Cultural Cognition Rank yourself from 1 – 10. 1 means you absolutely disagree. 10 means you absolutely agree. Write your answers down somewhere. You‘ll need to add them 1. The government interferes too much in our everyday lives. 2. Government needs to make laws that keep people from hurting themselves. 3. The government should stop telling people how to live their lives. 4. The government should do more to advance society's goals, even if that means limiting the freedom and choices of individuals. 5. Too many people today expect society to do things for them that they should have to do for themselves. 6. People should be able to rely on the government for help when they need it. 7. Society works best when it lets individuals take responsibility for their own lives without telling them what to do. 8. It's society's responsibility to make sure everyone's basic needs are met. 9. People who are successful in business have a right to enjoy their wealth as they see fit. 10.

Cultural Cognition Rank yourself from 1 – 10. 1 means you absolutely disagree. 10 means you absolutely agree. Write your answers down somewhere. You‘ll need to add them up. 1. Our society would be better off if the distribution of wealth was more equal. 2. Nowadays there is as much discrimination against whites as against blacks. 3. We need to dramatically reduce inequalities between the rich and the poor, whites and people of color, and men and women. 4. It seems like blacks, women, homosexuals and other groups don't want equal rights, they want special rights just for them. 5. It's old-fashioned and wrong to think that one culture's set of values is better than any other culture's way of seeing the world. 6. The women's rights movement has gone too far. 7. We live in a sexist society fundamentally set up to discriminate against women. 8. A lot of problems in our society today come from the decline in the traditional family, where the man works and the woman stays home. 9. Parents should encourage young boys to be more sensitive and less rough and tough. 10. Society as a whole has become too soft.
