Drilling Down on Public Opinion on Evolution


PZ Myers and Marginal Utility both have very useful posts on recent public opinion polling on evolution that show how views on evolution differ between religous groups and education. Not unexpectedly, fundamentalists Christians support creationism in very large numbers. Surprisingly, this is the only group where education does not change views at all.

Here are highlights from PZ Myers' analysis:





In this graph, the blue bars are good, they mean the respondents in that religious group answered correctly that humans evolved from other animals. The purple bars are bad, that means the group insisted on giving the wrong answer.

Notice the sudden shift: the fundamentalist/moderate protestants have a majority that gets it all wrong, while the liberal protestants/Catholics have a majority that get it right. Then the Jewish/liberal others and nonbelievers do much better, but even the best of the bunch are only up around 60-70%. And overall, less than half the country gets the question right, and the people who reject evolution edge out the people who accept it.

. . .

No, wait—there's another variable to consider: education. Here are the same data, filtered to include only those members of each group who have had some college education. The numbers go up everywhere except for one benighted group.


The axes are scaled differently, so you have to inspect the numbers carefully to compare the two graphs, but look! With a little college education, a Catholic becomes about as smart as your average unbeliever. The liberal Jews and the unbelievers soar up to 80%…OK, 80% still isn't great. It means the average grade has shifted from a C to a B, but we take any improvement we can get. . . .

Look over on the left, though. The fundamentalists haven't budged in the slightest—on this subject, they are completely refractory to education. What isn't in the data is whether that is because that group maintains its beliefs by sending their young off to bible "colleges" which reinforce erroneous ideas, or whether it's because people who start off as fundies and get a college education then stop being fundies. It's probably a combination of both.

The biggest single religious group in this sample were the fundamentalists, and they are, of course, also the group most likely to get the answer wrong. They are also the group with the smallest percentage of college attendees; they aren't even trying very hard to get educated, and when they do, as we see in the second chart, it doesn't matter.

Now the surprise: the non-religious are the third largest category in the sample (it's a bit artificial, though, since the protestants are split 3 ways), and are almost 18% of the population. They also have the second smallest percentage of college attendees. That's a bit unexpected. It implies to me that "none" might be kind of a grab-bag category, though—although it also defies the stereotype of the godless as snooty college professors, and instead says there are a lot of ordinary folk who sensibly reject organized religion.


Read it all.

I think that the term "evolution" has to be better defined. It seems that there are two schools of thought regarding evolutionary evidences.

One is the application of the incrimental causes of evolutionary change, which of course, must be limited to natural.

The other would be faith in a intended incrimental design, stretching out the end product or completed creation over a period of eons.

We know that we share a common primate ancestor from the discovery of retro virus chromosomes, but we cannot know whether it was just a common temporary cell for a particular time during the process or just faulty or circumstantial evidence.

One thing is for certain. We came from primates. So anyone that believes that humans were created apart from primates are dead wrong.

I happen to believe that God channeled and channels material and life into existence and also channels information on the processes to carry out his intended creative plan.

Atoms are great evidence of this, in that a type of harmonious wave of info or vibes directs the electromagnetic charges for each atom, hence the very future activity of the atoms and all the molecules, chemicals, cells and organs from there. As though it was spoken into existence. It's this invisible or anti-atomic order which makes one know for a fact that an extra-universal source planned this creation. A source not dependant on laws of this universe, a source with no origin.
