The Projection Bias

The tendency to assume that others share similar values, beliefs or thoughts.

Here are three types of projection:
• Complementary projection is assuming that others do, think and feel in the same way as you.  Thus we see our friends as being more like us than they really are.
• Complimentary projection is assuming that others can do things as well as you.
• Neurotic projection is perceiving others as operating in ways one finds objectionable in oneself.

Being aware of psychological projection in interpersonal relationships is very important. Before attributing thoughts or ideas to someone else, you may want to reflect on whether those beliefs can also be seen in yourself.
