The National Science Foundation has been engaged in the project of trying to formulate and promote such a measure for quite some time. A few years ago it came to the conclusion that the item "human beings, as we know them today, developed from earlier species of animals," shouldn't be included when computing "science literacy." The reason was simple: the answer people give to this question doesn't measure their comprehension of science. People who score at or near the top on the remaining portions of the test aren't any more likely to get this item "correct" than those who do poorly on the remaining portions. What the NSF's evolution item does measure, researchers have concluded, is test takers' cultural identities, and in particular the centrality of religion in their lives.' Kahan also had a previous, related post on the interaction between religiosity and scientific literacy."

      Actually, people can "believe" in science. Just as they can believe in anything else, including religion. Most people actually do that.

      They hear that some scientist found out something awesome. Like, say, how a laser works. And they might use a DVD player which incidentally use a laser, without having the slightest clue just how that thing works, or what the science behind it is. For all they care, or know, it could as well work with pixie dust and magically operated by faeries.

      The difference is that they have the option not to believe but to test what is scientifically produced. They can build their own laser (time, money and skill provided) and it WILL work.

        I don’t think you’ve got your definition of “believing” quite right - there’s no reason to require “belief” to be unsubstantiated. In fact we very often hear scientists say things like “I believe that [x], and here’s why”. To “believe” just means to hold something to be true.

        In fact, philosophers have long defined “knowledge” as “justified true belief”. There’s lots of variations on that theme, and arguing about whether that’s a right definition - but the argument is not about the “belief” part as much as the “justified” and “true" parts.

        So, it is in fact incorrect to say that science eliminates the need for believing - what it does, however, is provide reasons or justification for our beliefs.

      No, you misunderstand.

      Everything you think is true is something you believe. If someone says, "1+1=2," you say, "Yes, that is true." What you really mean is, "Yes, I believe that to be true." Certainly, things are true or false absent of any belief, but when we're asking about whether or not an individual thinks something is true or false, we're exactly talking about belief. We're not talking about accuracy of scientific or mathematic laws, theories, or models. We're talking about the nature of knowledge, perception, and human understanding.

      Think of it this way. For thousands of years humans believed that when they saw a sunrise that the sun had revolved around the earth on a crystal sphere. That's what their knowledge of the universe told them was true, so that is what they believed, and that's what their knowledge told them they saw. That was as true to them as the truth you belive in when your knowledge tells you that the earth is held in orbit by gravity and rotates to bring the sun back into view. The fact that your knowledge might be more accurate or might have more evidence behind it is irrelevant. Your belief that it is true, or belief that it is false, or fundamental misunderstanding of what is truly going on doesn't change what's really going on. Nevertheless, knowing who agrees with your beliefs and therefore agree with what the common knowledge tells us about the universe can be valuable.

      You can do the same thing with any scientific model. Consider big bang vs steady state theory. Did you know that, to this day, scientific papers are published in journals relating to the steady state model of the universe? Consider the model of the atom. We've gone from the plum pudding model, to the ring model, to the Bohr model, which is still the most commonly taught model, I believe. None of them really represnt the atom that well, of course, but people still imagine the Bohr model when you say "atom" to them. That's not what an atom actually is or looks like, but that is what people believe.

        It's not really faith. I, coming from a mathematics background, would rather call it interpolation. You have a few findings that you have, these are (more or less) well dated and they tell you some kind of timeline. What you do now is fill in the blanks. As science progresses and we find more, fewer blanks need filling, and some of the stuff that people filled in will have to be erased and reworked because what we found contradicts what they envisioned.

        That's the main difference between a scientific and a faith based system, not so much the steps "research" is done, but rather their order.

        Science goes
        observation of nature
        pondering of meaning
        formulation of theory
        more observation of nature
        adjustment of theory

        Religion goes
        creation of holy text (aka "truth")
        observation of nature
        pondering how observation can be interpreted to fit holy text
        more observation of nature
        discarding observations that don't fit holy text

        The main difference is that science adjusts its theory to fit the findings, religion accepts or rejects the discoveries depending on whether they fit into the holy scriptures.

      The point of a multi-question test is that the questions should measure different things - they won't all necessarily correlate well with each other. Measuring someone's inclination to believe religion over science would seem to be a valuable part of assessing their scientific literacy.

      • Um, you've just ignored the data in front of you - the data collected shows no correlation between "someone's inclination to believe religion over science" (ie their position on the evolution v creationism debate) and scientific literacy.

          They're trying to measure "scientific literacy" (which is a stupid term). The answers to the evolution question don't correlate with the answers to the other questions because it's measuring something different. They've concluded it's measuring people's inclination to believe in religion, presumably over science. That would seem to be an important factor in scientific literacy, so the evolution question is actually capturing something that is missed by the other questions.

            Further it raises the question as to who is trying to change the test, and why ;)

    • The main difference, independent of how "well" religious vs. non-religious people scored, would probably be how they accept those "scientific facts".
