Daniel Bar-Tal is an Israeli psychologist. His
studies and research are part of the social psychology area, from the basic
group structure to the particular conflicts that define some of them, like the
Israeli-Jewish society. Some of his work focused to the basics of the
socio-psychology is so well explained that my Social Psychology teacher uses
them as basic bibliography for the class. That’s where I read it for the first
time.
The concept of “group beliefs” is used to talk
about everything that defines a psychological group. If we want to say that a
group of people is a psychological group, they must share a lot of concepts,
values, goals, and well, beliefs, about themselves and the world around them.
This means they have to see thing in a similar way, if they want to understand
each other and live happily ever after, without the group breaking apart.
For example, if they like a soccer team, they
must all like the same one; if anyone likes another one, that person should not
be part of that psychological group, because his/her beliefs are different and
set him apart. Of course, this is only when the group existence is about
football. Maybe they don’t like the same music, but that’s not the reason they
are together, so, it doesn’t matter.
I like social psychology, and I like simple
things that have big implications. The “group beliefs” is a basic concept, but
it explains, in my opinion, a big part of how groups are born. I mean, Bar-Tal
explains that the most basic belief that must be shared is “we are a group”,
what can be more obvious, and a same time, more important?
Yeah...
