Why study psychology?
Psychology not only helps you understand why people (and animals)do
the things they do, but it also helps you better understand yourself and
your reactions to others. Psychology can help you comprehend how
your brain and body are connected, how to improve your learning
abilities and memory, and how to deal with the stresses of life, both
ordinary and extraordinary. In studying psychology, an understanding
of the methods psychologists use is crucial because research can be
flawed, and knowing how research should be done can bring those
flaws to light. And finally, psychology and its research methods
promote critical thinking, which can be used to evaluate not just
research but also claims of all kinds, including those of advertisers and
politicians.

need to be subjected to testing.
2. All evidence is not equal in quality.
3. Just because someone is considered to
be an authority or to have a lot of
expertise does not make everything
that person claims automatically true.
4. Critical thinking requires an open mind.
