Studije diljem Europe pokazale su da se ljudi u ranim fazama pandemije COVID-19 nisu u potpunosti pridržavali preventivnih mjera i preporuka koje su dale vlasti. Kao što je vidljivo, stope usklađenosti mogu ovisiti o mnogim različitim čimbenicima, uključujući osobine ličnosti, spol, dob, pa čak i iracionalno vjerovanje u teorije zavjere. Ovi nalazi naglašavaju heterogenost među ljudima i, u kombinaciji s uvidima iz teorije igara i eksperimentalne ekonomije, sugeriraju da bi bilo teško održati visoke stope usklađenosti i spriječiti širenje smrtonosnog virusa bez uvođenja strožih mjera koje su kasnije usvojene. Studies across Europe have shown that in the early phases of the COVID-19 pandemic people did not fully comply with preventive measures and recommendations given by the authorities. As evidenced, compliance rates may depend on many different factors, including personality traits, gender, age, and even irrational beliefs in conspiracy theories. These findings highlight heterogeneity among people and, in combination with insights from game theory and experimental economics, suggest that it would be difficult to sustain high compliance rates and prevent the spread of the deadly virus without imposing stricter measures that were adopted later.
