*Psychological ScienceHow can we differentiate between uninformed opinions and examined conclusions?The science of psychology can help make these examined conclusions, which lead to our understanding what people feel, think, act, as they do!
*The Scientific AttitudeThe scientific attitude is composed of curiosity (passion for exploration), skepticism (doubting and questioning) and humility (humbleness to accept when wrong).
*Critical ThinkingCritical thinking does not blindly accept arguments and conclusions.
It examines assumptions, discerns hidden values, evaluates evidence, assesses conclusions.The Amazing RandiCourtesy of the James Randi Education Foundation

*Hypothesis is a testable prediction, often induced by a theory, to enable us to accept, reject or revise the theory.

Ans: Even when specific attitudes and behaviors vary across cultures, as they often do, the underlying processes are much the same.Ami Vitale/ Getty Images
