Assumptions and Psychology

I recently talked to a friend about Psychology, and she claimed that Psychology is a lot of trash... I tend to not agree with this assumption. This is something I will have to study in great depth to be an Occupational Therapist, and I think it's wrong to roll everyone in a profession into one group. That's like saying that every doctor is brilliant, or every truck driver is bad news (that is not to say that every doctor is stupid or every truck driver is kind). There might be some groups of people that are all the same, but often there are different sides to each group. For example, there are three types of Muslim's. There are the average Muslim's (The majority of them) who claim to be Muslim's, but don't actually follow the teachings of Mohammed. (Jihad). Then there are the Traditional Muslim's, who want to follow Mohammad, but are either unable or afraid to. The last group are the Fundamentalist Muslim's, who actually follow the Jihad teachings. (If you know anything about the teachings of Muslim's, and the way that they decide which laws to follow, you will realize that those who are Jihad Muslim's are actually the real Muslim's)

In many ways, everyone is a Psychologist. Basically you are like a Profiler. You make assumptions of people based on what you observe about them... You might see someone wearing clothes with paint and stains on them and assume that the person is a house painter. Maybe you see someone shopping, and observe that in their shopping cart they have diapers and baby powder, so you assume they have a baby at home. People make assumptions based on so little all the time... Isn't that akin to Psychology? I think so... Just a thought.
