The political twittersphere as a breeding ground for populist ideas: The case of Israel

This study employs a neural network approach to investigate the dissemination and content of populist ideas within the Israeli political Twittersphere. By analyzing a dataset of Twitter activity by Israeli lawmakers from 2013 to 2022, the study reveals a consistent increase in the frequency and concentration of populist ideas, particularly among legislators from religious-nationalist parties. The analysis of the topical content of populist ideas spread on Twitter highlights the significant impact of legal proceedings against the Prime Minister on political discussions. It delineates the development of a Manichean discourse among the center-left and a complete populist cosmology among the right, reaching its peak in 2022. The study demonstrates the utility of such approaches in understanding the evolution and dissemination of populist ideas, as well as the challenges faced by the backsliding Israeli democracy.
