In surveys conducted in 2005, people in the United States and 32 European countries were asked whether to respond "true," "false" or "not sure" to this statement: "Human beings, as we know them, developed from earlier species of animals".
Sixty-three percent of students who completed the post-course questionnaire responded "true" to the statement "evolution is a scientific fact".
The results indicate that students who responded "true" to the statement achieved significantly (p = 0.002) higher marks on the quiz.
Students were asked to respond "true" or "false" to a series of statements regarding specific questions surrounding misconceptions and the acceptance of evolution (Table 1).
Miller et al. (2006) collected data for a survey in which participants were asked to respond true or false in one format or definitely true, probably true, probably false, or definitely false in another format to the statement, "Human beings, as we know them today, developed from earlier species of animals".
Participants were asked to respond true, probably true, never thought about it, probably false, or could not possibly be true, to the question, "Do you agree or disagree with Darwin's theory of evolution?" Countries with less than 999 respondents were Kazakhstan (970), Malaysia (803), and Egypt (786).
Examining the post-course quiz results, final examination results, and the final results for the overall topic, we found that the group that responded "true" to "evolutionary theory is the only theory that adequately explains the diversity of life on Earth" significantly outperformed those who responded "false".
In addition, 44percentt responded true when asked if "private policy means company keeps users info confidential".
It was, therefore, essential that we exclude subjects who could not consistently respond "true" or "false" with conviction.
