Jubair Hasan Joy was inspired to write 'The Fascism Fallacy' after observing the political discourse during and after Bangladesh's 'Quota Reform' / 'Anti-Discriminatory' Protests, which led to the overthrow of the ruling Awami League party. He noticed the word 'Fascist' being used frequently and incorrectly, which he argues is not only wrong but dangerous. His interest in political theory was originally sparked by playing Europa Universalis IV, and his interest in logical fallacies began after losing an argument and deciding to formally study fallacies, cognitive biases, and psychological effects.

In his paper 'Navigating Grief and Loss in a Fast-Paced World,' Jubair Hasan Joy explores multiple philosophical perspectives on grief and meaning-making: Stoicism (focusing on what is within one's control), religious beliefs (faith-based approaches to loss), existentialism (creating one's own meaning in an absurd universe), and absurdism (embracing the tension between humanity's search for meaning and the universe's apparent meaninglessness). This reflects his broader academic interests in philosophy, logic, and political theory.
