We assess the impact of using social media to acquire political information on presidential approval. Building on the abundant literature that associates social media use with the reinforcement of views among people, we postulate a hypothesis that associate the use of social media to acquire political information with more extreme positions on presidential approval. We test the hypotheses using data from 9 national polls conducted in Chile between 2011 and 2021, a high-middle income country with widespread access to the internet and a budding use of social media. We find that acquiring political information on Facebook and Twitter is positively associated with lower presidential approval. This is especially strong in the case of right-wingers when there is a rightwing president.We assess the impact of using social media to acquire political information on presidential approval.

Com base na abundante literatura que associa o uso das redes sociais ao reforço de opiniões entre as pessoas, postulamos uma hipótese que associa o uso das redes sociais para obter informação política com posições mais extremadas sobre a aprovação presidencial. As hipóteses foram testadas usando dados de nove pesquisas nacionais realizadas no Chile entre 2011 e 2021, um país de renda média-alta com amplo acesso à Internet e uso emergente de mídias sociais. Descobrimos que a aquisição de informação política no Facebook e no Twitter (desde 2023, X) está  associada positivamente a uma menor aprovação presidencial. Isto é especialmente forte no caso da direita, quando há um presidente de direita.
