of knowledge of 
an organism's history and concludes that it had to 
have been intelligently designed. There are two 
logical fallacies here (among others): an argument 
from igorance, and a false dichotomy. The argument 
from ignorance is when we try to draw a conclusion 
from a lack of information. In this instance, we don't 
know everything about the evolution of a cell.  
However, the lack of information about our current 
understanding does not equal positive evidence for 
design. A false dichotomy is the assumption that there 
are only two choices. In this case those choices are 
Evolution or ID.

Why can't we have a third or forth choice? Let's get 
creative! Depending on your opinion, the features of 
an organism depicted in the above video could have 
been produced by natural selection, non-random 
mating, gene flow, genetic drift, and mutation.  If you 
disagree, ID doesn't have to be the alternative.  What 
if there is some other natural mechanism that hasn't 
been discovered yet?  Let's pull out out microscopes 
and get thinking rather than drawing something from 
nothing.

Another problem with ID is the constant use of 
analogies to prove the existence of intelligence.  
Let's examine these two situations:

> Humans and aliens can detect that there was 
intelligence behind the creation of Mount Rushmore.  

> Archaeologists find cave drawings and can determine 
that they were made by beings with intelligence. 

These are both examples of identifying human-like intelligence.  Humans can identify natural processes like wind and water erosion, earthquakes, tornadoes, etc.  It's rare that someone will go outside after a hail storm to find damage to their car and scream, "Which one of you fucking kids dumped 250 golf balls on my car from the top of my roof and then cleaned up the balls, leaving no evidence behind?"

When we look up at Mount Rushmore, we see the remarkable shape of human faces in the rock.  We recognize that it would be highly unlikely that the wind and rain would have eroded the mountains in such a miraculous way.  This would not be enough for us to make our conclusion that it was intelligently designed.

We would have to ask ourselves, "How else could this have been done?"  In the case of Mount Rushmore, little investigation is needed.  There is a tourist info center nearby that will explain the entire process to you.  We know what human beings are capable of, and we know that humans using sculpting techniques on a large mountain is a more likely explanation than a tornado (or some other natural cause) eroding a mountain into the detailed shape of our forefathers.

In the case of the cave drawings, we need to investigate a bit more.  What was used to make these paintings?  Who could have lived in this cave?  How old are these paintings?  Is there any evidence of ancient inhabitants?  Is it possible that wind could have blown these materials onto the wall in this manner?  Could a paint-like substance have dripped onto the wall this way?

These are all questions that we can investigate and associate with human-like intelligence.

We can't ask these same questions with Intelligent Design.  

"How could a cell have been produced in this complex manner?"

"Who did it?"

"What was the process?"

Intelligent Design admittedly refuses to answer these questions.  According to the Discovery Institute, ID does not study the designer or the processes by which nature has been designed.  Their web site reads, "The scientific theory of intelligent design is agnostic regarding the source of design."

How does the Discovery Institute think that they are going to develop a theory without studying the cause or the process?  

Even if you are a non-theist that believes that aliens somehow planted life here, you'd have to come up with proof of an alien visitation or a mechanism by which aliens were able to synthesize life, and then send it to earth.  

Unless some profoundly compelling evidence arises, I can't see how ID would ever become a solid theory that would be acceptable for teaching in a classroom.

Conclusion:  Intelligent Design Is Not Solid Science And Needs More Evidence
Unfortunately for Intelligent Design, they're building a theory on a pick and choose foundation.  Every theory in science will ask who, what, when, where, and how, but Intelligent Design chooses not to ask the "who" and "how."  Instead, they make poor analogies, attack current science, and in some cases (groups outside of The Discovery Institute) drudge up creationist arguments that have been disproved for decades.

It reflects poorly on the theory to team up with those who are not up to date on the science and the arguments for or against that science.  The Discovery Institute and other groups tend to team up with anyone who will agree with their cause.  I tend to be more sympathetic to people like Michael Behe and Casey Luskin who use current science to gain credibility rather than scare tactics.  Yet The Discovery Institute fully supports and advertises when a movie like Expelled comes out, which has more scary images from the holocaust than actual science.

If The Discovery Institute spent less time supporting propaganda, and more time on science, they might be able to get people to listen to them.

  1. " I tend to be more sympathetic to people like Michael Behe and Casey Luskin who use current science to gain credibility rather than scare tactics. "When did they start doing that? Neither one has published anything remotely resembling evidence for ID. Nor do they seem eager to answer their critics. Luskin, in particular, likes to expound on the fossil record (a subject in which he has no expertise) from the comment free safety of Evolution News and Views. They cry persecution without even trying to do the work that every other scientist in the world is required to do to get a hearing. It is a fundamentally dishonest enterprise.

  2. Agreed. My point was more that I will actually listen to their arguments because they listen to the current state of the argument, and try to come up with new "problems" with evolution. They aren't touting outdated arguments that have been debunked since the 70's.

    Even if I don't agree with the ID/creationists, their hole poking does lead to new scientific discoveries when scientists set out to prove them wrong. I find their arguments interesting and more worthy (opposed to being completely worthless), yet I have a long way to go before being convinced.

  3. Well, I'd say they are the same sort of arguments that creation science posed in its heyday. The Irreducible Complexity of the eye has given way to the flagellum. Same argument, not even more sophisticated. And Dembski needs to define his terms and run his stuff by some mathematicians and information theorists to gain any traction. They just refuse to play with the big boys. Heres a sample of the latest inane blatherings from the Discovery Institute.

  4. Sure. Again, I'm in agreement with you. They say a lot of crazy things. I'm a regular listener to their podcast and there are episodes that I can't even make it through because of how bad they are.

    I'm not trying to promote ID in anyway. i don't want to stick up for these guys but I will give them some credit for making me look at the argument in a different way. I don't think it's a bad idea to test for the boundaries of our current understanding of evolution. Maybe there's some other evolutionary mechanism that we can discover by hearing such extreme arguments. I don't credit them with making any of these findings, and I DEFINITELY credit them with jumping the gun and using bad logic.

    I'm trying to sift through the garbage and say, "Yeah, they speak a lot of horse shit over here, but over here, maybe there's something new that can be discovered."

    Everyone says stupid things. I could easily tear ID down by pointing out all of the dumb things that they say, but I prefer to try find the common ground and the positives.

    But that's just me. Maybe I'm an idiot.

  5. It's not the ideas, but the approach that bothers me. There is a self-policing system set up that works pretty well and that they don't take advantage of. Wegener and Margulis were roundly denounced but you didn't see them bitching to school boards or making movies to build their cases. You do the work and, if there is anything to it, you get a fair hearing. I've been dealing with these guys (on a local level - I'm just an interested amateur) since the Creation Science push 30 years ago and the one thing the creation scientists and ID proponents have in common is their intellectual dishonesty and cowardice. Some of these guys have the smarts to actually add to the sum total of human knowlege but none of them seem to be able to grasp the concept that they could be wrong. If they are unwilling to swim in the big pond I don't know how you separate the ones that are just ignorant from the ones that are flat out liars. I'm certainly not qualified to judge. I liked your post, anyway. I thought it was pretty well thought out.

  6. Absolutely, although I will say that I always refuse to accept the argument that the opposite side is just lying. I can't believe that someone who believes in a cause would start a web site, an entire scientific theory, and/or a podcast, just to lie to people to get them to think the same way as they do. This is what people claim on all sides all of the time, and I think that once you step into that mode of thinking, you're just insulating your beliefs against criticism - no matter what side you hear it from. This is what the conspiracy theorists and/or non-skeptics do as a tactic, and I refuse to adapt it.

    I don't want to keep defending ID because I really don't like doing it, but I guess I got myself into this mess. I'll just kind of leave it here since we're pretty much on the same page.

    If someone else wants to, go for it.

    Thank you very much for reading, sharing, and disagreeing.
