    Got them all as well. I didn't see a challenge here.
    Just general knowledge if you ask me. But then I was schooled before the Dept of Education came about and I actually learned something.

      How much of that stuff did you learn in school? I think I knew most of it simply by being a science nerd. It ran in the family--my mother (a chem major) bought me Tom Lehrer's record with "The Elements" which I immediately transcribed, in order, Sb, As, Al, Se, H, O, N, Re, etc. I was maybe 11 years old.

        I learned absolutely none of it in school, and that was waaay back when we were supposedly getting a better education than the kids of today do.

          Yeah, I got in the top 6% for us 65+ codgers, but I learned ALL of that 'in school'....

          But I kind of question (or resent) the title, because I didn't GUESS at ANY of the questions to come up with (ALL) the Correct Answers.

    Although I had majors in English and Philosophy, avoiding math led to a minor in Science, thus 12 of 12. The sugar and cavity one had me pondering, but logic and reason led to the correct, or at least expected answer. I always liked essay better than multiple choice, as there are always answers that are not quite perfectly correct in multiple choice.

      Hell, Stormi, I had to wait until starting Grad School for an MBA to learn one of those basics...
      From the Intro To Business Law class...

      The "right answer" is usually "It Depends," followed by your reasons for taking either, any or both sides of the alleged 'argument.'

      Still useful in socio-political-economic-religious "discussions."

      :))))))

    Got all 12, and I suspect most of the Gulchers did very well.

    However, I didn't like the sugar or nuclear power/weapons question. The answers were not clearly correct.
    1. The sugar one does not provide adequate data for a conclusion. It is simply a correlation, and not a great R value.
    2. The nuclear weapons one asks this of the elements is "required" for both. It is quite possible to make both a nuclear weapon and a nuclear reactor without uranium.

    Interesting that "Asian" was left off the ethnicity demographic. Suspect we whiteys would be disappointed in our ethnic superiority here.

      And the Asians might be disappointed when compared to the Jews (according to The Bell Curve.)

        Really? I haven't seen that statistic. Usually lump my Hebrew friends in with us non-semantic peeps.

        I hadn't seen this book. Looks interesting. Hilarious that it drew such attention, and the people deconstructing the conclusions are doing so with logical/mathematic arguments that only the top two IQ categories are likely to follow. Even more interesting the deconstructing arguments assert the statistics are fallacious, but they are far stronger than the statistics for global warming and many statistics regarding income disparity. Clearly these are made to appeal to ready-made targets. I will have to read this. Thanks.

    This simple exam, which I could have done when I was in the 8th grade, is a test of one's abilities in science? Wait, I would have had to guess about cell phones, because I hadn't heard of them back then.

    A better test would ask, "Compute, by hand, the Fourier transform of this set of data points." Or "Name at least half the first 94 chemical elements." Or "Illustrate the mean, standard deviation, skew and kurtosis in hand-drawn graphs. Compare these measures to the physics of rotational inertia in simple terms." Or, "Explain, without conducting experiments, why it is a dreadful idea to mix bleach with ammonia or with vinegar. Give some of the possible reactions."

      It doesn't claim to test ability, just knowledge. But I agree with your criticism, since testing knowlege is not as useful an indicator of one's intelligence.

      Not sure the Astrology one is science either.

        Hell, I object when people call Economics "a science."
        !
        Ah, db... any problem with that kind of information Actually Belonging in Both Studies? :)

          Think your view comes from the observations that many people treat economics like astrology or religion, as beliefs, not objective cause-effect studies, developing conclusions from results of experiments (which is what all laws are...social experiments). In this I agree with you, but it need not be that way.

            Not exactly... I've recently finished reading three of the Freakonomics books.
            In their books, the authors have actually tried some experimental methods to try to discover root cause in a useful way, but from all I've seen, the Major People in Economics start with their Beliefs of How Things Should Be and then write column after column in the mainscream media trying to get everyone to agree that if Everyone Did It Their Way, All The Problems Would Be Solved...

            That's not experimental, nor imnsho, 'scientific.'
            Paul Krugman is one of my favorite examples.

            Economics tends to be backward-looking, often inferring a driving force that supports the economic philosophies of the economists. I view most Global Warming "consensus" the same way.

            Experiments in Economic Theory (scientific-style, that is) are extremely hard to create... partially because unless they're kept totally in the dark, the 'control group' would often object to their circumstances.. :)

              Being a fan, I think Milton Friedman's work is quite a bit more scientific than you describe. Perhaps we can agree that economics is immature, like chemistry in the 1600's.
              The element introducing chaos into these experiments is people (sociology), and beyond the fuzzy statistical nature of people's response, the data is clouded by politics and politician's manipulating the data. I find this quite like the churches manipulation of evidence to maintain power. This complication does not mean the study is impossible or unscientific. It does contribute to complication and unscientific manipulation.

                It turns out that my mind seems to work the same way as the Freakonomics guys' do. Frequently their writing and conclusions are incredibly congruent with conclusions I've reached on my own, and often years ago! I'm a fan, too...

                I've quoted and defended and proselytized Friedman over the decades, too! Met him in person, once, too. Tried to coax him into making a free-market position comment to a very liberal group and he refused. Pissed me off. Still love him. Remember, Friedman was just a wee bit pre-internet, so The Ways Experiments Can Be Run On People have changed a bit, too... :)

                  Jealous that you've met him! He died a few years after I really started to dig into this subject with vigor vs my inherent nature.

                    ... yep... back in the '80s, I think it was... and HE died way too early for MY taste... i'd wanted his ideas to be promulgated and accepted way more than they were (or are today).

                    I have a fond memory of a graph he did when writing for what I came to call "ANTI-BusinessWeek" magazine... a graph implying that whenever 'government' does something to change or provoke the economy, the real effects are not noticeable for 12-24 months or so later.

                    Just what was and is needed in the fruit-fly attention-span typical today in mainscream media and voters.

                    Oh, well... I turn 70 in two months. Won't have to up up with that shit much longer.... just gonna try to have fun....

    11/12 I missed the sugar and cavity question.

      When you see two variables (the axes), with a graph moving up and to the right, that indicates that as one variable increases, the other also increases. So, as sugar consumption increases, so do cavities.

        Backwards... the dots represent 'incidence of cavities' versus 'sugar consumption.' Those are the Inputs to the Discussion or Question...

        The line is more like a Least-Squares Fit to describe the average correlation between the two... which is the 'answer' or 'indicator' that when one increases, the other tends to increase.

    Oh Well, a Dummy among us. I always thought water boils at 212* no matter where I am and I can't hear for shit anyway. 10 of 12 and that is my final answer.
