  • The Psychology Behind Why Some are Hesitant to Get Vaccinated to Slow the Spread of COVID-19 and the New Delta Variant

    Just as I said in the mask hesitancy episode (episode 5), we mustn’t call those that are hesitant of the vaccines “anti-vaxxers,” for the term is derogatory and in many cases, categorically untrue. Instead of blaming the Republicans, the Democrats, the conservatives, and the liberals, we are going to explore the actual, non-political and political reasons for which Americans, and all humans, are hesitant to get vaccinated against COVID-19. In this episode, the perfervid debate over the vaccine will be simplified into a matter of human psychology, not political disposition.
