Objectivity in Science

There is a common myth that scientists is that they are totally objective but it is not true. First of all scientists human and are subject to human flaws that prevent total objectivity. In addition ones philosophical assumptions will always influence ones conclusions no mater how objective you try to be.  Furthermore just knowing something about the topic will inevitably causes a person to form opinions about that topic such that you can only be totally objective if you are totally ignorant. 

Take a look at the following video and notice how the blue ball moves.

Most likely you concluded that the gravitational attraction of the larger ball or some other physical force was pulling on the blue ball making its path bend. If you did you have just let your own preconceptions about the real world cloud you thinking about an animation video. The real answer is that I drew the frames of the video to make it do that.
