Psychology is not based on Freud, or Jung, or attempting to
be psychic. (Though, you're one of the lucky few if you study psychology and someone doesn't ask how to read minds.)
Psychology is the study of what we do think, how we think, and what
determines our behaviour, emotions and actions. It’s the science of human
nature.
And yes, it is a science. By no means is it perfect, but
neither are any of the “natural” sciences, and some areas are definitely more
of a social science, but psychology is a scientific discipline. We use experiments, observations, and
statistics. We measure heart rate, eye movements, galvanic skin responses,
electrical activity in the brain and blood flow. We attempt to find how
mechanisms work, to find general laws and exceptions to those laws, to build
knowledge in order to help others, understand the world better, and find
applications. We learn about physics, chemistry, biology and maths in relation
to the body. This is psychology in the twenty-first century, and it is about
time people started to take note.
The way that the media uses psychological knowledge is for
shock value. Correlational studies told to demonstrate cause and effect when
they only show relationships, mild effects blown out of proportion, and studies
of little value but less ethical or more thrilling get put into the limelight,
whilst some truly excellent ones only get reported in the essays of
undergraduates.
I took psychology because I’ve always wanted to help people;
to make a difference. But in the three years I’ve been studying it at an
academic level, it’s made me rethink the way I think about the world. I’m more
critical, more aware, and I understand my behaviour and why others do the
things they do.
The thing about it is, we cannot be one hundred per cent
objective about our behaviour, and yes, it’s difficult to prove theories even
with substantial evidence. These are the cries of critics, and the sorrowful
admittances of psychologists. Yet, this is true of everything. As humans, we do
the best with the knowledge we currently have, and this is true of the causes
of disease and the big bang theory to how life was before Homo sapiens, and in
ancient civilisations.
Why do people judge psychology, then? Different reasons, for
which I speculate are from a mixture of misinformation about what psychology involves
and attempts to achieve, normative and informational influence from others,
self-enhancement, and scepticism.
But, before you regretfully accept the scorns and mocks of
others for not taking a “proper subject/science”, remember this: psychology is
the science that provides knowledge for medicine, biology, sociology, politics
and education alike. It is the field which attempts to remedy psychological
disorders, provide better well-being, and aid understanding. It helps, and it’s
worthwhile.
