“Do you know more about science and technology than the average American?” Mephitic scholars at the Pew Research Center want to know. They have a 13 question test for your amusement.
The first 4 are true false. All radioactivity is man-made. ~ Electrons are smaller than atoms. ~ Lasers work by focusing sound waves. ~ The continents on which we live have been moving their location for millions of years and will continue to move in the future. 5 is multiple choice. The first 9 are easy.
The first one where PG had to think was 10. Which is an example of a chemical reaction? Water boiling ~ Sugar dissolving ~ Nails rusting. The demographics were gender, age, and amount of education. It did not take long to complete the test.
PG got 13 of 13 correct. “You scored better than 93% of the public and the same as 7%.” If you have too much free time, you can see a report.
The survey was conducted over the phone, using randomly generated phone numbers. Half the calls were on land lines, and half were on cell phones. In land lines, the interviewer asked for the youngest person, over 18, in the house. In cell phone interviews, the person answering the phone was interviewed. Quotas were used for gender, age, and education groups.
