“…Many papers have studied how government response such as movement restrictions can contain the virus spread and death (Baccini and Brodeur 2020; Bargain and Aminjonov 2020;Béland, Brodeur, and Wright 2020;Moser and Yared 2020;Yilmazkuday 2020; among others), but we join Bargain and Aminjonov (2020), Briscese et al (2020), Chen, Frey, and Presidente (2020), Nay (2020), Litan and Lowy (2020), Nikolaev, Boudreaux, and Salahodjaev (2017), and Schwartz (2012) among others in considering how personal freedoms affect the spread of COVID-19 or vice versa. Motivated by Cutler and Lleras-Muney (2010), Lleras-Muney (2005), and Conti, Heckman, and Urzua (2010) on the important relationship between education and health, and by Leung et al (2003), Tang and Wong (2004), Bawazir et al (2018), Barr et al (2008), Bish and Michie (2010), and Rosenberg et al (2013) among others on the importance of science education, in processing facts and making decisions, we study how young adults' way of thinking mathematically and scientifically separately affect the spread of COVID-19 by using Programme for International Student Assessment (PISA) scores. The acquisition of knowledge in mathematics and science by young adults attained in secondary education is a part of the total social system.…”
