Repressive apparatus uses violence and fear to control individuals. Using police, the courts and jails as a weapon to instill compliance. A repressive system restrains the freedom of individuals and groups.

 Ideological apparatuses use a set of standards to influence people it uses schools and mass media to control individuals by enforcing they’re standards for example you go to school and learn to raise your hand to talk. 

While ideological uses a set of standards to influence obedience. A repressive uses fear and threats of violence to control people.  

An example of ideological apparatus is a song by the black-eyed peas called Where is the love. The songs touches on many political topics including war, racism, and pollution. It speaks on unity in the face of civil unrest. It questions why we lack the understanding for one another. 

Ideology is a set of beliefs or ideas we have around society or specific groups. These beliefs and ideas influence the way we think about politics and societies, but it also influences the way we think about ourselves and our peers.

Conservative ideology want a weak government and a strong authoritarian state, they support harsh policing and they push self-reliance, meaning they don’t believe the poor should get hand-outs from the government they believe the poor should work hard even if the disadvantage is because of the downward economy, they would like to preserve traditional privilege and practices. They believe in making profit off another people’s labor. They don’t want the government involved in business regulations. They also believe religion should pushed in schools and mandatory in everyday life. While Liberal ideology is believing in reforms and regulatory processes. They agree with free trade and globalization because while it does benefit corporations it also benefits individuals. Unlike conservatives they would like to improve public services and environmental protections. They are more for individual rights. The big difference is how much or how little each party wants the government involved  

Althusser believes that ideology is accepting beliefs that you believe without knowing you believe them, but he also believed it was a controlled behavior either by a repressive or ideologic apparatus.
