What are the simarities between Sociology and Psychology?

these both Word starts with "P" of English alphabet..........

Aside from that Psychology is "Grounded in Science" meaning that all psychological assertions and discoveries are based completely on observable and empirical data. and content ranges from how things we perceive effects behavior, to learning and conditioning and beyond.

Meanwhile philosophy (as far as I know) is more concerned with the construction of arguments, and wrapping the mind around large questions.

many of today's ways of thinking came from from philosophers of yesterday, concepts of the "Self" and and society etc. Many of today's other realities have stemmed from psychology research including advertising techniques, styles of teaching and learning, etc.
