Is there scientific bias which brings a willingness to lie to support theory?

Everytime a new revelation of fraud comes out in science- Facts of Lucy, Nebraska man, and even on global warming- do those who look to people have a harder time looking to scientific theory as fact? Scientists once taught the earth was flat and the center of the universe. It once taught that monkeys were directly in our evolutionary chain- till it no longer made sense that they didn't evolve within our chain of time. What will you continue to believe in the ever-changing theories of science?
