What could happen to people who refused to answer the question of the house none American activities committee?

Individuals who refused to answer questions from the House Un-American Activities Committee (HUAC) during its investigations in the mid-20th century could face several consequences. They might be held in contempt of Congress, resulting in fines or imprisonment. Additionally, their refusal could lead to blacklisting in their professions, particularly in the entertainment industry, significantly damaging their careers and reputations. This created a climate of fear and conformity during the Red Scare era.
