INTRODUCTION
The generally low level of science literacy has been a cause of concern for educators and policy makers for several decades. Surveys show that the U.S. general public has an imperfect grasp of basic scientific concepts, which affects individuals' ability to act as informed citizens in a world that is increasingly governed by issues of science and technology, as well as their ability to make reasoned judgments about issues like nuclear power, climate, genetic engineering, and the space program. Notably, science literacy has been tracked by the National Science Board (NSB) as part of the biennial Science and Engineering Indicators series (1979–2012), a report presented to the U.S. government, which is used to guide education and research policy. In the latest NSB survey (National Science Board 201225), less than one in three adult citizens correctly answered 8 or more out of 12 basic science knowledge questions, recognized astrology as nonscientific, and was able to describe adequately in their own words what it means to study something scientifically.
Astronomy educators are important players in the attempt to diagnose and improve this situation. Introductory astronomy college classes for nonscience majors enroll over 250 000 students per year and often represent a student's last formal exposure to science. Nationwide, about 10% of all students take such a class (Fraknoi 20029). Most teachers have goals that go beyond conveying astronomy knowledge and instilling an appreciation for the subject; they also want students to learn about the rational way of thinking and experimenting that has been so successful in revealing the underlying rules of the natural world. Constructivism, a theory of how people learn, posits that students do not enter the college science classroom as “empty vessels,” ready to be filled with scientific knowledge (Bransford, Brown, and Cocking 20002). Students have a complex web of prior belief systems and understandings about nature based on experience, upbringing, popular culture, and social interactions (Donovan and Bransford 20056).
The relationship between what someone “knows” and what they “believe,” and the basis for each, is subtle and complex and cannot be fully explored in this paper. Some beliefs are rational and align with scientific understanding, while others are largely or wholly irrational and can be classified as superstitions. Another category often is called pseudoscience: defined here as a belief system that presents itself as scientific or has some of the trappings of science, but is not based on logic or evidence (Shermer 199729). Pseudoscience claims, but does not uniformly possess, the attributes of logical rigor, evidence-based reasoning, predictive power, and empirical verification or falsification that are the hallmarks of science. Astrology is the archetypal example (Thagard 197831). As a result, the term is often used pejoratively. Knowledge is also a variegated concept. The process of science is one well-trodden path to knowledge, but knowledge also can be gained by experience or association and by transmission from another person or source. In this paper, we do not declare rigid distinctions between science and pseudoscience or faith and reason; the difficulty of doing so is the well-known “demarcation problem” in the philosophy of science (Resnick 200027). However, in the title and elsewhere we use the term “nonscientific” to refer to beliefs or knowledge that are not acquired through an application of commonly agreed upon tools of the scientific method (Gauche 200310). That is, nonscientific is not considered to be the same as antiscientific, and it is not intended pejoratively, since there are varied pathways to knowledge. However, many science educators have found that nonscience beliefs can interfere with the learning of science and hence with increasing overall science literacy (Losh et al. 200321; Martin 199423).
It is an open question whether or not nonscientific views or belief systems actually interfere with or compromise learning science and having a scientific worldview. Religious belief provides an interesting perspective. A survey by the Pew Charitable Trust shows that a third of all professional scientists adhere to a major religion and believe in a conventional Creator (Pew Research Center for People and the Press 200926). Faith and reason have coexisted in scientists as great as Newton, Planck, and Einstein, and there are prominent current examples like Francis Collins, Director of the National Institutes of Health. Perhaps surprisingly, only 40% of professional scientists in the U.S. classify themselves as atheists (Ecklund and Scheitle 20077). This may be an example of what paleontologist Stephen Jay Gould called the “nonoverlapping magisteria” of science and religion, where scientists can accommodate natural and supernatural worldviews without apparent conflict (Gould 200212). A majority of U.S. undergraduates sees no inherent conflict between science and religion, and the sense of a harmonious relationship tends to increase as they progress through their education (Scheitle 201128).
We have been surveying nonscience majors regarding their scientific knowledge, attitudes toward science, and pseudoscience beliefs for over twenty years. Initial results from the survey have been published in the last two years (Antonellis et al. 20121; Buxner, Antonellis, and Impey 20103; Impey 201016; Impey et al. 201117). Previously, we have used this extensive set of data of over 11 000 students to investigate the prevalence of beliefs in astrology, the proposition that the positions of celestial objects affect everyday life or are correlated with personality attributes (Sugarman et al. 201130). In this paper, we extend the analysis to encompass a wide range of nonscientific belief systems. Is acceptance of these belief systems an accurate gauge of scientific literacy? Do the pseudoscientific misconceptions coexist with scientific understanding? What are the implications for how we teach science in the college classroom? The first two questions are answered by this study, while the third question still has no simple answer, and so debate is likely to continue. In terms of scholastic aptitude test (SAT) scores and other academic indicators (College Board 20125), the University of Arizona is near the mean of the largest state universities, so we assume that our results are a fair indicator of similar college populations nationwide.
THE SURVEY
The survey instrument used in this study has been stable, using the same questions, since 1988 and has two parts. The first is based on, and has a substantial degree of overlap with, the instrument used by the National Science Foundation (NSF) in the biennial survey of public knowledge of science and technology. It is designed to measure general scientific knowledge using a set of 21 knowledge-based questions, four of which are open-ended with short written answers and 17 of which require true/false or multiple choice responses. The second part is original and is designed to measure attitudes about science and technology, perceptions of and susceptibility to some forms of pseudoscience, and certain aspects of faith and religious belief. It utilizes a set of 24 statements where the responses are on a five-point Likert scale. For a more detailed discussion of the instrument, its reliability and completion rate, plus a description of the data entry and coding process, see Impey et al. (2011)17.
The survey is administered each year to students in large astronomy lecture courses that consist mostly of freshmen and sophomores and satisfy the natural sciences General Education requirement at the University of Arizona. Administered in the first week of class, it is voluntary and does not count for any part of a student's grade. Ten to fifteen minutes are allowed for its completion. Although the survey is anonymous, a modest amount of demographic information is collected: gender, major, grade-point average, class standing, and the number of college science courses already completed. The survey is administered on paper, and subsequent data entry and coding are done manually. General characteristics of the sample are that the over 11 000 respondents are equally divided into men and women; the fractions of freshmen, sophomores, juniors, and seniors are 47%, 31%, 12%, and 10%; the largest three categories of major are business and professional (33%), social and behavioral sciences (21%), and fine arts and humanities (16%); and 41% of the sample had not previously taken any college science classes, while 12% had completed the General Education requirement of three one-semester long science classes intended for freshmen and sophomores (and not requiring labs).
The survey measures some aspects of science literacy with 17 forced-choice knowledge-based questions that cover a broad range of scientific subjects, from physics (“Which travels faster, light or sound?”) and astronomy (“Does the Earth go around the Sun, or does the Sun go around the Earth?”) to biology (“The oxygen we breathe comes from plants, true or false?”). In the analysis presented here, we used 15 of the 17 forced-choice questions to have maximum overlap with the NSB Science Indicators survey; the 15 questions used here include 9 that are consistently part of the NSB survey. From the answers to these questions, each student gets a score on a scale from 0 to 15, with each correct question worth one point. Four open-ended questions ask for definitions of the scientific method, DNA, radiation, and computer software; they were not used for the analysis in this paper.
Students also responded to a set of 24 statements on a five-point Likert-scale of strongly agree, agree, no opinion, disagree, and strongly disagree. A sampling of the items gives a sense of the range of topics addressed. Statements like “Pure science should be funded regardless of its lack of immediate benefit to society” and “Genetic engineering is a good idea” probe general attitudes towards science and technology. “We should make a concerted effort to search for life on other planets” addresses expectations in astrobiology, while a related item “Some ancient civilizations were visited by extraterrestrials” alludes to belief in unidentified flying objects (UFOs). Others such as “There are some circumstances when medical science should not be used to prolong life” address ethical issues. Another set of items probes superstitions and beliefs in pseudoscience; examples include “Some numbers are especially lucky for some people” and “The positions of the planets have an effect on everyday life.” There are also statements that relate to religious belief, such as “The Biblical story of creation should be taught alongside evolution in our schools” and “Faith healing is a valid alternative to conventional medicine.” The survey is shown in Appendix A.
Some caveats and qualifications are in order. It is not possible to capture the nuances of any individual's science beliefs and knowledge in a fifteen-minute survey. Nor is it possible to combine such results into an “identikit” picture of the beliefs and knowledge of a population; the variance of responses on any particular survey item is large, so information is lost in forming means or looking for trends. Moreover, items in the survey are not uniformly strong and do not have equal diagnostic power. This is not as much of a problem with the forced-choice and open-ended science knowledge questions, which have been used and validated by the NSB for over two decades, as it is for some of the attitudinal Likert-scale statements. For example, “The universe was created in an enormous explosion billions of years ago” might elicit student disagreement because they did not agree with the scientific story of creation or because they did not agree with the overly declarative phrasing (or because they recognized that an explosion is a poor analogy for the instantaneous creation of all space-time). Similarly, a student might concur with the statement “UFOs are real and should be investigated” because they think alien space ships have visited the Earth or because they think that unidentified aerial phenomena are worthy of further study. Disagreement with positive statements about genetic engineering and nuclear power might arise from lack of information and antipathy or from a balanced judgment based on a high degree of information. Nonetheless, we contend that the survey has utility in the aggregate, and for example, as we will show in Section 4, the items that relate to pseudoscience have diagnostic power as a group.
OVERALL RESULTS
Before analyzing the landscape of beliefs and their relationship to science knowledge, general results from the survey can be summarized. There are no major changes in student response over the more than two decades of data, so we collapse the time axis to use the statistical power of the entire sample. As reported by Impey et al. (2011)17, University of Arizona undergraduates scored an average of 7.2 out of 9 correct (80%) on the knowledge items the survey has in common with the NSB survey, compared with 5.6 out of 9 (62%) for adults in the general public. Overall, students scored 11.2 out of 15 correct (75%) on the forced-choice knowledge items of the survey. Freshmen performed 20–30% better than the public on most of the knowledge items, with the exception of the questions about evolution and the big bang, where the gains were 50–60%.
As seen in Figure 1, aggregate improvements over the course of an undergraduate career (based on class standing rather than tracking cohorts) are no more than 5–10% for all items except for understanding about lasers, with an increase of 15%, and understanding of antibiotics, with an increase of 22%. Additionally, there was an increase of 30% in correct responses to the astrology question between freshman and seniors. Due to well-known issues with students' confusion with the words “astrology” and “astronomy,” this question was not included in the science literacy analysis of this paper. For a full discussion of this aspect of the survey and students' conceptions of astrology related to this study, see Sugarman et al. (2011)30. Completion of the college science requirement leads to very little improvement in science knowledge score. Educators cannot be satisfied with a situation where one in three graduates thinks antibiotics kill viruses as well as bacteria, one in four thinks that lasers work by focusing sound waves, and one in five thinks atoms are smaller than electrons, are unaware that the Earth goes around the Sun, or that humans evolved from earlier species.

The attitudinal part of the survey reveals a rich landscape of beliefs, where strong support of science and its agenda coexist with a susceptibility to nonscientific thinking or modes of thought like pseudoscience, which do not fare well when subjected to skepticism and evidence-based reasoning. On the plus side, 93% strongly agreed or agreed with the statement that “Overall, the progress of science and technology has been beneficial to our civilization.” Reassuringly for astronomers, who use taxpayer dollars to study objects and processes that can seem esoteric to a layperson, four times more students agreed rather than disagreed with the statement “Pure science should be funded regardless of its lack of immediate benefit to society.” There was also solid support for astrobiology and NASA; half strongly agreed or agreed that “We should make a concerted effort to search for life on other planets,” and two thirds similarly affirmed that “The government should strongly support the manned space program.” The distribution of responses to these questions can be seen in Figure 2.

However, other Likert-scale items show that college students did not uniformly embrace a purely rational worldview. More than two thirds strongly agreed or agreed with the contention that “There are phenomena that physical science and the laws of nature cannot explain.” Care must be taken not to over-interpret such an item, since respondents might be thinking of phenomena that involve human behavior, such as the behavior of stock markets, or emotional states such as sadness and love. At the very least, the responses conveyed a strong sense that the explanatory reach of science is limited. In the realm of pseudoscience, significantly more students agreed than disagreed with the statements that “The positions of the planets have an influence on the events of everyday life” and “Some people possess psychic powers.” In the realm of superstition, more than a quarter thought that “Some numbers are especially lucky for some people.” On the topic of life in the universe, over half strongly agreed or agreed with a statement that “It is almost certain that there are intelligent life forms elsewhere in the universe.” Many astronomers might concur since the prevalence of potentially habitable exoplanets increases the probability that some of them will host intelligent life. However, scientists would diverge from students in the conclusions they drew from the existence statement, where one in three students thought “UFOs are real and should be investigated” and one in six thought “Some ancient civilizations were visited by extraterrestrials.” See Figure 3 for a distribution of student responses to these questions.

This survey is not designed to measure religious belief, which is multifaceted and complex. However, it contains three items that address aspects of faith in the Christian tradition, and in particular its more conservative and fundamentalist strands. Nearly 40% of all undergraduates strongly agreed or agreed that “The Biblical story of creation should be taught alongside evolution theory in our schools,” while less than a third disagreed or strongly disagreed with that statement. The minority of dissenters are supported by the U.S. Supreme Court, which has ruled that creationism does not belong alongside evolution in the science classroom, in Edwards vs. Aguilard (1987)8. The statement taps into substantial disagreement; the standard deviation on the Likert scale is the largest among all 24 items. About one in four students responded that “Faith healing is a valid alternative to conventional medicine,” a position that is not supported by the American Medical Association (Hafner 199313). The incidence of Biblical literalism, however, appears low in this student cohort as only 15% disagreed with the statement that “The universe was created in an enormous explosion billions of years ago.” As noted previously, some within that group may have disagreed not based on religious grounds but because the statement is unequivocal while the evidence for the big bang is based on inference about remote realms of time and space. See Figure 4 for a distribution of student responses to these questions.

CATEGORIZING BELIEFS AND ATTITUDES
For a deeper level of scrutiny of the data, and to connect measurement of science knowledge to measurement of attitudes and beliefs, we looked for commonalities among the Likert-scale items. As a first step, the three authors and three other young education professionals in our team each grouped the items into a small number of categories based on what each saw as the common themes underlying them. After sharing our rationales for why we each grouped items as we did, we agreed that they all fell into five categories: belief in nonscientific phenomena, positive attitude toward science and technology, belief in UFOs and aliens, ethical concerns about science and technology, and faith-based beliefs. The items associated with each of these initial categories are listed in Table 1.
With this grouping as a prior expectation, we undertook an exploratory factor analysis on a random subsample of the data for all 24 items. This process helps empirically determine if the original 24 questions can be grouped together or reduced into categories because multiple items tap into similar student ideas. In this procedure, a grouped set of items that is found to strongly correlate with one another, but not with other items, is called a factor. From this initial exploratory factor analysis, we compared items that loaded onto factors to the original categories that we had derived and adjusted the categories accordingly, including dropping several items. We then used confirmatory factor analysis to test the new model and finalize the categories of responses. A forthcoming companion paper (Buxner, Impey, and Antonellis 20124) includes a full description of this analysis.
Table 2 shows the items that were retained for each of the factors, along with the original factor loading scores from the exploratory factor analysis. Based on these loadings and the model fit of the confirmatory factory analysis, only four of the original categories were retained: belief in life on other planets, faith-based belief, belief in unscientific phenomena, and positive attitude towards science and technology. In confirmatory factor analysis, the quality of a model is assessed based on how well the model accounts for the observed relationships in the data set. In this type of comparison, there is no one single measure that indicates this relationship, but rather a set of fit indices that researchers use as a barometer of overall fit. The final fit of the model was acceptable for several indicators of fit. Values of fit for the model were: goodness-of-fit index (GFI) = 0.96, adjusted goodness-of-fit index (AFGI) = 0.92, comparative fit index (CFI) = 0.89, normed fit index (NFI) = 0.88, and root-mean-square residuals (RMSR) = 0.07. For the first four indices, values closer to 1.0 indicate better fit of the model to the data, with a general rule of thumb of 0.90 being an indicator of good fit. For the RMSR, smaller values are used of evidence of good fit. Responses to items within each factor are correlated, and this analysis is a quantitative way of seeing some of the contours of the “landscape” of student attitudes and beliefs. Additionally, binning these items into categories allows us to see how students' beliefs are related to their science literacy scores.
One of the most striking results of the survey so far has been the fact that the science knowledge score and attitudes and beliefs varied so little with passage through an undergraduate degree or with the number of college science classes taken (in the aggregate, rather than for a particular cohort). This implies that the bulk of a young adult's information and attitudes towards science is formed before they leave school. Similarly, and surprisingly, we find little correlation between science knowledge score and attitudes or beliefs. For example, students who thought that astrology is scientific did not score substantially lower on the science literacy questions than students who thought it is nonscientific (Sugarman et al. 201130).
To get the most leverage on this issue, we looked at the mean science knowledge score for students in the margins of the distributions for each of the four factors on the attitudes and beliefs part of the survey. Students with a mean factor score of 4 (agree) or higher were compared with students with a mean factor score of 2 (disagree) or lower. The results are given in Table 3. Differences between groups were tested using independent t-tests. Results with significance (or p) values below 0.05 indicate a statistically significant difference between groups. Statistically significant differences in science literacy scores were detected for students for both those with very high and very low mean scores for faith-based beliefs (t (4823) = 17.0 p < 0.001), a mean difference of 1.1 questions, and those with very high and very low mean scores for unscientific beliefs (t (3054) = 9.7, p < 0.001), a mean difference of 0.8 questions. Only small differences were found for the other two factors. A multiple regression was used to investigate the relative contribution each variable had on students' science literacy score. Results with significance (or p) values below 0.05 indicate a statistically significant difference between groups. The r2 value is a measure of effect size, which indicates the amount of variance in the outcome (students' science literacy scores) explained by the predictors (students' beliefs). A multiple regression revealed a small effect of students' beliefs on their overall science literacy score, with an overall explained variance of less than 4% (F (4, 9852) = 97.1, p < 0.001, r2 = 0.038).
DISCUSSION
NSF's Science and Engineering Indicators provide an important context for understanding the prevalence of nonscientific beliefs among members of the U.S. public. The section on belief in pseudoscience from the 2006 report (National Science Board 200624) leads with a very succinct statement about the issue: “Although science and technology are held in high esteem throughout the modern world, pseudoscience beliefs continue to thrive. Such beliefs coexist alongside society's professed respect for science and the scientific process.” An analysis of 20 years of NSF data concluded that belief in astrology, lucky numbers, extrasensory perception, and UFOs as alien spacecraft were widespread (Losh et al. 200322). Roughly one in three American adults believes in telepathy, ghosts, and extrasensory perception, and roughly one in five believes in witches, astrology, clairvoyance, and communication with the dead. Three quarters hold at least one of these beliefs, and a third has four distinct pseudoscientific beliefs.
In discussions among scientists and educators, it is often assumed that pseudoscience belief stems from a lack of critical thinking skills and that pseudoscience belief is negatively correlated with science knowledge and an understanding of how science works. For the analysis described in this paper, those conjectures were hypotheses to be tested. In addition, we were interested in how pseudoscience beliefs change during progress through the undergraduate experience, and whether or not susceptibility to pseudoscience is related to religious belief.
Although we see small differences in the performance of students who held strong faith-based beliefs or strong beliefs in unscientific phenomena, these corresponded to about a one point difference, out of 15, in science literacy. This difference is less than the difference we see between science and education majors in the sample, which corresponds to an average of two points out of 15 on the science literacy scale. We also see relatively small reductions in pseudoscience belief over the course of an undergraduate career that includes at least three science courses. Confused signs of the nature of any relationship between formal education and pseudoscientific thinking have also been noted elsewhere (Goode 200211).
These generally null results present a challenge to educators. If nonscientific ways of thinking are widespread and resistant to standard modes of instruction, do educators need to be concerned and what do belief systems have to do with efforts to create a citizenry that is informed enough to vote on issues that involve science and technology? Some commentators have contended that pseudoscience and the paranormal are often skirted in the classroom, or treated as taboo subjects, meaning that nonscientific belief systems are not confronted (Martin 199423). Another point of view holds that pseudoscience beliefs cannot be addressed without classroom content that is relevant to societal issues (Hobson 200015, 200814). But psychologists Lindeman and Aarnio (2007)19 find support for a conceptual framework where a variety of superstitious, magical, and pseudoscientific beliefs accrue from the same kind of ontological confusion, and analytic thinking coexists with nonscientific forms of intuitive thinking. Moreover, research shows that people tend to motive their reasoning process based on prior beliefs and biases (Kunda 199018), and those with the strongest opinions on complex societal issues are highly selective in their consideration of relevant evidence (Lord, Ross, and Lepper 197920). Both of these effects mitigate against a completely rational world view. Religious beliefs exist in a distinct realm since they are based on faith. They may be similarly decoupled from aspects of worldview that are associated with evidence and causal connection, explaining the weak relationship seen here between religious belief and science knowledge. Improving science literacy will require a more nuanced approach that takes account of this psychological landscape. Since we also have found that science knowledge and attitudes are not substantially altered by the college experience, we have embarked on a separate study to understand where young adults get their information about science and technology.
