How are public policy decisions made?

Are the made based on what voters want?

Are they made to avoid risk entirely or do they involve a balance of risk and benefits?
Or do they include substantial risk? I am not sure.

Read widely and take good notes.
I found the answer which was no thanks to this link. It involve a balance of risks and benefits.
