This paper treats the problem of which type of units, individuals or w
hole societies, should be used when explaining societal phenomena. It
is argued that factors operating at the individual level in principle
form societies, and that societal phenomena therefore should ideally b
e explained at this level. However, it is also argued that many societ
al phenomena cannot in practice be analyzed at the individual level in
a clear and strict way, but rather must be analyzed holistically, bec
ause it is not known how they are related to individual factors due to
the complexity of societies. For societies to be described and analyz
ed in a clear and strict way, they must as a rule be much simplified,
and such simplification is often made easier by abandoning the individ
ualistic perspective. If researchers still wish to describe a connecti
on between individual factors and a societal phenomenon, they often mu
st do so in vague terms. There are also other problems with the indivi
dualistic perspective that make it difficult to use. However, using th
e holistic perspective may be risky, as shown by two hypothetical exam
ples.
