Beg to differ, Josie, on several points.

First of all, we don't _inherit_ intellectual and cultural "traits" via DNA. We can have traits like quick thinking, methodical thinking, etc. which may be inherited, but we learn about the world and so so from a cultural standpoint. What we learn is not set in stone. Unlike animals, humans are extremely malleable. We have a rational soul and are able to choose freely. We have very few (if any) instincts.

Bias is consistent. You can have points of view depending on your life experience, gender, social class, race, etc. That's not the same as bias. As I pointed out above, the US media has a consistent bias in favor of business.

Bias connotes unfairness and is related to prejudice. If the newspaper consistently favors, for example, business interests over the interests of the poor unemployed, that's unfair coverage. The bias prevents the reporter from even _seeing_ that there's another side to the story. The story will talk about development, profit, and job creation. It will probably not talk about fair wages, fair treatment of employees, work schedules, etc.

It's also prejudging (prejudiced) in the sense that the reporter has developed a standpoint based on what the news outlet wants. US media get into trouble when they upset businesses that advertise. Thus, a bias in favor of business makes sense to corporate US media.

With regard to your "Going against straight party-line thinking", I'd call that independent thinking rather than bias. It's what everyone should do.
